10. Setting up the fuel system
Warning:
The WhisperGen burner is fuel specific and can operate only on the fuel it has been configured
for. The evaporator at the top of the burner is marked ‘D’ for diesel and ‘K’ for kerosene.
Warning:
For the
diesel burner
use only good quality automotive diesel (BS2869: 1988 burner fuel class
D) with the WhisperGen. Do not use other fuel types such as heating oil, petrol, aviation fuel,
and LPG.
For the
kerosene burner
use only good quality automotive kerosene (BS2869: 1988 burner fuel
class C2).
Warning:
An approved fuel line with an inside diameter of between 2.5mm and 3.5mm shall be used. A
line with a larger inside diameter may cause air/vapour bubbles to form in the fuel line. This
may make it difficult to start the burner and may extinguish the flame during operation. The fuel
line shall be a maximum of 8m in length. Header or day tanks shall be used for longer runs.
Warning:
The distance from the fuel pump and filter to the fuel tank shall be a maximum of 200mm.
Warning:
For marine installations, the fuel system installation where applicable, shall comply with the
Recreational Craft Directive 94/25/EC,
issued by the Council of the European Community.
Warning:
Bleeding the fuel system will cause water pumps and fans to start. Ensure pumps and coolant
circuits are installed and bled before bleeding the fuel system.
If the fuel line is connected to a fuel tank used by other equipment, draw the fuel supply from a
separate outlet.
An ISO Rp
⅛
female fitting is provided on the back of the WhisperGen enclosure for the fuel
inlet.
Mount the supplied fuel pump:
∙
upright at the fuel tank outlet;
∙
level to, or below the bottom of the fuel tank; and
∙
on a soft rubber pad to prevent noise transmission.
An inline filter shall be fitted between the fuel tank and the fuel pump.
To prevent air/vapour bubbles collecting, all changes in height in the fuel line shall be free of
dips or loops.
The vertical range of the fuel level in the tank relative to the base of the WhisperGen is +2m, -
1.25m, see
Figure 9
: Fuel pump and fuel line installation.
It is recommended that a short length of approved flexible fuel line be installed on each side of
the pump to stop the ticking noise being transmitted into the metal fuel line.
