UNDERSTANDING DRAFT
Draft is the force which moves exhaust from the appliance up through the chimney. A properly drafting
chimney will pull the correct amount of air into the stove and will provide you with excellent performance and
heat output. Inadequate draft may cause back puffing of smoke into the room and creosote formation in the
chimney. Inadequate draft will cause the appliance to leak smoke and carbon monoxide into the room
through appliance and chimney connector joints. Factors that reduce draft are:
Too much draft may cause excessive temperatures in the appliance and may damage the internal
components of the stove. An uncontrollable burn or excessive temperature indicates excessive draft. Factors
that increase draft are:

geographical
features
A chimney that is
too short
Cold, dense or
moist air
