The fireplace damper must be sealed to prevent room
air from escaping up the flue. However, it must be
possible to re-open the damper to inspect or clean the
chimney.
FIREPLACE ChIMNEY INSTALLATIONS -
ThROuGh A FIREPLACE
If your fireplace height is at least 25” (635 mm), you may
install an Challenger with standard legs through the fireplace
opening using a “positive connection” kit available from
your local dealer. These positive connection kits ensure
a tight fit between the stove flue collar and the chimney
flue.
Figure 13.
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 theChallenger
fireplace installations on
Page 17
.
Floor protection requirements also apply to fireplace instal-
lations. Floor protection information is on

WALL PASS-ThROuGhS
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 14
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.
