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
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 a synthetic scrub pad (such as
Scotch-Brite™) can be used to remove the paint from the pilot hood, electrode and flame sensor.

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.
12.3
restricting vertical vents
Vertical installations may display a very active fl ame. If this appearance is not desirable, the vent exit must be
restricted using a restrictor vent kit. Refer to the "replacement parts" section of the owner's manual for the
appropriate kit. This will reduce the velocity of the exhaust gases, slowing down the fl ame pattern and creating a
more traditional gentle fl ame appearance. Specifi c instructions are included with the kit.
note:
If the appliance has been reduced to 4/7" venting only, use an RP4 to restrict vertical venting.
