The Robertshaw 712-020 Ignition Kit is a professional-grade intermittent pilot ignition solution designed for high-performance gas-fired heating equipment. This 24V non-lockout system utilizes advanced flame rectification technology to ensure precise automatic sequencing and safe burner operation. As a direct replacement for 3049-64, this kit is the industry-standard upgrade for systems originally equipped with the obsolete mercury flame sensor, which is no longer compliant with modern safety and environmental standards. The 3/4" x 3/4" combo gas valve features a built-in slow-opening regulator, providing soft ignition characteristics that reduce mechanical stress on the heat exchanger. This dual pilot ignition kit includes the robust 780-715 ignition module, offering a reliable solid-state logic interface for intermittent ignition devices (IID). With a factory-preset pressure regulator of 3.5" WC and a high-capacity rating, the Robertshaw 712-020 effectively streamlines furnace gas valve replacement jobs, ensuring consistent performance in demanding residential and light commercial applications. Key Benefits Direct Replacement for 3049-64: Engineered specifically to phase out obsolete mercury flame sensor assemblies with a modern, solid-state solution. Slow-Opening Gas Valve: Enhances equipment longevity by ensuring a smooth, controlled transition from pilot to main burner ignition. Enhanced Safety Logic: Features flame rectification sensing that immediately closes the main gas valve if the pilot signal is interrupted or drops below the required DC microamp threshold. Non-Lockout Operation: The 780-715 module provides continuous ignition attempts while demand for heat is present, making it ideal for standard ventilated heating applications. Universal Compatibility: Standard 3/4" NPT inlet and outlet connections allow for straightforward integration into existing manifold configurations for HVAC contractors. Common Questions Is the Robertshaw 712-020 compatible with LP gas systems? This specific model is factory-configured for natural gas. For LP applications, a conversion kit or a dedicated lockout model (such as the 712-006) must be utilized to meet safety codes. Does this kit eliminate the need for a mercury-filled capillary? Yes, this kit replaces the mechanical mercury sensor with an electronic flame rod and a flame rectification control module, providing a more reliable and environmentally safe ignition sequence. What is the maximum BTU rating for the 712-020 valve? The valve included in the 712-020 kit is rated for up to 350,000 BTU, supporting a wide range of large residential and commercial atmospheric burners.
