GLASS DOORS
Glass doors are optional with this fireplace.
When fireplace is in operation, doors must be
fully opened or fully closed position only or a
fire hazard may be created (see Figure 23).
A fireplace equipped with glass doors oper-
ates much 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 fireplace can result if too large
a fire is built or if combustion air gate is not
completely open.
The following tips should be used to assure
that both fireplace and glass door retain
their beauty and function properly. Both
flue damper and glass doors must be fully
opened before starting a fire. This will provide
sufficient combustion air and maintain safe
temperatures in firebox.
IMPORTANT: Glass must be allowed to
warm slowly and evenly. 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 fire
back from doors and never allow flames to
contact 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.
WARNING: When using a dec-
orative vented gas log, damper
must be removed or permanently
locked in fully open position and
glass doors must be in fully open
position.
Cleaning Glass
Clean glass with any commercial glass
cleaner or soap and water. Do not use any
abrasive material to clean glass. Do not clean
glass with any cool water if glass is still hot
from 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.
