Gas fireplaces and fireplace inserts use thermocouples and thermopiles primarily to generate electricity. When turned on, the pilot in a gas stove generates heat, which travels through a thermocouple. As the heat reaches the second junction of the thermocouple, it generates electrical voltage.
How do you replace a thermocouple on a fireplace?

How big is the thermocouple on a gas heater?
All gas appliances with standing pilots, such as furnaces and water heaters, have a thermocouple. It’s a cylindrical probe about 4 inches long and a quarter to a half inch in diameter that’s attached to a 1- to 2-foot length of copper tubing. The probe is positioned next to the pilot opening so that its tip is in the flame when the pilot is on.
How to replace a gas flame thermocouple in a water heater?
