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

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!
