316 or 904 flue liner

jon1981 · 2016-02-21 20:02:23

Hi, Just curious about peoples thoughts on this. I've had 3 or 4 quotes now from stove installers and they are all quoting 316 flue liners despite the fact that we are installing a multi fuel stove and from my reading online we should be using the more expensive 904 grade flue as 316 is only for wood burning due to it…

Hi,

Just curious about peoples thoughts on this. I've had 3 or 4 quotes now from stove installers and they are all quoting 316 flue liners despite the fact that we are installing a multi fuel stove and from my reading online we should be using the more expensive 904 grade flue as 316 is only for wood burning due to it burning at a lesser temperature than coal. Can anyone clarify if we need 904 grade?

thanks
Jon

open to correction but 316 I think comes in two grades. One of them is suitable for coal stoves. 904 is a higher grade and usually has a longer warranty with a higher material cost.

I have twin wall 316 liner and have been burning coal as well as painted skirting boards etc. No issue yet 3 years in.
