Installation of the fuel system.
Do not operate the heater using biofuel.
Use only diesel fuel standard EN590 and petrol fuel standard EN228, depending
on the ambient temperature.
Use the instructions detailed in Fig.18 and Fig.21 to install the fuel system. The fuel
pump and the fuel supply line must be protected from heating.
It is recommended to install a small inline fuel filter before the fuel pump. Make sure
the filter is filled with fuel, and that you are using fuel lines of the same diameter as the
heater.
Do not take fuel from the fuel filter or its casings, as doing so causes fuel leaks.
Do not take fuel from the fuel line between the fuel filter and fuel pump of the
vehicle’s engine, the return line of the engine, or after the high-pressure pump
of the vehicle.
The heater is not designed to work with such high pressure.
The fuel line system should be as short as possible. The recommended
maximum length of the fuel line is 5m. The distance between the fuel tank and
the fuel pump should not exceed 1m, and the distance between the fuel pump
and the heater should not exceed 4m (see Fig.18 and Fig.21).
3.5.1
Fuel suction using a fuel suction hose.
Before installing a fuel suction hose in the fuel tank of the vehicle or vessel,
make sure that the fuel level is high enough to ensure operation of the heater
and low enough to easily remove the fuel tank if needed.
