AIR FOR COMBUSTION AND
VENTILATION
Continued
Ventilation Air From Outdoors
Provide extra fresh air by using ventilation grills or ducts. You must
provide two permanent openings: one within 12" of the ceiling and
one within 12" of the floor. Connect these items directly to the
outdoors or spaces open to the outdoors. These spaces include attics
and crawl spaces. Follow the National Fuel Gas Code ANSI Z223.1/
NFPA 54, Section 5.3, Air for Combustion and Ventilation for
required size of ventilation grills or ducts.
IMPORTANT: Do not provide openings for inlet or outlet air into
attic if attic has a thermostat-controlled power vent. Heated air
entering the attic will activate the power vent.

INSTALLATION
NOTICE: This heater is intended for use as supple-
mental heat. Use this heater along with your primary
heating system. Do not install this heater as your
primary heat source. If you have a central heating
system, you may run system's circulating blower
while using heater. This will help circulate the heat
throughout the house. In the event of a power outage,
you can use this heater as your primary heat source.
WARNING: A qualified service person must in-
stall firebox. Follow all local codes.

WARNING: Never install the firebox
• in a bedroom or bathroom
• in a recreational vehicle
• where curtains, furniture, clothing, or other flam-
mable objects are less than 42 inches from the
front, top, or sides of the firebox
• in high traffic areas
• in windy or drafty areas
CAUTION: Log heaters installed in this firebox
create warm air currents. These currents move heat
to wall surfaces next to firebox. Installing firebox next
to vinyl or cloth wall coverings or operating firebox
where impurities (such as, but not limited to, tobacco
smoke, aromatic candles, cleaning fluids, oil or kero-
sene lamps, etc.) in the air exist, may discolor walls
or cause odors.
IMPORTANT: Vent-free gas log heaters add moisture to the air.
Although this is beneficial, installing firebox in rooms without
enough ventilation air may cause mildew to form from too much
moisture. See Air for Combustion and Ventilation, pages 4 through 6.
IMPORTANT: Make sure the firebox is level. If firebox is not level,
log set will not work properly.
Note : Your Comfort Glow firebox is designed to be used in zero
clearance installations. Wall or framing material can be placed
directly against any exterior surface on the rear, sides, or top of your
firebox, except where standoff spacers are integrally attached. If
standoff spacers are attached to your firebox, these spacers can be
placed directly against wall or framing materials.
Use the dimensions shown for rough openings to create the easiest
installation (see Built-In Firebox Installation, page 10).
