Oil pump
We recommend that you use a heating oil filter with return inlet when changing over to a single-pipe system.
This leaves the pump operating in twin-pipe mode. Install the feed
and return burner hoses to the filter. Open the oil tap on the filter.
Start up the system.
11. Oil pump
The pump pressure must be set to match the relevant capacity.
The specified pump pressures are standard values and may vary according to system conditions.
For this:
Remove the 4 sealing plug.
Screw in the pressure gauge and adjust the pump pressure with the regulating screw.
