12.
Place a feeler gauge between the combustion air
blower and the flat surface of the blower casing.
Slowly tighten (or loosen) the retaining nut, holding
the combustion air blower, until a .003-.005 gap is
achieved. Remove feeler gauge.
13. Spin the combustion air blower to ensure a friction
free rotation.
14. Reattach the blower housing to the blower casing
using the four blower housing screws. Reinstall the
clutch half on both the motor’s shaft and the com-
bustion air blower’s shaft. Attach the motor and
flange assembly, with the recessed edge of the mo-
tor flange in-line with the wiring access slot of the
blower casing, to the blower housing with the three
hex head screws. Reconnect the black (+) and
brown (-) wires of the motor to the C-plug harness’
black (+) and brown (-) wires. Feed the C-plug
harness’ yellow and brown wires back through the
wiring access hole in the protection cap.
15.
Reinstall the protection cap. Reconnect the black
(+) and brown (-) wires of the ignition coil to the C-
plug harness’ yellow (+) and brown (-) wires. Rein-
stall the ignition coil and secure to the protection
cap with the four ignition coil screws. Reconnect
the ignition cables to the ignition electrodes.
16.
Fit the nozzle stand plate inside the cast aluminum
blower casing and secure in place with the four noz-
zle stand plate screws. Reattach the fuel supply and
return lines to the diesel-burner head.
17. Reconnect the blue (+) and brown (-) wires to the
fuel solenoid’s (+) and (-) electrical terminals. Al-
so, reconnect the flame sensor’s green wire to the
green C-plug harness wire and the blue wire to the
C-plug harness’ violet wire.
18. Follow the instructions for reattaching the diesel
burner, in the detaching/reattaching section in this
manual.
NOTE:
If the combustion air blower is rubbing, loosen the
retaining nut slightly and lightly tap on the combus-
tion air blower’s shaft (opposite side) then readjust
the gap.
NOTE:
Inspect the clutch halves’ for cracks and also ensure
that the flat portion in each shaft hole is free of
wear and tear. Too much play on the shaft produc-
es a loud clacking noise. If any cracks or wear are
detected, the clutch half must be replaced.
