FOREWORD

We would like to thank you for purchasing a highefficiency Firebird C Range Condensing domesticcentral heating oil fired boiler. This instructionmanual is produced for the reference andguidance of qualified installation engineers such asthose who are OFTEC registered. EU legislationgoverns the manufacture, operation andefficiency of all domestic central heating oilboilers. Our boilers and burners will are suppliedas matched units tested and approved to OFTECStandard OFS Al00.

FIREBIRD Boilers are full manufacturing membersof OFTEC (Oil Firing Technical Association) andare participating in its Boiler testing and approvalsprogramme to comply with OFS A100 and ECEfficiency Directive.

You should ensure that all installation, servicingand commissioning works are carried out by acompetent person, such as one registered byOFTEC. It should be noted that it is theresponsibility of the Installer/Householder toensure that the boiler is properlycommissioned. Failure to do so may invalidatethe boiler guarantee and any extendedwarranty.

SERVICINGThe boiler requires servicing on an annual basisto ensure it maintains its efficiency, continuesto perform reliably and as a regular check onits built-in safety features. It is important thatservicing should be conducted by a competentengineer, such as one who is OFTEC trainedand registered.

All appropriate OFTEC manuals and BSStandards should be studied and theirrequirements adhered to and used inconjunction with these instructions. Thismanual includes a list of some BS Standardsand Building Regulations.

OFTEC is conducting training and registration ofengineers and this is to be commended, asreading of this manual alone for installation andservicing procedures cannot replace the criticaladvantage provided by training and years ofexperience.

INTRODUCTION

Firebird domestic oil fired condensing boilers arehighly efficient and are all independently certifiedto Sedbuk Band A. They use less fuel and havelower running costs than non-condensing boilers.Because of their increased efficiency they emitless carbon dioxide than non-condensing boilers,which will contribute to efforts to reduce globalwarming. The incredible efficiency of the FirebirdC Range Condensing Boiler is due to thedevelopment of a single boiler unit with threeunique heat exchanger units. This gives aexchange surface greater than non-condensingboilers.

This additional surface area increases the amountof heat extracted from the combustion processand thus reduces the heat wasted to atmosphere.So much heat is extracted from the combustiongases that their water vapour element condensesinto liquid form, releasing the latent heat that wasused to create the vapour in the first place. It isthis heat gain that gives the condensing boiler itssignificant advantage over a non-condensingmodel. In order to enable this high level of heatextraction to take place, the water in the boiler’sheat exchanger must be cooled down to about55˚C or less, this means that the boiler isworking at its maximum efficiency.

The condensate produced is often mistakenlyconsidered to be highly acidic. In fact the acidity ofcondensate from a Firebird C Range CondensingBoiler will be found to be as low, if not lower, thanthat of vinegar.

A 20˚C. differential between flow and returnshould be maintained to achieve maximumperformance from the Firebird C RangeCondensing Boiler.

The Firebird C Range Condensing Boiler issuitable for underfloor heating provided thereturn temperature is above 40˚C. at all times.

The Firebird C Range Condensing Boiler evenwhen not working in condensing mode will stilloperate at extremely high efficiencies making itsuitable for fitting to an existing heating systemwithout alteration to the radiator sizes.

The burner is factory set for use withkerosene 28 second class C fuel.

PROGRAMMING GUIDE

SETTING UPThe outer dial should be set tothe current time. Rotate the dialslowly in clockwise direction,until the correct hour is alignedwith the arrow head printed onthe dial. Note that the outer dialis printed with the 24 hour clock - 8:00 a.m. = 8 on the dial.8:00 p.m. = 20 on the dial.

Do not attempt to rotate the dialin an anti-clockwise direction.

Central Heating Control

The control panel is designed for simplicity of use and isequipped with adjustable thermostat dial, optionaltime controls and limit thermostat reset button asshown above. It also has a built in system pressuregauge which is connected to the boiler and heatingsystem water at the safety valve.

When replacing make sure that each thermostatpocket receives correct phial by marking and notingcarefully each phial and its correct pocket.

MANUAL SWITCHManual switch operation: The manual switch willprovide Fixed On / Fixed Off / Auto control, therebyallowing manual control of the switched outputwithout disrupting the timed (tappet) settings. Pleaserefer to the illustration above.The slide switch can be set in one of the three positionsavailable ‘on’ and ‘off’ are fixed selections - the timer willremain in the on or off condition until you next use themanual switch to change the setting.‘auto’ is the normalposition for the switch, allowing control to be governedby the tappet settings - in accordance with‘programming switching times’ above

PROGRAMMING SWITCHING TIMES

Set all tappets between the on and off times required,to the outer edge of the dial (see figure 1). E.g. to set onat 8:00 a.m. - Off at 1:00 p.m. push tappets between dialnumbers 8 and 13 to outer edge of dial. Set any otherrequired switching times in a similar manner.

DOMESTIC HOT WATERPRODUCTION

Domestic hot water production cycle commences oncethe timer has been set and switched on. If boiler andsystem are cold allow 20 - 30 minutes for domestic hotwater heat store to reach working temperature. Centralheating is controlled by setting the time switch - alsolocated on this panel. The boiler control system alwaysgives priority to domestic hot water production byautomatically overriding the central heating mode asnecessary. The interruption to central heating lasts onlyas long as the demand for hot water continues.This hasno significant effect on the heating circuit. Once hotwater demand has ceased the boiler will automaticallyreturn to central heating mode if there is a demand.When hot water only is required turn central heatingtimer switch to ‘off’.

