Effective Limited Warranty Coverage
Navien products include a limited warranty covering parts, starting from the original purchase date.

Improper installation or use will void this limited warranty. The original purchase date must be submitted to Navien, and proof of the date must be provided upon request.

The end-user must pay for any and all shipping and handling charges and other costs of limited warranty service for the replacement part(s). Navien will repair or replace the covered product or any part or component (at its discretion.), that is defective in manufacturing for a period of up to two (2) years for parts and up to a limited warranty, subject to terms. If the product part is not available, Navien will, at its option, a) provide a suitable part or b) provide a credit in the amount of the then factory selling price for a new suitable substitute part to be used by the end-user towards the retail purchase price of a new Navien product.
