When we were full timing in our unit when it got down below zero it quit. I called a RV tech to come and and asked me if I was running it on AC. I was and he told me to switch to gas because it does better in cold weather. He told me cover the vent on the lower part leaving about 6 inches to allow air to the flame. I did that and everything started working and we did not have any problem even when it got down to -10.
