9.4 Supply of Combustion Air
9.4.1 Mobile Home
This stove is approved to be installed in a mobile home. It must therefore have a supply of
combustion air from outdoors. The air intake must not draw air from the attic, from the basement,
from a garage or any enclosed space. Air must be drawn from a ventilated crawl space under
the floor or directly from outside.
Install a flexible or rigid, insulated pipe (HVAC type, must comply to ULC S110 and/or UL
181, Class 0 or Class 1) to the fresh air intake. The outside termination must have a weather
protection cap with a wire mesh. Where a mobile home has been converted to a standard house
by mounting it on a permanent basement foundation, the supply of outdoor air is not mandatory.
9.4.2 Conventional House
The safest and most reliable supply of combustion air for a wood stove is from the room in
which it is installed. Room air is already preheated so it will not chill the fire, and its availability
is not affected by wind pressures on the house. Almost all houses have enough natural leakage
to provide the small amount of air needed by the stove. The only case in which the wood stove
may not have adequate access to combustion air is if the operation of a powerful exhaust device
(such as a kitchen range exhaust) causes the pressure in the house to become negative relative
to outdoors.
Figure 15: Air supply in conventional houses
If an air intake is installed through the wall of the house, its pressure can vary during windy
weather. If smoke puffs from the stove, the air duct should be disconnected to determine if it is
the cause of the problem. In some windy conditions, negative pressure near hood may draw hot
exhaust gases from the stove to outdoors. Check the outdoor air duct for soot deposits when
the full system is cleaned and inspected at least once each year.
