Weil McLain 510-811-646 LP Pilot Assembly Kit W/Orifice

The Weil McLain 510-811-646 Pilot Assembly Kit with Orifice is used to aid controlled burner ignition within gas-fired heating equipment in HVAC systems. The liquid propane is directed through a measured orifice creating a constant pilot flame that starts the main burner each time a heating cycle begins. It has pilot tubing, ignition elements and a coinciding orifice, which connects to the gas supply and burner section that is used in HVAC systems. It is placed next to the burner assembly in the combustion chamber and is used to provide a stable source of ignition in the system.
