40 Gal. Tall Power Vent Water Heater, Residential, Gas, 40,000 BTU

Rheem PROG40-40N-RH67 – 40-Gallon Power Vent Natural Gas Water Heater

The Rheem PROG40-40N-RH67 is a 40-gallon natural gas water heater featuring a power vented exhaust system, making it suitable for residential applications where traditional vertical venting is not feasible. This unit is engineered for efficiency, performance, and straightforward integration into modern gas plumbing systems.

Product Overview

This model delivers 40,000 BTU/hr of input and supports a recovery rate of approximately 40.4 gallons per hour at a 90°F temperature rise. The unit is equipped with a factory-installed blower assembly for sidewall or vertical termination using 2", 3", or 4" PVC, ABS, or CPVC venting up to 100 equivalent feet. The design allows for flexible installation without sacrificing thermal performance or code compliance.

System Performance Highlights

• 40,000 BTU Input: Supports medium to high hot water demand with stable output capacity.
• Recovery Efficiency: Provides up to 40.4 GPH recovery at 90°F rise, minimizing wait time between usage cycles.
• Power Vent Configuration: Integrated blower permits extended horizontal or vertical venting with PVC/CPVC piping (up to 100 equivalent feet).
• Energy Factor: Rated at 0.67 EF under DOE 2015 test standards.
• Hot Surface Ignition: Electronic ignition system eliminates the need for a standing pilot, improving ignition reliability and efficiency.

Construction and Installation Notes

• Tank Construction: Glass-lined steel tank with anode rod for enhanced corrosion protection.
• Water Connections: 3/4" NPT top inlet and outlet for compatibility with standard piping arrangements.
• Dimensions: Approx. 67-3/8" height x 19-3/4" diameter; allow clearance for venting and servicing.
• Gas Type: Configured for natural gas; verify supply pressure and line sizing per manufacturer guidelines.

Installation Guidelines

Power vented units require access to 120V power for blower operation and proper combustion air ventilation. Installation should be performed by a licensed contractor familiar with power-vent combustion systems, as improper venting or wiring can lead to operational hazards or noncompliance with local codes. A condensate drain line may also be required, depending on ambient conditions and vent layout.

Professional Applications

For mechanical contractors, this model is suited for replacement of direct vent or atmospheric vent units in tight mechanical spaces or retrofit projects requiring extended vent routing. Its 40-gallon nominal capacity and moderate BTU rating serve 2–3 bathroom homes or light-duty multi-user applications efficiently. Electrical wiring and venting diagrams are available from Rheem technical literature to streamline installation planning.

Warranty and Compliance

• Warranty: 6-year limited tank and parts warranty (registration may be required)
• Certifications: CSA-certified; meets or exceeds NAECA and DOE 2015 efficiency requirements

Summary

The Rheem PROG40-40N-RH67 is a contractor-grade power vent water heater offering flexible venting, proven durability, and dependable thermal output. It’s an optimal solution for residential installs requiring reliable hot water delivery without direct vertical vent access.
