First, Thank You for your purchase, and welcome to the Xtreme family. An American owned and operated small business. There are a number of good reasons to register your Xtreme Heater, whether purchased directly from Xtreme, or from one of our many dealer and retail partners. Registration activates your warranty and lets us know who you are. Please note that this must be done with thirty (30) days of your purchase. If during the two-year warranty period, you happen to lose your proof of purchase receipt, we’ll already have you on file. You can learn more about the Xtreme Warranty here. As a registered customer, you will also receive occasional emails with tips and tricks as well as Xtreme specials. We will not sell or rent your email address, and you can opt out at any time. If you like your Xtreme Heater as much as we think you will, you can submit a testimonial and receive free Xtreme Gear!
