Product Description
The ROBERTSHAW 712-005 is a combination gas valve with integrated 780-845 lockout ignition, designed for standing pilot ignition systems in residential and light commercial gas-fired heating equipment. Part of the Uni-Line 712 series, this valve uses flame rectification with solid-state logic and flame sensing to deliver automatic sequencing that ensures proper operation of an intermittent pilot ignition device. The 712-005 features a 0.5-inch inlet and 0.5-inch outlet, supports both natural gas and liquid propane, and is rated for capacities up to 170,000 BTU/h on natural gas and 272,000 BTU/h on LP. Licensed HVAC technicians are the primary installers for this component.
This valve is suited for a wide range of furnace applications where a standing pilot ignition system is required. The 712 series is engineered to accommodate multiple gas valve configurations, making the 712-005 applicable across a broad spectrum of gas-fired heating systems handling both natural gas and propane fuel sources. It ships with complete installation instructions and troubleshooting documentation, simplifying field service and reducing callback time. The series is available in multiple models to address capacity requirements up to 720,000 BTU/h depending on valve selection.
