AIR FOR COMBUSTION AND
VENTILATION
Today’s homes are built more energy efficient than ever. New mate-
rials, 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 efficient, 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.
WARNING: This heater shall not be installed in a
confined space or unusually tight construction un-
less provisions are provided for adequate combus-
tion and ventilation air. Read the following instruc-
tions to insure proper fresh air for this and other
fuel-burning appliances in your home.

PRODUCT FEATURES
OPERATION
This vent-free fireplace 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. When used without the blower, the
fireplace requires no electricity making it ideal for emergency backup
heat. This heater is designed for vent-free operation. 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.
SAFETY DEVICE
This fireplace has a pilot with an Oxygen Depletion Sensing (ODS)
safety shutoff system. The ODS/pilot is a required feature for vent-
free room heaters. The ODS/pilot system shuts off the fireplace if
there is not enough fresh air.
PIEZO IGNITION SYSTEM
This fireplace has a piezo ignitor. This system requires no matches,
batteries, or other sources to light fireplace.
