So I have a really nice woodstove in the cellar and run it allot during the winter as I spend allot of time in the mancave doing stuff.

Gets nice down there. Would love to get some of this heat up to the first floor. I leave the cellar door open and the heat travels up but not as good as I thought it would.

Been thinking of cutting a hole in the floor and putting in a register but I am sure that is not allowed code wise for fire stop etc. But what if this was a register vent with an auto fire damper fusible links in it.

So any of you builders / HVAC guys know what the rules and code is for a hole in a floor between levels. Can it be done or not?
