11 Harman TL300
venting
The chimney
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: 3ft. - Above roof exit point
2ft. - Higher than anything within-
10ft. of the chimney.

Do not connect this unit to a chimney

noTe: The restriction of not venting more than

in Canada certain exceptions may be made. Be sure
