basic question here: I can't figure out how to add more water into my furance. Its an old Sears furnace, and the water gauge looks rather low (about 3 inches below where the line says it should be). The furnace will not turn on today, and my guess is that the low-water cutoff kicked into gear. Is that a decent deduction? I'm a total newbie at this... any help would be greatly aprecaited.
There are two valves on the top and bottom of the glass tube showing the water level. I turned the top one, and nothing happened. I'm guessing the bottom one will drain water out, so i didn't try that one.
There seem to be two water pipes heading into the furnace with valves on them. But I'm not sure if I should turn one of these or not... don't want to screw anythign up.
Thanks again for any help.
