2.
Once the fuel pump has been replaced, attempt to
restart the heater. When the fuel pump starts running,
ensure that fuel flows from the open fuel return bleed
valve. Proceed to Q5.
Q5: Once the fuel pump has been replaced, attempt to restart the
heater. When the fuel pump is running, is fuel flowing from the open
return bleed valve.
IF YES:
Problem solved.
IF NO:
Contact Calcutt Boats for further assistance.
Q6: Is the igniter glowing bright yellow?
IF YES:
1.
Clean the fuel nozzle. To clean the fuel nozzle, refer to
5.3.3.
2.
Once the fuel nozzle has been cleaned, attempt to
restart the heater. Proceed to Q7.
IF NO:
Replace the igniter. Refer to 5.3.2.
Q7: Does the heater fire once the fuel nozzle has been cleaned?
IF YES:
Problem solved.
IF NO:
Check the fuel solenoid. Turn off the service switch and
allow the heater to completely power down (this will take 2
minutes). IMPORTANT: Disconnect the main power
(12VDC) from the heater. Disconnecting the 12VDC power
ensures that the heater will not attempt to fire if the service
switch is accidentally turned ON. If the heater were to
attempt to fire with the front cover off, it will project open
flame towards the user. To check the fuel solenoid, do the
following:
1.
Remove the screws on the front cover and remove the
cover.
2.
Disconnect the wires to the fuel solenoid.
3.
Being careful the O-ring stays in place on the brass
head, unscrew the fuel solenoid from the brass head and
remove the plunger (inside of fuel solenoid).
4.
Screw the solenoid body back in place (note this is
temporary to test if the fuel solenoid is a problem).
5.
Screw the front cover back in place.
6.
Connect the main 12VDC power to the heater.
