The Rheem PROG40S-40N-RH62 is a 40-gallon natural gas water heater from the Professional Classic Plus series, designed for residential applications requiring reliable recovery, durable tank protection, and consistent performance. This unit features a 40,000 BTU input and a first-hour delivery rating suitable for mid-range domestic hot water demand.
Equipped with an atmospheric venting configuration, the unit is compatible with standard vertical vent installations using B-vent. The model includes electronic gas control for precision temperature regulation and integrated diagnostics for streamlined maintenance. Its tank protection includes a durable glass lining and a magnesium anode rod to resist corrosion in potable water conditions.
The unit’s compact footprint and standard connections simplify installation in retrofit and new construction applications. Atmospheric venting requires a proper vertical flue and adequate combustion air. Installation must comply with local gas, plumbing, and mechanical codes. The model includes a factory-installed temperature and pressure relief valve and meets low-NOx emissions standards where required.
The PROG40S-40N-RH62 is a practical solution for residential installations where a moderate hot water load is anticipated. Its standard venting and gas input rating make it compatible with existing infrastructure in many retrofit projects. The electronic gas control and self-diagnostic capabilities assist in post-installation service and troubleshooting.
