12.0 adjustment adjustment
EN
12.1 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 pressure with main burner 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
pressure with main burner operating on "HI".
After taking pressure readings, be sure to turn screws
clockwise fi rmly 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 a
synthetic scrub pad (such as Scotch-Brite™) can be used to remove the paint from the pilot hood, electrode
and fl ame sensor.

12.2 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 carbonization. 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.
note:
It is important that the orifice is securely inserted into the venturi.
