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 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: Never install the
fireplace
• in a bedroom or bathroom
• in a recreational vehicle
• where curtains, furniture,
clothing or other flammable
objects are less than 42 inches
from the front, top or sides of
the fireplace
• 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
fireplace 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 spacers are integrally attached. 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 Fire
-
place Installation, page 21).
IMPORTANT: Vent-free heaters add moisture to
the air. Although this is beneficial, installing fire
-
place in rooms without enough ventilation air may
cause mildew to form from too much moisture. See
Air for Combustion and Ventilation
, page 6.
IMPORTANT: Make sure the fireplace is level.
If fireplace is not level, log set will not work
properly.
CHECK GAS TYPE
Use the correct gas type (natural or propane/LP)
for your unit. If your gas supply is not correct, do
not install fireplace. Call dealer where you bought
fireplace for proper type fireplace.
