Problem & Solution: Propane furnace not working when temperature got down below freezing. Had this problem for 6 years. Two heating companies and Propane company could not figure the problem out. Mr. Misner writes: “The problem was that my propane furnace would quit working and by the time the service man arrived it was working again and since no one could find the problem I depended on my fireplace insert for most of my heat. I live in Southwest Missouri and for the most part our winters are fairly mild. With temps during the day normally above freezing and dropping below at night. Then this last time I was checking the furnace (10-13-2009). I noticed that there was no LPG odor so I went online and came across this web-site: www.propane101.com . This problem was not only overlooked by a house inspector when I purchased my house but by two furnace repair men and two different propane companies. I bought a used propane tank last year and the propane company who installed it missed this. I had a two stage LPG regulator system (one regulator on the tank and the other one on my outside furnace). The second stage regulator was not installed properly. It was installed horizontally with the vent facing slightly up (on the regulator it says if installed with no cover the vent is to face down). When it would get below freezing the moisture in the regulator would freeze the regulator shut and not allow propane through. I understand that it can also freeze open. I thank God that the regulator did not freeze open (cause and explosion) and I thank you for listening to God’s calling. I hope you will add the web-site: www.propane101.com to your web-page and inform people of the proper installations of regulators. By the way my tank is 35 feet from my house and my furnace is the only thing that uses propane so I changed to the integral twin stage system and last night it was just below freezing and it worked. THANK YOU!” Thank you Mr. Misner! Your information is very valuable for the safety of other people that use propane gas!
