VENTURI ADJUSTMENT

To access the venturi, remove the screw securing each
burner to the burner pan; slide to the right, lift up and out.
Natural gas and propane models have air shutters set at
3
/ (.188) inch open on the front burner. The rear burner air
16
shutter opening is set at ½ (.500) inch open. 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.
