The burner is adjusted at the factory to provide typical
positions of the fuel, air and FGR valves. There may be
signicant differences for your specic application, based
on different altitudes, temperatures, fuels and furnace
conditions. The burner must be adjusted to meet these
specic application conditions. In addition, several checks
and adjustments are required prior to startup. This sec-
tion covers these preliminary checks and adjustments.

Section E - Preliminary Adjustments
1. Visual Inspection
The shipment and installation of the burner can result in
loose connections, bent arms and other changes. The
burner should be visually inspected for any unusual
conditions before operating.
• All wiring connections are tight. Test pulls on wire show
them to be tight.
• All fuel lines are tight.
• Burner is mounted to vessel and oor, with all bolts
secured.
• The linkage and cams are tight.
• The linkages, cams and valve actuators are aligned
and have not been bent during installation.
• The air damper, FGR line and control valves are tight.
• The oil lines are tight.
• Check the valve positions to insure they are in the
correct position (they should be in the low re position).
2. Burner Drawer Checkout
The access cover on the head extension should be
removed to inspect the burner drawer assembly and
mounting to insure that all components are secure and
in their proper position. Figure E-1 shows the location of
the components in the burner drawer. Some components
can be adjusted to improve combustion and can
operate through a range of dimensions. Other
components, like the pilot, must be in their identied
position to work properly.
