Lennox 79L57 Natural Gas Burner Orifice

The Lennox 79L57 is a natural gas burner orifice, a small but crucial component within a gas furnace. Installed in the gas burner assembly, it precisely regulates the amount of natural gas entering the burner. This controlled flow ensures efficient combustion, leading to consistent heating throughout your home. Working in tandem with the gas pressure regulator, the orifice size directly impacts the furnace's performance. A properly sized orifice prevents issues like incomplete combustion, which can waste gas and reduce heating efficiency. While the listed specifications (length, width, height, weight, and voltage) are likely for reference purposes only, the Lennox 79L57 is specifically designed for compatibility with certain Lennox furnace models.
