Burner flame characteristics
Start the furnace and let it operate at least ten minutes.
Observe the flame from the Sight Window. The flame should
turn to blue color with scattered dots of yellow color within 5
seconds of ignition. Limit your movements near the furnace a
few more minutes before making your final observations. The
flame may look yellow due to dust particles in the room air.
The flame should change to a nice blue color with firm inner
and secondary cones. An occasional flash of orange might
be seen as dust particles burn in the flame. This is normal. No
burner adjustment is provided, or is necessary. (Figure 18).
Normal appearance
Natural Gas:
1. Inner cone–blue in color–3/8 to 5/8-inches above ports.
2. Secondary inner cone–light blue in color–1 to 2-inches
above ports.
3. Total flame–from blue in color to nearly invisible–
approximately 6-inches above ports.
Abnormal appearance
Lazy Flame:
Long, soft yellow cones moving around in the combustion
chamber lifting from ports (insufficient air).
Extremely Fast Flame:
Flame will not hold to ports–entire cone sections blow off
from noisy ports (too much pressure).
WARNING: If flame appears abnormal, contact the gas
company or a qualified service technician immediately.
