Starting The Burner - Saturn 125 Operator's Manual

Preparing the Burner for Startup (continued)
6. Initial Adjustment of the Combustion Air Band:
WARNING: The combustion air band must be properly adjusted to ensure that the burner
ignites and burns correctly. DO NOT attempt to start the burner with the combustion air band
wide open or completely closed. The burner may not ignite correctly. Failure to heed this warning may
result in a fire or explosion hazard.
• Refer to Figure 6A to locate the combustion air band.
• Rotate the combustion air band to adjust it to the appropriate initial slot opening as listed
in the following Initial Adjustment Charts. Use a ruler to accurately set the combustion air
band gap.
IMPORTANT NOTE: This initial setting of the combustion air band will allow you to start the burner.
You will fine tune the combustion air band further as described later in these instructions.
ATTENTION: The settings shown in the charts below are only initial adjustments. Final
adjustments must be done by inspecting the flame length according to the illustration
provided on the following page.
NOTE: The oil pressure is automatically adjusted by the metering pump.
