FEATURES INCLUDE:
- Multiple venting options: The NCC199CDV can vent directly, using either 2-inch or 3-inch PVC or CPVC or rigid polypropylene. As mentioned, up to six units can be common-vented indoors or installed outdoors with an optional vent cap.
- Compact design: Weighing only 81 pounds, the compactly designed heater can be easily wall-mounted. Mounting brackets line up with the top of the unit, enabling installers to more easily position it on the wall.
- Racking capability: The ability to combine (rack) multiple units offers peace of mind through redundancy: If one unit requires servicing, the others can continue to provide hot water.
- Ultra-low-NOx, modulating Eco-Burner: The premix, fully modulating burner has a nitrogen-oxide emissions level of only 14 parts per million (ppm), far exceeding the South Coast Air Quality Management District requirement of 20 ppm. The burner optimizes the air/fuel ratio to continuously match energy consumption