If alternative programmer is used then refer to separateprogrammer instructions.

BY REQUEST COMBI C BOILERS ARE AVAILABLEWITH BUILT-IN TIMERS.

DOMESTIC HOT WATEROPERATION

Hot water is available on demand by turning on a hottap. This activates the sensor which powers thedomestic hot water pump ensuring that all boiler hotwater is diverted to the domestic heat exchanger whichheats the incoming mains water to give instant mainspressure hot water.

Hot water is then mixed with mains cold water by athermostatic mixing valve set to ensure that it does notexceed 65°C. This is shown in accompanyingphotograph below.

The burner may continue to run after hot water draw offhas ceased - to ensure the pre-set temperature isrestored in the heat store. This may also occur at anytime if the control system senses that there is a need toreplenish the heat store, i.e. if there has been naturaltemperature drop in heat store during long periods oflow demand for domestic hot water.

INTRODUCTION TO COMBIOPERATIONS

FIREBIRD COMBI CThe Firebird Combi C is designed to give separatecontrol to both the domestic hot water and to thecentral heating. The Combi C has three thermistorsconnected to a PCB board that gives very accurate andfast temperature control and one high limitthermostats that help to achieve this.

Tank thermistorThe Tank Thermistor controls the temperature of theheat store (or Slave Tank). The Tank Thermistorsensor is located in stat pocket in the top of the tank atthe side of the boiler. When the thermistor senses thatthe heat store is seeking heat it activates a relay on thePCB. board in the control panel this in turn sendspower to the domestic circulating pump and burner.The Flow sensor is the only other device that willactivates the relay in this way when it detects the flowof water on opening a tap. This heat store is a tankwith a bank of water stored at a higher temperaturethan that normally used on a central heating circuit,and is used for domestic hot water production. Thetemperature of this heat store has priority over centralheating. Central heating will not work until the heatstore reaches a temperature of 78˚C. + -3˚C

The Boiler Control thermistor The boiler Control thermistor has a number offunctions.

1. It controlling the temperature of the water in theboiler when in central heating mode (60˚C to 80˚C).When the central heating is on it does not effect thetemperature in the heat store. The check valve on thedomestic flow circuit prevents any circulation to orfrom the heat store. The sensor from this thermistor issituated in stat pocket in the boiler.

2. The over heat function activates the domesticcirculating pump when due to residual heat rise in theboiler, the temperature reaches 93˚C. The water iscirculated from the boiler into the heat store tank thuspreventing the boiler from activating the high limitthermistor.

3. The early alert function controls the burner whenthe Combi is operating in domestic hot water mode. Ifthe temperature in the boiler reaches 87˚C before thetank thermostat cuts out, the early alert thermistorcuts off the burner.


9

HOUSEHOLDER

The High Limit ThermostatThe High limit thermostat cuts off power supply to theburner should all thermostats fail. It is a manual re-setthermostat, and will stay off until such time that it is reset. If this thermostat is activated, the reason foractivating must be resolved before re setting. The sen-sor from this thermostat is situated in stat pocket inthe boiler in the same Thermostat pocket as the boil-er control thermistor. The re-set button is located atthe back of the control panel directly behind thelocation for the optional DWH timer. See ControlPanel Diagram - on page 26.

Flow Switch thermistorThe flow switch thermistor is coloured red and ispositioned in a pocket on the cold feed pipe to theplate heat exchanger. When the thermistor sensesdetects the flow of water on opening a tap it activatesa relay on the PCB. board, this in turn sends power tothe domestic circulating pump and burner.

ImportantKeep thermistor sensor wires separate from mainspower cables. i.e.: Mains feed cable to combi andcirculating pump cables.

A qualified electrician must carry out all electric wiring in accordance with current I.E.E Regulations and any local regulationswhich may apply.

The mains electrical supply must be taken from a double pole isolating switch with a 5amp fuse, positioned somewhere closeto the boiler. Heat resisting cable must be used which can be routed into the boiler through the access provided on eitherside of the base. Ancillary controls may be provided for with terminal connections in the control panel.

3.3 - DOMESTIC HEATING & HOT WATER

When the system is cold and filled to initial fill pressurePi the pointer on the pressure gauge should point at 1bar.The pressure gauge shown has two red zones markedon it. The first is between 0 and 1/2 a Bar. If the pointerfalls into this zone when system and boiler are cold thisis indicating that initial System Fill Pressure hasdropped and this will activate the pressure switchcutting off power supply to the Combi C. Refill systemmanually until indicated pressure rises to 1 bar.

N.B. Insufficient pressure in the boiler will causepower supply to switch off.

* A 12 litre expansion vessel is fitted to boiler,precharged with air or nitrogen to 1 bar which allowsa system static head of 5 metres. If the static head isgreater than this then the air charge in the vessel mustbe increased to balance the higher static head. The aircharge should not exceed a pressure of 1.5 bar.

