I have chosen a stove. mistakenly thinking it was a 125mm outlet. Not bought yet but I WANT THAT ONE.
Now a previous fitter suggested not to bother lining the chimney - nothing to do with flue size particularly, he just thought that it was unnecessary. I've had a couple more out to do surveys and they seem to think that the liner would be a much better option. Reading around, I tend to agree.
What are my options? The chimney is 7" square at the base but there are constrictions further up that would require a flexible flue liner to get around. 5" liner seems feasible but not 6". Is there any advantage to putting a 6" liner up "as far as possible" and leaving the remainder unlined, are there any ultra flexible liners that might be suitable?
I know that I can't use a 5" liner with an adaptor for legal reasons. What is the worst that could happen if I leave it unlined? Pics below.
