Lennox 15Z66 Orifice Ring 22 I.D X 6 Medium

The Lennox 15Z66 Orifice Ring 22 I.D X 6 Medium is an essential component that requires high accuracy in the HVAC systems especially the gas furnaces. This orifice ring controls the rate of gas flow into the combustion chamber which ensures the better Proportions for fuel and air for combustion. The Orifice Ring has an inner diameter of 22 and a medium size specification; this makes it easy to meter the amount of gas to be used and also regulate the heat produced. Furnace efficiency is enhanced, fuel is saved and toxic gases are minimized by optimizing gas flow.
