Rheem-Ruud AP13156-1 Damper Assembly

The Rheem-Ruud AP13156-1 Damper Assembly is a 9-inch by 10-inch OEM replacement vent hood engineered for heavy-duty gas water heater exhaust management. This specific assembly serves as the updated, direct replacement for AP13156, providing a precise 9-inch diameter collar fit essential for maintainting systemic pressure. In high-demand HVACR applications, the vent hood damper assy is critical for preventing backdrafts from entering the ductwork, effectively isolating the combustion cycle from the ambient air of the facility. The assembly is designed to facilitate the consistent updraft of combustion gases, ensuring the reliable removal of harmful exhaust while the burner is active. Constructed for long-term reliability in thermal environments, this ProTech authorized part includes a integrated vent screen to prevent ingress of debris or pests that can lead to airflow restrictions and pressure switch failures. This component is compatible with select Rheem and Ruud commercial models, including the GX90 series, and comes ready for professional installation within standard venting configurations.

• Direct OEM Match: Fully replaces the legacy AP13156 model with no modifications required for 9-inch ducting and venting systems.
• Backdraft Prevention: Gravity-reliant or powered damper functionality prevents unconditioned air and exhaust gases from re-entering the building.
• System Efficiency: Optimizes combustion gas updraft, reducing stress on the burner assembly and improving total water heater throughput.
• Debris Protection: Built-in terminal screen blocks environmental contaminants and pests from entering the vent piping.
• Precision Dimensions: Features a standard 9-inch collar diameter by 10-inch housing for seamless integration into factory venting stacks.

Common Questions

Is the AP13156-1 a direct plug-and-play for the older AP13156?
Yes, the AP13156-1 is the factory-authorized superseding part for the original AP13156. It maintains identical mounting footprints and collar sizing for 9-inch commercial water heater venting.

What are the signs that a vent hood damper needs replacement?
Technicians should look for sticking damper blades, backdrafting into the utility space, or error codes related to pressure switch failures, which often indicate the vent hood damper assembly is not opening or closing correctly.

Does this assembly include the bird screen?
The Rheem-Ruud AP13156-1 comes standard with the protective vent screen to ensure the exhaust path remains clear of obstructions.
