VENTURI ADJUSTMENT

Air shutters have been factory set open according to the chart below:

 

AIR SHUTTER

 

 

NG

1/4"

LP

7/16"

These settings are for the maximum horizontal vent run.- Adjustment may be required depending on fuel type, vent configuration and altitude.

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 estab- lished.

Air shutter adjustment must only be done by a

qualified installer!
