Removing furnace from gas vent
I am removing a furnace from a gas vent.
What will be left is a residential water heater (typical 40MBH with 3" (I think) vent connecter) and 8" BVent up inside a house probably about 25 feet.
I am not clear about the rules. Is the 8" now too big for just the water heater?
But not too big if the vent connecter is 4"?
