Fire stop

[Joshua L. Frederick]

Is there any kind of fire stop or sealing required around the gap of furnace plenum/subflooring to the upstairs? Gas furnace is in a downstairs utility room.

Thanks in advance.

Not that I am aware of but it sure makes for a professional appearing install.

This is what a little pride in your work will look like not a requirement if your just grabbing the money and running,
