Trane Intermittent Pilot Gas Valves

Overview

The TRANE FLS0005 is a 3-wire pilot burner assembly designed for use in gas heating systems. It serves as the ignition source for the main burner, generating a standing pilot flame that proves ignition to the gas valve through a connected thermocouple or thermopile circuit. This assembly is a direct OEM-style replacement component installed by licensed HVAC technicians and gas furnace service professionals during routine maintenance or ignition system repair. The FLS0005 is suited for residential and light commercial gas furnace applications where a standing pilot ignition system is in use. The 3-wire configuration supports systems that require separate connections for the pilot gas supply, thermocouple signal, and pilot adjustment or grounding function. It is typically found in older or mid-vintage gas furnace installations that rely on a continuous pilot flame rather than electronic ignition.
