OUTSIDE COMBUSTION AIR
Your wood stove is approved to be installed with an outside air intake which is necessary for a tightly
constructed home and houses with a negative pressure problem. You can purchase this option
through your heater dealer. Make sure to specify the part number mentioned in this booklet. Instal-
lation instructions are supplied with the air intake kit.
Outside combustion air may be required if :
1. Your stove does not draw steadily, smoke rollout occurs, wood burns poorly, or back-drafts occur
whether or not there is combustion present.
2. Existing fuel-fired equipment in the house, such as fireplaces or other heating appliances, smell,
do not operate properly, suffer smoke roll-out when opened, or back-drafts occur whether or not
there is combustion present.
3. Opening a window slightly on a calm (windless) day alleviates any of the above symptoms.
4. The house is equipped with a well-sealed vapor barrier and tight fitting windows and/or has any
powered devices that exhaust house air.
5. There is excessive condensation on windows in the winter.
6. A ventilation system is installed in the house.
