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 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.
3.18 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.
3.19 The minimum allowable distance from the outside of the appliance fascia 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).
3.20 The appliance is fitted with an A.S.D (Atmosphere sensing device). If the
appliance closes down after a period of operation for no apparent reason, the consumer
should be informed to stop using the appliance until the installation and appliance have
been thoroughly checked. The A.S.D will shut the appliance down if an unacceptable
amount of harmful products of combustion accumulate. Under no circumstances should
the A.S.D be altered or bypassed in any way. Only a genuine manufacturers replacement
part should be fitted. The individual A.S.D components are not replaceable.
3.21 A fireguard complying with BS 8423 should be fitted for the protection of young
children, the elderly, or the infirm.
