Now there's a classic. Make sure you label those pipes as ventilation, even though the manufacturer has not tested or certified them for that use. I know appliance manufacturers say it can be used, but I wouldn't unless the appliance monitors exhaust temperature. If not, you're playing Russian roulette with the gun held to someone else's head.

Common to use 3" PVC for intake combustion air and flue exhaust on condensing furnaces and boilers. Our house in Louisville built in 1994 had it and so does our current NY house.

I'm not sure if they made this reg to sell rolls of stickers, or because there have been cases of MA plumbers cutting a flue vent, adding a wye, and connecting a lav drain.....
