INSTALLER’S GUIDE
Page 11
2.17
Propane gas appliances must not be installed in a room that is built entirely below
ground level (See BS 5871 Part 2).
2.18
If the appliance is to be fitted against a wall with combustible cladding, the
cladding must be removed from the area covered by the outer surround. The cladding
must also not touch the surround. (See figure 4). We suggest that the actual surround 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.
2.19
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.
2.20
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.
