CHIMNEY CONNECTION

Two basic types of chimneys are approved for use with solid fuel. Factory-built and ma- sonry. Factory-built chimney must comply with UL/ULC standard in the US and Canada.

Do not expect your stove or furnace to create draft. Draft is not a function of the appliance. Draft is purely a function of the chimney. Mod- ern stoves and furnaces are much more air- tight and efficient than those of the past, and, therefore, require greater draft. A minimum of

.05" measured in water column (gauges to measure chimney draft are readily available at stove shops and are economical to pur- chase or rent) is required for proper drafting to prevent back-puffing, smoke spillage, and to maximize performance.

Chimneys perform two functions - one of which is apparent: The chimney provides a means for exhausting smoke and flue gases resulting from combustion of the fuel. Secondarily, though, the chimney provides "Draft" which allows oxygen to be continuously introduced into the appliance, so that proper combustion is possible. As of April 1, 1987, all wood heaters and furnaces manufactured by United States Stove Company should be installed using a factory-built chimney that meets the "Type HT" requirement of UL 103 (when a factory-built chimney is used).

A chimney connector shall not pass through an attic, roof space, closet, floor, ceiling, or similar concealed space. Where passage through a wall or partition of combustible con- struction is desired, the installation must con- form with NFPA 211 or CAN/CSA-B365.
