*Note 1: If you purchase a product from an unauthorized PRO, 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 product yourself and your Rinnai product by ensuring that you only purchase Rinnai products from an Authorized Rinnai Dealer. View a list of Rinnai authorized online dealers.
