5" Flexi Liner Stuck

davemie

Hi guys, I'm putting in an Stanley Oisin stove and a 5" double walled flexi liner.

I had two guys around today trying to install the liner but with no luck. They started off by putting a rope down the chimney, attaching the rope to the liner, making the top of the liner into a cone shape and pushing/pulling the liner down the chimney from the top. However, the liner would not go around a bend in the chimney about two meters from the top.

Next they tried to pull/push the liner up the chimney from the bottom. This time again, it got stuck at the same bend about two meters from the top.

They now suggest that they cut the liner to that length and push it up as far as they can. This means that the bottom seven meters of the chimney would be linded and the top two meters of the chimney unlined 8" clay pot.

Is this a good idea? Would this cause problems with drafts etc? Have I any other options do I have?

The chimney is about 30 years old and hasn't been used for at least the last 7 years.

Tnx for you help

Could they cut it as suggested. Cut another piece and drop it from above?

It should go the full length of the flue, even if it means knocking a hole in the wall to get thru to the top.If thats the best they can do I'd get someone who is more competent.

As suggested above it is essential that the liner reaches the top and a cap is fitted. The space between the liner and the old clay liner should be insulated with vermiculite or similar.
If cutting open the chimney at the bend is not an option you would like to take it would be preferable to fit an adapter at the base of the clay liner and not re-lining than stopping the liner before the top.
Joints in the liner are not allowed and not necessary
Did this pair of fitters just go home with their tails between their legs?, I hope you didn't pay them as a fitter is paid to re-line a chimney, not to give it a go and see.

Thanks guys, you have confirmed what I was already thinking. Cutting into the wall at the bend appears to be a very big job as its a semi with a shared stack and there is a large water tank located at that very location, which would need to be moved first.

I haven't paid them yet, but said I would for their two 'half day' 3 hr of work.

I will try to finish do the job myself in the new year, unless a can find somebody good in the Cork area.
