Combustible Walls & Timber Framed Dwellings
The appliance may be fitted directly to wall made both from combustible and
non combustible material. If it is to inset into the wall, the inner wall plate
(supplied separately) must be used and a gap of 25mm should be maintained
between the top, rear and sides of the convector box and any combustible
material. These gaps should be filled with mineral wool insulation.
A gap of 50mm must be maintained between the outer flue and any combustible
material including the external wall. This gap must be filled with mineral wool
insulation.
Installations into timber framed dwellings must follow the recommendations of
IGEM/UP/7 ‘Gas Installation in Timber Framed Buildings’ available from The
Institute of Gas Engineers and Managers’. The appliance must not be inset
unless provision has been made by the builders with the approval of the
designers of the dwelling.
Fitting
This appliance can be installed either by being fixed directly on to the surface or
it can be inset into the inner leaf of a cavity wall. Before starting the installation
remove the glass door by unscrewing the eight nuts securing the door and place
in a safe place until required.
Undoing the nuts and bolts on the outer flanges of the appliance separate the
heat exchanger from the convector box.
Surface Installation
1
Select a position for the appliance and mark the centre of the flue. This should
be at least 700mm above finished floor level. (This is to give sufficient clearance
to allow the door to drop down). The centre of the glass panel will be 157mm
below this mark (See Figure 2). At this position drill a 152mm diameter hole in
the wall for the flue. Apply white foam tape (supplied) around the edges of the
back of the convector box to form a dust seal between the box and the wall.
2
Thread the outside Terminal plate onto the flue and push the flue into the wall
from the outside. Apply mastic to the rear face of the Terminal plate and fix to
