FUEL FEED SYSTEM (LIGHT OIL)
The burner pump should receive fuel from a feed circuit which has an ancillary pump and, in some cases, a
pressure regulator capable of modifying the pressure value 0,2 to 1 bar (see drawing 0002901120).
In this case, the value of the fuel feed pressure at the burner pump (0,2 ÷ 1 bar) should not vary when the burner
is at a standstill or when it is operating at the maximum fuel delivery required by the boiler. Normally it is possible
to realize a circuit without a pressure regulator as shown in drawing n° BT 8666/3.
The feed circuit must be realized according to drawing 0002901120 or to drawing BT 8666/3.
The dimension of the pipelines should be in function with their length and with the output of the pump utilized.
Our instructions cover the basic requirements needed to ensure effi cient operations.
All rules and regulations existing in the country of installation should be strictly complied with and the local fi re
brigade should be consulted.
FURTHER INSTRUCTIONS TO START A MIXED BURNER
It is advisable to fi rst carry out the starting with the liquid fuel because in this case the delivery is conditioned by the
available nozzle whereas the delivery of methane be varied as you like by working on its delivery regulator.

AT TWO FLAMES OR MODULATING ONES OPERATING AT LIGHT OIL OR
HEAVY OIL WITH MAX. NOMINAL VISCOSITY OF 5 °E AT 50 °C
1 - Main tank
2 - Filter
3 - Circulation pump
4 - Water outlet and circuit
5 - Air/gas outlet usulally closed
6 - Degasifi erand combustion recovery tank
7 - No return valve

The light oil recovery tanks
(diameter 150 mm height 400 mm) should be
installed as near as possible to the burner and
should be about 0,5 m. higher with respect to
the burner’s pump.
