I’m going to one floor then to the attic, do I need that sheet metal fire separation on the floor and ceiling of the first floor? Any other construction advice would be appreciated.
I dont think that a 6" stud will do it. The stud is 5 1/2"
The 3 " B gas vent pipe is about4+". You need a cut out from the wood on the floor and ceiling of 1" from the vent pipe . That makes you have to have a 6" hole for the vent pipe to go through the wood floor. yes you need a sheet metal fire stop here and at the ceiling line thats cut out just so the vent pipe goes through it tight. This also keeps the vent pipe that 1" away from the wood |
