I am having a new fireplace in the ground floor and repairing the old chimney on the roof of a two floor house. The chimney was battered by the weather for almost a century and was a bit tilt at the very top. I decided to remove the last 4 feet of the chimney and replace it with a metal pipe, so as to also reduce the weight. The old chimney had 3 cupped metal flues and a clay one that was open at the top.
Inside the chimney are 4 channels, I believe two form the old fireplace and two from and old bathroom ventilation or an old room. Does it make sense?
The new fireplace has a 5 feet pipe connected to the old chimney breast in the ground floor with no chimney liner. Then, there is a 4 feet metal pipe fitted at the top of the chimney.
I am afraid that the smoke route might not be properly done. Shall I leave it with one pipe flue for all channels, shall I have a second flue for the bathroom ventilation. Or better install 4 flues as before, one per channel?
