That's not a bad idea, mind you that's if you havnt got a steal partition, also that would be quite a long flue with a significant bend !!!
New shape Dispatch so no steel partition and about 5ft of flue or less depending where I position the boiler.
That length of flue might cause the boiler to cut out but its worth a try.
Unfortunately with the dispatch if you leave the back doors open you can open the side door then reach
in and open the front which means my insurance would be invalid.
So leaving the back doors open isn't an option for me.
