10.1 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:
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 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.
Leak test with a soap and water solution.

10.2 VENTURI ADJUSTMENT
This appliance has an air shutter that has been factory set open according
to the chart below:
Regardless of venturi orientation, closing the air shutter will cause a more
yellow flame, but can lead to carboning. Opening the air shutter will cause a
more blue flame, but can cause flame lifting from the burner ports. The
flame may not appear yellow immediately; allow 15 to 30 minutes for the
final flame colour to be established.
AIR SHUTTER ADJUSTMENT MUST ONLY BE DONE BY A QUALIFIED
INSTALLER!
