INSTALLATION INSTRUCTIONS
PREPARATION
The heater will arrive
separately from its
storage bricks, the
following bricks will
be required:
SH6 - 4 bricks
SH12 & SH12A - 8 bricks
SH18 & SH18A - 12 bricks
SH24 & SH24A - 16 bricks
Only heat resisting cable (min. rating T85) should be
used. The wires in the mains cable will be coloured as
follows:-
GREEN & YELLOW - EARTH
BLUE - NEUTRAL
BROWN - LIVE
SUGGESTED FIXINGS
SOLID BRICK/BLOCK: No. 10 Size Plastic inserts,
8mm drill bit. Drill hole 15mm deeper than plastic insert
length.
PLASTERBOARD - If possible locate studding and use
No. 10 woodscrews directly into the wood, otherwise
M5 rawlplug intersets are suitable.
NOTE: FOR OTHER WALL TYPES (e.g. Timber frame
and hollow concrete) SEEK SPECIALIST ADVICE.
FIXING ASSEMBLY
ENSURE THAT FIXING KIT AND FEET HAVE BEEN
LOCATED BEFORE DISPOSING OF PACKAGING.
Fit the feet with the open end of the foot to the front of
the heater. Secure each foot using two taptite screws
provided in the fixing kit.
1.
2.
2.
3.
Place the heater on its feet and in the desired position
against the wall. Ensure the heater is based on a firm
level surface at least 75mm from any end wall and at least
250mm below any shelf or similar projection. Cut away any
gripper rod or carpet which would prevent the heater sitting
firmly on the floor.
4.
4.
Mark the position of the two outside corners of the wall
bracket with the heater pushed tight against the wall.
Remove the wall bracket from the heater by removing
the screw at each end. Place the heater to one side and
reposition the bracket against the wall using the corner marks
for alignment.
Four fixing positions must be chosen for the SH24, three for
the SH18 and two for the SH12 and SH6. Mark the positions
for the fixing 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 fixings previously described. Secure the wall bracket
to the wall.
5.
5.
If mains connection is to be made from the left side, at
this point the mains lead must be secured to the back of
the heater using ties provided in the fixing kit.
6.
6.
SH(A) MODELS ONLY - The Room Sensor is located
at the rear of the right hand side of the heater. Carefully
slide the sensor plate down from its transit position to its
operational position.

WARNING - This appliance must be earthed
Transit Position Operational Position

THE FOLLOWING MUST BE APPLIED WHEN
FIXING THE HEATER TO THE WALL BRACKET
7.
7.
i) If no skirting board is present secure the heater through
the wall bracket slots closest to the wall.
ii) If 100mm (4in.) skirting is present secure the heater
through the outer slots.
iii) If skirting taller than 150mm (6in.) is present this must be
reduced to 150mm (6in.) over the entire width of the heater
plus 25mm (1in.) at each end.
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.
Remove the front panel by removing the two self tapping
screws along its bottom edge. With hands positioned on
each side of the panel, lift upwards to unhook the top edge
whilst pressing down on the top panel with your thumbs. The
panel can now be lifted clear and set to one side.
8.
9.
Remove the inner front by removing the screws along its
top and sides. As the front insulation is attached care must
be taken when lifting this panel from the heater and placing it
to one side. Remove the internal packing by sliding it up and
off the elements taking care not to damage the insulation.
10.
Remove one element to allow access for the back rows of
bricks. On the SH24 remove the element to the right of
centre, on the SH18 remove the central element, on the SH12
the left hand element should be removed and, on the SH6, there
is only one element.
Loosen the two screws securing the element tails in the ceramic
connector block, and lift the element up and out of the heater.
Carefully fit the bottom row of the back layer of bricks
placing the two end bricks in position first with the re-
cess towards the element. Fit the top row of bricks also with
the recess towards the element.
11.
Refit the element which has been removed by feeding
the tails down through the hole in the base insulation and
into the connector block. Ensure the element is fully pushed
home then securely tighten the two screws in the block.
12.
12.
Fit the front layer of bricks again with the recess
towards the element. The complete core will
comprise:
SH6 - 1 x 4 Brick Columns
SH12 - 2 x 4 Brick Columns
SH18 - 3 x 4 Brick Columns
SH24 - 4 x 4 Brick Columns
Replace the inner front complete with insulation by
locating its bottom edge behind the front lip of the
chassis and inserting retaining screws along the top and
both sides.
14.
For models SH12, SH18 and SH24 only, check that
the flap mechanism operates freely on its hinges and
that with the output control set to 1 the flap is correctly seated
in its closed position.
15.
Feed the mains cable through the cable clamp and
make connections as marked on heater. Pull back any
slack through the clamp and tighten clamping screw.

OPERATING INSTRUCTIONS
This storage heater takes in Energy
when electricity tariffs are low and
dissipates it when tariffs are normal.
OPERATION
SAFETY INSTRUCTIONS
1. Ventilate rooms well during commissioning
2. Do not move the heater in any way once installed
without the services of a competent electrician.
3. Do not cover the heater with clothing etc. at any time
or position furniture close to or against the heater.
4. Ensure a clearance of at least 150mm between heaters
and curtains.
5. Floor standing heaters must only be fitted with the
back against a wall.
6. Should your heater fail to operate either employ the
services of a competent electrician or contact your
supplier.

COMMISSIONING
Set both the Input Control and the Output Control to 6
and leave the heater for 48 hours.
Following the commissioning period adjust the
controls as stated below.
CONTROL FUNCTIONS
THE INPUT CONTROL
For models SH12A, SH18A, SH24A only:
This heater is fitted with a user adjustable automatic input control
which varies the charge taken in response to weather conditions
taking into account the amount of energy already stored in the
heater.
Set at 6 the heater takes maximum charge and at 1 the heater
takes a minimum charge at any room temperature. The casing of
the heater, particularly in late evening, may feel cool, this is quite
normal. The input control may require a few days experimentation
before your comfort level is established.
Initially set the control to 4, the following evening if the room
is too warm reduce to 3 or if it is too cool increase to 5. On
subsequent evenings adjust by half divisions until our comfort
level is achieved.
Having established the setting the input will automatically carry the
amount of heat stored to compensate for weather variations.
CLEANING
To maintain the appearance of the heater wipe occasionally
with a dry cloth when the heater is cool.
Do not use abrasive powders of furniture polish.

SETTING THE CONTROLS
The controls are located on the top panel.
There are no user adjustable controls on the SH6.
For models SH12, SH18, SH24 only:
Initially set the input to 4. If the heater does not maintain a
satisfactory room temperature the following day this setting
should be increased. Conversely if the room temperature is
too high this setting should be reduced.
The input control should only require seasonal adjustments.
THE OUTPUT CONTROL
For all models except SH6
Most of the stored heat is radiated from the casing during
the discharge period. However, some of the heat is emitted
through the grille at the top of the heater and this additional
heat (or boost) is regulated by the Output Control.
With this set to 6 the boost begins in the early afternoon.
Turning the control towards 1 will progressively delay the
commencement of the boost. At 3 the boost will start in the
evening. Once set, the boost will repeat itself automatically
day after day.
If no boost is required e.g. when the room will be unoccupied
for a long period, set the Output Control to 1. With the control
in this position, the heater will take less energy during the next
charging up period.

Discolouration of wall finishes can sometimes occur
immediately above a storage heater due to the properties
of some paints and decorating materials or the presence of
environmental impurities in the air (such as soot or incense
generated from the burning of candles etc.).
