INSTALLATION INTO STUDWORK
The following drawing details the minimum clearances and installaon
requirements from combusble materials when the appliance is installed
into a studded wall.
A chamber should be created for
the appliance outer box installaon.
The
chamber
should
be
manufactured
using
non
combusble
fire-board
of
a
minimum thickness of 9mm and the
clearances
from
combusbles
(above) should be adhered to.
Ensure
that
the
chamber
is
venlated at the base to allow cool
air to enter and venlated at the
top of the chamber to allow warm
air to be exhausted into the room.
This inlet/outlet vent should have a
minimum open area of 100cm
2
.
Connue with the installaon whilst referring to the cavity wall installaon in the previous pages. Again, care
should be taken to use a suitable non-combusble board, i.e. Promafour or similar, with no joints around the
‘hot area’. This is 500mm above the appliance and 150mm to each side. Fit plasterboard to the front and sides
of the chimney breast chamber—ensure an access area is provided for access aer installaon on one side of
this chamber.
Timber Frame Buildings
If the appliance is being installed into a mber framed building the hole through which the flue will pass must
have a steel sleeve posioned such that a minimum 25mm air gap exists between the outside diameter of the
flue pipe and the metal sleeve – in addion, contact your local building and planning authority (see safety notes
on page 3).