The Firebird Combi C Boiler’s with built inExpansion Vessels having an initial air chargepressure of 1 bar. If total water content of system isgreater than the capabilities of the vessel suppliedthen an additional vessel will be required to befitted to the return pipe as close as is practical tothe boiler. There should be no valves or restrictionsbetween vessel and boiler. See page 22 for vesselsizes.

If static head is altered then it is also necessary to alterair charge pressure to equal static head (+ 0.3 Bar).Thisis necessary in order to keep system water fromentering expansion vessel until system is being heatedand thus allow its maximum acceptance volume (V) tobe used only to accommodate the expansion ofsystem water during boiler operation.

Remember that air charge pressure must be equal inboth vessels (attached to the same system). In theabove example this is 1 bar. Air charge pressure is theair pressure in expansion vessel before system is filled.It is measured with a tyre gauge attached to Schradervalve on the vessel.

SEALED HEATING CIRCUIT(also applies to System Boilers)

The system must comply with BS 7074 Part 1 and BS5449 Part 1 with a maximum water temperature of80˚C.

* A manual reset overheat limit thermostat is locatedat the rear of the electrical control panel (See Page26, Control Panel Diagram). If a boiler overheatcondition arises the burner will stop and remaininoperative until this thermostat reset button isdepressed.

* A pressure relief valve to BS 6759 operating at 3 bar(45 lb/in2) is fitted. A discharge pipe of 15 mmdiameter is also fitted to the discharge connectionon the pressure relief valve. During installation anextension pipe should be fitted to this, leading, tooutside the building. The pipe should be as short aspossible and may need a tundish fitted in aprotected position within the building.

Note:- Water must not discharge above anentrance, window or where public have access.The installer must be aware that the dischargemay be boiling water.

* A drain cock must be fitted at the lowest points inthe system to enable draining as necessary. A draincock is already fitted at the bottom of the boiler heatstore to enable draining of boiler and tank unit only.All pipes connected to boiler should have shut offvalves fitted to facilitate this.

* A Pressure gauge, having range 0 to 4 bar is fitted toboiler control panel. This indicates water pressure inboiler and system at time of reading. Pressurewhen cold should be 1/2 bar minimum to 1.5 barmaximum. This is known as Initial System DesignPressure (Pi).

N.B. Initial System Design Pressure (measured inbar) equals static head of system (measured in bar)plus 0.3.


22


N.B. The second red zone is between 21/2 and 4 barpressure. When the heating system is up to fullworking temperature, if the pointer on thepressure gauge should enter this red zoneshowing a final system design pressure of morethan 21/2 bar, it is likely that:

(a) Total system water content is greater thanthat calculated and if additional expansionvessel has been fitted it should be replacedwith a larger unitOR if integral boiler expansion vessel only isused then an additional expansion vessel isrequired.

(b) Static head may be higher than calculated. Inthis case it is necessary to re-measure statichead and revise expansion vessel air chargepressure.

(C) Expansion vessel incorrect size or air chargepressure incorrect.

Refer to BS 7074Part 1 and BS 5449 for further information.

EXAMPLE: using above table

If total water content of system is - 150 litres

and initial system pressure required is - 1.0 bar

then vessel volume required is - 16.3 litres[from above table]

The vessel supplied with boiler is - 12.0 litres

therefore an additional vessel of - 4.3 litresis required (minimum)

(For this system of 150 litres - total water volume)

..Nearest available stock size for additional vesselrequired, at 1 bar initial system pressure (taken fromabove table) is 5 Litres.

It is emphasised that the installer should be fullyacquainted with sealed system installation andoperation, calculation of total system water volume,determining of initial system pressure required andcalculation of any additional expansion vessel volumerequired. Warranty is void when the boiler isinstalled in a system with insufficient expansions.

NB .. Ensue that all expansion vessels in the samesystem are set at EQUAL air charge pressures.

EXPANSION VESSEL AND SYSTEMREQUIREMENTS

DOMESTIC HOT WATER CIRCUITS

The final 600 mm mains water supply should be ofcopper tube to BS 2871 Part 1. Ensure that any capillaryfittings used are of lead free solder variety.

For user comfort the mains pressure at taps shouldbe between I and 5 bar. If it exceeds this it isadvisable to fit a pressure reducing valve adjustedto reduce pressure to an acceptable level withinabove range.

To ensure user comfort and satisfaction it may beadvisable to discuss foregoing with householder.Wherelong hot water supply-pipe runs are used these shouldbe insulated to prevent rapid cooling of residual hotwater after draw off is completed.

If the boiler is fitted in a hard water area check thathardness does not exceed 150 p.p.m. by testing with astandard test strip. Immerse test strip in flowing tapwater for one second. Shake off excess water. Checkstrip after approximately fifteen seconds. If three ormore zones have changed colour the water hardness isover 150 p.p.m. (Read instructions on test strippackage). Fitting of an in line scale inhibitor is thennecessary.

Failure to check water hardness and fit appropriatewater softening equipment will result in scale buildup and consequent reduction in water heatingperformance. Check with local Water Authority if indoubt.

23


Hot and Cold taps, mixing valves and fittings must besuitable for operating at mains pressure up to 10 barBidets with the supply of hot and cold mains water arepermitted if they are of the over-rim flushing type andhave shrouded outlets which enable them to havetemporary hand held spray attached. Showers of looseheaded or flexible type must be fixed so that the headcannot fall closer than 25mm above the top edge of thebath to prevent it immersing into the bath water.Alternatively the shower should have a double checkvalve incorporated at the point of the flexibleconnections.

