FLAME CHARACTERISTICS

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

RESTRICTING VERTICAL VENTS

Some vent confi gurations may display a very active
fl ame. If this appearance is not desirable, the vent exit
may be restricted using a restrictor plate. Bend the fl ap
up as shown to reduce the velocity of the exhaust gases,
slowing down the fl ame pattern and creating a more
traditional appearance.
