Description
The Lennox 10P33 Dual Main with Natural Gas LP Kit is a type of gas pressure regulator valve that is used in residential and commercial HVAC systems. This makes safe and efficient use of gas-fired appliances by controlling the pressure of natural gas or Liquefied Petroleum (LP) gas that is supplied to the appliances. The pressure of the valve does not change with the pressure variations that may occur from the main gas line. This Lennox valve is normally placed ahead of the appliances that are powered by gas as shown below.
