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.

RESTRICTING VERTICAL VENTS - MODEL GDS28
Vertical installations may display a very active fl ame. If this appearance is not desirable, the vent exit must be
restricted using the restrictor vent kit, GDSRP-KT. This will reduce the velocity of the exhaust gases, slowing
down the fl ame pattern and creating a more traditional gentle appearance. Specifi c instructions are included
with the kit.
