The Marey Power Gas tankless water heaters use a battery ignition system to activate their Power Gas models. There are 3 different sizes of the Marey Power Gas units and they are the GA5L unit, GA10L unit and the GA16L unit. The Marey Power Gas units run off 2 - D Cell batteries. The Power Gas units are activated through water flow which sends a signal to the batteries and then to the micro switch and activates the burners. The Marey Power Gas units require no electrical power to operate. The battery box is located on the bottom right hand side of the unit and is easily accessible.
