Carrier 1186104 Collector Box Gasket

Product Description

The CARRIER 1186104 is a collector box gasket designed to seal the flue gas collector box on residential and light-commercial gas furnaces. This gasket creates a pressure-tight barrier between the collector box and the heat exchanger or inducer assembly, preventing combustion by-products from leaking into the equipment cabinet or surrounding space. Licensed HVAC technicians install this part during routine maintenance, combustion leak diagnosis, or collector box replacement. Proper sealing at this joint is essential for safe furnace operation and for meeting applicable codes governing vented combustion appliances.

This gasket is suited for gas furnace applications where the original collector box gasket has deteriorated, torn, or compressed beyond serviceable limits. It is referenced in supplier data under the Heil and International Comfort Products equipment lines, indicating cross-brand fitment within those related equipment families. Technicians typically encounter the need for this part during heat exchanger inspections, inducer motor replacements, or any service call that requires removing and reseating the flue collector box assembly.

• Seals the collector box junction to prevent combustion gas leakage into the furnace cabinet
• OEM-style replacement gasket for accurate fitment and reliable sealing performance
• Designed for gas furnace flue collector box assemblies in residential and light-commercial installations

Installation Notes

Installation should be performed by a licensed HVAC technician in accordance with local codes and the manufacturer service manual. Shut down gas supply and disconnect electrical power to the furnace before disassembling the collector box. Inspect mating surfaces for debris or corrosion and clean thoroughly before seating the new gasket. Confirm all fasteners are snug and leak-test the collector box area with an approved combustion gas detector before returning the unit to service.
