Description
Rheem PROG40-36N-RH62-DV is a 40 gallon, 36,000 Btu/h Professional Classic® direct vent natural gas water heater.
This 40-gallon natural gas water heater is a direct vent model that uses outside air for combustion. The manufacturer describes an adjustable coaxial vent that can swivel 360 degrees and needs no electrical power, with an aluminum vent and cap base, and lists a 6" vent size.
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. The coaxial vent must be routed to an outside wall, so check the vent run before ordering.
