...it’s simple.
Navien’s next-generation condensing tankless technology
is designed to simplify every installation and oer the
best hot water experience. It eliminates the tankless
obstacles of the past, making it an ideal solution
for tank replacements. Simple retrot,
exclusive ComfortFlow™ technology,
ultra high condensing eciency
and now eld gas convertibility all
combine to make the new NPE series
easily the best choice in tankless.

It’s everything you need.
So much advanced technology in such a compact unit.
The NPE is a fully integrated system, designed to provide a high-
performance hot water experience.
High performance features make it easy.
Front Panel Command Center
A user-friendly interface on the front of
the unit makes it easy to set up the NPE,
run diagnostics and view essential system
information.
Outdoor Vent Cap (Optional)
NPE is designed for outdoor instal-
lation.
High Altitude Operation
The NPE is designed to operate up to
10,000 feet, ensuring maximum per-
formance in any region.
Leading Warranty Package
You can count on the NPE to reliably perform for years,
condence we back with extensive warranty programs
for both residential and commercial installations.
Utilizes Existing 1/2" Gas Line
The NPE is the rst tankless system that
can utilize a home’s existing 1/2" gas line,
for lengths up to 24'.
2" PVC Venting
Low exhaust gas temperature allows
for use of PVC, CPVC and Polypropylene
vent systems, signicantly reducing in-
stallation cost and hassle. The system can
use 2" venting for up to 60', often letting
the installer run a ue through the exist-
ing chase without requiring additional
holes.
Ultra Condensing Eciency
Navien’s condensing technology
delivers cooled exhaust gas and
high-performance. 0.95EF
Eliminates “cold-water sandwiches” and issues of
minimum ow rate. An insulated buer
tank and recirculation pump accelerates
hot water delivery.
Dual Stainless Steel
Heat Exchangers
Two stainless steel heat exchangers
provide longer life expectancy,
as they are highly resistant to
corrosion compared to copper
heat exchangers.
Field Gas Convertibility
The NPE’s negative pressure gas
valve and Dual Venturi system
allows for easy eld convert-
ibility from Natural Gas (NG) to
Propane (LP) operation.
Intelligent Preheating Technology
Recognizes hot water usage patterns
to intelligently provide hot water
when needed.
Simpler inside and out.
In comparison to other units the Navien NPE
is designed with simplicity in mind.
