Here is an old 1977 Lennox natural gas furnace tour. It is model # G8D2-82-3
I made a video previously just on the startup, this one is more comprehensive. If you have any old furnace questions, leave them below and I may be able to assist.
This furnace may not be too efficient but it seems to work quite well, it really puts out the heat. Modern furnaces are much more complicated and although efficient, there are more points to break and fail.
