Ademco Inc CQ100A-1013 Thermocouple 24 Inches 30mv

Product Description

The ADEMCO INC CQ100A-1013 is a 24-inch thermocouple designed for use in 30-millivolt heating systems. A thermocouple generates a small electrical current from heat at the pilot flame, signaling the gas valve to stay open. When the pilot goes out, current stops and the valve closes as a safety measure. This part is installed by licensed plumbers, HVAC technicians, and gas appliance service pros. At 24 inches in length, the CQ100A-1013 provides adequate reach for most standard appliance configurations without modification.

This thermocouple is suited for residential and light commercial applications running on 30-millivolt gas control systems. Typical installations include natural gas and propane-fired furnaces, atmospheric water heaters, and hot water or steam boilers. It is a direct-replacement-style component used during routine service, pilot outage diagnosis, or scheduled maintenance on standing-pilot heating appliances.

Key Features

• 24-inch length provides reach for standard furnace, water heater, and boiler installations
• Rated for 30-millivolt gas control systems
• Compatible with furnaces, water heaters, and boilers using standing-pilot ignition
• Sold individually as a single unit

Compatibility

Designed as a replacement thermocouple for 30-millivolt standing-pilot systems including gas furnaces, water heaters, and boilers. Confirm thread type and tip style match the existing gas valve and pilot assembly before installation.

Installation Notes

Installation should be performed by a licensed HVAC technician, plumber, or gas service professional in accordance with local codes and IFGC requirements. Shut off the gas supply and allow the appliance to cool completely before removing the old thermocouple. Thread the connection nut by hand first, then snug with a wrench — do not overtighten. Verify pilot flame engulfs the thermocouple tip fully after lighting to ensure proper millivolt output.
