Robertshaw 1751-729 Ignitor/Sensor Assembly

The Robertshaw 1751-729 Ignitor/Sensor Assembly is a critical service component engineered for intermittent pilot ignition systems. Designed primarily for integration with the Robertshaw 712 Series Uni-Kit, this assembly functions as a reliable flame sensing and ignition point for gas-fired furnaces and boilers. It features a universal mounting bracket and includes all necessary hardware to streamline field replacement, ensuring a secure fit in various burner configurations. The unit comes equipped with 24-inch leads, providing ample length for routing through the cabinet to the ignition control module. Optimized for high-performance spark-to-pilot sequences, the 1751-729 is compatible with both natural gas and liquid propane (LP) applications. For technicians troubleshooting ignition lockout or inconsistent flame signals, this Robertshaw replacement ignitor offers the precise microamp feedback signal required by modern control boards to maintain safe combustion cycles.

• Universal Compatibility: Specifically designed to replace or upgrade components within the Robertshaw 712 series intermittent pilot kits.
• Simplified Installation: The inclusive mounting hardware and bracket tackle diverse burner mounting patterns, reducing time spent on the job site.
• Extended Reach: Durable 24-inch lead wires eliminate the need for splicing or extensions in standard furnace setups.
• Dual Fuel Rated: Reliable operation in both LP gas and natural gas environments without modification.
• High Signal Accuracy: Ensures stable flame rectification to prevent nuisance system lockouts.

Is the 1751-729 compatible with standing pilot systems?
No, this assembly is specifically engineered for intermittent pilot ignition (IPI) systems, specifically the 712 series, and is not designed for traditional standing pilot applications.

Does this unit support both heating and sensor functions?
Yes, the Robertshaw 1751-729 serves a dual purpose as both the high-voltage spark ignitor and the flame sensor for the pilot flame.

What is the maximum voltage for this ignitor?
This component is designed to operate within 24V AC control circuits as part of a complete spark ignition system.
