Atwood Mobile Products 96121 Electronic Direct Spark Ignition Water Heater - 6 Gallon;

All Atwood water heaters feature a patented "through tube" combustion chamber, utilizing the pilot flame to help maintain water temperature rather than losing this heat energy into the atmosphere. All units are lightweight and compact, with all controls accessible from the front for easy servicing. Many Atwood water heater models feature a heat exchange system in which the water from the vehicle's engine is piped to the water heater and then returned to the engine's cooling system. This option allows the water in the heater storage tank to be heated by the waste heat from the engine while driving allowing conservation of L.P. gas. All units come complete with door. Multiple protection features - Problems are prevented with the high temperature limit switch, thermostat, and pressure and temperature relief valve. An externally sealed combustion chamber keeps the outside of the unit clean.
