5.3.4. Flame
Sensor
To install the flame sensor, 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
screwdriver) and remove the cover.
4.
Disconnect the flame sensor wires and unscrew (counter-clockwise)
the flame sensor from the fuel block.
5.
Screw (clockwise) a new flame sensor into the fuel block.
6.
Connect the flame sensor wires to the main harness ensuring both
sides of the connectors have matching YELLOW heat- shrink.
7.
Screw the front cover in place.
8.
Connect the main 12VDC power to the heater.
