control. It closes if pilot goes out. Each individual control
must be operating correctly before any gas can pass
to burners. Any one control can hold gas supply from
burner regardless of demand of any other control.
SAFETY PILOT
Safety Pilot prevents fl ow of gas to burner if pilot goes
out, or will not ignite.

after placing boiler in operation.

main burners fi ring, disconnect the thermocouple
from the gas valve. The gas valve should
immediately shut off main burners and the pilot.
