The volume must be divided by the volume to obtain a ratio of communicating spaces required.
A natural draft stove is a stove that uses natural atmospheric pressure to force combustion exhaust gases out through a ventilation system. As the fuel burns in the furnace, hot air and combustion by-products such as carbon monoxide and nitrogen dioxide are produced.
The top opening should be as close to the ceiling as possible and no lower than the minimum draft limiter. The bottom opening should be 6 to 18 inches off the ground. It offers varying degrees of draft control and mixes dilution air with the flue gas to reduce the potential for condensation.
