AIR FOR COMBUSTION AND VENTILATION
Ventilation Air From Outdoors
Provide extra fresh air by using ventilation
grills or ducts. You must provide two perma-
nent 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, 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 thermo-
stat-controlled power vent. Heated air entering
the attic will activate the power vent.
NOTICE: This heater is intended
for use as supplemental heat.
Use this heater along with your
primary heating system. Do not
f i r e - p a r t s . c o m
install this heater as your pri-
mary 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 ser-
vice person must install fire-
place. Follow all local codes.
WARNING: Never install the
fireplace
• in a bedroom or bathroom
• in a recreational vehicle
• where curtains, furniture,
clothing, or other flammable
objects are less than 36" from
the front and 42" from the top
of fireplace. For side clear-
ances see Figure 8, page 10
• in high traffic areas
• in windy or drafty areas

CAUTION: This fireplace cre-
ates warm air currents. These
currents move heat to wall sur-
faces next to fireplace. Installing
fireplace next to vinyl or cloth
wall coverings or operating
heater where impurities (such
as, but not limited, to tobacco
smoke, aromatic candles, clean-
ing fluids, oil or kerosene lamps,
etc.) in the air exist, may discolor
walls or cause odors.
Note: Your fireplace 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 fireplace, except where standoff spac-
ers are integrally attached. Where standoff
spacers are attached to your fireplace,
combustible material (studs and wall board)
may be place on top and above the top of
the standoffs.
Use the dimensions shown for rough openings
to create the easiest installation. See Built-In
Fireplace Installation, page 11.
IMPORTANT: Vent-free heaters add moisture
to the air. Although this is beneficial, installing
fireplace in rooms without enough ventilation
air may cause mildew to form from too much
moisture. See Air for Combustion and Ventila-
tion, page 6.
IMPORTANT: Make sure the fireplace is level. If
fireplace is not level, log set will not work properly.
