THESE INSTRUCTIONS SHOULD BE READ CAREFULLY AND RETAINED FOR FUTURE REFERENCE

These instructions should not be left with the user, as this would invite the dismantling and servicing by unqualified persons.
There is a separate instruction leaflet which should be left with the user explaining how the radiator should be operated.
IMPORTANT SAFETY ADVICE
WARNING - This radiator is VERY HEAVY. In order to maintain stability and to ensure its future safety in use, it is essential
that the radiator is FIXED SOUNDLY TO A WALL and that the feet are mounted on a FIRM, LEVEL SURFACE. Care should
be taken to avoid irregular surfaces, such as may result from tiled surrounds partially protruding under the radiator. It is
important that the following instructions are strictly followed.
WARNING – It is important that the fixing device chosen is appropriate to the wall material to which the radiator is being
fixed. Some modern internal building materials are very low density block and require specialised fixing devices to
provide a safe, secure installation.
WARNING – If during any reassembly of the radiator, a part of the thermal insulation shows damage or deterioration which
may impair safety, it should be replaced with an identical part.
WARNING – This radiator must not be located below a fixed socket outlet.
Suggested Wall Fittings (see page 7 for further information)
Solid brick/block: No. 10 Rawlplug fibre inserts (provided). 5.5mm drill bit. Drill 8mm deeper than rawlplug length.
Plasterboard: If possible locate studding and use No. 10 woodscrews directly into the wood, otherwise M5 intersets.
For other wall types seek specialist advice.
WARNING - in order to avoid overheating, do not cover the radiator.
DO NOT COVER OR OBSTRUCT the surfaces of the appliance.
DO NOT POSITION under windows where curtains may contact the radiator (see minimum clearances above).
DO NOT PLACE OBJECTS in contact with the radiator.

DuoHeat has two heat output modes Comfort (Radiant Heat)
and Background (Retained Heat) . Under normal operation
the temperature control display will always operate the radiant
panel, (Comfort).
Note:- Front Panel should be fully installed onto radiator
and only Peak supply is switched on, with red bar(s)
showing on the temperature control display, before
starting the check procedure.
1. (i) Adjust the “off peak” control setting (Background
heat) to position no. 10 as follows; press and hold
down the +button on the temperature control display
until 10 red bars are illuminated, continue to hold
the +button for a further 7 seconds and a single
red bar will flash. Use the +button to move the
flashing red bar to the right hand side i.e. the No. 10
position (shown below).
After 20 seconds the temperature control display
will return to the Comfort control mode.
(ii) Ensure “Off Peak” supply is in the Off position.
Unscrew the spur from the wall. Check the
continuity on the storage side of the spur.. If the
circuit is closed this will confirm that the “off peak”
storage circuit (background heat) is operational.
(iii) If the “off peak” circuit shows open circuit and room
temperature is below 25°C, switch off the “peak”
front panel electricity supply and check if the circuit
has closed. If off peak circuit is still open, check all
electrical connections are secure, only then phone
