Observing the Flame Length:
Visually inspect the flame length through the observation
port. Refer to Figure 6C for an illustration of the desired
flame length. The flame should extend no more than
one-half of the way down the combustion chamber.
WARNING:
The observation port gets hot as the burner
fires. To avoid personal injury, always wear heavy work
gloves and safety glasses when opening the port and viewing the
flame.
CAUTION

Starting the Burner (continued)
4.
Check the flame length after the burner has fired for 15 minutes.
5.
Tighten the locking nuts on the air regulator.
6.
Fine Tuning the Combustion Air Band for CB-3500 Furnaces:
NOTE:
The initial setting of the combustion air band may require additional adjustment.
• Refer to Figure 6A to identify the combustion air band location on the burner.
• Observe the flame. The flame should be yellow-white with sharp tips and no "sparkles."
• If the flame is orange in color or the flame length is too long, the oil you are burning
requires MORE combustion air. OPEN the air band 1/8" to 1/4", and re-check the flame
for the proper characteristics.
• Re-check the flame after five minutes. You should see a yellow-white flame with sharp
tips and no "sparkles", and the flame should extend half of the way down the combustion
chamber.
Correct Maximum Flame Adjustment
(Proper Oil and Air Pressure with correct supply of
Combustion Air):
• Flame goes half of the way down the
combustion chamber.
• Flame does not touch back or walls of
combustion chamber.
Incorrect Flame Adjustment
(Not Enough Combustion Air):
• Flame must not touch back or walls of
combustion chamber.
•
Increase combustion air by opening the
air band on the side of the burner.
Incorrect Flame Adjustment
(Air Pressure Too High):
• Ensure proper air pressure setting.
