Have any of you guys ever changed the main heat exchanger on one of these god awful boilers???
Had a right ******* doing it! The sump gasket is a tiny bit too small so need to stretch it over, but everytime you get over all 4 corners and let go, at least one corner would pop off! You need to place the heat exchanger on top of the gasket quickly before it pops off!
A little tip if you are unlucky enough to do one, get some small crocodile clips and clip the seal down on the corners, but be careful they don't tear the rubber gasket.
