Back with some good news.
I'm pleased to say after a lot of stress and asking a lot of questions, our stove is now working as it should.
The flexible liner was installed and insulated. A stainless steel plate was also fitted at the top of the alcove/opening. The offending adaptor was also removed.
After some discussion with the builder and installer, they agreed that I should have been offered this level of install from the start. But as it wasn't required by law here, that they hadn't done anything wrong by just using an adaptor. On the guidance of a solicitor, I regretfully accepted that this was the case and we came to an agreement on the cost of fixing the issue properly.
I had to pay for the materials at £400 ($650) and the labour (2 men for 1 day) was covered by the installer. This was considerably cheaper than any independent quote to fix the problem, with the cheapest coming in at double that.
I've been burning wood for over 2 weeks now with everything working as it should.
I just wanted to stop by to thank you all again for the free advice and support. You really have a great forum here and I owe you all a beer.
Ryan.
