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.

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
