Carrier 335344-701 Vent Extension Pipe

The Carrier 335344-701 Vent Extension Pipe is a critical OEM replacement part designed specifically for Carrier, Bryant, and Payne induced-combustion furnaces. Engineered for precise exhaust gas venting, this factory authorized part ensures a leak-free connection between the furnace inducer and the external venting system. Measuring approximately 11.8 inches in length, this extension provides the necessary clearance and pitch for high-efficiency furnace models like the 58MXA series to safely expel combustion byproducts. As a veteran technician knows, maintaining the integrity of the exhaust duct assembly is paramount to preventing pressure switch errors and ensuring optimal airflow performance within the heat exchanger circuit.

Constructed from durable, heat-resistant materials, the 335344-701 is built to withstand the acidic condensate and high thermal loads typical of modern gas heating systems. Integrating this genuine furnace vent pipe into your repair or installation protects the system longevity and meets manufacturer specifications for air distribution. Whether you are addressing a cracked vent extension or reconfiguring a discharge duct on a Payne or Carrier furnace, this component provides the exact fit required for compliant and safe operation in residential and light commercial HVACR applications.

• OEM Precision: Guaranteed direct fit compatibility with Carrier, Bryant, and Payne systems, eliminating the need for field modifications.
• Enhanced Safety: Secures the ventilation system to prevent carbon monoxide leakage and ensure proper flue gas expulsion.
• Durable Construction: Engineered to resist corrosion from combustion byproducts, supporting long-term HVAC system performance.
• Technical Compliance: Meets CSAList criteria and manufacturer standards for induced-combustion furnace venting.

• Which furnace models use the 335344-701? This part is commonly used in high-efficiency gas furnaces, including the Carrier 58MXA and select Payne PG9 and Bryant 353BAV models.
• Will this solve a Code 31 or Code 34 error? While these codes often relate to pressure switches and ignition, a restricted or leaking vent extension pipe can trigger airflow faults; inspecting this pipe is a standard step in HVAC troubleshooting.
• Is a sealant required for installation? Technicians should follow the specific furnace installation manual; however, these pipes are designed for a secure mechanical fit to maintain exhaust integrity.
