navien Premium Condensing is ideal for tank replacement

  • 2"PVC, CPVS, Polypropylene venting up to 60'

    Low exhaust gas temperature allows PVC, CPVC, and Polypropylene vent systems, significantly reducing installation costs.
    2" venting option allows for a flue to be pulled through the existing vent. No additional holes need to be drilled for venting.
    3" vents can be used to 150' with standard 2" X 3" adapters.

  • Better Adaptability to Gas Systems

    The Negative Pressure Gas Valve and Fan with Dual Venturi operation allows for better adaptability to low gas pressure applications. This industry leading technology makes it possible for the NPE to be installed with 1/2" Gas Lines up to24'.
    Easy residential tank replacements.

  • Field Convertible

    With the Negative pressure gas Valve and the Dual Venturi system, the NPE allows for easy field convertibility from NG to LP.

  • Ease of Installation

    With our mounting and bracket system we make it easy for only one person to complete the whole installation

  • Modular Design for Durability & Reliability

    Improved durability and reliability with the use of high quality engineering plastic(PPS) and reliable parts.
