ADJUSTMENTS
VENTURI ADJUSTMENT
To access the air shutter, remove the two screws securing
the burner. After making adjustments replace the burner
ensuring that the venturi tube fits over the orifice and replace
the screws.
Air shutter have been factory set open according to the
chart below:
These settings are for (maximum) horizontal termination.
NG
1/32”
P
1/16”
Adjustments may be required depending on fuel type,
vent configuration and altitudes.
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 the established.
Air shutter adjustment must be done by a
qualified installer!

It is important to periodically perform a visual check of the
pilot and burner flames. Compare them to the illustrations
provided.
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 OVERTORQUE.
