SECTION 9: DIESEL-BURNER COMPONENTS

Be sure to remove the jumper wire that was used to make the

connection from the C-1 location to the C-7 location. Failure

to do so will result in an overheating condition during normal

operation.

Replacement Procedure:

Remove both the B-plug and the C-plug from the

diesel-burner controller. Gently pry away each side

of the diesel-burner controller bracket from the die-

sel-burner controller’s locking posts with a flat-head

screw driver. Once the locking posts have been

released, pull on the diesel-burner controller to re-

move it from the diesel-burner head.

Slide the new diesel-burner controller into the diesel

-burner controller bracket. Push down on the diesel

-burner controller until the locking posts snap into

the bracket slots.

Reconnect the B-plug and the C-plug.

NOTE:

Be sure to install the diesel-burner controller

with it’s C-plug and B-plug ports facing downward. Failure

to do so, will result in moisture collecting in the ports and

potential damage to the diesel-burner controller’s internal

circuitry.

Coils still will not operate, it is possible the Electronic Con-

troller is defective.