WATER FLOW REGULATION

The flow rate of water from individual taps may beaffected by any of the following:-

1. Number of taps in use at one time2. Cold mains pressure3. Diameter and length of pipework in the

domestic water circuits within the dwelling.4. Excessive flow from 3/4” bath taps in a house

system converted to mains water supply.

It is recommended:-A. To ensure that the mains water connection to

the appliance is the first connection fromthe mains on entering the dwelling.

B. Where flow starvation is encountered that flowrestrictors or balancing valves are fittedat supply outlets.

* The boiler has circulating pumps fitted therefore noother is normally required. They are factory set atmaximum output.This setting should not be alteredon the domestic hot water pump as production ofdomestic hot water may be adversely affected.

SYSTEM FILLING, TESTING AND MAKE-UP

IntroductionMains cold water is supplied through the boilerpipework to two separate circuits operating at differentpressures.

Circuit OneThis is the Radiator Heating System including boilerand primary tank which is filled from mains supply viaflex filling loop (see - Method A) within boiler to apressure determined from system static head,expansion vessel size and system water volume. Thisflexible filling loop should be disconnected whenboiler and system are filled and checked, Seediagrams - Method A & Method B).

Circuit TwoThis is the domestic cold water supply through theboiler plate heat exchanger via domestic hot waterpipework direct to hot taps. This works at full mainspressure or if this is excessive at a reduced pressurecontrolled by a mains pressure reducing valve to apressure acceptable to householder and satisfactory forthe correct operation of Combi C Boiler System.Thismains pressure reducing valve is not supplied withboiler, but will be available from a local supplymerchant.

System filling should take place slowly and canbe done by either of the following methods:-

Manual FillingThe Firebird Combi C comes with this system built intothe appliance. It consists of a flexible hose connectionwith a butterfly shut off valve at each end and a doublecheck valve assembly at boiler end. To conform torequirements of BS 7074 Part I and local water AuthorityBye Laws, the flexible hose should be disconnected atone end when filling has been completed and checked.Two end caps are supplied and should be fitted todisconnected ends as a safety precaution againstinadvertent opening of ball valves.

Pressure gauge on Control Panel should be checkedoccasionally when system is cold. Refill to initial fillpressure if necessary. Should this be a frequentoccurrence, complete system should be checked forleaks.

Automatic FillingAutomatic System filling may be made with a feed andmake-up cistern connected through a double checkvalve and stop valve assembly to the return side of theheating system as close to the boiler as is practical. Thiscistern should be located above the heating systemshighest point to give a minimum static head of 300 mmbetween it (highest point) and cistern. The manualfilling system fitted to boiler should then bedisconnected and connection points blanked off.

This system has the advantage of automatic watermake-up in the event of system pressure loss due to airelimination and minor leaks. In any case control panelpressure gauge should be occasionally checked.

N.B. Remember also to check air fill pressure ofExpansion Vessel when system is coldusing standard tyre gauge connected toSchrader air valve on vessel.

NOTE: There shall be no direct connection to themains, even with the use of a non-returnvalve without the permission of LocalWater Authority.

* It is recommended that an inhibitor be addedat the time of final fill to protect the Systemfrom corrosion. Ensure that this is carried outin accordance with inhibitor manufacturersinstructions. Installer should ensure thatinhibitor used is suitable and that it will haveno adverse effect on Expansion Vesselsdiaphragms or any other part or componentof the system.

COMMISSIONING

* Before proceeding to filling, ensure that electric-ity supply is switched off at mains to avoid anypossibility of time switch operating and passingpower to appliance prior to filling.

Filling and Testing

Check that all connections, especially compressionjoints, are fully tightened. Re-check and ensure thatpressure vessel air charge is correct, then fill systemwith water via filling system used. Turn off watersupply before system pressure reaches safety valveoperation point of 3 bar. (Say 2 to 2.5 bar).Vent systemvia all manual air vents including circulating pumps,boiler, radiators, system high points. etc. Check that dustcaps are loosened on auto air vents, keep constantcheck on system pressure gauge (fitted to controlpanel). If pressure has dropped re-admit water to abovepressure. Ensure all appropriate boiler and systemvalves are open.

METHOD BWith water supply turned off, thoroughly flush outboiler and system to remove all foreign matter beforeallowing boiler and pumps to operate. If in doubt drainsystem and repeat above procedure. At this stageflushing-out water should be clean and clear of allforeign matter.

Refill the system and again vent at all points asdescribed above. Examine the complete system forwater leaks having pressurised it to 1 - 2.5 bar. Correctany leaks, then check operation of safety valve byadmitting further water until this valve operates. Thisshould occur when system pressure rises to between2.7 and 3.3 bar.When satisfied with valve operation, andwith mains water still turned off, draw off sufficientwater until initial system design fill pressure (Pi). (cold

fill) is established (0.5 - 1 bar - as calculated for system).

