I live in a mobilehome and I have a 6 month old GAS water heater
outside. I thought the water heater ONLY comes on when you use the HOT
water. I heard it come on this morning at 5:00 AM(it was really cold
outside) do not know if that makes a difference. It stayed on for 15
minutes. Is this normal? thanks

Assuming it is a tank type, this is perfectly normal. The heat will
radiate out of the tank even if you are not using the hot water, so the
gas burner will need to kick on 1-2x a day to keep it hot for when
you're ready to use it.
