5.3.1. Fuel Solenoid
To install the fuel solenoid, do the following:
1.
Turn off service switch and allow the heater to completely power
down (this will take 2 minutes).
2. 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.
3. Remove the screws from the front cover (using a Philips head screw
driver) and remove the cover.
4. Disconnect the wires to the fuel solenoid.
5.
Unscrew the fuel solenoid coil housing from the solenoid body
(counter-clockwise).
6. Make sure the old O-ring and plunger are removed as well.
7. Unscrew the coil housing from the new solenoid including the new O-
ring.
8. Carefully screw back the new solenoid coil housing into the body
without damaging the O-ring.
9. Connect the fuel solenoid wires to the main harness ensuring the
connectors and the fuel solenoid wires have matching BLUE heat-
shrink on both sides of the connectors.
10.Screw the front cover back in place.
11.Connect the main 12VDC power to the heater.
