FUEL (DIESEL) SUPPLY SYSTEM

The burner pump must receive the fuel from a suitable supply circuit
featuring an auxiliary pump which may feature a pressure regulator
adjustable from 0.5 to 3 bar. In this case, the fuel supply pressure to
the burner pump (0.5 ÷ 3 bar) must not change both with burner off
and with working burner at the maximum fuel output required by the
boiler. In normal cases, this circuit can be realized without pressure
regulator, abiding to the following diagram. The supply circuit must
be realized according to diagram 8666/3
The pipe dimensioning must be carried out according to the pipe
length and the flow rate of the installed pump. Our instructions ensure
a good operation of the product.
The anti-pollution prescriptions, as well as the provisions set forth
by the local authorities, refer to the specific publications.

MODULATING BURNERS WITH MAXIMUM NOMINAL VISCOSITY (5°E AT 50°C)
The fuel recovery tanks (diameter ~ 150 mm - height ~ 400 mm)
must be installed as close as possible to the burner at least 0.5
m above the burner pump.
DUAL FUEL BURNER IGNITION INFORMATION:
We recommend performing the first ignition with liquid fuel because,
in this case, the output is conditioned by the nozzle that is used,
whereas the output of natural gas can be varied as required by
regulating the flow rate regulator.
