Robertshaw 712-008 Ignition Kit

The Robertshaw 712-008 Ignition Kit is a comprehensive solution designed to convert conventional standing pilot systems to modern intermittent pilot ignition. This professional-grade natural gas lockout kit features a high-capacity 720-070 actuated dual gas valve with a 1/2 inch x 3/4 inch IP configuration, supporting residential and commercial applications up to 200,000 BTU. The system utilizes flame rectification technology through the 780-845 lockout ignition module, which provides 90 seconds of spark followed by a strategic six-minute purge delay. If a pilot flame is not detected after three consecutive retries, the solid-state logic initiates a one-hour lockout period to ensure safety and prevent fuel accumulation. This HVAC intermittent pilot system maintains stable performance across an ambient temperature range of -40°F to 175°F, utilizing a slow-opening valve design for soft ignition characteristics. It is a direct universal ignition replacement for various Honeywell, Johnson Controls, and White-Rodgers applications.

• Universal Compatibility: Engineered to replace various OEM configurations from top brands like Honeywell and Johnson Controls, simplifying inventory for field technicians.
• Enhanced Safety Logic: Integrated 90-second lockout timing and 3-try retry sequence prevent hazardous gas buildup in the event of flame failure.
• High-Flow Capacity: The 1/2" x 3/4" gas valve accommodates systems up to 200,000 BTU, making it suitable for larger residential and light commercial furnaces.
• Soft Ignition Performance: The slow-opening valve mechanism reduces mechanical stress and noise during the main burner ignition cycle.
• Complete Installation Package: Includes the 720-070 gas valve, 780-845 module, spark/sensor probe, and full wiring harness for a seamless field conversion.

Can I use this kit for LP Gas applications?
While the included gas valve is factory-set for 3.5" WC Natural Gas, the kit includes an LP regulator conversion component to support Liquid Propane applications up to 320,000 BTU.

What happens if the system fails to sense a flame?
The module uses flame rectification to monitor the pilot. If the signal is lost, it will attempt ignition three times before entering a one-hour safety lockout.

Is the 712-008 a direct replacement for standing pilot furnaces?
Yes, this Intermittent Pilot Ignition System Kit is specifically designed to upgrade older, less efficient standing pilot systems to a more reliable electronic ignition setup.
