NPE-Standard

Standard Navien advantages — durable stainless steel heat exchangers, convenient .” gas connections and 2″ PVC venting.

0.99 EF / 0.97 UEF ultra condensing technology (the industry’s top rated unit for energy efficiency).

  • 2" PVC venting up to 60'.

    No need to cut new chases. Low exhaust gas temps allows use of PVC, CPVC, System 636 and polypropylene vent systems, saving time and money

  • Field gas convertibility.

    Negative pressure gas valve and a dual venturi system allows for easy field convertibility from NG to LP operation.

  • Dual stainless steel heat exchangers.

    Resist corrosion better than copper to provide longer life.

  • 1⁄2" gas pipe capability up to 24'.

    Cut installation time, not new gas lines for retrofit applications.

Applications

  • Residential and commercial applications
  • Ideal for cascading with other NPE units
