Check for local requirements. To have a gas water heater, you will need a supply of gas. If you are going to install gas piping or change the gas piping you already have, a separate gas-piping permit must be obtained. The gas piping must not block the removal of the tank. Always adhere to the manufacturer's installation instructions.
Pilot Models. Pilot model water heaters require you the owner to light the water heater pilot when you go camping. This works great and the only downfall is that it's kind of hard to do in the wind because the pilot can be blown out and require relighting. This system requires no 12 volt to operate.
