75 Gal. Tall Power Vent Water Heater, Heavy Duty, Residential, LPG, 75,000 BTU

Rheem Professional Classic Plus Series 75-Gallon LP Power Vent Water Heater – 75,100 BTU

The Rheem PRO+G75-76P-RH59-PV is a 75-gallon liquid propane water heater with an integrated power vent system, designed for high-demand residential applications requiring both high recovery rates and installation flexibility. With an input of 75,100 BTU/hr and a recovery rate of 72.8 GPH at a 90°F temperature rise, this unit is capable of supporting multiple simultaneous hot water draws.

This model utilizes a factory-installed blower for power vent operation, permitting up to 100 equivalent feet of venting using 2" or 3" PVC, ABS, or CPVC. It draws combustion air from the surrounding space and exhausts flue gases through a sealed system. A silicon nitride igniter, low-NOx burner, and self-diagnostic electronic gas control are included standard. The tank is internally protected by a glass lining and anode rod system for corrosion resistance.

Installation Requirements

This unit requires a 120V power source for blower operation. Venting should comply with manufacturer guidelines regarding slope, terminations, and maximum run lengths. It must be installed in accordance with local plumbing and gas codes, including proper condensate disposal if required. The use of a licensed professional is recommended due to the complexity of gas appliance installation, electrical requirements, and vent layout.

Contractor Applications

The PRO+G75-76P-RH59-PV is suitable for high-output residential systems where larger storage and fast recovery are needed—such as multi-bathroom homes or hybrid domestic hot water and space heating systems. The flexible venting capabilities and power-assisted combustion allow installation in locations where standard atmospheric models are not feasible. Integrated diagnostics, service-friendly controls, and compliance with low-NOx standards simplify jobsite installation and commissioning.
