Product Registration and Warranty*
AN IMPORTANT MESSAGE TO OUR CUSTOMERS: Rinnai Authorized Dealer and Warranty* Statement
Rinnai is firmly committed to providing its customers with best in class, reliable products through authorized dealers. Our policy is to honor product warranties and to perform services only on products purchased from an authorized Rinnai dealer and only accompanied by a receipt or proof of purchase. If you purchase a Rinnai product from an unauthorized dealer or if the original factory serial number has been removed, defaced or altered, your Rinnai warranty will not be valid.
Unfortunately, there are some websites and online dealers who claim to be authorized Rinnai resellers but are not. Products sold on these websites or from these online dealers do not carry a warranty from Rinnai. When you purchase products from an unauthorized website or online dealer you are taking a risk, because these products may be counterfeit, used, defective, or may not be designed for use in your particular installation. Please protect yourself and your Rinnai product by ensuring that you only purchase Rinnai products from an Authorized Rinnai Dealer.
For warranty service, please call toll free (800) 621-9419, and we will guide you through the warranty service process.
