  • Page 8: Installation Warning

    The appliance should be located in an area where leakage within the unit or at its connections will not result in damage to the surrounding area. Navien will not be responsible for any damage resulting from leaking if adequate drainage is not provided.

  • Page 9: Installation Warnings

    Installation Warnings: Protect against snow accumulation around the vent terminations. Ensure the exhaust pipe and the intake air pipe remain clear from obstructions at all times. DO NOT overtighten fittings as pipe and/or fitting damage may occur causing leakage. DO NOT install the combination Boiler where subject to vibrations. The vent for this appliance shall not terminate over public walkways, or near soffit vents, crawl space vents and other areas where condensate or vapor could create a nuisance, hazard or cause property damage.

  • Page 10: Getting Started

    Getting Started: CHECK THE RATING PLATE Navien units come from the factory configured for use with either Liquid Propane (LP) or Natural Gas (NG). Before starting the installation, check the rating plate (side of unit) of the combination Boiler to ensure the unit matches gas type, gas pressure, water pressure and electrical supply.

  • Page 11: Check Rating Plate

    Check Rating Plate Sample Rating Plate DO NOT install the Navien Combination Boiler in areas with excessive high humidity: DO NOT install the unit in a location where there is excessive high humidity such as a bathroom, damp crawl space and other areas such as this.

  • Page 12: Locating The Combination Boiler

    In addition, as with any water heating appliance, the potential for leakage at some time in the life of the product does exist. If there is no drain, Navien will not be responsible for any water damage that may occur.

  • Page 14: Plumbing And Water Connection Guideline

    Plumbing: Plumbing and Water Connection Guidelines The piping materials used should meet local codes and industry standards. Piping must be cleaned and flushed-out before installation. Do not apply torch heat within 12" of the bottom connections of the unit. Perform all solder connections at a safe distance from the (brass) male connectors below the unit.

  • Page 29: Gas Piping Guideline

    Use the charts on the following pages to properly size the gas supply line. The gas connection fitting on all Navien units is 3/4". DO NOT use less than 3/4" piping. When using flexible gas line, ensure the pipe’s inner diameter is sufficient to supply the required BTUs, also ensure that the flexible line has no crimps or tight bends as this will restrict gas flow.
