Fireplace chimney Installations -
Through a Fireplace
If your fireplace height is at least 25" (635 mm), you
may install an Intrepid II with standard legs through
the fireplace opening using a "positive connection" kit
available from your local dealer. These positive connec-
tion kits ensure a tight fit between the stove flue collar
and the chimney flue. (Fig. 8) Fireplace installations,
whether connected to the flue above or through the
fireplace opening, have special clearance requirements
to adjacent trim and the mantel. You'll find the required
clearances for the Intrepid II fireplace installations on
Page 14.
Floor protection requirements also apply to fireplace
installations. Floor protection information is on Page 9.

Whenever possible, design your installation so the con-

nector 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
approving installations.
Figure 9 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 open-
ing 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 sec-
tion of 9" (230 mm) diameter, solid-insulated, factory-
built chimney, with 2" (50 mm) of air space between
the chimney section and combustibles.

In canada, The Canadian Standards Association has
established installation guidelines. The following il-
lustration shows one method, in which all combustible
material in the wall is cut away to provide the required
18" (460 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
noncombustible spacers at least 1" (25 mm) clear of the
wall.
