10741 Stufa flue gasket problems

HI, My father was recently at his home in Italy and was sold a stufa which came with the flue piping and some silicone/rubber gaskets which are meant to fit in between the flue pipe joints. However he has tried like ******y to get the flue gaskets to fit in between the piping but he can't get them to seal/seat correctly. Anyone got any ideas how to install the flue with the gaskets or if they have had similar problems.

Many thanks.

You might try to use some washing-up liquid to ease the gaskets (if they are like rubber O rings) onto the pipe. If you have another type then it is just down to trial and error - mostly error to start with... Good luck.

I'm surprised to hear this - I have bought a lot of flue pipes for stoves, and liners for chimneys, but I've never seen a gasket!

Since your father got the pipes with the stove it seems unlikely that they are pipes designed for some other use (my first thought) but I would be a bit wary of them. Most commonly stove pipe flues are just pushed together, without sealant, (or you can use a high temperature silicone sealant out of a tube).

If the stove is Italian the chances of you being able to build the flue the right way up (spigots on top, sockets below) without scouring the whole country for the right adaptor is very small.

Hi
You can also get red paste which works like a gasket, whos name I cant remember sorry, but if you ask they should know what you mean,

Has anyone actually seen these gaskets before?? I can't see why he has been sold them if they aren't supposed to be used?? We have a stove in the UK and its simply a matter of pushing the flue pipe together with a sealant. I wonder if he could ditch the gaskets and just use paste??

We had the rubber type, and like you say, a total pain to fit, hence we went for the paste

Did you just throw the rubber seal away completely and replace it with a sausage of paste??

I think one of them got wedged down a pipe, and I throw the others out......words of warning the paste is really messy to use.

If you've got rid of or can't fit the rubber things, you'll probably get a better seal by pushing in a circle of the fireproof string/rope made for gaskets before you add the sealant. This rope is available in a wide variety of thicknesses, though Italian suppliers local to me only tend to sell a couple each. I suspect local installers add layers or shave the thicker ones.

I've also found that high temperature stove mastics (widely available) are a lot easier to put in effectively (with a mastic gun) than it is to trowel in a paste. Though the mastic still needs replacing every few years which is a pain.
