4. Wait five (5) minutes to clear out any gas. Then smell
for gas, including near the floor. If you smell gas, STOP!
Follow "B" in the safety information above. If you do not
smell gas, go to the next step.
5. Turn counterclockwise
not turn then slightly depress and turn. Once knob is in
PILOT/ IGN depress for five (10) seconds.
Note: The first time that the heater is operated after
connecting the gas supply, the control knob should be
depressed for about 30 seconds. This will allow air to bleed
from the gas system.
6. With control knob pressed in, push down and release
the ignition button. This will light pilot. If needed keep
pressing igniter button until pilot lights. If pilot does
not stay lit, refer to Troubleshooting, pages 12-13. Also,
contact a qualified service person or gas supplier for
repairs.
If control knob does not pop up when released, contact a
qualified service person or gas supplier for repairs.
7. When the pilot is lit, turn the control knob
counterclockwise to heating level. The main burner
should light.
8. To select the desired heat level, turn the temperature
setting knob to desired comfort setting from 1 to 5.
CAUTION: Do not try to adjust heating level by using
equipment shutoff valve.
THERMOSTAT CONTROL OPERATION
The thermostatic control used modulates the flame size as
the temperature gets closer to set point, then it turns off
the burner upon reaching temperature.
The burner will cycle back on when room temperature
drops below the set temperature. The control knob can be
set to any heat level between 1 and 5.

INSPECTING BURNER
Check pilot flame pattern and burner flame pattern often.
PILOT FLAME PATTERN
Figure 15 show a correct pilot flame pattern and also shows
an incorrect pilot flame pattern. The incorrect pilot flame
pattern is not touching thermocouple. This will cause the
thermocouple to cool. When the thermocouple cools, the
heater will shut down. If pilot flame pattern is incorrect, as
shown in Figure 15:
•
Turn heater off (see To Turn OFF Gas to Appliance,
page 10)
•
