Removal of buderus 500 combi heat exchanger connection plate

[Leezygeezer]

Hi everyone,
i have a boiler with a leak from cold water inlet and DHW outlet connections into the plastic heat exchanger connection plate.

it is almost impossible to see if the leaks are from the brass nipples or a crack in the plastic block so I am going to replace both just to be on the safe side. So my question is do the brass nipples screw out from the bottom, or does the block need removing from above?

i had an exploratory attempt to remove it from the top, but it seems like virtually everything has to be removed to get the plastic block off.

if anyone has any tips they would be gratefully received

regards

lee
