Lennox 17J65 Natural Gas Orifice

The Lennox 17J65 is an orifice for natural gas or propane, which is anessential part of gas-fired furnaces. It accurately stages the amount of natural gas that is allowed into the burner assembly in the general furnace. Thus, the regulated gas flow is optimal for combustion to maximize the heating efficiency in your furnace and at the same time minimize fuel wastage. It is possible to envision this component as a small guardian standing right inside the gas line of the furnace. It regulates the volume of gas supplied to the burners through variations on the size of the opening as well.
