Sealing around boiler flue

[richardadc]

I have a Glow Worm 24ci boiler with a vertical flue going through the loft and out the roof. As I'm having some condensation issues in my loft I'm looking at sealing all the gaps in the ceiling leading to the loft. My question is what can i use to seal around the boiler flue? Would ordinary foam filler be ok?

Thanks

i use red devil onetime, or use a closesure plate and silicone.

So i'm guessing that as you've used a standard filler it should be ok to use the foam filler too? I'll be using that for the other holes so it would make things easier. Feeling the flue i'm not sure it ever gets that hot anyway.

If an RGI can confirm i'd appreciate it.
