Question About Lennox International Inc. Furnace GUJ100D121B
can't find manual anywhere....

I've tried googling the model #. I've tried looking on the Lennox website and I can't even find the model # listed. The serial # is 8494m 21978. Any help would be great. We bought this house last May as a foreclosure, so there were no directions to anything.
