the chimney

The Oakwood must be installed into a chimney approved
for use with solid-fuel appliances. In the U.S., the Oakwood
must be connected to (1) a prefabricated chimney complying
with the requirements for Type HT chimneys in the Standard
for Chimneys, Factory-Built, Residential Type and Building
Heating Appliances, UL 103, or (2) a code-approved masonry
chimney with a tile flue liner. In Canada, the Oakwood is listed
for use with prefabricated chimneys tested and listed to the
high temperature (650 degrees C) chimney standard, ULC
S-629, or with a code approved masonry chimney.
The minimum recommended height for any chimney is 16 ft
(4.8 m) above the flue collar height. For non-mobile home
installations, a round flue (either masonry or approved
prefabricated), of either 6" (150 mm), 7" (180 mm) or 8"
(200 mm) may be used. For square or rectangular masonry
chimneys, nominal sizes of 8" x 8" or 8"x 12" (200 mm x 200
mm, 200 mm x 300 mm) may be used.
Codes require that solid-fuel chimneys extend 3 ft (0.9 m)
above the point at which they exit from the roof. The chimney
must extend 2 ft (6 m) above the highest point within a 10 ft
(3 m) radius of the top of the chimney. Thus, the 2 foot, 3 foot,
10 foot rule; "The top of the chimney must be a minimum of
3 feet above where it exits the roof, and 2 feet higher than
anything within 10 feet."
