NB: CARE MUST BE EXERCISED WHEN USING A TOP EXIT OIL TANK AS A NON-RETURN VALVE
(FOOT VALVE) MAY ALREADY BE FITTED.
The use of two non-return valves will cause damage to the fuel pump and will invalidate the warranty.
4:8.5 Deaerator Oil Pipe System
An alternative two pipe arrangement can be achieved using a 3K-Oil Loop Deaerator which removes the air
from the oil feed on a single pipe lift. The Burner Pump is piped to the Deaerator, which should be positioned
close to the burner.
A Non-Return Valve is not required in the return line.
The advantage of this system is gained where a two pipe run from the oil supply tank is long or difficult to
achieve.
