Carrier 347318-754-CBP Collector Box Kit
For service technicians handling condensing furnace repairs, the Carrier 347318-754-CBP Collector Box Kit is the essential OEM replacement part for managing condensate drainage. This kit is the direct engineering successor to the 339707-754-CBP and is designed specifically for 35-inch tall, high-efficiency gas furnaces. Built from high-grade, heat-stabilized composite, this collector box assembly prevents condensate leaks and pressure switch tripping by providing a robust interface between the secondary heat exchanger and the inducer motor. Field failures often manifest as hairline cracks or warping, making this genuine Carrier part critical for restoring the negative pressure required for safe combustion. The kit includes the necessary collector box gaskets and mounting hardware to ensure a factory-spec seal, reducing the risk of carbon monoxide bypass and premature inducer failure. Precision-engineered for a drop-in fit, it simplifies furnace repair for technicians working on Carrier, Bryant, and Payne units where drainage integrity has been compromised.
Key Benefits for Technicians
- Direct Replacement: Seamlessly replaces legacy part number 339707-754-CBP with updated materials to resist acidic condensate corrosion.
- System Integrity: Restores proper pressure switch differential readings by eliminating vacuum leaks common in aged or warped collector boxes.
- Comprehensive Kit: Includes OEM gaskets and specialized fasteners to prevent bypass leaks and ensure a liquid-tight seal during reinstall.
- Broad Compatibility: Engineered for use across multiple high-efficiency condensing furnace models with 100k+ BTU configurations.
- Durable Construction: Heavy-duty composite material stands up to the thermal cycling rigors of modern HVAC heat exchange cycles.
Common Questions
How do I know if the collector box needs replacement?Technicians should inspect for visible hairline cracks, mineral deposits (white tracking) on the blower shelf, or chronic pressure switch codes. If the furnace fails to sustain a flame due to draft issues, the collector box seal or structural integrity is often the culprit.
Is RTV sealant required for installation?While the kit includes gaskets, factory guidelines suggest using a high-adhesion RTV sealant (such as Novaguard or G.E. 162) to provide a secondary seal against the heat exchanger panel, ensuring no flue gas or liquid escape.
Does this kit work for all 90%+ AFUE furnaces?This specific kit is designed for 35-inch cabinet "high-efficiency" models. Always verify the BTU input and cabinet width against the Carrier parts list to ensure the drainage ports align perfectly with your inducer and trap setup.
