OPERATION
This appliance is clean burning. It requires
no outside venting. There is no heat loss out
a vent or up a chimney. Heat is generated by
both realistic flames and glowing coals. This
appliance is designed for vent-free operation
with flue damper closed. It has been tested
and approved to the ANSI Z21.11.2 standard
for unvented appliances. State and local codes
in some areas prohibit the use of vent-free ap-
pliances. This appliance may also be operated
as a vented decorative (ANSI Z21.60) product
by opening the flue damper.
AIR FOR COMBUSTION AND VENTILATION
WARNING: This heater shall not
be installed in a room or space un-
less the required volume of indoor
combustion air is provided by the
method described in the National
Fuel Gas Code, ANSI Z223.1/NFPA
54, the International Fuel Gas Code,
or applicable local codes. Read the
following instructions to ensure
proper fresh air for this and other fuel-
burning appliances in your home.
Today's homes are built more energy efficient
than ever. New materials, increased insulation
and new construction methods help reduce
heat loss in homes. Homeowners apply
weather strip and caulk around windows and
doors to keep the cold air out and the warm air
in. During heating months, homeowners want
their homes as airtight as possible.
While it is good to make your home energy
efficient, your home needs to breathe. Fresh
air must enter your home. All fuel-burning ap-
pliances need fresh air for proper combustion
and ventilation.
Exhaust fans, some fireplaces, clothes dryers
and some fuel-burning appliances draw air
from the house to operate. You must provide
adequate fresh air for these appliances. That
will ensure proper venting of vented fuel-burning
appliances.

SAFETY DEVICE
This appliance has a pilot with an Oxygen
Depletion Sensing (ODS) safety shutoff
system. The ODS/pilot is a required feature
for vent-free room appliances. The ODS/pilot
shuts off the appliance if there is not enough
fresh air.
ELECTRONIC IGNITION SYSTEM
This appliance has an electronic igniter to light
appliance fuel supply.
following ventilation classifications:
1. Unusually Tight Construction
2. Unconfined Space
3. Confined Space
The information on Pages 6 through 8 will
help you classify your space and provide
adequate ventilation.
Unusually Tight Construction
The air that leaks around doors and windows
may provide enough fresh air for combustion
and ventilation. However, in buildings of un-
usually tight construction, you must provide
additional fresh air.
Unusually tight construction is defined as
construction where:
a. walls and ceilings exposed to the out-
side atmosphere have a continuous
water vapor retarder with a rating of
one perm (6 x 10
less with openings gasketed or sealed
and
b. weather stripping has been added on
openable windows and doors and
c. caulking or sealants are applied to
areas such as joints around window
and door frames, between sole plates
and floors, between wall-ceiling joints,
between wall panels, at penetrations
for plumbing, electrical and gas lines
and at other openings.
If your home meets all three criteria above,
you must provide additional fresh air. See
Ventilation Air From Outdoors, Page 8.
If your home does not meet all three criteria
above, proceed to Determining Fresh-Air Flow
For Heater Location, Page 7.
