1. Invert the carton and carefully lift carton off heater. Do

not remove internal packaging pieces at this stage! 2. Remove the feet and accessories bag from corner

fittings (accessories bag is located within one of the feet).

3. Secure the feet to base of heater using the Taptite

screws provided (two for each foot). It is necessary on

XL12N/XLS12Nmodels, toremove basecorner packaging

pieces to locate feet in position.

4. Loosen hexagon head front panel securing screws, by 1

-2 turns using screwdriver through aperture ineach end

packingpiece.

7. Position heater against wall in intended final position,

taking note of the minimum fixing dimensions.

If fitted, the Dimplex storage heater shelf should be fixed

in accordance with the instructions enclosed with the

shelf.

8. If the floor is carpeted then the carpet should be slit and

underlay cut away to allow the feet to rest firmly on the

floor. Carpet gripper must be locally removed so that the

feet may rest in a level position. 9.Having prepared,where necessary,the floor, the

position of the wall bracket should be marked on the wall.

external sensor

The sensor is situated at the rear of the lower right corner

of the heater.

a) Remove sensor carefully from its retaining clips and

move to one side.

b) Slide down plastic sensor carrier as far as it will go so

that the two plastic fixings are above the retaining notches.

Replace sensor carefully in its retaining clips.

12.Solid Brick/High Density Block Walls. (See step 13 if

walls are low density block.) These must be drilled and

pluggedwith the Rawlplug No.10 size fibre inserts

provided. The correct size of drill (5.5mm) should be used

and the hole should be drilled to a depth of 6mm greater

that the length of the Rawlplug so that the fixing is made

belowthe plasterlayer.

13. Low Density Block Walls. Aspecialised fixing, such

as the Unifix LB70, should be employed following closely

themanufacturer’sinstructions.

Panelled Internal Walls. Here it is best to locate the

studding and use No. 10 size woodscrews. Where it is not

possible to locate the studding use type M5 Rawlplug

INTERSETSon securely fastenedplasterboard panelling.

Forother wall panel materials the wall panel manufacturer

should be consulted for details of suitable wall fixing

devices.

10. Remove wall fixing bracket from heater by removing

the screws at each end.

11. Mark wall bracket fixing positions and screw wall bracket

to wall following closely the guidelines in steps 12 and 13.

NOTE: It is essential that two of the fixing points are the

lower short fixing slots at each end of the wall bracket.

14. If left hand cable connection is required, the cable

support straps supplied in the fixing kit should be fitted to

the base of the rear of the heater, and the supply cable fed

through them. Ensure sufficient spare cable is fed through

the straps to make the mains connection.

15. Secure heaterto wallfixing bracket by replacing thetwo

screws removed in step 10 (do not fully tighten these screws

until the bricks are loaded into the heater as some settling of

theheatermayoccur).Thefeetandwallmountingarrangement

are designed to accommodate skirting board sizes up to

25mm(1”)thick.Toavoidobstructingtheairflowtothe rear

oftheheaterthe following must bestrictlyadheredto:

(a) For skirtings higher than 100mm (4”) it will be necessary to

positiontheheaterwith the screwsattachedthroughthe

alternative fixing slots to the front.

(b) For skirtings having a height in excess of 150mm (6”) it will

be necessary to reduce the height of the skirting to 150mm

(6”)overtheentire lengthofthe heater plus25mm(1”) ateither

end.

elements, taking care not to damage the insulation.

24. Replace the element which had been removed by

carefully passing the ends through the base insulation

slots into the terminal blocks below. Position the insulator

on the element end in contact with the terminal block

ceramic as shown, and tighten the connection screws. At

this point check that all element connections are tight.

25. Fit the front bricks with the airways facing inwards.

26. Re-fit the inner front panel/insulation assembly,

ensuring the bottom edge of the panel is located behind the

base flange. Make sure all screws removed in Operation
