I got a kick out of that, too. Like the "don't eat this" warnings on things that no one would ever eat. 😛 That control just feels cheap, and because of the way the water heater is designed there is no way to light it manually. It can ONLY be lit by that piezo lighter on the control. 😞 I can see the control going bad long before the water heater itself does. 😞 I'm used to the old, small water heater gas valve with the big black dial on it that has the temps. You reach in with a long match or one of those flexible, extended grill lighters to light the pilot while holding the button down, then put the access panel cover back on the inside, then the outside. Easy and long lasting. Heck, my water heater is approaching 18 years and it's still going strong. And it sits on a concrete slab on a dirt floor basement, so it's not exactly a dry environment. But, it's still fine. My furnace is about the same age, and other than replacing the hot surface ignitor a few times, it's still going strong, as well. They forgot to move the draft prover switch when they installed it in a horizontal position, so it was below the exhaust blower housing and would get water in it. It took a bit to figure that one out, as I'm not used to gas furnaces, but I knew what draft prover switches were and how they worked, and I could tell it was full of water from the condensation building up in the exhaust blower housing and running down the rubber tube to it. Just shook it out, let it sit for a few hours, and put it in the right position.
