sion, electrical shock and carbon
monoxide poisoning.
DANGER: Carbon monoxide

Sensing (ODS) safety shutoff system. The ODS/
pilot is a required feature for vent-free room heat-
ers. The ODS/pilot system shuts off the fireplace
if there is not enough fresh air.

matically light the pilot and adjust the burner flame
height at the push of a button.

sembly with glowing LEDʼs. The wall switch per-
forms the same functions as the wireless hand-held
