as snapped screw on plate and got very wet and cold i learnt the hard and costly way
The first one that I did took me 2 1/2 hours during which something was not tight and I got a bit wet.
Since then apart from one to help to teach a trainee what NOT to do, I usually recommend that they get a fixed price repair from BG or Worcester.
Ravenheat 620s are not much better when you cannot get a spanner in place for the large connection. Last one but one I had to take back to workshop and heat up as it was jammed solid.

drain off remove heat exch (plate) undo div valve from pump connection. DO NOT REMOVE BYPASS TUBE! simply loosen off left hand flow manifold 4 screws (don't remove fully) Do not touch flow return isolators. Twist and remove div valve. replace all o rings and refit using plenty of molycote grease. Its the bypass tube and left hand manifold that catch a few lads out! a bugger to get back in if you remove it!
