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.
