Before completing any masonry works, make surethere is enough room for the appliance to operateand for it to be serviced. To proceed correctly, it isimportant to make sure the wall or ceiling to whichthe appliance is to be secured is suitable for sup-porting the weight of the appliance; in this respect,check the anchors provided to make sure they areable to sustain the appliance taking into accountthe material of which the wall or ceiling is made. Ifthey are not, replace them with other more suitableones. Make sure there is no matchboarding or pla-stic inserts which are not heat resistant and whichcould come into contact with the fume extractionpipes.

In case of a wall made of material with low resistanceto heat, an interspace can be made around the fumeexhaust pipe that is insulated with material resistant tohigh temperatures or else a hole can be made with adiameter that is at least 4 cm bigger than that of thefume exhaust pipe.

Installing the appliance in bathrooms/showers or nearwater dispensing units is forbidden. In such cases spe-cial protections must be made that ensure the applianceconforms with "specific" Electrical Safety Standards.

Note*: to prevent directing the air flow to people height, the appliance should be fitted at a MINheight of 2.30 m and a MAX height of 3.00 m to prevent any air stratification.

Installation "against the wall" (crossed by inlet and exhaust pipes)

Before installing, make sure the diameters, the total lengths and the end pieces of the pipes and theiroverall flow resistances do not exceed the prescribed limits as indicated in the chapter on Pipelengths and Pressure loss.

Fitting the guide arms and template:Choose where to position the convector on the ceiling,fit the 2 guide arms, according to the following proce-dure:- using the 4 screws provided, fasten the 2 tie-rods (3),aligning the 2 guide arms (2);- mark the 6 holes for fastening the 2 guide arms (2).Drill the holes using a Ø 9 mm bit if the providedanchors are used. This diameter will be different ifother anchors, considered more suitable, are used.Always remember that the working width of the slot isØ 9 mm;- fasten the guide arms + tie rod structure (2+3) to theceiling so the two arms fasten onto the wall (important:the 2 tie-rods must be fitted in both the ceiling solutionand the bracket solution);- Move the metal template (5) close to the arm (2) (theright one), marking the centre of the inlet and exhaustpipe outlet holes and the template fastening holes.Alongside hole B, make the centring hole using an Ø 8mm bit, fasten the template (5), using 2 Ø 8 mmanchors positioned at holes B and D. Once centring has been made, disconnect the half-cut discfrom the hole on the template (5).Make a hole using a suitable milling unit or by making a series of small holes in the circumference.

IMPORTANT! Detach only the central Ø 65 mm disc for pipes diameter Ø 32 mm and ring Ø 110mm for pipes diameter Ø 54 mm.

Proceed to drill the wall taking into account the details shown on the Table.

Installation "away" from the wall (crossed by air inlet and fume exhaust pipes)Installation is practically the same as that "against the wall". The only difference is that the template(5) has to be positioned without the reference of the guide arm (2). It is best therefore to install theguide arms, position the convector and then fit the template on the wall.Fit the pipes according to lengths and layout and join these to the union on the convector and tem-plate.

Adapting the outlet union to the pipe diameterQuesta operazione si rende necessaria solosui Termoconvettori 40 - 60, qualora si passi,dove è consentito, dalle tubazioni Ø 32 mm aquelle Ø 54 mm e viceversa.The appliance is always supplied by theManufacturer ready to use the Ø 32 mmpipes.This operation must be performed before fit-ting the convector on the guide arms.Proceed as follows:- loosen the screws (2) of the outlet union (1);- remove the inlet/exhaust pipes;- fit the diaphragms (3)(for Ø 32 mm);- fit the pipes back on (be careful to correctlyfit the two "round-offs").- fit the outlet union back on (1).Assembly must be made as shown in the illu-stration.

Fitting parallel "air inlet/fume exhaust" pipesThis solution has been conceived to make air inlet/exhaust directly behind the appliance or awayfrom the appliance using parallel pipes; formax diameters and lengths, see the aboveTable.Adapt the length of the pipes provided tothe actual thickness of the wall Thick. + Xmm, cutting off any excess part.Complete the missing section with the pipesnecessary for "away" installation, remem-bering to fasten and insulate these whennecessary.

The pipes must always be cut perpendicular to the axis of the pipe itself, being very careful not todeform the pipes; after cutting, carefully remove any remaining burrs.

On the pipes featuring seals, the O-rings must not protrude from their seats. For easier fitting, usesilicone or soapy grease.Select the type of combined end-piece fitting: if fitted from inside together with the pipes (1a, 1b,small flange) or that fitted from the outside (2a, 2b, large flange).

Fitting pipes with combined end piece fastened from insideFit the combined end piece (2) on the pipes after cutting them in the required lengths and fasteningthem using the screws provided (1). Make sure the fume exhaust hole of the end piece (a) is positio-ned high up.

