    WiI am trying to find the wiring diagram for a zone valve unit of a gas hot water hea
    The copper pipes are hot, the motor is running, but there isn't heat coming upstairs. I believe the wires to the zone valves are either disconnected or misconnected. It is and MAerican Standard unit that is at least 40 years old. Thank you so much!
