It's not on the gas pump side.
Some people go into the trailer, turn off the fridge, in an abundance of caution, and turn it back on after leaving the pump.
It's not an open pilot flame, like the old days. It's electronic ignition, doesn't run all the time. And, as stated before, opposite side if the trailer. Furnace is also opposite side of the trailer, for us.
I've never run with the furnace going, as we winterize if we think lines will freeze.
