PRODUCT FEATURES
OpERATION
This heater is clean burning. It requires no outside

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-thermostat operation only).
AppLICATION
These multisided logs are designed to be equally
beautiful when viewed from any angle. They
are designed specifically for use in see-through,
peninsula, and island fireboxes with multiple
openings. You may also install this log heater in
a standard firebox.

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

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 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.
