Normal adventitious ventilation is usually sufficient to satisfy the ventilation
requirements of this appliance. In GB reference should be made to BS 5871 Part 2
and in IE reference should be made to the current edition of IS 813 “Domestic Gas
Installations” which makes clear the conditions that must be met to demonstrate that
sufficient ventilation is available.

If the appliance is to be fitted against a wall
with combustible cladding, the cladding must be
removed from the area covered by the fascia. The
cladding must also not touch the fascia (See figure
4). We suggest that the actual fascia is used as a
template to mark the area for combustible cladding
removal and that this area is increased by at least
2mm all round.

The minimum height from the base of the
fireplace opening to the underside of any shelf
made from wood or other combustible materials is
detailed below.
•
For a shelf up to 150mm deep
: Minimum height =
700mm.
•
For a shelf deeper than 150mm
: 700mm +
12.5mm for every 25mm depth over 150mm (See Graph 1).
