What is covered under the Navien Warranty?

Navien products are accompanied by a limited warranty that encompasses labor, parts, and the heat exchanger. These warranty periods commence from the original installation date. It is imperative to provide Navien with the original installation date, and upon request, furnish proof of this date. In the event that a component (either part(s) or the heat exchanger) fails under normal use and service during the specified warranty period, Navien, at its attention, will replace the defective component. The replacement component must be an original factory component from Navien. Additionally, Navien may choose to replace the product with a new or refurbished one of similar quality and design, depending on its sole discretion. The warranty coverage for the replacement component or product will be applicable for the remaining duration of the original component's warranty period. For labor expenses associated with warranty service, prior written approval from Navien is required, and the payment will adhere to Navien's approved labor allowances schedule.

  • 1-year warranty for labor

  • 3-year and 5-year warranty for parts

  • 5, 8, 10, 15-year warranty for heat exchangers

What is NOT covered under the Navien Warranty?

Navien's Limited Warranty becomes null and void under certain circumstances. These include the purchase of the product through internet channels, e-commerce platforms, or from installers who obtained the product from unapproved suppliers or distributors not authorized by Navien. It also covers improper installation, such as failure to strictly adhere to the Installation Manual procedures, installation by an unlicensed installer, or any installation that violates applicable regulations, laws, or building codes. Neglecting regular maintenance, misuse, operation at settings contrary to recommendations, failure to comply with instructions in the User's Operation Manual, or making any modifications or alterations to the product, like component removal, the addition of non-approved components, relocation from the original installation site, or any accidental or intentional damage, all void the warranty. Using the product for non-recommended purposes, damage caused by local adverse conditions, gas flow problems, electrical surges, flooding, fire, extreme external temperatures, or any other causes of damage unrelated to manufacturing defects are also excluded. The installer's failure to fully comply with the Warranty Service and Return Policy procedures provided by Navien, including the requirement to contact Navien Tech Support while in front of the product for troubleshooting, results in warranty voidance. Using the NPE Series Water Heater for space heating purposes only will also void the warranty. Performance issues stemming from improper sizing, gas supply, venting, combustion air, electrical specifications, wiring, fusing, or any other components or specifications are not covered. Attempting to convert the water heater from natural gas to LP gas, LP gas to natural gas, or operating it with an unspecified gas type also voids the warranty. Damage, malfunctions, or failures due to abuse, negligence, alterations, accidents, fires, floods, freezing, wind, lightning, or other natural disasters are not covered. Operating, using, or storing the water heater in corrosive or contaminated environments, running it at temperatures beyond factory limits, exceeding the high limit control's maximum setting, operating without a continuous supply of potable water, or subjecting the heat exchanger to pressures or firing rates outside the rating plate specifications all lead to warranty void. Additionally, installing the water heater outside the United States and Canada or removing or altering the rating plate will void the warranty as well.
