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 or your local hardware store. Using a Semi-Rigid
4” dryer vent system is optimal. The outside hood must not be the type with louvers, rodent grill only.
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.
