    Wiring for older lennox furnace
    I have an older Lennox furnace that had some wires melted in a flash fire. Does anyone know where I might get the wiring schematics to rewire the unit? When I went to move the wires they broke apart and know I want to ensure that they are connected properly again. The model is G8R-120-1, serial 6377135372.

    Also, what is the way to ensure that this sort of flash fire will not reoccur.
    Thanks.

    Before you replace the wires you need to find the root of the problem. Wires just do not burn up for no cause.
