HYDRAULIC CONNECTIONS (LIGHT OIL)
The connection pipes between tank and burner must be completely tight.
We suggest to use copper or steel pipes of an adequate diameter (see list and diagram).
At the rigid pipes ands it must be fitted the fuel’s detection gates.
Filters, flex pipes and relative connection couplings are supplied along with burner.
Pump is equipped with suitable connecting points (see drawing) for detection instruments (pressure gauge and
vacuummeter).
Pressure drop in suction must not exceed 4 m. W.C. = to 30 cm.Hg. for a proper and silent operation.
Probable max. pressure on suction and on the return 1,5 bar.
