PILOT ADJUSTMENT
Locate the pilot adjustment screw on the valve. The pilot
flame should surround at least the top 3/8” of the powerpile
(pilot generator) or thermocouple (see below). The pilot is
unregulated so it will be operating at inlet line pressure (Max.
7” w.c. for natural gas and 11” w.c. for propane). To decrease
the pilot flame, turn the screw clockwise (approximately seven
to nine full turns to bottom of pilot light channel) until you
produce sufficient flame at the minimum noise level.
