Inspecting Burners - Superior Fireplaces DRL4543TEP Assembly, Installation And Operation Instructions

Check pilot flame pattern and burner flame patterns often.
PILOT ASSEMBLY
The pilot assembly is factory preset for the proper flame. Alterations
may have occurred during shipping and handling. The pilot is located
on right hand side of burner.
The flame must envelope 1/4" of top of the Igniter/sensor and ground-
ing stem.
If your pilot assembly does not meet these requirements:
• Turn the adjustment screw marked PILOT clockwise to decrease or
counterclockwise to increase the flame to proper size (see Figure
48). Do not remove the adjustment screw.
• See Troubleshooting, Page 41
BURNER AND PILOT FLAME APPEARANCE AND SOOTING
The flame should be blue at the base, and yellow-orange in the body
of the flame. When the fireplace is first lit, the entire flame may be
blue and will gradually turn yellow-orange during the first 15 minutes
of operation. If the flame remains blue, or if the flame is orange with
evidence of sooting (black tip), the air shutter opening may need to
be adjusted.
If the air shutter opening is closed too far, sooting may develop.
Sooting is indicated by black puffs developing at the tips of very
long orange flames. Sooting results in black deposits forming on
the logs, fireplace inside surfaces, and on exterior surfaces adjacent
to the vent termination.
Sooting is caused by incomplete combustion in the flames and lack
of combustion air entering the air shutter opening. To achieve a
warm yellow-orange flame with an orange body that does not soot,
the shutter opening must be adjusted between these two extremes.
If burner flame pattern differs from that described:
• Turn fireplace off (see To Turn Off Gas to Appliance), Page 33
• See Troubleshooting, Page 41
