    Ruud High Effeciency 95% furnace Flue vent No cap????

    Hi I have a new Ruud H/E 95% furnace and noticed it was ran with a 3 inch PVC pipe for venting. My question is i noticed there is no cap on it. Wont rain get in there and get down in the unit and rust it out???? I asked the installer and he says it is supposed to be like that. Any experience with this and how this works? thanks

    That's fine. Rain just runs down the pipe into the drain system of the furnace. Keeps the trap full as a side benefit.
