2.16
The appliance must be
mounted on a non-combustible
hearth in accordance with
Figure 4. The hearth material
must have a minimum thickness
of 12.5mm (1/2”). The
periphery of the hearth (or
fender) should be at least 50mm
above floor level to discourage
the placing of carpets or rugs
over it.
2.17
Propane gas appliances
must not be installed in a room,
which is built entirely below
ground level (See BS 5871 Pt2).
2.18
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.
