FUEL SUPPLY SYSTEM
The burner pump must receive fuel from a suitable supply circuit, including an auxiliary pump with pressure
adjustable from 0,5 to 2 bar. Fuel must be pre-heated to 50÷ 60° C.
The supply pressure value of the fuel at the burner pump (0,5 ÷ 5 bar) must not vary either when the burner is not
in operation or when it is operating at the maximum level fuel supply called for by the boiler.
The supply circuit must be built according to our drawings n° BT 8511/5 or BT 8513/6 even when low viscosity fuel
is being used. Pipe dimensions depend on their length and the capacity of the pump being used.
Our instructions only regard what is necessary for ensuring good operation.
The regulations to be observed in order to comply with antismog laws as well as the local Firemen's' regulations,
should be referred to in the relevant publications.
