A pellet stove has a combustion blower that pulls outside air into the stove through a fresh-air vent and then blows out smoke and fumes through a stainless-steel exhaust vent. Theres also a convection blower that draws room air into the stove and blows heated air into the room through a series of heat-exchange tubes.
