It's been my observation that most refers that break boilers run mostly on electric. However, according to Dometic, a flame needs to be present for it to go up in flames. So for that reason, it's safer to limit refer operation to electric (running it exclusively on electric increases the chance of breakage, but limits the chance of fire).
It's my understanding that the ones that have burned developed stress patterns while running on electric, then finally broke while running on gas. Stress patterns are the areas that become overworked as a result of expansion and contraction. Once these patterns are set, these overworked areas will continue to flex more regardless of operation mode(and BTW there's no practical way to tell if you have stress patterns or not). So even if you stopped running it on electric and started using it on gas only, these stressed areas will still flex more then the unstressed areas because they are in a weakened state. If your refer has only been run on gas, then it most likely won't have these stress patterns and it's much less likely to break. It's the ones that run all the time on electric that I see failing.
