Electrical
The installation of this appliance should be carried out by a
competent electrician and be in accordance with the current
IEE wiring regulations.
Wall mounting
Heaters may be mounted end to end for wide doorways.
Wall or Ceiling Mounting
Solid brick or concrete block walls must be drilled and plugged
(using a spirit level as a guide ensure bracket is level) with
rawlplug No. 8 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. 8 size wood screws. If it is not possible to locate the
studding, use type M5 Rawlplug inserts, making the 10mm
holes with a drill rather than a bradawl or a screwdriver.
Installation
This appliance may be either wall-mounted or fixed to a ceil-
ing - see Fig. 2 for various fixing positions and ‘Installation’ for
details on fixing.
Using the wall mounting bracket as a guide (see Fig. 3) mark
off the hole positions on the wall or ceiling - a minimum height
of 1.8metres is required from floor to bracket. Fix the bracket
in position by following steps as described under the heading
‘Wall or Ceiling Mounting’.
