The valve regulator controls the burner pressure which should be checked at the pressure
test point.
Turn captured screw counter clockwise two or three turns and then place tubing to pres-
sure gauge over test point. (Use test point “A” closest to gas inlet). After taking pressure
reading, be sure and turn captured screw clockwise firmly to reseal. Do not over torque.
Check for gas leaks.
