VENTURI ADJUSTMENT
Remove the 2 screws securing the control panel plate. To
access the venturi, remove the air housing cover plate, held
on with 2 screws. 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. Re-secure the control
panel plate.

Air shutter adjustment must only be
