Description
The Copeland H06E-48 is a 48-inch replacement thermocouple designed for use in millivolt heating systems, including standing pilot furnaces, boilers, water heaters, and gas fireplaces that operate on 30-millivolt pilot safety circuits. The thermocouple functions as the pilot safety sensing device, generating a small millivolt signal from the pilot flame heat to hold the gas valve open. When the pilot extinguishes, the signal drops and the valve closes, preventing unburned gas from entering the heat exchanger. At 48 inches in length, this thermocouple accommodates installations where the pilot assembly and gas valve are farther apart, offering flexibility across a wide range of equipment configurations. The universal connection tip and standard threading make it a practical cross-reference replacement for many OEM thermocouples used in residential and light commercial heating equipment.
