The ProLine® Master Ultra-Low NOx water heater delivers reliable hot water while reducing environmental impact. These high-performance residential gas water heaters optimize efficiency with Intelligent Control Logic, ensuring precise sensing and a faster heating response. They use a Green Choice® Gas Burner to comply with ultra-low NOx emissions of less than 10 ng/J. ProLine® Master models protect the tank with a CoreGard™ anode rod, which features a stainless steel core for extended durability. Blue Diamond® Glass Coating resists corrosion, and a self-cleaning dip tube reduces lime and sediment buildup.
A push-button Piezo Ignitor makes lighting the pilot easy, while factory-installed heat trap nipples simplify installation. These water heaters save energy with eco-friendly insulation, heat traps, and a specially designed combustion chamber. Backed by an 8-year limited tank and parts warranty, the ProLine® Master Ultra-Low NOx water heaters actively provide long-lasting performance and peace of mind for residential applications.
