VERMICULITE

Sprinkle vermiculite around the charcoal embers.
NOTE: Vermiculite is not to be placed on the burner.

2.10 GLOWING EMBERS

Tear the embers into pieces and place along the front row of ports covering all of the burner area. Care should
be taken to shred the embers into thin, small irregular pieces as only the exposed edges of the fi bre hairs will
glow. The ember material will only glow when exposed to direct fl ame; however, care should be taken to not
block the burner ports.
Blocked burner ports can cause an incorrect fl ame pattern, carbon deposits and delayed ignition. Phazer™
logs glow when exposed to direct fl ame. Use only certifi ed "glowing embers" and Phazer™ logs available from
your Authorized dealer.

FLAME CHARACTERISTICS

It's important to periodically perform a visual check of the pilot and burner fl ames. Compare them to the illustra-
tions provided. If any fl ames appear abnormal call a service person.
3.2

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 color to be established.
AIR SHUTTER ADJUSTMENT MUST ONLY BE DONE BY A QUALIFIED
INSTALLER!
