Special instructions on fitting the heater to
a wall or ceiling:-
Solid brick or concrete block walls must be drilled and
plugged with Rawlplug No 10 size FIBRE inserts. The plug
must be located in the solid part of the wall, not just in the
plaster layer.
For panelled internal walls or ceilings, it is best to locate
the studding, position the heater fixing bracket accordingly
and use No 10 size wood screws. If it is not possible to
locate the studding, use type M5 Rawlplug INTERSETS,
making the 10mm holes with a drill rather than a bradawl or
a screwdriver.