Remember that initial cold fill pressure can only bechecked when system water has properly cooled down.Check that final operating pressure (Pf) is under 2.5

bar with all radiators turned on and up to highestworking temperature. Should system operatingpressure exceed this, check:

1. That initial cold fill pressure is correct and , ifadditional expansion vessel is fitted, thatpressure is equal in each vessel.

2. That expansion vessels are sized correctly.

Special attention should be given to existingheating systems where Firebird Combi C boiler hasreplaced an existing unit. Extra effort should bemade to ensure that all original pipe work andradiators are repeatedly flushed. If possible use aproprietary cleansing agent suitable for system asloosened scale and foreign matter can seriouslyreduce domestic hot water performance and pumpefficiency.

Use corrosion inhibitor of suitable type.

PRE- INSTALLATION CHECKS

The installer should also be aware of his/herresponsibilities under The Health and Safety at WorkAct. The interests of safety are best served if the boileris installed and commissioned by a competentengineer, OFTEC trained and Registered. If not aBuilding Notice is required in England & Wales. Otherparts of the British Isles including the Channel Islandsalso require notification to building control.

BOILER INSTALLATION:Other than special considerations for condensateremoval and plume dispersal, the installation of oilfiring condensing boilers is the same as fornon-condensing boilers.

BS 5410 : Part 1 1997 gives the requirements fordomestic boiler and oil storage installations.

For condensing boilers the same requirements applyfor installation with regard to cleaning and flushingand providing inhibitors as are followed for any otherboiler. Manufacturers instructions must always befollowed together with the requirements of BSEN12828, 2003 & BS EN 12831, 2003, which supersede BS5449 1990, and the statutory requirements of theBuilding Regulations.

STANDARDS & REGULATIONS

To ensure the highest standards of installation &safety, it is important that the boiler be installed incompliance with the following regulations whereapplicable. It is the responsibility of installer andeveryone concerned with any aspect of installationto ensure that all applicable standards andregulations are fully adhered to.

6.1 - INSTALLATION GUIDELINES

The safety high limit thermostat [2] will shut off the boilerand will require the limit button to be pushed to restartthe boiler. If the problem re-occurs, you should call yourservice engineer.

In cases where the flow from the boiler is down to theheating system, fitting a PUMP OVER RUN THERMOSTAT [3](A Pipe Stat) is recommended. This is to prevent theresidual heat build up in the boiler from unnecessarilyactivating the high limit thermostat and thus causingnuisance. See Heat Pac Wiring Diagram in InstallationInstructions on page 34.

We have factory fitted pump overrun thermostats onKitchen,System, Combi and Heatpac range of boilers.

TIME AND TEMPERATURE CONTROLSThe Building Regulations state that central heatingsystems must have time and temperature control on thepipe circuits (eg thermostatic radiator valves / TRVs, roomthermostats, cylinder thermostats etc.).

BURNERThe burner is factory set for use with kerosene28 second class C fuel.

ROOM SEALED BALANCED FLUES.(a) BS5410 – 1997 Code of practice for oil firing.Installations up to 45 kW output capacity for spaceheating and hot water supply purposes

Paragraph 11.2 Mounting

“The flue terminal should be mounted so that it isseparated from any combustible material forming a part ofthe building.

Such combustible material may take the form of claddingon the surface of a non-combustible wall through whichthe flue outlet passes. In such a case, the claddingadjacent to the flue outlet should be replaced bynon-combustible material extending not less than 50mmbeyond the outside dimensions of the flue outlet.

The wall through which the flue outlet passes may itself beof combustible material, and if so the flue outlet, where itpasses through the wall, should be surrounded bynon-combustible insulating material not less than 50mmthick. The insulating material itself should be contained ina steel liner to provide the necessary structural rigidity andto prevent moisture reaching the insulating material.”

Please not following important points beforecommencing installation. Failure to do so willinvalidate warranty

INSTALLATION & COMMISSIONING:Boilers must be installed, commissioned and serviced byqualified and experienced persons and as set out in theinstallation manual, using correct test equipment.

EXPANSION VESSEL:Total water content of system and boiler must becalculated to determine if an additional pressure vessel isrequired.

HARD WATER - LIMESCALE:Failure to check water hardness and fit appropriate watersoftening equipment will result in scale build up andconsequent reduction in water heating performance.Check with local Water Authority if in doubt.

PLASTIC PIPING - WARNINGThe boiler thermostat control and safety system is notdesigned, and must not be relied on, to protect plasticpipe from overheating. Plastic pipe must never beconnected directly to the boiler. If you choose to useplastic pipe anywhere on your heating circuits, thenplease consult the plastic pipe manufacturer for theirinstructions on how to ensure their product neveroverheats. Our boiler control and safety high limitthermostats are not designed to fulfil this function. (Theymay suggest the fitting of independent pipe thermostats,or thermostatic mixing valves linking flow and return). • Firebird accepts no responsibility for failure of plasticpiping and fittings for what ever reason.

WARNING:The manufacturer cannot accept responsibility for anydamage to persons, animals or property due to error ininstallation or in the burner adjustment or due toimproper or unreasonable use or non observance of thetechnical instruction enclosed with the burner, or due tothe intervention of unqualified personnel.

BOILER THERMOSTAT / THERMISTOR FUNCTIONThe CONTROL THERMOSTAT [1] on the boiler allows thehouseholder to vary the water flow temperature from alow of 60˚C to a high of 80˚C to 82˚C, depending on themodel.

