GAS PIPE NETWORK AT AVERAGE PRESSURE
N° BT 8531/1
HYDRAULIC CONNECTIONS (LIGHT OIL)
Pipe connections from tank to burner must be perfectly tight.
It is recommended to use copper or steel pipes of adequate diameter (see table and drawing). Fuel stop gates must be
installed at the end of the rigid pipes.
The burner is supplied complete with filter, hoses and connecting nipples.
The pump is provided with ports (see figure) for fitting control instruments (pressure and vacuum gauges). For safe, silent
operation, negative pressure must not exceed 4 m.W.C. equal to 30 cm.Hg. If necessary, maximum pressure for
suction and return should be 1,5 bar.
