Rheem Professional Classic 40-Gallon Natural Gas Water Heater – 34,000 BTU, Atmospheric Vent

The Rheem PROG40S-34N-RH62 is a 40-gallon natural gas water heater designed for residential use where reliable recovery and space-conscious installation are required. With a 34,000 BTU/hr burner and a recovery rate of 34.3 gallons per hour at a 90°F rise, this model supports consistent hot water delivery for homes with moderate demand.

This unit features a short-profile tank, making it suitable for installations in locations with limited vertical clearance. It includes a push-button ignition system, electronic gas control with diagnostic LEDs, and a maintenance-free combustion air intake. The tank is glass-lined and protected with a magnesium anode rod to extend service life.
