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 the inlet pressure while the 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.

AFTER TAKING PRESSURE READINGS, TIGHTEN SCREWS 

FIRMLY TO SEAL. DO NOT OVER TORQUE.

LEAK TEST.

ADJUSTMENTS

VENTURI ADJUSTMENT

Air shutter adjustment must be done by a qualified 

installer!

Air shutters have been factory set open according to the chart 

below:  

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.

 

Adjustment may be required depending on fuel type, vent con-

figuration and altitude.
