Air supply
Combustion air for the stove can be supplied
through a duct directly from outside, or indirectly
through a vent in the wall of the room where the
stove is installed.
The drawings on the right show various alternative
methods of supplying the stove with air.
The air duct connection on the stove has an external
diameter of 64 mm.
The stove has two partly punched covers to provide
the option of leading the air supply duct through the
rear panel or the base-plate.
Important!
When fitting a plinth or plinth drawer, the
punche d metal section in the rear panel must
be removed completely to allow a supply of
convectio n air to the stove.
Remove the partly punched metal cover with a
hammer.
To prevent condensation in air ducts which pass
through heated areas, the duct must be insulated
with 30 mm of mineral wool covered with a proprie-
tary moisture seal (plastic vapour diffusion retarder).
It is important to seal carefully around the duct
where it passes through the wall or floor. Use joint-
ing compound. For ducts longer than 1.0 metre, the
diameter must be increased to 100 mm, and the size
of the vent increased correspondingly.
A 1.0 metre length of insulated ducting for combus-
tion air is available as an optional extra.
Important!
Leave a 40 mm gap between the condensation
insulation and the base of the stove.
