The TL300 must be installed into a chimney approved
for use with solid-fuel appliances. In the U.S., the TL300
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 ue liner.
In Canada, the TL300 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.
For mobile homes,(US only) the TL300 must only be
installed with prefabricated chimney systems, including
the installation components, tested to use in mobile
homes; the diameter should match the diameter of the
ue collar opening
The minimum recommended height for any chimney
is 16 ft (4.8 m) above ue collar height. For non-mobile
home installations, a round ue (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: - Above roof exit point
- Higher than anything within-
of the chimney.
