HYDRAULIC CONNECTIONS
The burner tank connection pipes must be perfectly airtight. We
recommend the use of copper or steel pipes of a suitable diame-
ter.
The fuel shut-off valves must be installed at the end of the rigid
pipes.
The filter has to be fitted to the suction piping after the shutter.
Connect the hose with its connection nipple to the intake of the
burner pump, which are all provided with the burner.
The pump is provided with specific connections to fit control instru-
ments (pressure and vacuum gauge).
For a safe and silent operation, the suction vacuum must not
exceed 35 cm/Hg equal to 0.46 bar.
The suction and return pressure must not exceed 1.5 bar.
