Dan yeah 5 years running a company but was this company not given to you already being succsesful, these cupboards you dismantle BG engineers tell customers to strip it out .AND rightly so . SO it will not affect a service time,Also i hope they have purpose provided ventilation and not just a cut out in bottom an top of cupboard.. 552 was used as an example because back boilers take longer to strip down than most normal boilers.. some of latest condensing can be a pain admitted
ChrisR have not got a clue available from BAXI but if it is BG should be able to get it, but as sheet would still be there i would imagine most BG engineers would glue it back in place. Came across many back boilers with pipes across front but by taking heat shield off and sliding front up and out boiler could still be serviced, and most of them where not BG installs
As for BG horror stories yeah i could tell you loads some really stupid some just genuine mistakes, but i could also tell you far worse carried out by CORGI REGISTERED engineers.. Back to back fire in same flue, normal fire fitted as balanced flue, balanced fire flue fitted as a normal fire in chimney, boiler fitted on its side because this is only way it would fit in cupboard, pipes joined with areldite, cooker fitted on garden hose and jubilee clips(its rubber and so is cooker hose~).. Pipes joined with soap as a sealant/ insulation tape also, and some a lot more scary than this
Yes bg drop ****** but they do over 5 million jobs a year and at present they have a relatively
in experineced work force, but the training they get and information available to them is far superior to anything any of yo will get. It all depends wether they absorb it and put it to use.
Drunken rant over
