I recently tried to start my LP gas furnace for the season, and couldn't get the pilot light to stay lit. It's an older model (Heil-Quaker model #NUGG100BA01) with a manually fired pilot. After some online investigating into usual suspects, I installed a new thermocouple (so much easier typing that than actually doing it- I actually had to drill the old one out of the brace!) and cleaned the pilot. Now when I attempt to light the pilot, the flame is about 4" long. This obviously scared the crap out of me, so I let go of the pilot button/switch. It went out right away. I tried it again and held it for about 45 seconds (to hopefully activate the thermocouple) and it still went out. With the pilot going crazy, I'm not very inclined to try it again. Before I installed the new T/C, the pilot light was at normal height when button/switch was held. There wasn't an unusually large build-up on the pilot before I cleaned it- I don't believe someone adjusted it up to compensate for a blockage (I'm not the original owner). For starters, I am not sure how to adjust the pilot light lower. Where are the adjusting screw(s) located? Secondly, is there something else I can check to find out why it isn't staying lit? It's getting colder and have too many other places for my few dollars to go right now! Any help would be greatly appreciated!
