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 ll it with brick masonry
which is at least 3.5"(90 mm) thick. A reclay 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 TLC 2000 must be installed into a chimney approved
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-approved masonry
chimney with a ue 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 chimney.
The minimum recommended height for any chimney is
16 ft (4.8 m) above ue collar height. 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" (200 mm x 200 mm, 200 mm x 300 mm) may be used.

The 3-foot, 2-foot, 10 foot rule
Codes require that solid-fuel chimneys extend 3 ft (0.9 m)
above the point at which they exit from the roof, provided
that no part of any structure is within the top of the chimney,
then the chimney must extend 2 ft (6 m) above the highest
point with the 10 ft (3 m) radius top height. If there is not
ten feet of clearance from the top of the chimney, then the
chimney must extend 2 ft (6m) above the highest point with
the 10 ft (3m) radius.
