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: Do not oper-
ate an unvented gas log set in
this fireplace with the chimney
removed.
WARNING: If the fireplace
has been used for wood burning,
the firebox and chimney must be
cleaned of soot, creosote and
ashes by a qualified chimney
cleaner. Creosote will ignite if
heavily heated.

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 the fire. To remove doors, refer to instruc-
tions included with glass door kit.
WARNING: When using a
decorative vented gas log, the
damper must be removed or per-
manently locked in the fully open
position and the glass doors must
be in the fully open position.
Note: An appropriate DESA Heating, LLC
hood (see Replacement and Accessory Parts,
page 15) must be installed when using an
unvented gas log set.

GLASS DOORS
Bi-fold glass doors are optional with this
fireplace. Check with your local distributor
for availability.
To install glass doors, refer to installation
instructions that are included with kit. When
fireplace is in operation, doors must be fully
open or fully closed position only or a fire haz-
ard may be created (see Figure 31).
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. Excessive
heat within the fireplace can result if too large
a fire is built or if combustion air gate is not
completely open.
The following tips should be followed to as-
sure that both the fireplace 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 gener-
ate. 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.