In accordance with EU boiler standards, your boiler is alsofitted with a SAFETY HIGH LIMIT THERMOSTAT [2], fixed at114˚C. This system protects the boiler in the event of thecontrol thermostat failing and keeps the boiler safe.

6.2 - POSITIONING THE BOILER

Ensure that adequate clearance is available for making the water and flue connections.

As the boiler is serviced from the front, no headroom clearance is necessary but aclearance of 750mm must be available at the front of the boiler.

No special hearth is required as the boiler is fully insulated, but the floor must belevel and capable of supporting the weight of the boiler and its water content.

Sound levels must also be a consideration. Whilst Firebird Enviromax boilers are one of the quietest boilers onthe market, some householders are particularly sensitive and the following points should be considered:

1. Tiled surfaces in a small room will amplify noise - particularly if the wall construction is hollow.

2. If a conventional flue passes through a bedroom it is capable of transmitting noise.

3. Low level balanced flue terminals can produce exhaust noise on the outside terminaland this should be considered when siting near adjacent property.

4. The Firebird Balanced Flue Kit has been specifically designed for Firebird’s indoor boilers.The use of third party low level flue kits is not recommended and will affect its warranty.

5. The Siting of the boiler should take into account the disposal of condensate products.

• It is recommended that a suitable corrosion inhibitor is added to the heating system.

• New and existing systems should be treated with chemical cleaner and properly flushed beforethe boiler is fitted and corrosion inhibitor added.

• In areas of hard water a suitable descaler would also be required.

CONDENSATE DISPOSAL

SYSTEM NO. 1 - CONDENSATE PUMPIMPORTANT

Firebird condensing boilers when in condensing mode extract more heat from the flue products and the resultingcondensate which is mildly acidic needs to be drained from the boiler via a condensate pipe to the drainage system.

Provision must be made for the removal of condensate from the boiler to a internal soil stack, waste pipe,external soil stack, gully or soak-away as per BS6798.

The 75mm trap is provided with the boiler and situated on the front of the boiler (below the pressure vessel where fitted)as per figure 1. This should be checked at regular intervals and cleaned at annual service.

The condensate line should be plastic and minimum diameter of 22mm.

Copper or steel cannot be used.

A fall from the boiler of 1:40 minimum.

As few bends as possible to reduce the risk of trapping condensate.

Condensate pipework that is external or in an unheated garage should not exceed 3 meters and lagged with water proofinsulation to prevent freezing.

These notes form an integral part of the information shown above.

1. Terminals should be positioned so as to avoid products of combustion accumulating in stagnant pockets around the building or entering into buildings.

2. Appliances burning Class D oil have additional restrictions.(See 1.7.3 in Oftec Book 3 - Aug. 2002)

3 Vertical structure in N, 0 and P include tank or lift rooms, parapets, dormers etc.

4. Terminating positions A to L are only permitted for appliances that have been approved for low level flue discharge when tested to OFS A100 or A101.

5. Terminating positions must be at least 1.8 metres distant from an oil storage tank unless a wall with at least 30 mins fire resistance and extending 300mm higher and wider than the tank is provided between the tank and the terminating position.

6. Where a flue is terminated less than 600mm away from a projection above it and the projection consistsof plastic or has a combustible or painted surface, then a heat shield of at least 750mm wide should befitted to protect these surfaces.

7. For terminals used with vapourising burners, a horizontal distance of at least 2300mm is required between the terminal and the roof line.

8. If the lowest part of the terminal is less than 2 metres above the ground, balcony, flat roof or other place to which any person has access, the terminal must be protected by a guard.

9. Notwithstanding the dimensions given in the drawing and table, a terminal should not be sited closerthan 300mm to combustible material.

BALANCED FLUE BOILERS

The Firebird boiler may be set for Room-sealed balanced flue operation using a Firebird condensingbalanced flue kit. This kit does not draw combustion air from inside the room. It is drawn fromoutside direct to burner by airpipe supplied with boiler. Flue gases are expelled through the samekit. However, if the boiler is installed in a compartment or small room, some ventilation air isnecessary to maintain acceptable temperature in boiler area.

Use of any equipment other then the matching Firebird low level roomsealedconcentric flue kit is not guaranteed for low level discharge and will probably

invalidate the warranty.

Balanced flue boiler in room (eg. kitchen) does not require individual ventilation.� �

Ventilation and Combustion Air

Conventional Flue BoilersAn adequate supply of combustion and ventilation air is essential for efficient and safe boileroperation and the openings for this should be positioned to cause least possible draught, with nopossibility of being accidentally blocked.

Please note: The British Standard Code of Practice for Oil Firing BS5410: Part 1, requires a permanent airinlet opening of 550mm2 per kW (above 5 kW) of boiler rated output. (Note: 1kW = 3412 Btu/h).

Also, when the boiler is installed in a compartment or confined space, ventilation openings arerequired to ventilate and to avoid overheating in the boiler area.

FULL TEXT of both BS 5410 Part 1: 1997 and appropriate BuildingRegulations for each country should be obtained and fully applied

N.B. Please Carefully Note:A. For boiler installations in domestic garages in Scotland, Part F of Building Regulations permits only

Room Sealed appliances to be used (Ref. OFTEC Bk. Three May 1999 page 1 (18).

