IMPORTANT NOTES: It is important to read these instructions carefully and also note the information given on the heater itself.
As these particular instructions refer to the assembly and installation of a new heater, they should be retained by the installer; not left
behind for the user as this would invite the dismantling and servicing by unqualified persons. FOR THE USER, there is a separate
instruction leaflet explaining how the heater should best be operated. Please see that this leaflet is left with the heater for the user’s
purposes. A MEANS FOR DISCONNECTION IN ALL POLES MUST BE INCORPORATED IN THE FIXED WIRING IN ACCORDANCE
WITH THE WIRING RULES, THE INSTALLATION SHOULD BE CARRIED OUT BY A COMPETENT ELECTRICIAN. CABLE HAVING A
MINIMUM ‘T’ RATING OF 85ºC MUST BE USED. Heaters forming part of a comprehensive space heating system should be wired
with their own separate circuit, if however, 1 or 2 heaters are installed as a starter system these may be connected to a 30 amp ring
main provided that the instructions below are observed, any further heaters installed must be connected by its own circuit. If connected
to a 30 amp ring circuit the total rating of heaters connected must not exceed 3kW, where the circuit supplies a kitchen, or 4kW,
where the circuit does not include a kitchen. The storage radiator is designed to run on cheap overnight electricity, therefore the
means of connecting the heater to the ring main should include a timer. These should be connected to the supply with 3 core heat
resistant cable, the size of which is dependant on heater loading i.e. loading up to 10 amps use 1mm², up to 13 amps use 1.5mm²
and for the larger heaters 2.5mm² cable. If installed in a bathroom the heater must not be accessible to a person using a bath,
wash basin etc., and must be controlled by a fused, double pole switch within 2 metres of the appliances. It is not recommended
that a heater installed in a bathroom should be connected to a ring main circuit. The heater must not be installed immediately
below a fixed socket outlet. WARNINGS - THIS APPLIANCE MUST BE EARTHED - SPECIAL ATTENTION MUST BE PAID TO THE
SECURITY OF THE HEATER’S WALL FIXINGS. TO MAINTAIN STABILITY, IT IS ESSENTIAL THAT THE HEATER IS PLACED ON A
LEVEL SURFACE AND CARE SHOULD BE TAKEN TO AVOID IRREGULAR SURFACES, SUCH AS MAY RESULT FROM CARPETS OR
TILED SURROUNDS PARTIALLY PROTRUDING UNDER THE HEATER. IF, DURING ANY REASSEMBLY OF THE HEATER, A PART OF
THE THERMAL INSULATION SHOWS DAMAGE OR DETERIORATION WHICH MAY IMPAIR SAFETY, IT SHOULD BE REPLACED
BY AN IDENTICAL PART.
This appliance is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or
lack of experience and knowledge, unless they have been given supervision for instruction concerning use of the appliance by a
person responsible for their safety. Children should be supervised to ensure that they do not play with the appliance.
WALL FIXING: The heater must ALWAYS be mounted against, and fixed to a wall as it will not stand up by itself. A detachable
bracket is provided for screwing to the wall, the heater is then placed in position and fixed to the bracket by a screw at each end.
The heater must never be unscrewed or moved from the wall bracket whilst it is loaded with bricks. THE HEATER IS VERY HEAVY
AND WILL BE DANGEROUS IF ITS WALL FIXING BECOMES INSECURE.
Solid Brick and Concrete Walls
No. 10 Rawlplug plastic inserts. Drill
hole of 8mm dia to a depth of 15mm
greater than depth of the insert.
Panelled Wall, Paramount Board, Chipboard, Plasterboard, etc.
Check that the panel itself is adequately fixed to battens etc. Use
Rawlplug M5 intersets; drill accurate 10mm dia holes in single skin
plasterboard. One fixing should be in studwork.
Timber Frame
Seek specialist advice, some authorities suggest RAWLNUT
Hollow concrete, Breeze Block and Thermolite Block Walls
RAWLPLUG ‘RAWLOK R6054R’. Some authorities suggest UNIFIX LB
70/10mm.
PLEASE DON’T TAKE CHANCES
Site conditions may vary considerably and Creda
cannot recommend the correct wall fixings to be
used. It is the responsibility of the installer to
ensure that adequate permanent fixing has been
achieved. Purely for guidance the suggested
fixings are made for certain wall materials but this
list is not comprehensive or authoritative. Different
wall constructions will need different inserts. Note
that inserts incorporating plastic may be subject
to shrinkage behind a warm storage heater and
are therefore not recommended.
Wall fixings can be obtained from local
stockists
CARPETS: For safety, the heater must be positioned in the room so that there at least 75mm (3”) free air space all around it; under
windows, ensure that curtains, when drawn, cannot touch or cover the heater casing. In order to maintain stability, it is essential
that the heater be placed on a level surface and care should be taken to avoid irregular surfaces, such as may result from carpets or
tiled surrounds partially protruding under the heater. The heater feet are designed to go underneath a carpet rather than standing
on it; this permits the weight to be taken on a firm base and makes for neatness and ease of cleaning with vacuum cleaners, etc.
underneath the heater. Carpet gripper should be removed from behind the heater feet.
BRICKS: The heater casing and the heater storage bricks with which it must be fitted, are delivered in separate packages. The
brick is common to all heaters, packed in pairs.
The brick catalogue number is 791402015. 7934 models have 8 bricks. 7935 models have 12 bricks. 7936 have 16 bricks.

