GAS SUPPLY ROUTES
The gas supply may enter the fire over the hearth or by concealed connection behind the fire.
Following preparation of the fixing method, the concealed gas supply (if required), can now be
installed.
When the opening is ready for installation the gas supply can be routed. If the gas pipe has been
sleeved the ends of the sleeving must be sealed. The end of the 8mm pipe should be temporar-
ily sealed to prevent the ingress of debris during fixing.
An isolator cock or or restrictor elbow must be fitted to the incoming supply to facilitate servic-
ing.
Concealed pipes should not be routed through walls without being protected by sleeving or con-
duit.
INSTALLATION METHOD 1 (against a non-combustible inside wall)
This method requires no modifications to the internal wall of a property and is achieved by
using either a surround with extended rebate or a false chimney breast of minimum 90mm
internal depth.
A false chimney breast should be installed, taking into account any guidance given in the section
on timber framed buildings as far as insulation and clearances are concerned. As a general rule,
when the false chimney breast is constructed from combustible materials the cavity box must be
separated from any combustible materials by a minimum 75mm air gap at the sides and rear and
100mm air gap above the cavity box. Alternatively the cavity box may be insulated with 75mm
of fibre glass wool or rock wool to the sides, rear and 100 mm to the top.
Finally install the fireplace or fire surround and back panel/marble to its finished location.
