Resealing fire stove flue.

[HannsG]

Hi,

New house has had a mixed fuel stove. Been here a year. I burn wood and coal.

Noticed the cement is crumbling away on the flue. And where the flue meets the stove.





Would fire cement or high temp silicone repair this? Which is better?

Thank you

Fire Cement is easy to come by and use. To my untrained eye your register plate looks like its got a crack in it?

Hi, it seems the fire plate was skimmed over and painted by previous owner. It's a crack in the paint.

It is way to hot there for high temp silicone.
New fire cement would crack again like it is now.
I would recommend removing old fire cement and putting in a rope seal instead
as a cheap and easy fix:

You could also get it in black or grey at your local stove dealer.

Please forgive my ignorance. How would you seal with rope? On both parts?

The only rope I have replaced has been that on the inside of the stove door.

Yes, you can't fit rope into a right angle. I have exactly the same problem, caused by contraction /expansion.

This is good to 300C:

Sorry,
I wasn´t able to identify picture 1.
Picture 2 looked like a vertical flue to me.
You could expect temperatures up to 600°C at the flue connector,
depending how and what you fire.
