Fuel Pump Pressure Adjustment (Fig 4.)
The Fuel pump pressure is factory set and must be checked and adjusted by
qualified technicians only. Tampering with the unit may be dangerous.
Remove pressure gauge cap (P). Connect a pressure gauge on the pressure
measuring port on pump. Start heater and read fuel pressure value. If necessary
adjust pressure to the correct value turning the adjusting screw (P1) clockwise to
increase, anticlockwise to decrease the pressure:
HIGH ALTITUDE ISTALLATION
Due to lower oxygen rate with reference to high altitude installation on sea level, it
may be necessary to increase air rate by opening the air collar (Fig. 8), or to reduce
the setting pressure on fuel pump (Fig. 7). This setting adjustment can be necessary to
prevent excessive smoke emission due to lack of Oxygen.
