Problem with heating (chimney liner)

[run_PAFC]

Hi everyone,

I'm posting this on behalf of my uncle really. He has been renovating a bungalow for the past 10 years (long project!) and is on the home straight now (i.e. fitting kitchen and other stuff).

He has come acros a problem, however, with the chimney. He recently bought a new woodburner for the lounge without assessing the state of the chimney. When he returned and investigated, the chimney liner which is currently installed is approximately 5 feet short from the bottom of the chimney. Therefore, when the woodburner is in position there is a 5 feet gap between the woodburner outlet and the start of the chimney liner. The problem is how the best way to go about inserting a short piece of liner from the woodburner to the existing liner.

Apparently flexi-liner is a possibility but how that would fix to the existing liner I have no idea - due to the fact you can't reach it from underneath. Is there some way of shoving flexi-liner down the top of the chimney and fixing it in place at the top?

Or is there a better way of overcoming this problem?

Any suggestions or tips would be most grateful.

Thanks

James

The liner should be one piece from the fixing at the pot to the fixing on the register plate. You really should remove the old one and put a new one in.

and for a woodburner you need a pretty solid liner, not that flexible bacofoil stuff you can use with a gas fire.

The supplier of the stove should be familiar with the need, and may supply something suitable.

Thanks both for your replies - very helpful.

Have you notified your local Building Control Officer before working on the chimney liner.

"Flues are controlled services as defined in Regulation 2 of the Building Regulations, that is to say they are services in relation to which Part J of Schedule 1 imposes requirements. If renovation, refurbishment or repair amounts to or involves the provision of a new or replacement flue liner, it is "building work" within the meaning of Regulation 3 of the Building Regulations. "Building work" and must not be undertaken without prior notification to the local authority.
