1. Refer to the wiring diagram in figure 7, locate the power and ground
connections on your heater. The ground terminal is located one inch to the left of the fuel
inlet. Connect this terminal to a good, clean chassis ground, using the wire size listed in
Table 1.
2. Refer to the wiring diagram and connect the red power lead from the heater
fuse to the vehicle electrical system, using the wire size specified in Table 1. This line
should be hot at all times, so the heater can purge even if the vehicle ignition is off.
Protect the vehicle with a circuit breaker or 10 amp fuse in the feed line.

Ground the heater electrically through the ground screw provided
on the heater case, and connect to a clean, secure chassis ground. Do not use
the fuel line as a ground or electrical conductor. Use of the fuel line as an
electrical or ground conductor can result in fire or explosion. Do not rely on
heater mounting studs to provide electrical ground.
