Fuel System
The PH41A fuel pump and fuel system are the heart of the heater. The fuel pump not only delivers fuel
to the heater but also controls the amount of fuel delivered. The pump is designed to operate like an
electric solenoid and works using electric pulses. Each time it is energized, it provides a measured dose of
fuel. It is critical to the heater’s operation to stay within parameters outlined in Figure F1 and only use the
components provided.
System Layout & Considerations
•
Keep the length of the fuel system short as possible.
•
Mount the fuel pump as close to the fuel pickup as possible (pump pushes better than it sucks).
•
Minimize vertical rise.
•
Mount the fuel pump in a protected location away from road spray.
•
Choose a mounting location for the fuel pickup pipe that is close to the heater and offer installation
access.
•
Design your fuel system so that Figure F1 fuel line limits are not exceeded.
