NOTICES
- The oil could easily flow through the pipes if those are properly seized, protected and heated (by electricity, steam
or hot water).
- In order to limit gas or steam production the oil pressure into the gas separator (10) shall be set in function of the
supply temperature, see table above.
- The forwarding pump should have at least a double capacity than that one of the burner. For several burners sup-
plied through the same ring supply line, the forwarding pump should have a capacity of approx. 30% more than the
sum of the single burners outputs.
- For starting-up: after excluding the burner by the shutter valves (5) let the oil flow into the supply ring up to reach
the required circulation; after than open the valves and supply normally the burner.
