Due to lack of foresight and knowledge of the regulations we are having an extremely difficult time trying to find a suitable location for a new oil boiler in our extension. Despite it being a substantial construction it seems that the regulations governing flue distance from window, doors walls or access to bends in extended pipework is thwarting us.
With our oil boiler installer we have found one possible location but it is not ideal as it takes up space allocated to other things and is a long way from connection to the existing heating system. One of the issues with locating it in a more convenient position is that the flue exiting ground storey roof would be closer than 750mm from an adjacent first storey wall. Oil boiler man said that the pipework needs to be 750mm from the wall but reading the Approved Document J I'm not sure this is correct because it only refers to the outlet from the flue not the pipework. So my question is could the flue exit the ground floor roof closer than 750mm from the first storey wall and then kick out so that outlet was 750mm from the wall?
