The Lennox 56M40 is a 2-stage natural gas valve commercially used in different HVAC systems such as gas furnaces and boilers. It controls the supply of the natural gas to the burner and it works on two steps to meet the gas required by the burner for temperature control. The valve has a 24V electrical system and a maximum pressure of 3.5 Inches water column (wc); the 1/2-Inch valve is partially open for low heating requirements or fully open for high heating requirements. The first stage of this operation enhances the general efficiency by minimizing wasted energy in your home and also stabilizes the temperatures in your home.
