INSTALLATION
NOTICE: This heater is intended
for use as supplemental heat.
Use this heater along with your
primary heating system. Do not
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: Make sure the
selector switch is in the OFF po-
sition before installing heater
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 front -
for side clearances see Figure
8, page 9
• 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 ma-
terial can be placed directly against any exterior
surface on the rear, sides or top of your fireplace,
except where standoff spacers are integrally at-
tached. If standoff spacers are attached to your
fireplace, 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
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.

ventilation Air From Outdoors
Provide extra fresh air by using ventilation
grills or ducts. You must provide two perma-
nent openings: one within 1" 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 thermo-
stat-controlled power vent. Heated air entering
the attic will activate the power vent.
