My tank's pilot and burner keep going out after warming up water. Not sure of the time it takes to shut off, but it is electric start, blue, strong pilot, burners fire on at the click, strong also. Then, maybe after 20 min or so, everything is off, and the process needs repeating. I cleaned the screen, checked the flue, apparently all are fine. I tried turning temp all the way up, and all the way down. Is this a thermostat problem or thermcoupler? Something else? Any ideas anyone?
