8.0 ADJUSTMENT

8.1  VENTURI ADJUSTMENT

CARBON CAN BE DISTRIBUTED IN SURROUNDING LIVING AREA IF THE AIR SHUTTER IS 

IMPROPERLY ADJUSTED. 

!

WARNING

49.5

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!
