Bummer Joe, at least you and Anna will be good. Sounds like something similar happened to us last Winter (a couple of months ago). The propane gas valve went out on the furnace - unit probably 15 years old. Had to convert the natural gas valve to propane. Somewhat a hassle, but done. In the meantime, fired up the second unit in the addition along with the fireplace and we were good. If all else failed - into the shop we go. Have had to do that during Hurricanes on occasion.
