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 properly
installed and maintained venting system or tampering
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
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 particular
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.
