Lennox 23H11 Flue Gasket
The Lennox 23H11 Flue Gasket is a critical high-temperature seal designed specifically for Lennox G24 and G32 series gas furnaces. Also identified by part number 23H1101, this OEM component ensures a gas-tight seal between the inducer motor assembly and the flue collector box, preventing the hazardous leakage of combustion byproducts into the cabinet. When performing a furnace inducer motor replacement, reusing an old, compressed, or brittle gasket often leads to pressure switch faults or carbon monoxide leaks. This gasket is engineered from high-grade viton-based or silicone materials capable of withstanding the extreme thermal cycling inherent in high-efficiency heating systems. Proper installation of a fresh 23H11 flue gasket is essential for maintaining the static pressure required for the draft inducer to operate within manufacturer specifications. Ensure surfaces are clear of old adhesive and debris to ensure a flush, leak-proof Lennox HVAC part installation.
Key Benefits for Technicians- Direct OEM Replacement: Guaranteed fit for Lennox 23H1101, eliminating the need for universal gaskets that fail under high heat.
- Combustion Integrity: Secures the exhaust path to prevent nuisance trips of the furnace pressure switch.
- Thermal Resistance: Developed to maintain elasticity and sealing properties despite constant exposure to corrosive flue gases.
- Precision Die-Cut: Matches the specific bolt patterns of the Lennox inducer blower assembly for rapid field installation.
Is the 23H11 interchangeable with the 23H1101?
Yes, the 23H11 and 23H1101 are identical components. Lennox utilizes these part numbers interchangeably for the same flue collector seal.
When should this gasket be replaced?
This gasket should be replaced any time the inducer motor is pulled for service or if there are visible signs of scorching or degradation around the flue outlet.
Does this fit all Lennox G-series furnaces?
It is specifically designed for the G24, G24M, and G32 series. Always verify the model and serial number on the furnace rating plate before installation.
