Harman TL300

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.
NOTE: The restriction of not venting more than one appliance
to the same ue applies to the U.S. specically. While it is not
recommended that you use the same chimney for more than
one appliance, in Canada certain exceptions may be made.
Be sure to contact your building code inspection ofcial to
see if this option is allowed in your area, and to nd out the
specic requirements for such an installation.
Do not connect this unit to a chimney
ue servicing another appliance.
