venting. There is no heat loss out a vent or up a
chimney. Heat is generated by both realistic flames
and glowing coals. 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
(ANSI Z21.60) product by opening the flue damper
(Non-Thermostat Models Only).

heaters. The ODS/pilot shuts off the heater if there
is not enough fresh air.
