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.
TO ENSURE THIS APPLIANCE IS OPERATING CORRECTLY, IT IS ESSENTIAL TO PERFORM THE CHECK PROCEDURE DETAILED
ON THE BACK PAGE OF THIS INSTRUCTION. THIS MUST BE COMPLETED BEFORE NORMAL OPERATION COMMENCES.
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.
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.
