United States Stove 3000 (L) instruction manual Outside Combustion Air

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.
