My 2011 347THT Montana Mountaineer has a
Suburban SW10 DE hot water heater.
I can't tell if runs off propane or electricity, or propane only. The label (see pic) says "For Use With Propane Gas"
What is the ON/OFF switch outside on the hot water heater itself for?
What is the ON/OFF switch inside the RV on the control panel for?
I've just turned both switches ON and after a couple tries, the propane ignites and I get hot water and haven't thought about what each switch is for or if I have electric heating or not.
