Lennox 14C24 Cover

The Lennox 14C24 Collector Box Cover w/Gasket is a critical OEM replacement component designed to maintain the structural integrity and vacuum seal of your furnace's secondary heat exchanger system. Built for high-efficiency Lennox gas furnaces, this 14C24 collector box cover ensures that combustion byproducts and condensate are properly managed within the flue system without atmospheric leakage. The included gasket provides a precision fit, preventing pressure switch trips and combustion air loss that often lead to system lockouts during peak heating cycles.

As a veteran tech, you know that a warped or cracked Lennox furnace collector box can compromise the entire unit's performance. This genuine HVAC collector box cover (Mfr Part #: 14C24, also identified as LB-107333G) is engineered for broad compatibility with Lennox KGA092H4 series and over 300 other commercial and residential models. When executing a Lennox 14C24 installation, the robust gasket material handles the thermal expansion and contraction typical of high-static pressure environments, ensuring long-term reliability for your customers' equipment.
