Fuel System
The fuel is drawn from the vessels fuel tank through a fuel standpipe. This stand pipe can be utilized on vessels with a spare
threaded port, or if no threaded port is available, a 1" hole can be drilled into the tank and the universal tank boss installed.
Keep the fuel standpipe 2" from the bottom of the fuel tank.
Fuel Supply
The fuel can be used from the vessels fuel tank or from a separate fuel tank.
Note: A sign must be affixed to the fuel filler neck warning that the heater must be switched off before refuelling.
Fuel line parameters
A = Suction height 6’ 6" (2,0 m)
A+B = Suction length 33’ (10 m)
6. Cut or extend fuel stand pipe to length, approx. 2" off fuel tank bottom
• mount stand pipe in fuel tank
7. Install the universal fuel stand pipe
• use 1/4" or 1/2" spare port on fuel tank (if available) and install fuel standpipe
or
• drill 1" hole on top of tank (assemble tank-boss and fuel standpipe) and install assembled universal fuel
standpipe
8. Route and secure fuel line from heater to fuel tank.
9. Connect fuel line to fuel stand pipe suction and return using rubber fuel hose(1/4" [6 mm]) meeting SAE 30RI specifications.
