GUIDELINES
GLASS DOORS
Glass doors are optional with the fireplace. When
the fireplace is in operation, doors must be fully
opened or fully closed position only or a fire hazard
may be created (see Figure 28).
A fireplace equipped with glass doors operates
mush differently than a fireplace with an open
front. A fireplace with glass doors has a limited
amount of air for combustion.
Excessive heat within the fireplace can result if too
large a fire is built or if the combustion air gate is
not completely open. The following tips should
be followed to assure that both the fireplace and
the glass door retain their beauty and function
properly. Both the flue damper and the glass doors
must be fully opened before starting the fire. This
will provide sufficient combustion air and maintain
safe temperatures in the firebox.
IMPORTANT: The glass must be allowed to
warm slowly and evenly. The tempered glass will
withstand a gradual temperature rise to 550° F,
which is more than a normal fire will generate.
Such materials as pitch/wax laden logs, very dry
mill end lumber and large amounts of paper or
cardboard boxes can create an excessively hot fire
and should not be burned in this fireplace. Always
keep the fire well back from the doors and never
allow flames to contact the glass.
WARNING: Fi r eplaces
equipped with glass doors
should be operated only with
doors fully opened or doors fully
closed. Doors, if left partly open,
may draw gas and flame out of
the fireplace opening creating
risks of both fire and smoke.
Cleaning the Glass
Clean the glass with any commercial glass cleaner
or soap and water. Do not use any abrasive mate-
rial to clean the glass. Do not clean the glass with
any cool water is the glass is still hot from the
fire and smoke.
A gas line or gas log lighter may be installed for the
purpose of installing a vented or vent-free deco
-
rative gas appliance incorporating an automatic
shutoff device and complying with the Standard
for Decorative Gas Appliances for Installation in
Vented Fireplaces, ANSI Z21.60 or American Gas
Association draft requirements for Gas Fired Log
Lighters for Wood Burning Fireplaces, Draft NO.
4 dated August, 1993.
If you wish to install an unvented (vent-free) gas
log set, only unvented gas log sets which have been
found to comply with the standard for unvented
room heaters, ANSI Z21.11.2 are to be installed
in this fireplace.
OUTSIDE AIR AND DAMPER
HANDLE OPERATION
The damper handle, which opens and closes the
damper blade, is located in the upper front face of
the fireplace. Pushing the handle forward and up
of the keyway slot will free the damper blade to
automatically open. Pushing the handle forward
and down will lock the damper blade closed (see
Figure 29, page 22).
The outside air kit lever is located at the left and
right hand sides of the fireplace (see Figure 30,
page 22) Lifting the lever up will free the outside
air door to open. Pulling the lever down will lock
the door.
