set the thermostat to the oFF position. see
Figure 5. If the manual gas control knob
on the gas valve is not in the oFF position,
partially depress the knob and rotate to the
oFF position. see Figure 6.
Wait 5 minutes to allow gas that may have
accumulated in the main burner to escape
(especially important after installation).
Turn the manual gas control knob to the PIloT position.
Depress the manual gas control knob. Using a match, light the
pilot light. see Figure 6. Hold the knob down for approximately
30 seconds to allow any air in gas lines to pass through pilot and,
once the pilot is lit, allow the thermocouple to heat up enough to
activate the safety valve in an open position.

intermittent use
Appliances that are used seasonally should be checked before
shutdown and again before the next use.
Dusty, wet or corrosive environment. since these environments
can cause the gas control to deteriorate more rapidly, the system
should be checked more often.

a. It does not perform properly on checkout or trouble-
shooting.
b. The gas control knob is hard to turn or push down, or it
fails to pop back up when released.
