The Lennox 11W01 is a vital component within your Lennox HVAC system known as a piston orifice assembly kit. This small but crucial part, weighing a mere 0.02 pounds, plays a significant role in regulating gas flow throughout your system. It functions similarly to a faucet, containing a precisely sized orifice (opening) of 0.071 inches in this case. By strategically controlling the amount of gas passing through, the 11W01 ensures optimal performance and efficiency. Typically found in gas furnaces and boilers, the orifice assembly kit works in conjunction with the gas pressure regulator. The regulator supplies gas at a specific pressure, and the orifice assembly meters that flow based on the designed size of the opening. This measured flow of gas is then mixed with air to create the combustible mixture that heats your home.
