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 decorative product (ANSI
Z21.60) by opening flue damper (non-thermo-
stat operation only).

REMOTE CONTROL ACCESSORIES

There are four optional remote controls that
can be purchased separately for this log
heater:
• wall switch
• wall thermostat
• hand-held ON/OFF remote
• hand-held thermostat remote

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 insula-
tion, 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
efficient, your home needs to breathe. Fresh

decorative listing is required.
air must enter your home. All fuel-burning ap-
pliances 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, SAir 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
