3.3 WALL PASS-THROUGH
Occasionally it is necessary to pass the chimney connector through a combustible wall to reach the chimney. Depending on your local
building codes, and the pertinent provincial or national codes, there are several choices for accomplishing this safely. Before beginning
your installation, contact local officials, and also the chimney connector and chimney manufacturer for specific requirements.
Canada: Three methods are approved by the Canadian Standards Association. The diagram shows one method requiring an 18"
(450mm) air space between the connector and the wall. It allows use of one or two covers as described in the diagram. The two other
methods are described in detail in the current issue of CAN/CSA B365, the national standard.
United States: In the U.S., the national code is NFPA 211. While many localities adopt this standard, be sure to check with local
authorities before beginning your installation.
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 options, refer to the most recent edition of the NFPA 211 code.
3.4 THE CHIMNEY IN GENERAL
This unit must be installed into a chimney approved for use with solid-
fuel appliances. In the U.S., it 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 flue liner.
In Canada, this unit 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) it 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 flue collar opening
The minimum recommended height for any chimney is 16 ft. (4.8 m)
above flue collar height. For non-mobile home installations, 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" (200mm x 200
mm, 200 mm x 300 mm) may be used.
