Hello all
I was hoping some one may be able to help me.
I have a Potterton performa 28i, thanks to some help on the forumns already I've been able to get all of my radiators warm (balancing them).
However, before that, I had a plumber/engenear attend, who looked inside the potterton, and I've noticed some thing.
Near the horizontal centre of the boiler (when you take the front cover off) there is a black twisty thing, that USED to have paper attached to it, however, the paper has now been broken.
Does any one know what it is for? I can not see any writing on it, that would give me a hint (I like to know what things are for).
Doug