First, turn carton upside down
Open bottom flaps on carton
Packing corner fitments contain heater feet
It is preferable to fit the heater feet whilst the heater is still in its carton.
Turn the carton upside down and open the bottom flaps. The corner
fitments contain both feet and the fixing kit.
The open ends of the feet are to face forward towards the grilles in the
panel. After fitting, use the feet to lift the heater from the carton.
Cut underlay and remove carpet gripper to clear foot, allowing heater
2
weight to be taken on floor proper; lay carpet over foot, slitting it as
shown, it is unnecessary to cut carpet away.
Stand the heater against the wall in its intended position. Mark the position of the two outside
corners of the wall bracket. Carefully place the heater aside, and remove the wall bracket
from the heater by removing the screw at each end. Reposition the bracket against the wall
using the corner marks for alignment. Mark through two slots in the bracket, one at each end.
Allow mortar courses between bricks to be avoided, or battens, etc. to be found for the fixing
holes.
If mains connection is to be
made from the left hand side, at
this point the mains lead must
be secured to the back of the
heater using ties provided in the
fixing kit.
When bracket is securely fixed, replace

ends. There are two fixing slots at each end of
heater, allowing different stand-offs for different
thicknesses of skirting board. Do not fully tighten
these screws until the bricks are loaded into the
heater as some settling of the heater may occur.
NOTE: NEVER REMOVE THESE SCREWS
WITHOUT FIRST UNLOADING THE HEATER.
See also figure 1 regarding carpets where
appropriate.
Note: Max. skirting size is 15 x 120mm.
Note that the smallest wall spacing should be used only when the skirting board is of the modern slim type,
or there is no skirting board at all. THE HEATER MUST STAND VERTICAL

Temporarily remove one central element to provide
access for the rear rank of bricks.
Loosen terminals on one of the elements and remove this to
allow installation of rear rank of storage bricks. On heaters
with 3 or 4 elements remove one of the central ones.
Note the way the bricks are positioned in the heater. Otherwise they
10
will not fit.
9
Put in place the rear rank of bricks, pushing them well back
against the rear insulation. Replace the element, making
sure that the connection is tight.
Now, place in position the front rank of bricks, again
pushing them back to make room for the front insulation
slab which is attached to the front panel.
11
Check that the front insulation slab is properly attached to the inner
front panel and refit panel (insulation innermost) to the heater by
12
pushed well back, as mentioned earlier, and the insulation properly aligned, there should
be no bulging of this panel and no undue force necessary to fix it.
Refit the front / top assembly by hooking the rear edge of the top panel over the rear edge of the casing, then swing the
front panel carefully down against the casing. Replace the screws along the rear of the top and the base of the front
panel which had been removed in Step 5. ENSURE WALL BRACKET SCREWS ARE TIGHTENED FULLY.
WARNING. When a new heater is run up to temperature, the materials will produce a slight smell for the first few days,
these are normally harmless in a well ventilated room. It is best to make these first overnight charges with the ‘Charge
Controller/Auto-Set’ knob at ‘Maximum’. Caged birds, young children and people with chest ailments are best kept
out of the room for this first period.
WET BRICKS: If accidentally, the bricks have become wet due to their having been left out-of-doors, some moisture may
be driven off during the first overnight charging and this may drip on to the floor. If there is any doubt on this score,
advise the customer to lay newspaper beneath the heater to protect carpets etc. REFIT THE CONTROL KNOBS: PLEASE
OBSERVE THE FLAT ON THE ‘D’ SHAPED SPINDLE ALIGNS WITH THE FLAT ON THE KNOB BOSS.

AUTOMATIC CHARGING DEVICE (AUTO-SET Fitted only on Sensor Plus) The Auto-Set Control rations the
overnight charge each night by sensing the room temperature.
The knob is marked with the numbers 1 to 6, turning the knob to a lower number will reduce the charge consequently,
the level of room warmth the next day.
Once set, the knob should need no further adjustment and the Auto-Set will maintain automatically the room warmth
each day by varying the charge according to the weather.
1. Set the room temperature (output) control knob to setting 4.
2. Turn the Auto-Set Knob clockwise as far as it will go.
3. Leave the heater to run in this condition for two nights in order to quickly disperse the ’new’ smell which although
slight, is better removed once and for all.
4. Instruct the user to set the Auto-Set down to his chosen setting on the third day.
Instructions on this are given in the Users Guide which we ask you to ensure is left with the user.
MANUALLY ADJUSTED HEATER (without Auto-Set Control)
On this the user sets the overnight charge on the numbered knob marked ‘Input’.
Setting up procedure;
1. Turn the ‘lnput’ knob to maximum setting (6)
2. Set the ‘Output’ knob to setting No. 4.
3. Leave the heater to run in this condition for two nights in order to quickly disperse the new smell.
4. Instruct the user to set the ‘Input’ to his chosen setting on the third day. Instructions on this are given in the Users
Guide which we ask you to ensure is left with the user.
