<br /> 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
<br /> 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
<br /> 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
<br /> installed. (qty)NPE water heater(s)shall have a nominal flow rate capacity of GPM/GPH at-'F rise with rated input of BTU/hr.Water heater(s)shall be
<br /> 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"
<br /> 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
<br /> 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
<br /> 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
<br /> 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
<br /> and NPE-240S2 models respectively),and a condensate collector.The NPE-180A2 model weighs 73 lbs(NPE-I8OS2 weighs 68lbs),and the NPE-21OA2/NPE-24OA2 models weigh 771bs(NPE-
<br /> 210S2 and NPE-240S2 weigh 731bs)and The NPE-150S2 weigh 62lbs.Unit(s)shall include features such as an adjustment for installations at high elevation,temperature lockout,and
<br /> 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-I85°F in 1°Fintervals,for high
<br /> 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
<br /> 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
<br /> 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
<br /> 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
<br /> 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.
