Adjust the pilot screw to provide properly sized fl ame. Turn in a
clockwise direction to reduce the gas fl ow.
Inlet pressure can be checked by turning screw (A) counter-
clockwise until loosened 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 the inlet pressure while the 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.
AFTER TAKING PRESSURE READINGS, TIGHTEN SCREWS
FIRMLY TO SEAL. DO NOT OVER TORQUE.
LEAK TEST.

ADJUSTMENTS
VENTURI ADJUSTMENT
Air shutter adjustment must be done by a qualifi ed
installer!
Air shutters have been factory set open according to the chart
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 fl ame may not appear yellow immediately; allow 15 to 30
minutes for the fi nal fl ame colour to be established.
Adjustment may be required depending on fuel type, vent con-
fi guration and altitude.
