Flame Picture Adjustment - Jøtul GF 500 DV IPI Installation And Operation Instructions Manual

Flame Appearance / Air Shutter
Adjustment
The GF 500 DV IPI gas stove is shipped from the factory
equipped to burn Natural gas and the air inlet shutters
have been set to provide optimal combustion efficiency
under a variety of venting configurations. The air shutters
may be adjusted, however, to accommodate the conditions
of your individual installation and to provide the best
flame picture. Other installation related variables can also
affect the flame picture.
Too large an air setting - the appliance will generate a
flame that is blue and transparent, or an "anemic" flame.
Too small an air setting - the appliance will generate
very long yellow flames resulting in soot. Sooting
produces black deposits on the logs, on the inside walls of
the appliance, and potentially on the exterior termination
cap. Sooting is caused by incomplete combustion in the
flames and lack of combustion air entering the air shutter
opening.

WARNING: AIR SHUTTER ADJUSTMENTS SHOULD ONLY
BE PERFORMED BY A QUALIFIED PROFESSIONAL SERVICE
TECHNICIAN.
To adjust the air shutters:
1. Reach under the stove and loosen the wingnuts. The
RIGHT shutter controls the REAR Burner. The LEFT
shutter controls the FRONT Burner. See fig. 50. Slide the
wing nut studs forward toward yourself to open the air
shutters and back to provide less air. Before making any
adjustments, start at the factory shutter settings:
• Natural Gas - open 1/16" (1.5 mm)
• Propane - open 1/8" (3 mm)
2. Allow the stove to burn for 30 minutes on the HIGH
setting, observing the flame continuously. If the flame
appears weak, slow, or sooty, increase the air shutter
opening in 1/16" increments until the desired flame
picture is achieved.
3. Tighten the wing nuts to secure each shutter at the
desired setting.
