The Reliance 6-50-NBRT is a 50-gallon natural gas water heater with a 40,000 BTU burner and a tall 60.75-inch tank. It has a glass-lined tank, an anode rod, and a stainless steel flame arrestor for FVIR safety. The 0.60 energy factor and 88-gallon first-hour rating are modest compared with high-efficiency condensing models, but the atmospheric vent and millivolt gas valve keep installation simple and reliable. It suits households of three to five people replacing a standard tank, not homes needing sealed-combustion or mobile/manufactured-home installation.

This is a tall, 50-gallon natural gas tank water heater rated at 40,000 BTU. It is for indoor installation and meets NAECA 2015 efficiency standards. It has an energy factor of .60 and is CEE Tier I.
The tank is glass lined and wrapped in 1.5" of foam insulation. An anode rod protects against corrosion. The heat trap nipples are PEX polymer lined, and the dip tube is PEX. A T & P relief valve is installed, along with a stainless steel flame arrestor. The unit is FVIR approved, and air enters through the entire base of the heater.
A door-mounted manual reset temperature cut-off is included. The draft diverter outlet is 3" with an integrated adapter for a 4" vent. It is not for use in a mobile or manufactured home, and installing it in one voids the warranty.
