I have obtained an older Ashley Wood Furnace (Model F8200) to be connected to my existing duct work. The blower runs continuously. I think it may be in the fan limit switch. I need a wiring diagram to show how the limit switch should be connected to the blower. I also have on the furnace, an automatic damper control with 2 wires coming out of that. I need to know where these 2 wires are to be wired in. I believe they are low voltage. I really need the wiring diagram. Any help or suggestions would be appreciated asap.
