Description
RUUD PRO+G40S-40N-RU62 is a 40 gallon short natural gas water heater.
This 40-gallon short natural gas tank water heater has a 40,000 Btu/h maximum input, 3/4" MIP hot and cold connections and a 1/2" gas inlet. It is an atmospheric vent model for 3" or 4" B-vent, and the manufacturer describes it as a Professional Achiever Plus unit with a Guardian System flammable-vapor shut-off.
Gas water heaters need a proper vent, combustion air and a gas line sized for the input, and natural gas and propane models are not interchangeable, so confirm the fuel type before ordering. Check the tank height and diameter against the space, line up the hot and cold connections with the existing piping, and have the installation follow the manufacturer's manual and local code.
