- check pressure readings:

Inlet pressure can be checked by turning screw (A) counter-clockwise 2 or 3 turns and then placing pressure gauge tubing over the test point. Gauge should read 7” (minimum 4.5”) water column for natural gas or 13” (11” minimum) water column for propane. Check that main burner is operating on “HI”.

Outlet pressure can be checked the same as above using screw (B). Gauge should read 3.5” water column for natural gas or 10” water col- umn for propane. Check that main burner is operating on “HI”.

AFTER TAKING PRESSURE READINGS, BE SURE TO TURN SCREWS CLOCKWISE FIRMLY TO RESEAL. DO NOT OVER- TORQUE.
