CAUTION: Do not remove the
data plates from the grate as-
sembly. The data plates contain
important warranty and safety
information.
1. Remove logs and heater base assembly
from carton.
OPERATION
This heater 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
heater is designed for vent-free operation
with flue damper closed. It has been tested
and approved to ANSI Z21.11.2 standard
for unvented heaters. State and local codes
in some areas prohibit the use of vent-free
heaters. This heater may also be operated
as a vented decorative (ANSI Z21.60) product
by opening the flue damper (Remote-Ready
Models Only).

AIR FOR COMBUSTION AND VENTILATION

WARNING: This heater shall
not be installed in a room or space
unless the required volume of in-
door 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 lo-
cal codes. Read the following in-
structions to insure 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. Home owners weather
strip and caulk around windows and doors
to keep the cold air out and the warm air in.
During heating months, home owners want
their homes as airtight as possible.
While it is good to make your home energy effi-
cient, your home needs to breathe. Fresh air must
enter your home. All fuel-burning appliances need
fresh air for proper combustion and ventilation.

Note: Do not pick up heater base as-
sembly by burners. This could damage
heater. Always handle base assembly by
the sides of assembly.
2. Remove all protective packaging applied
to logs and heater for shipment.
3. Check all items for any shipping damage.
If damaged, promptly inform dealer where
you bought heater.
SAFETY DEVICE
This heater has a pilot with an Oxygen Deple-
tion Sensing (ODS) safety shutoff system. The
ODS/pilot is a required feature for vent-free
room heaters. The ODS/pilot shuts off the
heater if there is not enough fresh air.
PIEZO IGNITION SYSTEM
This heater has a piezo ignitor. This system re-
quires no matches, batteries or other sources
to light heater.
Exhaust fans, fireplaces, clothes dryers and
fuel burning appliances draw air from the house
to operate. You must provide adequate fresh
air for these appliances. This will insure proper
venting of vented fuel-burning appliances.
PROVIDING ADEQUATE
VENTILATION
The following are excerpts from National Fuel
Gas Code. ANSI Z223.1/NFPA 54, Air for
Combustion and Ventilation.
All spaces in homes fall into one of the three
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.
