problem with flue adapter and leaking tar

dingdong1234567

As the title title says I am having problems with my stanley cara stove and tar. Now the stove ws only fitted in the summer and has already had the flue adater from the stove to the 8" clay liner replaced due to leaking tar at the joint between the clay liner and the flue adapter. Well tonight tar is leaking again because of the smell it produces and the fact I can hear it dripping at the back the stove etc.

So what is the solution? Well the guy that fitted the stove replaced the initial flue adapter to see if that was the issue but obviously that didn't work. So am I looking at lining the clay flue? Although I cant see how that would solve the problem here....maybe im wrong?

Any pointers would be much appriciated!

It's not the adaptor that's the problem it's the chimney.If the flue gases cool to quickly it can cause condensation in the flue and lead to tar/cresote

Thanks for that robbie. Yes i did read something similar elsewhere alright. This would appear to be the problem in my case.

I have arranged for the chimney to be lined next week. Because as it stands the stove is unusable due to smell that is being produced.

I hate to tell you this but the tar problem may persist after you have installed the liner if the tar is already well soaked into the chimney blocks. I had a Stanley which had blown the liner and it was a mess. The Stanley was already removed when we bought the place. We tried to seal the stains behind the paint but it still comes through. It also got into the ajoining flue. Worth checking the attic for any signs of tar on the chimney blockwork.

The liner is sound which would suggest minimal intrusion of the tar into the block work. I have checked the attic and the chimney block work is sound. The problem here is that the tar is getting past the stove adapter seal. The quantity of which is minimal but enough the stink the house out. So In the long term I would be happy that it should not be a problem.......hope these words will not bite me in the ass!

Hi dingdong
Clean the chimney well before installing flue. Insulate the flue with vermaculite insulation between the existing flue and the lining flue and make sure it is well sealed at the flue gathering at bottom of chimney and at the top and put on a rain cowl.

NW going to clean the chimney tomorrow alright.

The liner to be fitted is a twin wall liner. Does this need vermaculite? Have a rain cowl fitted already but this may not be compatible with the liner etc so time will tell.

crock!

Most condensation in chimneys is caused by slumbering the stove for excessive lengths of time. Make sure your stove burns at a high heat for periods throughout the day, this helps to burn off condensation .Avoid overnight burning.
