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 (see table and drawings).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 burner pump return. Filter, flexible pipes and relative connecion nipples are standard burner
accessories. The pump is provided with special connection points (see drawing 0002900480, and 0002900680) 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.
ELECTRIC CONNECTIONS
The electrical lines should be at an adeguate distance from hot parts.It is advisable to make all the connections with
2
flexible elecric wire. Conductor's minimun section 1,5 mm .
