VC4G & VC6G SERIES FULL SIZE CONVECTION OVENS - REMOVAL AND REPLACEMENT OF PARTS
NOTE: The fan must be installed so air is pulled from
the rear of the oven and blown into the control area.
The arrow on the fan body indicates "air flow" direction
and should be pointing toward the controls.
NOTE: Ensure fan is seated "squarely" against the air
tube and the oven bottom.
NOTE: The air deflector should be angled upwards
at approximately 30 degrees to properly direct the air
flow.
