TYPE NH - INSTANTANEOUS
Type NH heaters provide instant hot water without a tank and are used in applications where scaling is
prevalent and where hot water demand is fairly constant throughout the day, such as apartments, hotels, motels
and industrial applications. The Type NH heater should not be used on apartments and hotels with fewer than
30 dwelling units, nor should the heater be sized smaller than a 514.
Use a minimum 20' of 3" pipe on outlet.
