Before lighting the fi re, verify this by looking up from the in-
side of the fi replace. Always operate this fi replace with the
damper fully open. Please note: Down drafts, obstructions,
damaged or poor (wet) fuels can cause smoke spillage.
See Figure 9.1 for location and operation.

Fire Risk
• Close fi rescreen when burning fi replace.
• Do not use fi rescreen or glass doors to
hold burning material in fi replace.
Firescreen controls sparks.
Glass may break or burning material may
roll out.
WARNING
Fire Risk
Smoke Risk
• Doors must be fully opened or fully closed
when operating fi replace.
Partially opened doors may draw fl ame, smoke
or heat from fi replace.
WARNING
Asphyxiation Risk
Fire Risk
• Open damper to operate fi replace.
Closed damper will over-fi re fi replace and
prevent venting of combustion gases.
WARNING
B. Outside Air
A source of air (oxygen) is required in order for combustion
to take place. Whatever air is consumed by the fi re must be
replaced through cracks around windows, under doors, etc.
Most newly constructed houses or existing homes fi tted with
tightly sealed doors and windows are relatively air tight. In
this case, an outside air source must be made available to
feed combustion air from outside the home.
C. Clear Space Near the Fireplace
Combustible materials must not be stored on the hearth ex-
tension. Room furnishings such as drapes, curtains, chairs
or other combustibles must be at least 4 ft (1.22 m) from the
open front of the fi replace.
D. Flue Damper
The fl ue damper must be in full open position, and is oper-
ated by moving the handle up toward the top of the fi replace.
F. Glass Doors
Most effi cient fi replace operation using glass doors is with
the doors open. When the doors are open the screen must
be closed. Only Hearth & Home Technologies glass doors
may be used. See Figure 9.2 for proper glass door opera-
tion.
The factory installed integral grate must be used to hold the
logs from falling out of an open fi replace and to allow air to
pass between the burning logs. It is important to keep the
fi re off the hearth and to allow the ashes to collect beneath
the fi re, thereby forming a layer of additional heat protection.
H. Wood Fuel
Firewood
Your fi replace performance depends on the quality of the
fi rewood you use. All seasoned wood, regardless of spe-
cies, contains about 8,000 BTU’s per pound, and hard-
woods have a greater density than soft woods. A piece
of hardwood will contain about 60% more BTU’s than
an equal size piece of soft wood. Firewood is commonly
sold by the cord (128 cu. ft.). A cord of seasoned oak
(hardwood) would contain about 60% more potential en-
ergy than a cord of seasoned pine (soft wood).
A fi rescreen is always provided to control sparks. It must be
closed whenever the fi replace is in use. Glass doors or fi re-
screens must not be used to hold burning material inside the
fi replace. Only those glass doors specifi cally tested and list-
ed for use with the specifi c fi replace model should be used.
Screens should be closed when the glass doors are closed
