COMBUSTION AIR SUPPLY
Fresh outside air is not required for normal residential installation. The stove consumes oxygen
during operation. It is important that you supply a source of fresh air to your stove while
burning. A slightly opened window is sufficient for this purpose. If you also have a fireplace in
your home, a downdraft may be created causing a draft down your chimney. Provide adequate
ventilation in the room.
Outside combustion air is a requirement for mobile home installation. It is also highly
recommended for tightly insulated homes and a good feature for normal installations.
A metallic 2” diameter rigid or flexible pipe should be securely connected to the air intake
connector at the back of the stove. The fresh air may be taken from outside of the house
through a hole in an adjacent wall or from the floor of houses with ventilated craw space. Be
sure not to damage the structural integrity of the house The pipe and penetrations should be
properly sealed and weather-proofed. The intake pipe should be properly terminated with a
cap or elbow to shield the inlet from the weather. The termination openings should be
protected by a rodent screen. Keep the pipe length as short as possible for optimal
performance. For best performance, keep 2” diameter intake pipe length under 10 feet. If
longer runs are required, use an adapter to connect to 3” diameter intake pipe.
Outside air can also be obtain by installing a listed direct-vent system for pellet stoves. Follow
the vent manufacturer’s instructions.
Never draw outside combustion air from a wall, floor or ceiling cavity or from any enclosed
space such as an attic, garage, carport or under a mobile home.
