The Robertshaw 712-006 Ignition Kit is a heavy-duty intermittent pilot ignition system designed for high-capacity natural gas applications requiring 100% shut-off safety. This kit features the 780-845 lockout ignition module, which utilizes flame rectification technology and solid-state logic to manage automatic sequencing. Equipped with a 700-056 gas valve, this setup offers a 3/4" x 3/4" IP connection and manages up to 350,000 BTU for natural gas. The module is configured for a 90-second trial for ignition, followed by a 6-minute purge delay if flame is not sensed. After three failed attempts, the system enters a 1-hour lockout period, making it ideal for units in poorly ventilated areas or indoor retrofits. Pros will appreciate the slow-opening gas valve feature, which ensures soft ignition at the main burner. This comprehensive Robertshaw 712 series kit includes the 1751-729 ignitor/sensor assembly and a specialized wiring harness for field conversion or OEM-style replacement in central furnaces and atmospheric boilers. Key Benefits High BTU Capacity: Rated for up to 350,000 BTU/HR on natural gas, supporting large residential and light commercial equipment. Lockout Safety Logic: The 780-845 module provides critical 100% shut-off protection if proof of flame is lost, preventing gas accumulation. Soft Ignition Performance: Built-in slow-opening characteristics reduce mechanical stress and noise during the main burner startup. Universal Field Replacement: Replaces a wide range of OEM pilot controls from brands like Carrier, Honeywell, and Rheem using the included hardware. Extreme Environment Tolerance: Rated for ambient temperatures from -40°F to 175°F, ensuring reliability in rooftop applications. Common Questions Can this kit be used with Liquid Propane (LP) systems? While this specific model is often configured for natural gas, it requires a specific LP regulator for propane applications. Always verify regulator settings before installation. How does the lockout timing work? The kit initiates a 90-second spark period. If no pilot flame is sensed after three trials (interspersed with 6-minute delays), the module locks out for one hour to clear residual gas. What is the primary difference between the 712-006 and the 712-016? The 712-006 includes the lockout module for added safety in restricted ventilation areas, whereas the 712-016 is a non-lockout version designed for well-ventilated natural gas applications.
