The Defender Safety System™ is engineered to be the safest, most reliable, maintenance-free, flammable vapor ignition-resistant system in the industry, claims the company. This system will be incorporated into the company’s 30-, 40-, and 50-gallon residential gas water heaters. It has ScreenLok™ technology, which is a flame-arrestor plate design. This component is made up of 18,000 geometrically oriented louvers to increase the velocity of incoming combustion air, states the manufacturer. In the event of ongoing flammable vapor burn inside the combustion chamber or restricted airflow, a thermal switch shuts down the burner and pilot. If this happens, the thermal switch can be reset.
