My local Home Depot (in central MA) has pellet stove supplies including flue sealant. The package indicated that it was high temperature, high solids (fine silica) silicone glue. It also said that the metalwork needed to fit tightly and be secured with screws, (Probably because the sealant isn't relaible if there's a fire in the flue.)

RTV silicone sealer. If it can handle the exhaust from my race car it sure better handle the stove exhaust. And high temp comes in gold, red and black (iirc).

Someone else asked this yesterday, I get my high temp 600 deg RTV from Northline Express. In fact I get a lot of my burning supplies from them.

I have on occasion seen it at my local Home Depot, but it is hit or miss on whether it is actually in stock (not sure why). So I just ordered a few tubes and have spares now when I run out.

This is what I use and it's readily available from most car parts stores.
