ADJUSTMENT

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 as described on the chart
below. Check that main burner is operating on "HI".
Outlet pressure can be checked the same as above using
screw (B). Gauge should read as described on the chart
below. 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.
Prior to pilot adjustment, ensure that the pilot assembly
has not been painted. If overspray or painting of the pilot
assembly has occurred remove the paint from the pilot
assembly, or replace. Fine emery
cloth or sandpaper can be used to
remove the paint from the pilot hood,
electrode and fl ame sensor.

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!
