PRESSURE ADJUSTMENT
Adjust the pilot screw to provide properly sized flame. Turn in a
clockwise direction to reduce the gas flow.
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 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, TIGHTEN SCREWS
FIRMLY TO SEAL. DO NOT OVER TORQUE.

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.
