U.S. Requirements:
The National Fire Protection Association (NFPA) has
established guidelines for use in the United States for passing
chimney connectors through combustible walls. Many
building code inspectors follow these guidelines.
Figure 5.6 shows one NFPA-approved method. All
combustible material in the wall is cut away to provide 12”
(305 mm) clearance to the connector. Brick and mortar are
used to enclose the clearance area.
Connection Through the Fireplace:
If your fireplace opening height is at least 21-1/2" (546 mm),
you may install a stove through the opening using a “positive
connection” kit available from your local dealer. These kits
provide a secure connection between the stove flue collar
and the chimney flue.
Confirm that the stove location is within the required clearance
specifications for the mantel and surrounding fireplace trim.
Refer to Section 4 - Wall Shields.
Floor protection requirements also apply to fireplace
installations. Refer to Section 4 - Floor Protection.
Wall Pass-throughs:
Whenever possible, design the installation so that the
connector does not pass through a combustible wall. If you
must include 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.
Consult with your dealer regarding special connection
components available for use as wall pass-throughs. Use
only parts that have been tested and listed for use as a wall
pass-through.
