[d] connection for air feed
with closed fire
[e] valve which can be opened
to compensate for significant
consumption of room air by the
stove in open fire mode
Direct connection of the stove to
outside air
The combustion air is controlled in 3
ways:
The outside vent
[figure 4-a] and [photo 5] prevents
the house from becoming cold
when the stove is not in use. This
vent can be controlled from inside
provided it is not too far away from
the stove. It must be protected by a
grill, [figure 4-c] which has a section
of free passage of at least 200 cm
2
.
It is installed as close as possible to
the outside to restrict heat loss. The
distance between the two valves
does not matter. Be aware of pressure
loss if the intake duct is too long.
Compensate with a greater diameter
and/or smoother tubing.
An “open fire” valve
[figure 4-b] and [photo 6] designed to
increase outside air intake when the
stove is working in open fire mode
and therefore using lots of air. This
valve is particularly useful in energy-
efficient homes. It is installed behind
or under the stove and its control is
fitted under the stove.
3 installation possibilities : the outside
air duct comes out of either:
– the wall, behind the console
[figure 7] The valve is fitted at the
back of the wall (if necessary use a
duct extension 160 mm in diameter
as this ends flush with the wall).
– the wall, under the console
[figure 8]
– the floor [figure 9] the stove is fed
by a duct 63 mm in diameter.
The valve
of the stove enables fine
regulation of air intake to control
combustion with the stove closed.
