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 Group to the
latest edition of
ANSI 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 Gas Conversion Kit is 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 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 3â€
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†WC for 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 gallons for the
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-210S2 and NPE-240S2
models respectively), and a condensate collector. The NPE-180A2 model weighs 73 lbs (NPE-180S2 weighs 68 lbs), and the NPE-210A2/NPE-240A2 models weigh 77 lbs (NPE-210S2 and
NPE-240S2 weigh 73 lbs) and the NPE-150S2 weigh 62lbs. Unit(s) shall include features such as an adjustment for installations at high elevation, temperature lockout, and temperature
options from 97-120°F in 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°F intervals, 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 features such as flame sensor system, high limit sensors, 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) as compliant with Rule 1146.2 (Type 1) for Ultra Low NOx requirements of 14 ng/J or 20 ppm @ 3%
O2.
