Robertshaw 712-009 Ignition Kit

Designed for heavy-duty commercial and high-capacity residential systems, the Robertshaw 712-009 Ignition Kit is a complete intermittent pilot solution engineered for natural gas applications. This field-proven kit features the 780-845 Lockout Ignition Control, which utilizes flame rectification solid-state logic to provide 90 seconds of spark followed by a strategic six-minute purge cycle if ignition is not immediately achieved. For maximum safety, the module enters a one-hour lockout after three unsuccessful attempts, making it ideal for units in poorly ventilated areas.

The core of this system is the 7000 DERHC-S7C Gas Valve, a high-capacity unit featuring 1-inch inlet and outlet ports. It is factory-set with a 4.0-inch WC pressure regulator, though it is field-adjustable between 3 and 7 inches WC to meet specific site requirements. Rated for up to 720,000 BTU, this 24V intermittent pilot system ensures soft ignition characteristics through its built-in slow-opening feature, preventing hard starts and optimizing burner performance. This kit is the direct functional replacement for the obsolete Johnstone Supply L37-711 and is compatible with varied heating equipment requiring reliable automatic sequencing.

• High BTU Capacity: Supports natural gas systems up to 720,000 BTU, suitable for larger commercial furnaces and boilers.
• Safety Lockout Logic: Integrated 90-second lockout timing prevents excessive gas accumulation during ignition failure.
• Complete Setup: Includes a 24-inch ignitor/sensor assembly and a simplified wiring harness for efficient field installation.
• Operational Range: Robust design rated for ambient temperatures ranging from -40°F to 175°F.
• Flexible Piping: Standard 1-inch IP connections provided, with the ability to use reducer bushings for 3/4-inch applications.

Is the 712-009 compatible with LP gas?
This specific kit and its factory-set regulator are designed for natural gas only. Ensure gas type verification before installation.

What is the lockout sequence for this module?
The 780-845 control provides a 90-second ignition trial. If the pilot is not sensed, it initiates a 6-minute delay before the next try. It will attempt this cycle three times before entering a 60-minute lockout.

Does this kit include the pilot assembly?
Yes, the kit typically includes the gas valve, lockout ignition control, high-voltage lead wires, and the flame sensor/ignitor hardware required for a full system retrofit.
