INSTALLATION
WALL PASS-THRUS
Whenever possible, design your installation so the connector does not pass through a combustible wall. If you must use a wall pass-
through in your installation, check with your building inspector before you begin and construct it in accordance with local building
codes. Also, check with the chimney connector manufacturer for any speci
fi
c requirements.
Accessories are available from your dealer 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.
All combustible material in the wall is cut away a suf
fi
cient distance from the single-wall connector to provide the required 12
"
(305mm) clearance for the connector. Any material used to close up the opening must be non-combustible.
The following wall pass-through methods
may be
approved in your area:
•
Use a section of listed factory-built chimney with a nine-inch clearance to combustibles.
•
Place a chimney connector pipe inside a ventilated thimble, which is then separated from combustibles by 6"(152 mm) of
fi
berglass insulating material.
•
Place a chimney connector pipe inside a section of listed solid-insulated, factory-built chimney, with an inside diameter
1" (51 mm) larger than the chimney connector and having 1" (25mm) or more of insulation and maintaining a minimum
2 inch air space between the outer wall of the chimney and combustibles.
