Rated 4 out of 5 by Not sure why, but this unit turned out to be the wrong one for our water heater, but we managed to make it work with a little yankee inginuity. Our old unit was completely flat on the bottom, where the pipes all connect, this one had a 1/2" projection where all the pipes connected. This set the pipes for the main gas line to the burner and the pilot, down that much in the opening, which had the new sealed cover over that opening. We managed to cut a slot in the cover to allow it to move down that 1/2" and align with the screw holes to secure the cover. It was touch and go for awhile, but we finally figured it out, cut the slot and it worked just fine. The unit lit right up after we replaced the thermocouple and the granddaughter and her family now have plenty of hot water. All's well that ends well. March 1, 2013
