I need to change the orientation of my glowworm swiftflow80e flue from horizontal to vertical because of an extention I am building. Due to the age of the boiler I can't get an original flue. Firstly, can I use a vertical flue and secondly can I use any flue that is of the same diameter to terminate through the roof of the house?

u cant put just any flue on any boiler regardless of dimensions.a boiler is tested over a period of time under test condition .u cant just fit any old flue because theyre the same size

you can alter the flue not a problem, the problem is that its illegal to touch the flue if your not corgi.