B. Technical annex T1/127 to OFTEC Book Three, May 1999 page 2 (19) Para. 1, 2 states “In Scotland andthe Republic of Ireland only Room Sealed Balanced Flue Appliances can be used in that location”(i.e. domestic garages).

DefinitionsCombustion Air : Air required directly by boiler oil burner for combustion process.Ventilation Air : Air required in room for ventilation, cooling, etc. and to promote a healthy living

environment.

CONDENSATE PLUME DISPERSALWhen choosing the location for a condensing boiler,special consideration must be given to the positioning ofthe flue terminal. Care should be taken to locate it so as toprevent either the end user or their neighbours perceivingthe plume to be a nuisance.

It should be noted that the normal statutory clearancesrequired around low level flue terminals (ref. T45T1/135)may not be sufficient to cope with plume dispersalfrom a condensing boiler. The following points should beconsidered: -

1. Plumes can extend out horizontally and can also driftout to the sides and above the terminal. Care needs tobe taken, therefore, to avoid the plume reachingadjacent surfaces, particularly windows andneighbours dwellings.

2. Flue terminals need to be located where air can passfreely across them to disperse vapours.

3. The effect of the moisture generated must beconsidered in relation to the possible corrosion ofmetal parts it might reach and to the possibleformation of ice on pathways in freezing conditions.

4. Keep flue terminals a minimum of 1 m (horizontally)from openings in the building.

5. Do not install flue terminals directly below a window.

6. Do not install flue terminals next to a door.

7. Do not install flue terminals within 1 m of ventilatedsoffits or eaves.

8. Keep flue terminals at least 1 m away from a surface orboundary facing the terminal.

9. Follow the appliance manufactures instructions.

IMPORTANTThe Firebird condensing boiler must not be installedwith existing flue systems. A flue system suitable for wetflues must be used. If a flue system which is unsuitableis used it will invalidate the warranty.

Because of the high operating efficiencies of theFirebird condensing boilers and low flue gastemperatures, it is necessary to pay extra specialattention to the flues and chimneys.

Existing chimneys must be lined with a liner certified assuitable for condensing oil boilers by flue manufacturer.

Twin wall insulation must be used for externalapplications, with seals and stainless steel inner skin.

Only vitreous enamel or high grade stainless steel canbe used between boiler and chimney in an internalinstallation, aluminium or asbestos type material mustnot be used (Vitreous enamel must not be cut).

Condensate must be able to run back into the fluechamber of the boiler and not escape, as up to 1.5 ltr. ofcondensate can be produced in a conventional flue. Notrap is required in the flue system.

The terminal must be positioned to avoid combustionproducts entering the building and as per BuildingRegulations. Refer to BS5410:1 OFTEC installationrequirements books one and two.

OIL STORAGE TANK SITING

Consult OFTEC Manuals

It is very unlikely that a fire should start from a domes-tic oil tank, however it does need to be protected froma fire which may originate in a building nearby. For thisreason, the tank should be located at least 1.8 metresfrom any building and no closer than 760mm from anyboundary. If it must be closer than 1.8 metres, the build-ing wall should not have any openings other than ven-tilation openings. In addition, the wall should have atleast 30 minutes fire resistance and extending 300mmhigher and extends 300mm beyond both ends of thetank is provided between the tank and the terminatingposition and the wall should have a half hour resistanceto an internal fire and extend 1.8 metres from any partof the tank.

A non-combustible radiation barrier is analternative but this must meet the requirementsof BS 5410 Part 1: 1997,“clause 28” Section 6.4.

Steel tanks must be mounted on brick or blockpiers with a waterproof membrane between thepiers and tank.

See Oftec Technical Information T19

Oil storage tanks should not be sitedwithin 1.8m of boiler flue outlets.

Do not allow household waste or hot ashescontainer in vicinity of oil storage tank orboiler flue outlet.

FLEXIBLE OIL PIPE(S)

A flexible burner oil hose is supplied with the boilerwhich must be wholly contained with in the appliancecase.

Please note: A filter must not be fitted inside theboiler and all joints in the oil line MUST BEOIL-TIGHT. Soldered joints are not permissible.Before connecting to the boiler always flush thecomplete oil supply line and ensure that oil supply iscompletely clean and free of any dirt or foreignmatter.

SINGLE PIPE SYSTEM

Where installations have the bottom of the tank abovethe oil burner, a single pipe system may be used.The oilburner should then be set for single pipe operation -See also manufacturers oil burner manual

�

TWO PIPE SYSTEMS

Where installations have the bottom of the tank belowthe oil burner pump a two pipe system is required.Ensure that valves and filters are not fitted in the returnline as this must be unobstructed at all times.

The oil burner pump should be set for two pipeoperation as detailed in accompanying oil burnermanufacturers manual, refer also to page 14 of thismanual.

TIGERLOOP SINGLE PIPE SYSTEMS

IMPORTANT:The Tigerloop should not be fitted inside the

dwelling - See TI/139 drawing below and OFTECmanual book 3 page 2(8:1)

Where installations normally require a two pipe systembut have long or impractical return line runs, a‘Tigerloop’ De-aerator can be used which removes airfrom a single - pipe - lift oil feed. Higher lift heights canbe achieved than are possible with conventional twopipe systems.

