Description
Lennox 18M6501 Gas Valve VR8205Q-2746 regulates the flow of gases to the burner by low and high-stage operation to achieve proper heating performance. It works on the concept of opening and modulating the flow of gas by control signals to enable the staged combustion to ensure better temperature control in HVAC systems like furnaces and heating units where two-stage operation is a requirement. It is installed in the gas supply line and is connected to the ignition system and the burner. Its use aids in controlled delivery of fuel, constant heat production and uniform operation of the system.
