Lennox 79L57 Natural Gas Burner Orifice

The Lennox 79L57 is a natural gas burner orifice a small part of a whole system of a gas furnace. Located in the gas burner assembly it controls the flow of natural gas into the burner with desirable accuracy. This controlled flow makes certain that combustion is complete and thereby provides a supply of heat to your home. In combination with the gas pressure regulator the size of the orifice affects the performance of the furnace. An appropriately sized opening eliminates problems as inefficient combustion which leads to wasteful combustion of gas and poor heating. Although the given attributes can be probably left for the manufacturer’s reference, the Lennox 79L57 is specially developed to work with specific models of Lennox furnaces.