The oil burner pump should be set fortwo pipe operation.

REGULATIONS & STANDARDSIn England and Wales, installation in single familydwellings have to comply with the building RegulationsPart J. This requires compliance with BS 5410 : Part 1 :1997. All tanks either deemed to be at risk or with acapacity of more than 2,500 litres will require to bebunded.

For installation in Scotland, Building Standard Part Fapplies. This requires compliance with BS 5410 : Parts 1and 2. All tanks either deemed to be at risk or with acapacity of more than 2,500 litres will require to bebunded.

Those externally installed tanks with a capacity of lessthan 2,500 litres will require a bund if located not morethan 50 metres from a spring or bore hole, 10 metresfrom controlled waters and additionally where it mayconstitute a hazard.

The above risks and hazards are described in OFTECTechnical Information Note TI/133.

In Northern Ireland, the Building Regulations do notcurrently cover the installation of oil storage tanks.

In the Republic of Ireland the requirements of BS 5410:Parts 1 and 2 are required to be complied with beBuilding Regulations Part J.

FIRE VALVES

A fire valve is an essential part of the oil supply system.It should be capable of cutting off the flow of oiloutside the building in the event of a fire starting upwithin the boiler. The valve should be located justoutside the building at the point where the oil supplyline enters. It must be activated by a remote sensorlocated over the burner, but in a position clear of anydirect radiation or excessive heat.

IMPORTANT: Fire Valves should comply with OFTEC Standards OFS E101Fitting of Fire Valves shouldcomply with BS : 5410 Part 1

WARNING• SINGLE PIPE The pump is designed to allow working with one pipe.

• TWO PIPE In order to obtain two pipe working it is necessary to unscrew the

return plug (2), screw in the by-pass screw (3) and then screw in return oil line (2). (See fig. 4).

In the two pipe systems, before starting the burner make sure that the return pipe-line is not clogged. An excessive back pressure would cause the damage of the pump seal.

HYDRAULIC SYSTEM

1 - Suction pipe2 - Return line3 - By-pass screw (* is supplied loose in burner pack )

4 - Pressure gauge connection & Bleed screw5 - Pressure adjuster6 - Vacuum gauge connection7 - Valve8 - Auxiliary pressure test point

H = difference of level L = Max. length of the suction lineI.D. = Interminal diameter of the oil pipes

PRIMING PUMP:On the system in fig. 5 it is sufficient to loosen the suction gaugeconnection (6, fig. 4) and wait until oil flows out.On the systems in fig. 6 and 7 start the burner and wait for the priming. Should lock-out occur pr ior to the arr ival of the fuel, await at least 20 seconds before repeating the operation . The pump suction should not exceed a maximum of 0,4 bar (30 cm Hg). Beyond this limit gas is released from the oil. Oil pipes must be completely tight.In the vacuum systems (fig. 7) the return line should terminate within the oil tank at the same level as the suction line. In this case a non-return valve is not required. Should however the return line arrive over the fuel level, a non-return va lve i s required. This so lut ion however i s less sa fe than previous one, due to the possibility of leakage of the valve.

COMMISSIONING

It is recommended that commissioning is carried out bya competent and qualified service engineer.

It should be noted that it is the responsibility of theinstaller to ensure that the boiler is properlycommissioned. Failure to do so may invalidate theboiler guarantee and any extended warranty.

PROCEDURES

1. OIL TANK

The installation of the oil tank and supply line shouldcomply with all the instructions shown earlier in thismanual. Consult OFTEC Manual - Book No. 3, Section 2.

If a single supply line is used ensure that the bottom ofthe tank is above the burner. A suction line system via ade-aerator should be used where the level of the oil inthe tank may fall below the level of the oil burner pump.

CHECK AND ENSURE CORRECT GRADE FUEL OIL HASBEEN SUPPLIED.

2. THE BURNER

A two single pipe system may also be used in low-leveltank installations. See page 21 Section 5. Please flushout oil pipe by drawing off some oil before connectingfuel pipe to burner - otherwise there is a danger of gritand dirt being forced into the burner pump, resulting inpump blockage, damage and ‘lock-out’

3. THE BOILER

A. Switch off the power supply, ensure that theboiler and system is full of water, all valves areopen and that installation conforms with allStandards, Regulations and Instructions.

B. Depending on condensate disposal systemcheck that the condensate trap is primed orpump is operational.

C. Check that boiler baffles are correctlypositioned.

D. Check the oil supply by disconnecting the oilsupply hose at the burner and running off aquantity to ensure it is free from air. then bleedair from burner pump. Refer to section 7, page56, sketch Fig. 5.

ATTENTION

It is the responsibility ofINSTALLER / HOUSEHOLDER

to ensure that the boiler isPROPERLY COMMISSIONED

by a competent or OFTECregistered engineer.

Failure to have the appliancecommissioned and warranty card

completed and returned mayinvalidate the warranty.

It is not the responsibility of theManufacturer or the Supplier if aboiler will not operate properlydue to non commissioning of the

appliance.

PLEASE NOTE:Should a site inspection be

required from the manufacturersengineer, a call-out fee

will be charged if the faultis a result of incomplete orincorrect commissioning.
