HYDRAULIC CONNECTIONS
The pipes that connect the tank tothe burner should be in perfect tight condition; we recommend the use of copper or steel pipes of an
adeguate diameter.Fuel gate valves should be fitted at the end of the rigid pipelines.Fit the filter to the suction pipeline after the gate
valve. Connect the flexible fitting to this, which in turn should be connected to the suction of the burner pump. Connect the flexible fitting
to the return pipe after the gate valve, and then connect it ot the pump return. Filter, flexible pipes and relative connecion nipples are
standard burner accessories. The pump is provided with special connection points for the insertion of control instruments (manometer
and vacuumeter).To ensure reliable and silent operating conditions, the vacuum in suction should not exceed 35 cm Hg equal to 0,46
bar.Maximun suction and return pressure 1,5 bar.
