the Chimney
This unit must be installed into a chimney approved for use
with solid-fuel appliances. In the U.S., it 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 flue
liner.
In Canada, this unit 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 flue collar height. 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" (200mm 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 highest point at which they exit from the roof. Then,
the chimney must extend 2 ft.(6 m) above the highest point
within a 10 ft (3 m) radius. Thus, the 3 foot, 2 foot, 10 foot rule:
3ft. - Above roof exit point
2ft. - Higher than anything within-
10ft. of the chimney.
Do not connect this unit to a chimney flue servicing
another appliance.
