Power flushing a back boiler

[tommy1712]

I got a power flush booked in and they have a back boiler, they have no idea of the make or age or even if has ever been serviced.
is there anything I need to no about flushing them? Or just crack on as per normal?
I use a fernox powerflow with magnetic filter and usually f5

Any chance it might have a scale problem ? as you may need something more aggressive to get rid of scale, and note on some old BBU the vent & Cold feed came right back to the boiler.

Cheers, so just crack on as per usual. I keep a fx2 in the van just incase ever needed but I don't like using it
