Starting the Burner (continued)
6.
Fine Tuning the Combustion Air Band:
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
recheck the flame for the proper characteristics.
• Recheck the flame after five minutes. You should see a yellow-white flame with sharp
tips and no "sparkles", and the flame should extend half the way down the combustion
chamber.
7.
Checking for a Smokeless Burn:
Check for a smokeless burn by observing the stack while the burner is running. If you see any
smoke, repeat the previous steps for setting the combustion air band and adjusting the air
regulator. After adjusting the combustion air band, re-check the flame length.
NOTE: Check for a smokeless burn periodically (as you do the flame length). Immediately
readjust the burner if you ever see smoke coming from the stack. Smoke indicates improper air/
fuel adjustment.
NOTE: When using instruments to adjust the burner for a smokeless burn, the following
readings should be achieved:
• Draft over fire should be -.02 inch w.c.
• Adjust for a smoke spot of a trace to 2
• Adjust for a CO2 reading of 8 to 10% or an O2 reading of 7 to 9%
• Cad cell reading below 500 ohms
Checking the Operation of the Blower Motor
NOTE: It is important to verify that the blower motor operates correctly to ensure that the fan limit
control is properly cycling the blower motor as described below. Also refer to Appendix A at the back of
the manual for additional pertinent information.
1. Start the burner and adjust it as described previously in this section.
2. The blower motor will not start until the burner has been running for 5 to 15 minutes to heat up
the combustion chamber and heat exchanger. At this point, the fan fan switch will activate the
blower motor.
3. Once the blower motor has activated, turn the burner off by turning the wall thermostat to OFF.
4. With the burner off, the blower motor should continue to run for 5 to 10 minutes until the
combustion chamber is cooled down. The fan switch will then shut off the motor.
WARNING: If the blower motor does not operate as described, immediately shut down
your furnace to avoid potential equipment damage and/or fire hazard. Contact your local Clean
Burn Distributor immediately.
