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
specific 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 sufficient
distance from the single-wall connector to provide the
required 12" (305 mm) 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 fiberglass 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" (25 mm) or more
of insulation and maintaining a minimum 2 inch air
space between the outer wall of the chimney and
combustibles.

do not connect the heater to any air distribution duct
or system.
In Canada:
The Canadian Standards Association has
established different guidelines. Figure 11 shows one
method, in which all combustible material in the wall is cut
away to provide the required 18" (450 mm) clearance 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 non-combustible spacers at least 1"
(25 mm) clear of the wall. Your Vermont Castings dealer
or your local building inspector can provide details of other
approved methods of passing a chimney connector through
a combustible wall. 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 stove 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.
