Important: To get the most out of your warranty, a Warranty Registration Form must be completed at time of start-up by the installer. Please note: If this form is not submitted to National Comfort Products, our standard warranty period will begin at date of original sale, whether or not actual use begins on that date.
If you are registering multiple units, please contact the factory at 800-523-7138.
