OPERATION
THERMOSTATIC CONTROL OPERATION
The thermostat used on this heater senses the room
temperature. At times the room may exceed the set
temperature. If so, the burner will shut off. The burner will
cycle back on when room temperature drops below the set
temperature. The control knob can be set to any comfort level
between “HIGH” (5) and “LOW”(1)
(see Fig. 19)
.
INSPECTING BURNERS
Check pilot flame pattern daily when in use and at least
yearly by a qualified service agency.
PILOT FLAME PATTERN
Fig. 20
shows a correct pilot flame pattern.
Fig. 21
shows an
incorrect pilot flame pattern. The incorrect pilot flame is not
touching the thermocouple. This will cause the thermocouple
to cool, which shuts the heater off. If pilot flame pattern is
incorrect: turn heater off
(see “To Turn Off Gas to Appliance” on page 21)
(see Troubleshooting pages 25 through 27.)

If yellow tipping occurs, your heater could produce increased levels of
carbon monoxide. If burner flame shows yellow tipping, follow instructions under
“Burner Flame Pattern” on page 21.
Notice:
Do not mistake orange flames with yellow tipping. Dirt or other fine particles
enter the heater and burn causing brief patches of orange flame.
