logs and heater for shipment.
3. Check all items for any shipping damage. If

PRODUCT FEATURES
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 realistic dancing,
yellow flames. 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 decora-
tive (ANSI Z21.60) product by opening the flue
damper (non-thermostat operation only).
SAFETY PILOT
This heater has a pilot with an Oxygen Depletion
Sensing (ODS) safety shutoff system. The ODS/
pilot is a required feature for vent-free room heat-
ers. 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.
AIR FOR COMBUSTION
AND VENTILATION
WARNING: This heater shall
not be installed in a confined
space or unusually tight con-
struction unless provisions are
provided for adequate combus-
tion and ventilation air. Read
the following instructions to in-
sure proper fresh air for this
and other fuel-burning appli-
ances 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.
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, Section 5.3, Air
for Combustion and Ventilation.
All spaces in homes fall into one of the three fol-
lowing ventilation classifications:
1. Unusually Tight Construction
2. Unconfined Space
3. Confined Space
The information on pages 5 through 7 will help
you classify your space and provide adequate
ventilation.
