INSTALLATION METHOD 3 (continued)
Installation as per method 2 (recessing into a wall)
When setting the appliance into the wall find a suitable position between frame timbers and
open up the hole. Secure back the damp proof membrane to prevent ingress of damp.
Again 50mm insulation plus a 12 mm thick fire retardant board, 'Superlux' or equivalent, must
be provided between combustible materials and the sides and rear of the cavity box. 100 mm of
insulation plus a 12 mm thick fire retardant board, 'Superlux' or equivalent, must be provided to
the top of the cavity box. The exposed cavity should be sealed off using non-combustible board,
('Supalux' or equivalent), made into a 4-sided box. It is also good practice to further insulate the
cavity with a 50mm layer of Rockwool outside the Superlux box. Note that the appliance should
not be allowed to bridge the cavity in this installation method. It is also a good idea to enable as
much airflow as possible, into and out of the area behind the fire without causing excessive heat
loss from the room when the fire is off.
GAS SUPPLY
When the opening is ready for installation of the fire the gas supply can be routed via knockout
holes. Examples are shown in the diagram in section 6.2.
Temporarily fit the cavity box and offer up the firebox assembly to ensure a suitable gas route
can be achieved.
FINAL CAVITY BOX FITTING
If not previously carried out, insert the cavity box into the opening and mark the screw locations
required for fixing. Remove the cavity box and drill the previously marked holes in the opening
or constructional hearth area and fit rawl plugs.
Carefully insert the cavity box into the opening and guide the gas pipe through the sealing grom-
met into its final routing position and fit the restrictor inlet elbow supplied to the gas pipe.
Secure the cavity box by inserting screws in the previously prepared locations.
The cavity box may also be fitted using the cable fixing kit supplied as detailed in the next sec-
tion.
