The Robertshaw 712-005 Ignition Kit is a field-proven intermittent pilot ignition system designed for natural gas heating equipment requiring a 1/2" IP connection. As a veteran-grade HVAC universal replacement kit, it integrates a 2000 IPER-HC gas valve with the 780-845 lockout ignition control, providing solid-state logic for precise flame rectification. This kit is engineered for reliability in furnace pilot ignition retrofits, handling capacities up to 170,000 BTU for natural gas. The logic-driven sequencing includes a 90-second spark cycle followed by a six-minute purge, with a safety lockout protocol that triggers after three failed attempts to sense a pilot flame. Built for the rigors of professional service, the 712-005 operates within a wide ambient temperature range from -40°F to 175°F, ensuring stable performance in unconditioned mechanical rooms. With factory-set 3.5" WC regulation, this Robertshaw 712 series kit simplifies the transition from standing pilot to energy-efficient electronic ignition in residential and light commercial applications. Key Benefits for Contractors Broad Compatibility: Functions as a high-efficiency intermittent pilot gas valve kit for diverse furnace and boiler models. Safety Lockout Logic: Features the 780-845 module with a 1-hour lockout reset to prevent hazardous gas accumulation. Flame Rectification: Utilizes advanced solid-state flame sensing to ensure the main burner only fires when a stable pilot is confirmed. Complete Installation Kit: Includes the gas valve, ignition control, and wiring harness to streamline field service calls. Common Questions Can the 712-005 be used on Propane (LP) systems? Standard documentation indicates this specific kit is factory-configured for natural gas at 3.5" WC. Always verify the specific orifice and regulator requirements if considering an LP conversion. What is the ignition sequence for this Robertshaw model? The system initiates a 90-second spark period. If no flame is detected, it enters a 6-minute purge before attempting a second and third trial, eventually entering a safety lockout if ignition fails. Is this kit a direct replacement for standing pilot valves? Yes, the 712 series is frequently used to retrofit older standing pilot systems to improve fuel economy and modern safety standards using the 1/2" IP connections.
