7.
Installation method 1
Fitting against the inner face of
a
wall
with
a
suitably
constructed false chimney breast
or rebated fire surround which
encloses the depth of the
appliance.
7.1.1
This
method
of
installation
requires
no
modifications to the wall of the
property.
7.1.2 Decide on the location of
the appliance and construct and
install a false enclosure for the
product taking account of the
recommendations
regarding
combustible materials.
7.1.3 The construction and size
of the false enclosure shall be
considered with the need to use
suitable
non
combustible
insulating
materials
where
applicable to the top, rear and
sides of the appliance.
Any wall coverings shall be
removed within the enclosure
and any paper backed plaster
board on the wall face location
shall be protected or replaced
with
plaster
or
rigid
non
combustible insulating board. If
installing on the inside wall of a
timber framed dwelling, as a
precaution the wall area to the
rear of the appliance location shall be protected with rigid non combustible insulating board or 50
mm thick rock wool or similar.
A cavity box CAV4111 can be used to simplify the process of building the enclosure. If this is used
then clearances to combustible materials can be reduced to 25mm at the rear and sides of the
appliance and 50mm over the top.
