I have recently changed a couple of radiators and have read that I may need to top up the system plus replace corrosion inhibitor.
I was all ready to go using the filling loop as read on various forums until I looked at my boiler and it doesn't look the same.
I have a very old combi boiler.....Potterton Puma 80. I have looked at the scanned online manual but can't make sense of it.
Can anyone help....a) how do I top up the system? b) I was planning on adding fernox f1 express via the filing loop, how do I do this?
Many thanks
Jodie
