Jim Katen Posted August 5, 2016 Report Share Posted August 5, 2016 House built in 1966. Horizontal furnace in the crawlspace, Model GS11Q4 120 Serial 465863J04 The old flexible brass gas connector is dated '64, but I think it was re-used from the previous furnace. This furnace looks, smells, and tastes like it's from 1978, but I can't resolve that with the serial number. It doesn't really matter because the thing is ancient, but I enjoy the hunt. . . Ideas?
