*Available for"A2"models configured in an optional ComfortFlow recirculation mode. Energy consumption will increase when the system is
configured for recirculation.
Gas -fired, tankless, condensing, wall -mounted water heater(s) shall be direct vent NPE-2 Series models as manufactured by Navien, Inc. and are certified by CSA International to
the latest edition ofANSI standard Z21.10.3/CSA 4.3. Water heater(s) shall have a 15(5) year limited Heat Exchanger warranty and 5(3) year limited Parts warranty (8(5) year Heat
Exchanger and 5(3) year Parts for Commercial use) per Navien Limited Warranty. Unit(s) shall be designed to burn natural gas and can be for use with propane when a Field Conversion Kit is
installed. (qty) NPE water heater(s) shall have a nominal flow rate capacity of GPM/GPH at °Frise with rated input of BTU/hr. Water heater(s) shall be
vented with 2" Schedule 40/80 PVC/CPVC, approved polypropylene and stainless steel vent pipe at a distance not to exceed 75' (or equivalent) with each elbow equal to 8' of pipe length or 3"
Schedule 40/80 PVC/CPVC, approved polypropylene and stainless steel vent pipe at a distance of 150' (or equivalent) with each elbow equal to 5' of pipe length. Water heater(s) is rated for
150 PSI working water pressure and 300 PSI test pressure. Gas supply pressure shall be 3.5" to 10.5" WC for natural gas and 8.0" to 13.0" WCfor propane. Unit(s) shall have a steel case, dual
stainless steel heat exchangers, eco premixed burner, negative pressure gas valve, dual venturi, 3/4" inlet gas connection, 3/4" brass inlet/outlet water connections, water holding capacity of
0.6 gallon for the NPE-150S2, 1. 0 gallon for the NPE-180A2 model (0. 7gallonsfor NPE-180S2 model),1.2 gallons for the NPE-21OA2/NPE-24OA2 models (0.7 and 0.9 gallons for NPE-21OS2

temperature options from 97-120°Fin 1 °F intervals and 120-140°F in 1 °F intervals. The unit(s) shall include additional temperature options of 140-185°F in 1 °Fintervals, for high
temperature commercial applications. All NPE "A2"models shall include an internal circulation pump and 0.5-gallon buffer tank. The water heater(s) shall be controlled by an internal circuit
board that monitors the inlet and outlet temperatures with installed thermistors, sensing and controlling flow rate to set point temperature with air fuel ratio controls in order to maintain
thermal combustion efficiency. Unit(s) shall include safety featuressuch as flame sensor system, high limitsensors, overheat prevention device, freeze protection mode, and fan motor rotation
detector. Multi -system (cascade) applications that require 2 to 32 units shall be installed by connecting the units using cable only connections (Ready Link). The water heater(s) exceeds the
energy efficiency requirements of ASHRAE 90.1-2010 and is listed by SCAQMD rule 1146.2 (Type 1) for Low NOx that complies with 14 ng/) or 20 ppm NOx requirements @ 3% 02.
