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.
Through the Fireplace
If your fireplace opening height is at least 737 mm (29"),
you may install a Defiant through the opening using a
"positive connection" kit, available from your local deal-
er. Positive connection 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 safe clearances for Defiant fire-
place installations on Page 12.
Floor protection requirements also apply to fireplace
installations. This information is on Page 9.

Wall Pass-Throughs
Whenever possible, design your installation so the con-
ST245
nector does not pass through a combustible wall. If you
fireplace
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.
Figure 11 shows one method of passing a connctor
30003841
through a wall. All combustible material in the wall is cut
away to provide the required 457 mm (18") 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 spac-
ers at least 25 mm (1") clear of the wall.
Your local dealer or your local building inspector can
provide details for other approved methods of passing
a chimney connector through a combustible wall in your
area.
DO NOT CONNECT THE DEFIANT TO ANY AIR DIS-
TRIBUTION DUCT OR SYSTEM.

This appliance must be installed on to hearth that
meets the requirements of Part J of the Building Regu-
lations 2000 (Combustion Appliances and Fuel Storage
Systems). This can be achieved by ensuring that the
hearth is constructed and sized in accordance with the
guidelines included in section 2 of approved document
'J'. The size and clearances of the hearth are as fol-
lows:
The constructed hearth should be constructed in ac-
ST245
cordance with the recommendations in document J,
and should be of minimum width 840 mm and minimum
depth 840 mm (if a free standing hearth b) above) or
a minimum projection of 150 mm from the jamb (if a
recessed hearth a) above).
