Inquiry (采购产品): PVC Cellular Gas Vent Spec's I'm having problems with a State ( MI. ) Mechanical inspectors, concerning PVC Cellual core exhaust venting on a 60,000 BTU wter heater. He clams he needs the PVC piping spec's to show that the PVC will handle the heat temp from the water heater. I have instatalled a Bradfrod white water heater and can get no one to provide the information. Can you help or provide info to any one that can? Thank You for your time. **** Hidden Message ***** Phil Shaffer 49345 Company: Shaffer Machanical E-mail: pshaffer@wmis.net **** Hidden Message ***** pshaffer@wmis.net
