Grand Canyon 18-inch Thermocouple

The Grand Canyon 1900-01H 18-Inch Thermocouple is a replacement safety thermocouple used in Grand Canyon control assemblies and pilot systems. This sensor sits in the pilot flame and generates a small voltage when heated, allowing compatible safety valves to verify flame presence and shut off gas if the pilot goes out.

Model 1900-01H is sold as a replacement part only. It is intended for use with approved Grand Canyon safety pilot and control assemblies that specify this thermocouple and should be installed and tested by a qualified gas technician following the burner and valve manuals.
