Burner Ignition - Jenn-Air JGD8348CDP Installation Instructions Manual

Check Operation of Surface Burners
Push in and turn the surface burners control knobs to light.
The surface burner flame should light within 4 seconds. The first
time a surface burner is lighted it may take longer that 4 seconds
to light because of air in the gas line.
Check the flame on "HIGH" for a blue color. It should be clean
and soft in character. No yellow tip, blowing or lifting of flame
should occur. Occasional orange flashes are normal and reflect
different elements in the air or gas.
After verifying the proper burner operation, turn the control knobs
to "OFF."
If burners do not light properly:
Turn surface burner control knob to the "OFF" position.
Check that the power supply cord is plugged in and the
circuit breaker has not tripped or the fuse blown.
Check that the gas shutoff valves are set to the "open"
position.
Check that burner caps are properly positioned on burner
bases.
Recheck operation of surface burners. If a burner does not light
at this point, contact your dealer or authorized service company
for assistance.
Adjust Flame Height
Adjust the height of top burner flames. The cooktop "low" burner
flame should be a steady blue flame approximately ¼" (0.64 cm)

Adjust Air Shutter
This appliance is shipped from the factory with the air shutters
adjusted for use with Natural Gas. If further adjustment is
necessary, or to reset for use with LP, adjust the air shutters using
the following instructions.
Grill Burner and Surface Burner Cartridge Air Shutters
The left hand air shutter controls the rear half of the burner. The
right hand shutter controls the front half. Access to air shutters on
the surface burner cartridge may be found through openings on
the bottom of the cartridge housing.
Slide air shutters backward or forward to increase or decrease
the size of the air opening. Air shutters fit snugly, so a screwdriver
blade or needle nose pliers may be required to make this
adjustment. (See the following illustration.)
A. Air opening
B. Air shutter
C. Insert screwdriver blade in slot and twist with
slight pressure to allow air shutter to slide easily
Observe change in flame appearance as the air shutter is moved.
Adjustment is satisfactory when a clearly defined, even blue
flame results at the high flame setting. The snug fit of the air
shutter assures it will remain positioned correctly.
