PLEASE READ THIS LEAFLET CAREFULLY AND RETAIN FOR FURTHER USE
NOTE ALSO THE INFORMATION GIVEN ON THE HEATER

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.
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.

Packing corner fitments contain heater feet
Open bottom flaps on carton
First, turn carton upside down

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
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.

The top panel and front panel are joined and should be removed as one assembly. To do this,
remove the screws fixing the rear flange of the top panel, and
remove the two screws along the bottom edge of the front panel.
Carefully swing out bottom of front panel and lift assembly
clear of casing, this operation also removes the control knobs
under the flap. Put assembly in a safe place to avoid damage
to paint etc.
WALL FIXINGS - VERY IMPORTANT
5
A clear space of at least 3” (75mm)
must be left at either side of the
heater, and any projections or
shelves must be at least 10”
(250mm) above the heater casing.
Curtains must not be draped around
or in contact with the casing. A
shelf unit is separately available for
fitting above heaters.

When bracket is securely fixed, replace
the heater under the bracket angle
and align screw holes on heaters
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
3You must fit a
retaining screw at
each end of the
heater.

CONNECTING THE MAIN’S SUPPLY CABLE
Feed the mains cable through the cable clamp and make
connections as marked on the heater. Pull back any slack
through the clamp and tighten clamping screw. Make sure
clamp is tightening on outer sheath of cable and not on
individual conductors.
79361/4/6S
79351/4/6S

ENSURE THAT CABLE CLAMP
IS SECURELY ATTACHED TO
THE CHASSIS OF THE HEATER.

Note the way the bricks are positioned in the heater. Otherwise they
will not fit. 9

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.
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.
8
10 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.

Check that the front insulation slab is properly attached to the inner
front panel and refit panel (insulation innermost) to the heater by
locating its bottom edge behind the front lip of the chassis, and
inserting retaining screws along the top and both sides. With the bricks
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 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.

SETTING THE CONTROLS
The controls are located under the lockable flap at
the right hand corner of the top panel. To adjust the
controls on the heater use a coin and engage it in the
slot provided on the top surface of the knob.
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 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.
