H/W tank burning up on propane?
Hot water tank (Suburban) seems to be "burning up" when I'm using propane. Usually I only use electric option but tried out propane option last weekend. Went out to back of trailer and opened the outside door to the H/W tank and very concerned with what I saw: lots of red embers where the flame (blue) seemed to reach the bottom of the tank. Next morning lots of ash buildup outside. Scary looking. Did a search and not much info. Any ideas what's up? Ash indicates something is getting burnt. Flame is blue, pretty large but what do I know. Tank heats up fine on electricity. Hope I haven't damaged the tank?
Clearly will not be using propane to heat the tank again. Will try to add some pictures as it's hard to describe.
