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.
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.

Closed damper will over-

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.
An outside air control handle allows you control of the out-
side air inlet if your
fi
replace is equipped with this option.
Use of outside air for combustion is highly recommended to
conserve heated air within the structure and to provide make
up air to keep the
fi
replace venting properly.
This
fi
replace will operate correctly only if adequate ventila-
tion is provided to allow proper draft to the
fi
replace sys-
tem.
See Figure 9.1 for location and operation.
CAUTION
Outside air control handle is HOT. Adjust before lighting
fi
re.
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.
E. Firescreen
A
fi
rescreen is always provided to control sparks. It must
be closed whenever the
fi
replace is in use. Glass doors or
fi
rescreens must not be used to hold burning material in-
side the
fi
replace. Only those glass doors speci
fi
cally tested
and listed for use with the speci
fi
c
fi
replace model should be
used. Screens should be closed when the glass doors are
closed.
F. Glass Doors
Most ef
fi
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.
