PILOT BURNER ADJUSTMENT

Adjust the pilot screw to provide properly sized fl ame. Turn in a
clockwise direction to reduce the gas fl ow.
Check Pressure Readings: (Fig. 71)
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 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
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 OVER-
TORQUE.
Leak test with a soap and water solution.

ADJUSTMENTS

It is important to peri-
odically perform a visual
check of the pilot and
burner fl ames. Compare
them to the illustration
below.

Closing the air shutter will cause a
more yellow fl ame, but can lead to
carboning. Opening the air shutter
will cause a more blue fl ame, but can
cause fl ame lifting from the burner
ports. The flame may not appear
yellow immediately; allow 15 to 30
minutes for the fi nal fl ame colour to be established.
