i want to buy a s/h solid fuel rayburn and fit it in my kitchen. currently there is no chimney, i have seen chimneys for these on the outside of properties but cant find any information on how exactly to do this. the kitchen is single storey but has a pitched roof shared with my neighbour so it would be better on the outside . i dont know if i have to inform building regs etc either, i would be extremely grateful for any advice.
