Does anyone know the formula for sizing flue pipe? I know that you can never reduce the flue size. But if you have more than 1 piece of equipment feeding into a single chimney, what is the formula for the chimney size? OR If you have 2 pieces of equipment feeding into a T-Y Flue piece, what size T-Y should I use?
