Stove Pipe Installation

Modern and vintage hand fired coal stove are similar to a wood stove and in some cases can burn either. They need to be regulated and fed by hand usually every 12 to 24 hours depending on your usage. They require no power to operate making them ideal for rural settings with long power outages.

Hello,

I'm working on installing new stove pipe for my stove. I have a 6" pipe that I'm connecting to the top of the stove. I've drilled holes and screwed it in but I notice a tiny gap between the outside of the new pipe and the hole in the stove. It's not that "perfect fit". Do I need to use furnace cement to seal off the first pipe section from inside of the stove? Or would air be drawn inward through the crack from the draft? This is my second year burning and fist pipe installation.

Any advice would be helpful. I don't want gases to be released from the gap

Thanks

ROB

I like to use furnace cement on any seam before the mpd and then high temp silicone after. The cement is hard to get apart later where as the high temp silicone is easy but it doesn't withstand very high temps.

Always found the cement works well for me, the pipe connections after the stove port for pipe to pipe fit are normally more than sufficient sealing surfaces.

Any amount of negative pressure (draft) in the pipe would insure that gases would not be able to leak out any cracks or connections in the pipe. BUT, in the event of a draft failure, having these leaks sealed would inhibit carbon monoxide from leaking into the stove room.
