By preventing the bypass of combustion gases and minimizing heat loss

Lennox 21W66 Gasket 326058-755 it is engineered to maintainThe Lennox 21W66 Gasket is a critical OEM replacement component engineered specifically for induced draft assembly sealing in high efficiency residential and commercial heating units. As a veteran tech knows, a compromised seal at the inducer motor lead to pressure switch trips and flue gas leakage. This draft inducer blower gasket (cross referenced as LB 106197) is designed to withstand high temperature combustion environments while maintaining a
