Rheem-Ruud AP13142-1 Damper Assembly

The Rheem-Ruud AP13142-1 Damper Assembly is a precision-engineered vent hood damper designed to regulate exhaust airflow and prevent backdrafts in gas water heater venting systems. Measuring 9 inches by 8 inches, this heavy-duty draft hood assembly is the direct performance replacement for the legacy AP13142 part number. In the field, technicians rely on this assembly to maintain the integrity of the combustion gas updraft, ensuring that toxic byproducts are effectively evacuated while protecting the heat exchanger from downflow turbulence. The integration of a durable vent screen within the assembly provides critical protection against debris and pests, which can cause pressure switch failures or flue blockages. For contractors managing commercial HVACR maintenance, installing this genuine OEM replacement part is essential for meeting rigorous safety codes and ensuring peak thermal efficiency in atmospheric and power-vented configurations.

Key Benefits:

• Precision Backdraft Prevention: Seals the vent ductwork during off-cycles to prevent cold air infiltration and heat loss.
• OEM Compatibility: Specifically engineered as the verified replacement for AP13142, ensuring exact physical fitment for 9" x 8" collars.
• Enhanced Gas Safety: Optimizes flue gas evacuation to maintain stable pilot operation and prevent combustion spillover.
• Debris Protection: Features an integrated vent screen to block outdoor contaminants from entering the water heater’s vent piping.
• Contractor Grade Durability: Built to withstand high-temperature exhaust environments in both residential and industrial applications.

Common Questions:

Is the AP13142-1 cross-compatible with older Rheem units?
Yes, the AP13142-1 is a direct functional and dimensional replacement for the discontinued AP13142 models. It maintains the same 9-inch by 8-inch mounting footprint required for standard vent hoods.

Does this assembly include the vent screen?
Correct. This complete damper assembly includes the housing, internal damper blade, and the protective screen necessary for a code-compliant installation.

Why is my current damper assembly failing to open?
Damper failure is often caused by mechanical binding or sediment buildup from combustion gases. Replacing the entire assembly ensures smooth articulation and reliable exhaust air regulation.
