Before fi nishing in the appliance test the operation using the remote control, cycling it through all of its different
modes, see "OPERATION" section. Once fi nished in, access to the control components can only be done
through the inside of the appliance.
NOTE: Control module ON/OFF switch should always be in the "ON" position. If for any reason the
module is turned "OFF", the components plugged into the module won't have power.

10.4 VENTURI ADJUSTMENT

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!

10.5 FLAME CHARACTERISTICS

It's important to periodically perform a visual check of the pilot and burner fl ames. Compare them to the
illustration provided. If any fl ames appear abnormal call a service person.
