We noticed that on the installation label of the water heater, the Date of Installation is shown as 02/04/18 rather than 02/04/19. We call the office the day after the installation and were told that the installer would stop by that evening and put a corrected label on the unit. As of 02/07/19, the installer has not returned to correct the problem. The label indicates that the unit is a year older than it actually is. Otherwise everything is ok.