If not already done, detach the half-cut disc from the hole on the template and then fit the pipeassembly in the wall, positioning it so the small flange of the combined end piece is flush with theouter wall. Secure the pipes with mortar so they cannot turn, being careful not to dirty them inside.To cover the drilling imperfections on the wall, if the outer end piece is easy to reach, we suggestusing a plastic rosette (3) (4) which can be fastened with silicone or other adhesives for plastic mate-rials.

INSTALLATION WITH SEPARATE PIPES AND SEPARATE END PIECES

To install the convector on the ceiling or wall with bracket, follow the instructions in the relevant sec-tion. The instructions are given below for the pipes only.Before installing, carefully read the Pipe Length Check and Pressure Loss chapter to make sure thediameters, total lengths and end pieces of the pipes and their overall flow resistances do not exceedprescribed settings!

Positioning the pipes (general rules)After choosing where to position the convector on theceiling (b) or wall (a), depending on the type of pipefitting, mark the points where the holes and/or breakshave to be made in the wall.Make the centring holes with a Ø 8 mm drill, and thenwith a cutter suitable for the diameter of the pipesused.Whenever necessary, make the traps for housing thepipes, taking into account the thickness of the insula-tion to be used.

Mind that the pipes do not interfere with the faste-nings of the convector and/or of the brackets!

Mind that the recessed pipes do not alter wall resistance and affect safety!

When fitted outside, support the pipes on the wall or ceiling by securing with standard clamps.

For each of the following 2 CASES, further operations will be indicated for correct installation.

A) Fitting the pipes recessed in the wall, making chases and holes in the wall to house the pipes(Figures a and b page 24).This solution can be adopted when the wall thickness is such that stability is not affected by makingthe chases and holes for the pipes. In any case, the wall will have to be subsequently reinforced.This solution is not recommended if the walls are less than 15 cm thick.

23INSTALLER

B) Fitting the pipes beyond the wall.This solution can be adopted in case the pipes areto be kept outside the room to be heated.

The exhaust pipes must be insulated (1) using materials resistant to temperatures of over 200 °C(eg. HT/Armaflex), so that the fumes cannot condense and the surface temperature, if the pipesrun outside, does not represent a hazard for persons or things in the immediate vicinity or inclose contact.

A: Installation with pipes recessed in the wall.Before fitting the guide arms and the brackets, the masonry works will have to be performed tohouse the pipes in the wall.

A.1 - Installing the pipes (Fig. on previous page).In this case, where the inlet pipe is perpendicular to thewall and the fume exhaust pipe is parallel with the wall(turned upwards), mark the centre of the hole throughwhich the pipe passes for Ø32 pipe (F) or Ø 54 pipe(E) as previously indicated.Afterwards, before making the vertical chase, makethe holes for the inlet and exhaust pipes to pass throu-gh the wall. These should have the dimensions indica-ted on the Table on page 18.

A.2 - Installing the pipes (Fig. b on previous page).In this case, where the inlet and exhaust pipes arerecessed in the wall and can have directions of instal-lation different from the example shown, beforemaking the chases in the wall, the holes will have to bemade for the inlet and exhaust pipes to pass through as shown at para. A.1. These should have thedimensions indicated on the Table on page 18.

B: Installation with pipes beyond the wall.

B.1 - Installing the pipes (Fig. c on previous page).In this case, the inlet and exhaust pipes pass through the wall with the two pipes parallel and thencontinue in the required direction; for installation, refer to the relevant section for fitting the armsand air inlet/fume exhaust pipes.Fit the pipes, cut to size and secure with the screws provided.Secure the pipes to the wall using standard clamps.

FITTING THE STACK

The stack should be fitted in accordance with the fol-lowing requirements:- the exhaust section of the stack should be outside thereflow area to prevent the formation of counter-pressu-res that could impede combustion product exhaust intothe atmosphere;- the stack should be positioned so rain and snow can-not penetrate inside.To install, refer to applicable installation regulationsUNI CIG 7129 - UNI CIG 7131.The illustration shows how to fasten the stack to theexhaust pipe using clamp (1) and safety screw (2).

CHECKING the length and loss of pressure in the pipe

To make sure installation is such as to ensure good appliance operation, always check pipe length,total length and number of curves and relevant flow resistance. These should not exceed the maxi-mum values prescribed for the various models.For maximum allowed lengths and flow resistances, see Table 4: Maximum acceptable pipe lengthand flow resistance values.Tab. 3: Pipe check for performing the operation correctly: in column N. enter the number of piecesmaking up the pipe in relation to the type. This quantity must be multiplied by length L. (in m) andshown in column N. x L..In column Pa* enter the Flow Resistance values taken from Tab. 4 depending on the convector modeland diameter of the pipe to be installed; multiply this quantity in N. of pipe elements by the relevant flow resistance value and write the result in the column N. x Pa.Add the values found and compare them with the reference values shown on Tab. 4.By maximum allowed length is meant the sum of the total length of the air inlet pipe and the totallength of the fume exhaust pipe.By maximum acceptable pressure loss is meant the sum of all the losses caused by the straight pipes,the curves and the end pieces, in inlet and exhaust.
