performance of the appliance. Note the spillage test requirements detailed further on in
this manual. If the fan is likely to affect the appliance, the appliance must not be
installed unless the fan is permanently disconnected.
3.15
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.
3.16
Propane gas appliances must not be installed in a room that is built entirely below
ground level (See BS 5871 Part 2).
3.17
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 fasia
(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.
3.18
The minimum allowable distance
from the outside of the appliance case to
a corner wall having combustible
material or any other combustible
surface which projects beyond the front
of the appliance is shown in figure 5.
A 10mm access clearance from a non-combustible surface is necessary at the left side.
(See figure 5).
3.19
Proprietary terminals must comply with BS 715 or BS 1289. Any terminal or
termination must be positioned in accordance with BS 5440 Part 1 to ensure that the
products of combustion can be safely dispersed into the outside atmosphere. Where the
appliance is connected to an unlined brick chimney it is generally unnecessary for the
chimney pot to be replaced or for a terminal to be fitted unless the flue has a diameter
smaller than 170mm.
