Description
The Lennox 18J15 is a Brown Inducer Orifice, a relatively small component of your Lennox furnace but it is vital. It is a nominally sized hole that regulates the availability of gas admitted into the burner assembly for efficient fuel combustion. Sited close to the burner this orifice is mainly used to control the proportion of air and gas for effective heating. Any defect in the orifice is likely to result in incomplete combustion, wastage of fuel, and in extreme cases failure of the system. It is easy to identify the product during the maintenance due to the brown color.
