20        Warranty

Effective

This 10/15 year limited pro-rated warranty on heat exchangers, 3/5 
year limited warranty on parts, and 1 year limited-labor warranty 
(“Warranty”) covers defects in materials or workmanship when the 
Navien NFB-C Boiler (“Product”) is installed by a properly licensed 
plumber or contractor, and installed in strict compliance with the 
Installation & Operations manual procedures, subject to the terms 
within this Warranty document. Improper installation or use will 
void this Warranty. This Warranty runs from date of installation and 
extends to the original purchaser and subsequent owners, but only 
while the Product remains at the site of the original installation. 
This Warranty includes both a limited and pro-rated warranty as set 
forth below.

What is covered?

Subject to the foregoing terms, Navien will repair or replace the 
covered Product or any part or component that is defective in 
materials or workmanship for a period of three (3) years in regard 
to parts and ten (10) years in regard to the heat-exchanger. Navien 
will pay labor charges for the repair subject to Navien’s prior 
written approval and in accordance with Navien’s schedule of 
approved labor allowances for a period of one (1) year from the 
date of installation. All repair parts must be genuine Navien parts. 
All repairs and replacements must be performed by an individual 
or servicing company that is properly licensed to do the type of 
repair.

: When the Product is or only has ever been used 

for anything other than commercial or multi-family residential 
applications (hereinafter “Residential”) then the parts warranty will 
be five (5) years and the heat exchanger warranty up to twelve (12) 
years.

During the applicable warranty period, replacement of the 
Product or components may be authorized by Navien only. Navien 
does not authorize any person or company to assume for it any 
obligation or liability in connection with the replacement of 
the Product or its components. If it is determined that repair or 
replacement of a part, under warranty, is not possible, the Product 
will be replaced with a new Product having at least the same BTU 
capacity as the product at issue. The replacement component or 
product will be warranted only for the unexpired portion of the 
applicable warranty period for the original component or Product.

The heat exchanger is covered by Navien’s pro-rated limited 
residential Warranty for defects in material and workmanship at a 
cost to the customer equal to a percentage of the Manufacturer’s 
Suggested Retail Price (MSRP), at the time the warranty claim is 
approved by Navien, as indicated in the following Coverage Table 
for Heat Exchangers Only. This pro-rated warranty only applies to 
the replacement of the heat exchanger and does not include labor, 
shipping, other parts, delivery or installation. In order to obtain this 
warranty, the customer must pay the applicable pro-rated amount 
as indicated in the following Coverage Table for Heat Exchangers 
Only. Once the customer pays the pro-rated amount, then Navien 
will ship the heat exchanger directly to the service provider.

How do I get service?

You must contact the original installer of your Product. Your 
installer will need to contact Navien to report the issue. If the 
original installer cannot be identified or you no longer choose to 
use that service provider, you may choose any service provider 
who is properly licensed to complete the necessary repair. The 
installer and/or service provider must comply with Navien’s 
warranty service and return policy procedures as available on 
Navien’s website including contacting Navien’s Technical Support 
Department at (800) 519-8794, option 2, prior to commencing any 
service.

Proof of the date of installation must be provided to Navien. At 
Navien’s request, the defective Product or part must be returned 
to Navien. When the Product is installed in new construction, the 
date of installation shall be established as the date upon which the 
end-user takes title to the real property. If proof of the installation 
date is unavailable, then six months after the date of manufacture 
will be used.
