I am having a new boiler fitted I live in a semi detached house which the balanced flues mime and the neigbours are only 13"apart it has been like this since the houses were built in 1992. I am having this done under a goverment scheme. I have been told this has to be done under new gas safe regs. Does anybody know if this correct. They will fit this flue kit to move the flue exit over to exhaust gases over my kitchen window. Many Thanks Trev
