hours of the commissioning period.

1. Invert carton and lift carton off heater. Take care to ensure that staples

in carton !aps do not scratch surface of heater. Do not remove internal

packaging pieces at this stage.

Assembly of heater

2. Remove feet and accessories bag from corner "ttings (accessories bag

is located within one of the feet.)

3. Secure feet to base of the heater using two Taptite screws (provided)

for each foot. (On modules CXL12N/CXLS12N it would be necessary to

remove base corner packaging pieces to locate feet in position). Apply

end pressure whilst turning screws so that they form their own thread in

the plunged holes in the base.

4. Loosen hexagon head front panel securing screws, by 1-2 turns using

screwdriver through aperture in each end packaging piece.

Stand heater on its feet and remove all packaging pieces.

5. Position heater against wall in intended "nal position, taking

note of the minimum "xing dimensions given below. If "tted, the

Dimplex storage heater shelf should be "xed in accordance with

the instructions enclosed with the shelf.

Special instructions for !tting the heater to the wall.

6. Fitting on the top of carpet. If the heater is to stand on top of the carpet the following

course of action MUST be taken. Ensure that any carpet gripper (e.g. “Gripperod”) is

removed from the !nal positions of the storage heater feet. Ensure that the carpet AND

underlay completely cover the area under the feet so that they stand on a level surface.

If the underlay is particularly thick it is advisable to cut it away completely from under the

feet and for a suf!ciently wide area around the feet for them to rest !rmly through the

carpet onto the "oor.

7.Fitting directly on the "oor. If the !oor is carpeted then the carpet

may be slit and underlay cut away to allow the feet to rest "rmly on the

!oor. Carpet gripper must be locally removed so that the feet may rest in

a level position.

8. Having decided on the method of standing the heater on the !oor the

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

9. Remove wall "xing bracket from heater by removing the screws and

spacer bushes at each end.

11. Solid Brick/High Density Block Walls. (See step 12 if walls are of

low density block) These must be drilled and plugged with the No. 10 size

plastic inserts provided. The correct size of drill (8mm) should be used and

the hole should be drilled to a depth of 15mm greater than the length of the

plastic insert, so that the "xing is made below the plaster layer.

12. Low Density Block Walls. A specialised "xing, such as the Uni"x LB70.

should be employed following closely the manufacture’s instructions.

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 INTERSETS on securely fastened plasterboard

panelling. For other wall panel materials the wall panel manufacturer should

be consulted for details of suitable wall "xing devices.

10. Four "xing positions must be chosen for the 24N, three

for the 18N and two for the 12N . Mark the positions for

the "xing holes - two at the extreme ends and the others

spaced evenly between them. Remove the bracket from

the wall, drill the holes in the positions marked, and insert

suitable "xings detailed in Steps 11 and 12. Secure the

wall bracket to the wall.

13. At this point determine which side of the heater off peak and on peak

supplies are to be connected. If off peak supply is to be connected from

the right hand end and on peak from left hand end proceed to next step.

If wiring of the building does not correspond with these cable entry points

then it will be necessary to secure the cable to the base of the rear of the

heater using the ties supplied in the "xing kit, ensure there is suf"cient

cable free to make connection easier later on.

14. Secure the heater to wall "xing bracket by replacing the two screws

and spacer bushes removed in step 11. The feet and wall mounting ar-

rangement are designed to accommodate skirting board sizes up to 25mm

(1”) thick. To avoid obstructing the air"ow to the rear of the heater the

following must be strictly adhered to:

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

the heater with the screws attached through the alternative "xing slots to

the front.

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

to reduce the height of the skirting to 150mm (6”) over the entire length of

the heater plus 25mm (1”) at either end.

15. Remove bottom front panel securing screws. These were loosened in

step 3 and should be easily unscrewed by hand.

16. Pull bottom of front panel forward to disengage the location pegs from

the side panels and clear it from bottom of heater.

17. Still holding bottom of front panel forward, lift upwards (1), to disengage

top edge of front panel from groove on heater top panel and remove front

panel from heater (2).

18. Remove the screw securing the convector controls bracket to the side

panel along with the spacer, nut and washer, taking care to ensure that

the retaining nut is not dropped

19. Remove the convector circuit mains block and insulation card from

the left side of the base panel. Unclip the wires running across the heater

below the inner front.

20. Remove screws retaining front inner skin.

21. Carefully lift the bottom of the front inner skin panel out of the retaining

!ange at the base of the heater, taking care not to damage the insulation,

hydraulic thermostat probe, heating elements and other vulnerable

components attached to this panel.

22. Remove the internal packing by sliding it up and off the elements, taking

care not to damage the insulation.

23. Remove one element to allow access for the back row of bricks. On the

CXL24N/CXLS24N remove the element to right of centre, on the CXL18N/

CXLS18N remove the central element and on the CXL12N/CXLS12N

remove the left hand element. Loosen the two screws securing the element

tails in the ceramic block, and lift the element up and out of the heater.

24. Position the bottom rear layer of bricks with the airway restrictions

coincident with the air slots in the base insulation slab. Push the bricks

"rmly to the back of the heater. Fit the top rear row of bricks, with the

airway restrictions uppermost.

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

27. Re-"t the front panel/insulation assembly, ensuring the bottom edge

of the panel is located behind the base !ange.

28. Make sure all screws removed in operation 20 are replaced

securely.

29. Replace the spacer nut, washer and screw removed in 18 and reconnect

the two quick connect terminals removed in 19.

30. Connect the off peak supply to the storage terminal block at the right

side of the base panel.

Replace the convector terminal block and insulation card at the left side

of the base panel, clip wires running across heater and connect peak

supply.

HEAT RESISTING CABLE MUST BE USED.

NOTE: ON NO ACCOUNT SHOULD SURPLUS CABLE BE STUFFED

INSIDE THE HEATER. Make sure clamp is tightening on outer sheath

of cable and not on individual conductors.

WARNING: THIS APPLIANCE MUST BE EARTHED. CHECK ALL

ELECTRICAL CONNECTIONS FOR TIGHTNESS.

ENSURE THAT CABLE CLAMP IS

SECURELY ATTACHED TO THE

CHASSIS OF THE HEATER.

31. Check that the damper mechanism within the heater functions freely,

by rotating the left hand control knob. Check also that the right hand (input)

knob rotates freely.

32. Select the convector heater load appropriate to your recommended

heating design scheme by, if necessary, disconnecting one convector

element by moving either the brown or mauve wire to the empty barrel on

the white terminal block on the internal baf!e.
