View the thread, titled "Cant adjust Danfoss pressure am I using correct ports?" which is posted in Oil and Solid Fuel Forum on UK Plumbers Forums.

I have a SIP space heater and fitted a new matching spec oil nozzle as part of a service on it.

I wanted to check the pump pressure with the new nozzle and its difficult to be sure what port to connect to.

And that these pumps are definitely adjustable! I turned an Allen screw which is not tight so I presume it's the pressure adjuster and after 1 full turn the gauge stayed at 22psi. Spec says 28psi.

Do I keep adjusting or what do you guys think?

Above top screw is the only one which appears adjustable.
