Q2: When the fuel pump is running, does fuel come out of the bleed
valve?
IF
YES:
Place your finger on the air compressor’s air filter. Once the
air compressor turns on, there should be enough suction to
keep your finger in place. Proceed to Q3.
IF NO:
1.
Check the internal fuel filter to see it is clogged. If it is,
replace the filter.
2.
Once the fuel filter has been replaced, restart the heater.
During the first 7 seconds when the fuel pump is
running, ensure the fuel bleed tap is open and check
that fuel is flowing. Proceed to Q4.
Q3: Once the air compressor turns on, is there enough suction at the
inlet of the air filter to hold your finger in place?
IF NO:
Change the air compressor.
IF YES:
Check the glow of the igniter. Turn off the service switch
and allow the heater to completely power down (this will
take 2 minutes). To check the glow of the igniter, do the
following:
1.
IMPORTANT: Disconnect the air compressor wires from
the main harness. Disconnecting the wires ensures that
the heater will not attempt to fire if the heater is
accidently turned ON. This will make it safe to view the
igniter with an open burner box.
2.
Remove the screws on the front cover and remove the
cover.
3.
Loosen the thumb screw on top of the fuel block and pull
the fuel block out from its mounting position.
4.
Ensure that the igniter tip is in a horizontal plane.
5.
With the fuel block out of the way, turn on the heater
and observe the igniter during the first 10 seconds.
Note: the heater will stop and show a flame out.
Proceed to Q6.
Q4: Once the fuel filter has been changed and the fuel pump is running,
is there fuel coming from the opened return bleed valve?
IF YES:
Problem solved.
IF NO:
1.
Change the fuel pump.
