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. 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.
Use Drill for accurate hole, not hammer or chisel.
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. 7933 models have 4 bricks.

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
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. Two fixing positions must be
used for the 79331/4/6S.
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 the heater under the
bracket angle and align screw
holes on heaters ends.

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. 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.

HEATER OPERATION
The TSR6MW and TSR6AW Storage Heaters store heat overnight using cheap off peak electricity and discharge
this heat the following day. The TSR6MW is preset at the factory to always take a full charge. The TSR6AW
models are fitted with an external sensor which measures room temperature and adjusts the input to the heater
automatically, thus ensuring the most effective use of electricity. These operating instructions assume that the
correct size of storage heaters have been selected to cater for the heating requirements of the room.
Instructions on this are given in the Users Guide which we ask you to ensure is left with the User.
IMPORTANT NOTICE TO INSTALLER
TSR 79331S MODEL
To ensure that the correct charge level is achieved by the heater, the flat surface of the charge control thermostat spindle MUST be
positioned towards the rear of the heater and parallel with the wall. (This should have been factory set.)
THERMAL OVERLOAD
PROTECTION
This appliance is protected by a thermal safety
cutout which will operate to isolate the electricity
supply if, for example, the heater surfaces or
grille are obstructed to cause overheating.
The cutout should not operate if the instructions
given in this leaflet and clearances regarding
positioning are strictly followed.
