Wood burner Flue Increasing Adapter

[PansyPotter]

My wood burner outlet is 5 inches and I understand the stainless twinwall flue needs to be 6 inches to comply with current regulations and that an easily available increasing adapter will accomplish this satsfactorily.

My question is - is it possible to use a 7 inch flue with this stove? If so, are there increasing adapters readily available to do this?

The documentation that came with your wood burner would/should have stated something to the effect that the flue size must not be less than the outlet flue size for that stove.

One would assume from this that there is no problem with the flue being larger.
From my experience (admittedly, in France, none in the UK, eg http://www.bricodepot.fr/st-brieuc/node/475055 ), adaptors are readily available form one size to another and sometimes from one size to a larger one, skipping the intermediate size.

Try these for a reducer:

Minimum size of twin wall liner is 150mm, you can go larger so long as the liner will go down the stack, adapters are available.
These works come under building control, unless using a Hetas registered installer who will issue certificate.

Thanks to the two people who have replied.

It seems from what you say that increasing from 5 inches to 7 inches is OK. The flue I will use is 7 inch Selkirk twinwall outside flue but I haven't yet found an increasing adapter in the UK to convert from the 5 inch wood burner outlet pipe to the Selkirk 7 inch flue pipe. Where would I get one of these?
