  • Quick-connect system allows the installer to connect 2 units for increased hot water demands
  • Connect up to 6 units under the same controller system to meet even greater hot water demands
  • Direct vent (DV) models draw air from the outdoors so they do not use any air from the indoor installation location, making them ideal for tight spaces or where indoor air is unsuitable for combustion
  • Direct ignition means no standby pilot light to waste energy
  • Commercial grade heat exchanger and fully modulated burner work together to provide increased efficiency, to stabilize temperature fluctuations, and boost performance of the flow rate for long life under heavy use
