OPERATION AND MAINTENANCE GUIDELINES
Figure 21 - Glass Doors
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 21).
A fireplace equipped with glass doors oper-
ates mush differently than a fireplace with an
open front. A fireplace with glass doors has a
limited amount of air for combustion. Exces-
sive 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 as-
sure 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: 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.
Cleaning the Glass
Clean the glass with any commercial glass
cleaner or soap and water. Do not use any
abrasive material 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 decorative 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.
