Flame Appearance -

Air Shutter Adjustment
The GF 600 DV II FIRELIGHT gas stove is shipped from
the factory equipped as a NATURAL GAS STOVE. If
the stove is converted for propane, it will be neces-
sary to adjust the air shutter on the burner tube to
achieve the proper gas/air mixture. The initial air
shutter settings are:
1/8" open for natural
5/16" open for propane
The air shutter can also help achieve the desired
flame appearance. Generally, flame appearance is a
matter of preference, however most people enjoy a
warm yellowish flame.
Air Shutter Too Open - the burner will generate
flames that are blue and transparent, or otherwise
weak looking.
Air Shutter Too Closed - the burner will generate
very long, stringy yellow flames which can result in
soot deposits on the logs, on the inside walls of the
appliance, and potentially on the exterior termina-
tion cap.
Sooting is caused by incomplete combustion in
the flames and lack of combustion air entering the
air shutter opening.
Adjust the Air Shutter: The shutter is adjusted
from under the stove. The adjustment stem is
secured by a wingnut and is located directly behind the
gas valve toward the rear of the stove. See fig. 29.
Loosen the wingnut and slide the shutter stem back
to open (more air) and forward to close.
Make air shutter adjustments in small incre-
ments and wait about 15 minutes to let the fire
settle in before making further adjustments. When
the optimal position has been found, tighten the
wingnut to secure the Shutter.
