VENT SAFETY SHUTOFF SYSTEM
This heater must be properly connected to a venting system. This
heater is equipped with a vent safety shutoff system.
Warning:
Operation of this heater, when not connected to a prop-
erly installed and maintained venting system or tamper-
ing with the vent safety shutoff system, can result in
carbon monoxide (CO) poisoning and possible death.
This appliance needs fresh air for safe operation and must be
installed so there are provisions for adequate combustion and
ventilation air.
This room heater is equipped with a vent safety switch. The
vent safety switch will cause gas flow to the pilot to “shut off”
due to improper venting or a blocked flue.
If the vent safety switch continues to “shut off” the gas flow to
the pilot a qualified service person must be contacted to
inspect for improper venting, blockage in the vent pipe or the
vent safety switch for being defective.

DRAFT DIVERTER CAN BE EITHER A VERTICAL
VENT OR HORIZONTAL VENT

THERMOSTAT OPERATION
Thermostat Operation
To turn on burner, rotate dial knob toward setting number 7. To
shut down burner, rotate dial knob toward number 1.
The dial numbers 1 through 7 correspond to 50° (10°C) through
90°F (32°C). This is the temperature at the bulb thermostat not the
room temperature. The owner is advised to determine the particu-
lar heat setting that is desired for comfort, as heating requirements
are different for every owner.
Attention: If no heat is desired, turn the gas control knob to the
PILOT position.
