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 ap-
proved to ANS Z21.11.2 standard for
unvented heaters. State and local codes in
some areas prohibit the use of vent-free
heaters. Non-thermostat models may also
be operated as a vented decorative (ANS
Z21.60) product by opening flue damper.

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 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
requires no matches, batteries, or other
sources to light heater.

 WARNING: Do not remove

the metal Data Plates from the
grate assembly. The Data Plates
contain important product
information.

1.

Remove logs and heater base assem-
bly from carton.

base assembly by grate.

2.

plied to logs and heater for shipment.

age. If damaged, promptly inform
