TLC 2000 Coal Stove

The NFPA (National Fire Protection Association)
permits four methods for passing through a combustible wall.
A commonly used method to pass through a wall directly to a
masonry chimney is to clear a minimum 12"(300 mm) around
the entire chimney connector, and fill it with brick masonry
which is at least 3.5"(90 mm) thick. A fireclay liner, minimum
3/8" (9 mm) wall thickness must run through the brick wall to
the chimney liner (but not beyond the inner surface of the
liner). It must be cemented in place with refractory cement.
This method is illustrated. For details on the other three op-
tions, refer to the most recent edition of the NFPA 211 code.
The Chimney
The TLC 2000 must be installed into a chimney ap-
proved for use with solid-fuel appliances. In the U.S., the
TLC 2000 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-ap-
proved masonry chimney with a flue liner. In Canada, the
TLC 2000 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 chim-
ney.
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" (200 mm x 200 mm, 200 mm x 300 mm) may be used.
