high temp rtv

What do people use for high temp rtv. I realized that my installer didn't use it on the nipple to vent. I want to rectify that. Is 1500f fire blocker a suitable sealant for the exhaust?

usually Rutland brand , comes in caulking tube and small tube sizes , however you can also use high temp automotive rtv if the rutland isn't available near you .

No fireblocking is not suitable for this purpose .

nah just something like this-

Not sure if you're talking about the indoor or outdoor sections of pipe.....outdoor sections don't need to be sealed, except where the pipe goes through a wall or (obviously) a roof.

Any silicone with a 500 or above rating will be fine.

OK I was talking about the joint between the stove and first piece of vent pipe. I would like to seal it as the vent manufacturer and stove manufacturer recommends guess it was too much for the installer to do.

As noted above. Anything above 500* is fine. Seal that section well, as that's a positive pressure system and CO will leak out.

Did you smell or see smoke? Is that how you noticed it?

Please don't burn the stove until this is rectified!

Does it come in Strawberry flavor?

I dunno let me ask poopy. :D
