-remove blockage. In really cold conditions, ice buildup may occur on the terminal and should be removed as required.

-refer to Figure 34 to ensure correct location of storm collars. (vertical vent)

-check pressure readings:

Inlet pressure can be checked by turning screw (A) counter-clock- wise 2 or 3 turns and then placing pressure gauge tubing over the test point. Gauge should read 8" (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 column 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 OVERTORQUE.

Pilot goes out when the gas knob is released.

The gas valve has an interlock de- vice which will not allow the pilot burner to be lit until the thermo-
