Picture Information. The first industrial chimneys were built in the mid-17th century when it was first understood how they could improve the combustion of a furnace by increasing the draft of air into the combustion zone. That causes the bottom of the vertical column of hot flue gas to have a lower pressure than the pressure at the bottom of a corresponding column of outside air. 10.3 fl. That higher pressure outside the chimney is the driving force that moves the required combustion air into the combustion zone and also moves the flue gas up and out of the chimney. 56 posts.

The wall around the flue needs to be sealed, both internally and externally. However it does look like they could perhaps have cut the male end of the flue pipe to length so that the swage - the rounded bit that sticks out near the end - came to rest on the top of the stove flue spigot - ie so that there was no gap left between it and the stove flue spigot.
