Notice: The settings in this chart are for reference only. The actual conditions at the installation may require further
adjustment by the fully qualifi ed and experienced start-up technician.
Notice: The light-off rate must not be set below the low fi re recommendation. Lower rates will lengthen the time it takes for
gas to get to the burner head and may cause ignition failures.

The shutter and band both
control the amount of fl ow area
control the amount of fl ow area
available for air inlet to the burner. The greater their
combined fl ow area, the higher the fi ring rate. The
primary differences between the two are their ease of
adjustment and their total airfl ow area. The shutter
turns more easily and has a smaller net fl ow area. As a
result we have found the shutter to be better suited for
low rate adjustments, and the band better suited for high
rate adjustments. We recommend that at low rates the
band be left completely closed until the shutter has been
fully opened, and that for higher rates the shutter is left
completely open as the band is opened.
