Tony, I'm going to take a late night, feeling tired and unwell chance to be pedantic! You correctly say the 600mm Reg refers to an opposing wall (actually says opposing surface) but the boundaries are treated as such as one could be put there. Same applies to along the boundary, ie 300mm from internal/external corner -should it be put there.
Worcester show a boundry on their diagram with the reference to 'opposing surface'. Vaillant quotes BS 5440-1 re the '2m from opening in building opposite' and 'are not directed to discharge across a boundary'. How far would that be I wonder? 2.5m (not mentioned) would cover it perhaps or do we need a 'range' for each boiler?
Seems to me that ODPM guidelines have caused much confusion and the sooner they give us some updated Regs the better.
The MI's by the way are for a 40CDi and Ecotec 831 which I think are their latest releases?
