Our 631 Series is perfect for homes with 1-3 showers. When properly sized, they provide an endless supply of hot water and are designed to be more efficient than traditional tank-type water heaters. With state-of-the-art gas combustion technology, our burners maximize output and provide temperature stability while maintaining low emissions.
Our OD units are built for outdoor installation only. These units require no additional venting accessories since a horizontal vent is built right into the unit.
Remote Controller (Optional on this heater)
Controlling your tankless gas water heater has never been easier. The multi-task remote controller utilizes advanced technology that allows you to adjust water temperature and other settings with the touch of your fingertip.
The user-friendly remote controller makes controlling the water heater as easy as 1-2-3. Anyone can use it.
A digital display on the remote controller unit displays the water temperature as well as the water level setting if you are filling up a tub. A red light indicates that the burner is in operation.
The remote controller is equipped with an alarm that will activate when you have reached the pre-set level of water volume in the tub. Once reaching the set level, the alarm will sound for ten seconds, reminding you to stop the water.
