VENTURI ADJUSTMENT
Remove the 2 screws securing the control panel plate. To
access the venturi, remove the 2 screws securing the air
housing cover plate. Take care not to damage the gasket.
Natural gas and propane models have air shutters set fully
open. Closing the air shutter will cause a more yellow flame,
but can lead to carboning. The flame may not appear yel-
low immediately; allow 15 to 30 minutes for the final flame
colour to be established. After making adjustments re-
place the gasket and cover plate.
Air shutter adjustment must only be
done by a qualified gas installer!
