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.
