Propane heater and water heater-venting/exhaust
I'm wrapping up a renovation of a small cape cod style home. Early on we decided to convert to high efficiency propane heat and had that installed. We wanted to install a propane water heater, but don't have a place we can run a second set of pvc piping for intake and exhaust. Can we not split off the intake and exhaust inside the basement wall to run to both appliances?
