Lennox 28J94 Gasket
As a technician, you know that a compromised seal at the flue collector is a major liability for both system efficiency and safety. The Lennox 28J94 Flue Box Gasket is a critical OEM replacement part designed to provide an airtight, high-temperature seal between the flue pipe and the burner assembly. This 0.03-lb specialized Gasket is precision-cut to fit the Lennox 80MGF and 80UHG furnace series, along with select Lennox unit heaters. Engineered from heat-resistant composite material, it effectively prevents the leakage of combustion byproducts like carbon monoxide into the building. When you are pulling the flue box for maintenance or replacing a rusted collector, installing a fresh 28J94 Flue Box Gasket ensures you maintain the required static pressure and peak combustion efficiency. Do not rely on old, brittle gaskets that lead to secondary heat exchanger issues or safety shutdowns. This furnace repair part is the standard for securing the exhaust vent connection on high-performance Lennox heating units.
Key Benefits
- OEM Precision: Guaranteed Lennox 28J94 compatibility for a perfect fit on 80MGF and 80UHG series furnaces.
- Carbon Monoxide Safety: Forms a high-integrity seal to prevent dangerous combustion gases from escaping the flue box.
- High-Temperature Resistance: Durable composite material maintains its shape and sealing properties under extreme thermal stress.
- Efficiency Restoration: Eliminates air leaks that can disrupt the draft and lower the overall AFUE rating of the unit.
Common Questions
When should the flue box gasket be replaced?
Replace the 28J94 gasket whenever the flue box or inducer assembly is removed for service, or if you see visible signs of degradation, soot, or moisture around the seal.
Will this fit Lennox LF24 unit heaters?
Yes, the 28J94 is a standard OEM gasket for several Lennox unit heater models including the LF24 series; always cross-reference your specific model number.
Can I use high-temp silicone instead of this gasket?
Technicians should always use the OEM Flue Box Gasket to ensure the exact thickness and compression required for a safe, code-compliant seal.
