Chimney experts: advice sought please- gas flue for wood burning
stove?

I might have missed something along the way as I don't understand
whether the existing chimney actually has some form of "stainless steel"
letterbox flue liner or whether the flue is concrete block in
construction (gas tight). If the latter then go with the following.
(or at least give them a call to describe your current chimney construction)

"DO I NEED TO LINE MY CHIMNEY TO THE TOP?

If your chimney is in good order with no leaks i.e. no leaks of smoke
into your upstairs rooms, your attic or your neighbours` house, in the
case of a semi, then the answer is NO you do not need to line your
chimney nor is there anything in Building Regulations which states that
you must line. The rule here is NO LEAK NO LINER.

MY CHIMNEY DOES NOT LEAK BUT I HAVE BEEN TO A SHOP AND THEY TELL ME I
MUST LINE IT. IS THIS CORRECT?

In a shop or on other websites you are dealing with sales people. Here,
at Wood burning Stoves Limited.com , you are dealing with HETAS
qualified solid fuel engineers. The sales people in these shops are
attempting to pressure you by mis-selling a chimney lining kit. Selling
you something you do not require in order to obtain a higher commission
percentage on the sale. Building Regulations Part J. (Sections 1.36 –
1.39 a chimney only requires relining if the chimney is defective).

WHEN MUST I LINE MY CHIMNEY?

You must line your chimney, chimney top to stove, if it is defective
i.e. leaks smoke into your house, attic or your neighbours` house. We
can supply full lining kits for this purpose."

Hope that helps.
Just because somone claims to have a "qualification" it doesn't mean
they are the be-all and end-all authority on a subject.
(You only need to watch the rogue exposure type TV programs to realise
that!)

Cheers
