Install head positioning bar
1. The burner is supplied with up to seven calibrated bars that properly
positiontheheadintheairtube.Seethetablebelowforheadposition-
ing bars available.
2. The head positioning bars are stamped with a nozzle size range. Use a
positioning bar with the range that includes the nozzle size installed.
3. SeeFigure9.Removetheexistingbar(ifinstalled)andreplacewith
the correct one.
4. Store any remaining bars in the rearof the burner to allow future

Adjust air band (initial setting)
1. The burner pump pressure is factory set. The pump pressure is indi-
cated on a label affixed to the pump only if it is something other than
100 psi. The air band divisions match the nozzle size regardless of the
pump pressure setting. Loosen the lock screw and move the air band
untilthepointerslineupwiththesettingindicatedintheOEMSet-up
Tableortoasettingthatmatchesthenozzlesize(foraretrotburner).
Seegure10.
2. NOTE:Forhighaltitudeinstallationsabove2,000feet,increasethe
air supply setting 4% for each 1,000 feet above 2,000 feet above sea
level.
3. The burner is now adjusted to the approximate air band setting for the
nozzle size indicated. When you check combustion with instruments
during start-up or servicing, you may have to adjust the air band slightly
toachievethedesiredcombustionreadings.See“Adjustburnerusing
testinstruments,”page22.
