Robertshaw 1951-560 Thermopile

The Robertshaw 1951-560 Thermopile is a heavy-duty millivolt generator engineered for high-output performance in commercial and residential gas appliances. Featuring a 60-inch lead length and a threaded nut connector, this coaxial-style 750mV thermopile is a standard replacement for standing pilot systems found in commercial fryers, space heaters, and boilers. Built with high-grade thermocouple alloys, the 1951-560 ensures consistent millivoltage output to hold the main gas valve open under demanding thermal conditions. The threaded nut assembly provides a secure mechanical fit into the pilot burner bracket, minimizing vibration-induced signal loss. Designed for compatibility with various Robertshaw pilot burners and competitive brands, this pilot generator is the industry standard for technicians seeking a reliable gas valve power source. Its robust construction resists high-temperature oxidation, ensuring stable resistance values and long-term signal integrity in heavy-cycle applications.

• High-Output Performance: Delivers a consistent 750 millivolt signal to power millivolt gas control valves without external electricity.
• Extended Reach: The 60-inch lead length allows for flexible routing in large appliances and commercial cooking equipment.
• Heavy-Duty Construction: Optimized for the high-heat environments of commercial fryers and industrial gas equipment.
• Universal Connectivity: The threaded nut connection ensures a tight, conductive fit to standard pilot burner assemblies.
• Field Reliability: Reduces call-backs by maintaining a stable pilot flame signal even during fluctuating gas pressures.

What causes a millivolt drop in the Robertshaw 1951-560?
Millivolt drops are typically caused by carbon buildup on the element or loose threaded connections. Ensure the tip is fully engulfed in the top 1/2 to 3/4 inch of the pilot flame for maximum output.

Is this thermopile compatible with PG9 pilot burners?
Yes, the 1951-560 is a direct replacement for coaxial thermopiles used in various OEM and Robertshaw series pilot burners requiring a threaded nut mount.

Can I use this to replace a standard 2-wire spade connector thermopile?
This model uses a threaded coaxial connector. If your gas valve utilizes spade terminals, you will need the equivalent 2-wire lead version rather than the threaded nut style.
