FUEL-FED SYSTEMS (FUEL OIL)
The burner pump must receive fuel from a suitable feed circuit with an auxiliary pump equipped with a pressure
regulator adjustable between 0.2 and 1 bar. The fuel must be pre-heated to a temperature of 50 - 60°C.
In this case the pressure of fuel feed to the burner pump (0.2 - 1 bar) must not vary whether the burner is stopped
or working at maximum fuel delivery required by the boiler.
The feed circuit must be executed according to our drawing no. 0002901120.
The piping must be sized to suit the length of piping and the delivery of the pump used.
Our instructions only concern that required to ensure good operation.
SPECIFIC INSTRUCTIONS FOR IGNITING A MIXED FUEL BURNER
It is advisable to first ignite the burner using liquid fuel, as this feed depends on the nozzle available, whereas the
methane delivery can be regulated at will, by operating the relative flow regulator.
