5.
Shim under the burner skid, if necessary, to align the burner horizontal and vertical centerlines with the horizontal
and vertical centerlines of the dryer drum (or combustion chamber). THE ASSEMBLED BURNER MUST BE ON
THE COMBUSTION CHAMBER CENTERLINE AND AT THE SAME PITCH AS THE COMBUSTION CHAMBER.
(Follow the dryer manufacturer’s recommendation for burners used without combustion chambers.)
I. BURNER PILOT SYSTEM
The StarJet Burner incorporates the AIG pilot system (see figures 5 and 6). The pilot and scanners should always be
located to point downward. As delivered, the pilot and main flame scanners should already be properly oriented, based on
the air inlet orientation specified when the burner was ordered. Adjustment and operation of the pilot systems are detailed
below.
1.
Connect the pilot gas supply line to the inlet provided on the burner unit. Size the pilot gas supply line to avoid
excessive pressure drops. For pilot gas supply lines up to 25 feet, use ½” or larger piping.
2.
The spark wire gap is factory set at 1/8”. This gap can be changed by carefully removing the pilot internals. Bend
the spark wire to adjust, reinsert, and check the gap. A nickle can be used as a gauge for adjust-ing the spark
gap.
