    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 .

    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::F 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!
