I am installing an 80k btu Mr Heater in my pole barn. I decided to vent horizontally to avoid the "smoke stack" look through the roof. I purchased the horizontal vent kit from Mr Heater for this unit. The pipe is stainless steel with gaskets formed at each end, but I do not believe it is double wall.
I have a piece of b vent to compare to...
The pipe is also considerably smaller than the wall thimble, resulting in about 1/4 - 1/2 gap surrounding the pipe.
I put high temp caulk to fill the gap, then covered the joints with a storm collar for cosmetics.
I have read several threads all across the web regarding this, but it seems the common theme is its double wall b-vent. I'm not sure what I am missing...but I am not pleased with this kit. For $300, it should come ready to use. My question is will this be safe with single wall, stainless running through a wall thimble that provides approx. 1" clearance?
