Thanks, I bought the home in 1992, first time home buyer, didn't know much. I recently replaced my dryer and was informed by the person installing it that it wasn't properly set up (it vents into my unfinished basement). So I'm going to fix it, but I was trying to figure out if I had been taken advantage of in '92.

Does anyone know when the residental code M1502.2 was enacted in Pennyslvania?
