Where the oil tank installation is at a higher elevation
than the burner, please note:
Some local Codes of Practise may stipulate a shut off
valve to stop the gravity flow of oil into the supply line
during burner shut down.
-weishaupt- recommend the use of a solenoid valve ➁ in
the supply line. The solenoid valve must be slow closing
so as to relieve any oil pressure back to the oil tank.
Control of the solenoid valve see Ch. 5.5
Ring main operation
When operating several burners, or with larger distances, -
weishaupt- recommends the oil is supplied via a pumped
ring main. For installation and operational drawings see
technical worksheets.
Oil supply pump
If the permissible suction vacuum is exceeded, an oil
supply pump must be used. Note:
• Maximum supply pressure of 2 bar to the oil pump on
the burner.
• Operation of the oil supply pump is generally in
conjunction with the heat demand of the burner.
Pipeline lengths dependent on:
• Elevation difference (H) between pump and tank
• Oil throughput / pump type
• Pipe line diameter (DN)
The pressure losses of additional fittings are not included
in the following selection table showing pipeline diameters.
➀ Oil pump on burner
➁ Solenoid valve (slow closing)
or shut off valve to stop siphonic flow
➂ Oil tank
