GENERAL ADJUSTMENTS
DO NOT service this unit
while it is running. The high-
speed mechanical parts as well as high
temperature components may result in severe
injury, severed limbs, or fatality.
ENGINE SPEED
1. To adjust the engine RPM, refer to the Briggs &
Stratton Engine Operation and Service Manual
for specific instructions.
DO NOT attempt to adjust
without a tachometer and
NEVER adjust the engine above 2600 RPM.
FUEL BURNER PRESSURE
The fuel burner pump pressure adjustment screw is
located on the right side of the pump while looking at
its name plate. While the unit is running at full RPM,
insert a screwdriver and adjust until the fuel
pressure gauge reaches 100 PSI.
BURNER COMBUSTION AIR
The combustion air comes from a squirrel cage
impeller. The air inlet is fitted with an adjustment. Air
adjustment can best be measured with a smoke
tester (Bacharach Model RCC_B or equal.) Factory
setting is for a number 2 smoke spot or better. If you
do not possess a smoke tester, then observe the
burner exhaust gases. Black smoke indicates not
enough air, white smoke indicates too much air. To
adjust, loosen the locking nuts, and turn the
adjusting screws until the combustion gases are
clean.
BURNER ELECTRODES
Proper positioning of the electrodes is critical to
assure normal ignition and clean burning. The
design of the burner is such that the electrodes are
locked in the proper position when they are installed
in the electrode bracket. Adjustment is not required.
