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.
