ControlControl of air and fuel is performed ac-cording to the fuel type, burner size andrequirement:

• Two and three stageThe oil part of the dual fuel burner has a nozzle head with two or three nozzles. The capacity regulation is achieved by opening or closing the oil solenoid valves 2 and 3 with corres-ponding changes in air amount.

• Sliding two stageOn sliding two stage regulation, the low fire and high fire points are as-signed within the control range. The burner slides depending on heat requirement between both operating points. There is no sudden increase or decrease of supplied fuel amount.

• ModulatingModulating burners operate according to the heat requirement at any operat-ing point within the control range.

Reduced starting capacityThe burner starts at ignition position viaseparated pilot line. This way only asmall amount of gas flows into the com-bustion chamber. After a certain delaytime the burner operates in low fire.

Controlled shutdown from low fireControlled shutdown of the burner isperformed only at low fire. Sudden pres-sure surge in the gas supply line can beavoided.

Gas trainAs standard, Weishaupt gas and dualfuel burners are always equipped withtwo main gas valves.Gas train can be built according to mostapplicable North American codes andstandards.

Digital combustion managerW-FM100 and W-FM200 combustionmanager control all essential burnerfunctions, e.g. fuel and air supply andmonitor the flame with digital precision.The target is optimization of operatingconditions, maximization of economicalaspect and minimizing the emissions.Thanks to the digital combustion tech-nology, such optimization is availabletoday at reasonable cost. Expenses forinstallation and maintenance are evenclearly lower than with conventionaltechnologies. For example, a separateremote panel is no longer required forburner control. Furthermore, remoteoperation, remote diagnostic and remotemonitoring of the appliances are nowrealizable. This increases the safety andcomfort for operator.

ApplicationsThe burners can be used with heatexchanger such as heating boiler, steamboiler, air heater and for certain processapplications. Due to the fact that theburner is capable of overcoming highcombustion chamber pressure, they aremost compatible with modern high per-formance boilers.

FuelsOil sectionLight oil (#2 oil), viscosity 6mm2/s at68F (20°C)

Gas sectionNatural gasPropane (LPG)

Installation locationThe burners are designed for indooroperation with temperature of 5F(–15°C) up to 100F (+40°C) and rela-tive humidity of max. 80%

CertificationThe burners are in compliance with mostapplicable European and NorthAmerican standards

The advantages of digital combustion management

Digital combustion managementmeans optimum combustion figures,continuous repeatability of settingvalues and ease of use.

Weishaupt burners are equipped withelectronic ratio controller and digitalcombustion management to satisfy therequirements of modern combustiontechnology, which demand a precise andcontinuously reproducible supply of fueland combustion air. Only in this wayoptimal combustion figures can beensured over extended periods of time.

If required, the burners can also beequipped with O2 trim* and variablespeed control.

Error free operation via AZL displayand control unitSetting and control of the burner func-tions is achieved using a control and dis-play unit, the AZL, which is equippedwith an LCD display. The AZL is con-nected to the combustion manager via asafety bus system and can be posi-tioned anywhere according to the user’spreferences within 325 ft. (100 m) dis-tance from the burner.

Flexible communication possibilitiesThe integrated communication interfaceenables all necessary information andfunctions to be transmitted to a BMSsystem. If required, remote operation andremote diagnosis functions, which areaccessible via modem, can be installed(e.g. oil/gas change-over, adjustment ofsetting values).

Communication with external systemsvia BUSIf data has to be exchanged betweenburners and other heating systems withPLC devices, the information can beaccessible via eBUS or MODBUScommunication system.

* In conjunction with W-FM 200 combustion manager

Integration with building managementFor control and management functions,Weishaupt offers ProGraf NT - asoftware product that provides a realtime solution to meet all requirements.

The price advantage of the newtechnologyWith improved technology and ease ofuse, combustion plant is becoming evenmore economical than ever before.

• No additional burner controls arerequired, since this function is alreadygoverned by the combustion manager.Fuses and burner motor starter are theonly additional items required.

• Less installation work means lesserrors: the burners are tested as acomplete unit at the factory.

• If required, the W-FM 100 is availablewith an integrated modulating con-troller and variable speed module. Noseparate equipment is required. Themodulating controller and variablespeed module are included as stan-dard with the W-FM 200.

• Commissioning and service worktakes less time. The initial presettingof the burner is carried out at the fac-tory. On site, only the site specificoperating points have to be adjusted.

• To facilitate O2 trim, only an O2 probeand O2 module have to be installedand connected with the W-FM 200via the internal safety BUS.

Increased safety via shut offassembly with solenoidvalve

The electromagnetically actuated safetyshut off device isolates the oil supply andreturn on burner models RGL40 to 70when the burner shuts down. Oil shut offdirectly at the nozzle ensures a drip freeburner shut down. (Burner modelRGL30 uses a system without nozzleshut off).

Considerable noisereduction due to soundabsorbing air inlet

By utilizing sound absorbing materials onthe fan suction side it has been possibleto reduce operational noise considerably.

Emission figures for 1LNversion

Excellent emission results are achievabledepending on the geometry of thecombustion chamber, volume load andfiring system (3 pass or reverse flame).

When stating information relating toguaranteed values, certain conditions formeasurement and evaluation must betaken into account, such as combustionchamber loading, test tolerances,temperature, pressure, humidity.

The designation 1LN is used on the newWeishaupt Low NOx burner series.
