<br />(ias precl, 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 Group to the latest edition of
<br />ANSI Standard Z21.10.3-CSA 4.3. Water heater(s) shall have a 15(5)-year limited Heal Exchanger warranty and 5(3)-year limited Parts warranty (8(5)-year Heat Exchanger and 5(3)-year
<br />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 Gas Conversion Kit is installed._____(qty)-
<br />NPE water he.ater(s) shall have a nominal flow rate capacity of______GPM/GPH at______"Prise with rated input of BTU/hr. Water heater(s) shall be vented with 2" Schedule
<br />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/
<br />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
<br />pressure and 300 PSI test pressure. Gas supply pressure shall be 3.5" to 10.5" WCfor natural gas and 8.0" to 13.0" WC for propane. Unit(s) shall have a steel case, dual stainless steel heat
<br />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 gallons for the
<br />NPE-150S2,1.0 gallon for the NPE-180A2 model (0.7 gallons for NPE-180S2 model), 1.2 gallons for the NPE-210A2/NPE-240A2 models (0.7 and 0.9 gallons for NPE-21052 and NPE-240S2
<br />models respectively), and a condensate collector. The NPE-180A2 model weighs 73 lbs (NPE-18052 weighs 68 lbs), and the NPE-210A2/NPE-240A2 models weigh 77 lbs (NPE-210S2 and
<br />NPE-240S2 weigh 73 lbs) and the NPE-15052 weigh 62lbs. Unit(s) shall include features such as an adjustment for installations at high elevation, temperature lockout, and temperature
<br />options from 97-120°Fin 1°F intervals and 120-140°Fin rFintervals. The unit(s) shall include additional temperature options of 140-185°F in rFintervals. for high temperature commercial
<br />applications. All NPE "A2" models shall include an internal circulation pump and 0.5-gallon buffer tank. The water heater(s) shall he controlled by an internal circuit board that monitors the
<br />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
<br />efficiency, l)nit(s) shall include safety features such as fame sensor system, high limit sensors, overheat prevention device, freeze, protection mode, and fan motor rotation detector. Multi
<br />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
<br />requirements ofASIIRAE 90.1-2010 and is listed by SCAQMD Rule 1146.2 (Type 1) as compliant with Rule 1146.2 (Type 1) for Ultra Low NOx requirements of 14 ng/J or 20 ppm @ 3% 02.
