lame plumber
just hung an ecotec 837 today, bleedin heavy thing, over complicated heap looking inside. Customer supplied, taking forever as I only fit the good old intergas and dont know this one. Of note, check it hasnt been dropped by the merchant Ray, the one today had to have my size 9 straighten out the bottom support 🙂 wouldnt fit any of the ones on your list myself, I would have sweet talked you into an unvented and system boiler, theres always room somewhere 🙂
