high temp silicon

[droid_ca]

does this stuff get warm as I'd like to have a small chimney (3inch) but I'm worried about causing a fire so I thought if I made a bigger hole and filled it with a couple of tubes of this and some other fire proof stuff it would be like a fake chimney with the real one safely inside and it might add to the nostalgia of my cabin thinking of using some fake brick wall board cut it out to make a square box and cover that with the silicon ...would it work or would it be a fire hazard

Thanks...

FIREHAZARD for sure.
To have the best luck with fire resisantant chimminey, would be to find some double or triple wall stovepipe.
I have seen it as small as 4" don't know about any thing smaller tho.

I"m having trouble visualizing what you want to do. Run a 3" stove pipe through the roof of your teardrop?

If so see:

You could also make something like this.

is there any way that I could dress it up with a fake chimney around the real one is there a certain distance I'd have to have away from the pip cause if it's that hot how do I stop it from burning up when it goes through my roof....

Thanks..

Double wall the pipe as it goes through your chimney. Wrap the pipe in fiberglass to insulate the pipe from the chimney" (which I think you're planning to make out of wood). You could buy two of the feed throughs one at your roof and the other at the top of your chimney. You could make the "chimney out of metal and paint it and insulate it with fiberglass, or you could make your own double wall feed throughs. A good old time hardware store might have bigger feed throughs that you could look at and see how they are constructed.

Hope this helps.

Cheers,

Ya that does Gus thanks a lot my actual chimney is 3 inch pipe so I can go up to a 5 inch pipe and it should be good and then there will be no leaks cause we know how trailers are that leak....

We have a wood stove/heater in our lounge room that heats the entire house. It has a flue tube from the top of the heater that extends about 5 feet above the roof. There is a second flue tube from the roof down to the ceiling and then 6 inches lower. There is a 1" gap between these two flues. A third flue extends from the lower end of the second tube and terminates at the roof line in a collar that seals all three tubes. There is again, a 1" gap between the two outer tubes. There is some form of insulation between the main flue and the second one. The sizes of these tubes are,
The main flue, 6" dia, stainless steel, about 18 gauge.
The second flue, 8" dia, stainless steel, about 18 gauge.
The third flue, 10 inches dia. stainless steel about 18 gauge.
There is NO SILICON used whatsoever. Silicon is very dangerous if it should become overheated, it will reduce to release highly toxic fumes that will kill you very quickly. When the fire is stoked up on a cold night and or day, (5 deg, C in the tropics), the main inner flue almost glows from the top of the heater to about 2 1/2 feet above the top of the stove.
Five deg. C I hear you say? Stop laughing! this is freezing cold for us down here.
We are very fortunate in living where we are. The temp in summer rarely goes above 38 C. Living within the coastal area of the Coral Sea, we are cooled by the prevailing South East winds that sweep across the Pacific Ocean. The nearest city to us is 38 Klms west and averages 8 or 9 degs. C hotter, last week, we were 10 degs cooler, wonderful.
