unvented gas log set.
GLASS DOORS
Bi-fold glass doors are optional with this firebox.
They come in brushed or polished brass.
To install glass doors, refer to installation
instructions that are included with kit. When
firebox is in operation, doors must be fully open
or fully closed position only or a fire hazard may
be created (see Figure 30 or 31).
A firebox equipped with glass doors operates
much differently than a firebox with an open
front. A firebox with glass doors has a limited
amount of air for combustion. Excessive heat
within the firebox can result if too large a fire
is built or if combustion air gate is not com-
pletely open.
The following tips should be followed to as-
sure that both the firebox and glass door retain
their beauty and function properly:
• Both the flue damper and glass doors must
be fully opened before starting fire. This
will provide sufficient combustion air and
maintain safe temperatures in firebox.
• The glass must be allowed to warm slowly
and evenly. The tempered glass will with-
stand a gradual temperature rise to 550° F,
which is more than a normal fire will gen-
erate. Such materials as pitch/wax laden
logs, very dry mill end lumber and large
amounts of paper or cardboard boxes.
Always keep the fire well back from the
doors and never allow flames to contact
the glass.
WARNING: Fireplaces
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.
