Chimney Connector Through a Fireplace

Whenever possible, design your installation so the connec-
tor does not pass through a combustible wall. If you are
considering a wall pass-through in your installation, check
with your building inspector before you begin. Also, check
with the chimney connector manufacturer for any specific
requirements.
Accessories are available for use as wall pass-throughs.
If using one of these, make sure it has been tested and
listed for use as a wall pass-through.
In the united States,
the National Fire Protection As-
sociation (NFPA) has established guidelines for passing
chimney connectors through combustible walls. Many
building code inspectors follow these guidelines when ap-
proving installations.
Figure 8
shows one NFPA-recommended method. All
combustible material in the wall is cut away from the
single-wall connector to provide the required 12” (305 mm)
clearance. Any material used to close up the opening must
be noncombustible.
Three other methods are also recommended by NFPA:
•
Using a section of double-wall chimney with a 9” (230
mm) clearance to combustibles.
•
Placing a section of chimney connector inside a ventilated
thimble, which in turn is separated from combustibles
by 6” (150 mm) of fiberglass insulating material.
•
Placing a section of chimney connector inside a section
of 9” (230 mm) diameter, solid-insulated, factory-built
chimney, with 2” (50 mm) of air space between the
chimney section and combustibles.

A Brick Pass thru - Approved In the United States
In Canada,
The Canadian Standards Association has es-
tablished installation guidelines. The following illustration
shows one method, in which all combustible material in the
wall is cut away to provide the required 18” (460 mm) clear-
ance for the connector. The resulting space must remain
empty. A flush-mounted sheet metal cover may be used
on one side only. If covers must be used on both sides,
each cover must be mounted on noncombustible spacers
at least 1” (25 mm) clear of the wall.
Your local dealer or your local building inspector can
provide details for other approved methods of passing
a chimney connector through a combustible wall in your
area. In Canada, this type of installation must conform to
CAN/CSA-B365, Installation Code for Solid Fuel Burning
Appliances and Equipment.
NOTE:
Do not vent your Challenger into a factory-built
(zero-clearance) fireplace. These appliances and their
chimneys are specifically designed as a unit for use as
fireplaces. It may void the listing or be hazardous to adapt
them for any other use.
