In most case it's easiest to remove it from the regulator first. Make sure gas is turned OFF then unscrew the small nut holding the thermocouple pipe to the regulator. ( often a 10mm wrench), next look in and see if it's screwed similarly to the pilot pipe, or on a clip. Undo as needed, now gently pullout the entire thermocouple. If you buy a Honeywell Universal thermocouple it has parts for all popular makes and full instructions (for less than $10)
is the lines on the thermal coupler and pilot light for a hot water heater supposed to get hot
replace it if you don't have the time to clean it.
Thermal switch is to cut off the pilot ignition circuit when the heater temperature is beyond a set temperature. The thermal switch limits the temperature and protects the heaters

Make sure the thermal couple is postioned in the pilot flame correctly. It could be a bad gas control valve.
A thermocouple (or thermal couple) uses a principal called the Seebeck effect, where a voltage is generated in a conductor due to a temperature difference. Different metals generate different voltages, so by combining two different metals in the thermocouple, a voltage difference is generated between the leads of the thermocouple, proportional to the temperature difference. An example of one practical use of thermocouples is in controlling gas pilot lights: A "thermal couple" ( or "thermal coupling" ) is used to sustain a "pilot light" on a gas appliance e.g. a hot water boiler. The thermal couple is heated at one end by the pilot light and generates a small electrical charge that is passed down an internal copper filament to a valve in the gas supply. The valve remains open as long as the electrical current is present in order to supply gas to the pilot light. If the pilot light goes out or the thermal couple fails, the valve shuts off the gas. When you first light a pilot light, the thermal couple is usually heated by opening the gas supply by manually pressing a button and the gas ignited by means of say, a match. You maintain the gas supply by holding the button until the thermal couple heats up enough to generate the electrical charge that keeps the gas supply valve open to the pilot light.
it heats up the thermo couple which opens up the gas control valve allowing gas to flow to the main burner. if the pilot goes out the thrmo couple will cool and shut the gas valve so gas does not come out
I need to replace the pilot light on a superserve calor gas fire as the flame is blue on the bottom and yellow at the top
To keep the pilot up longer.
The pilot setting will heat the water a few degrees. A gas water heater will have a thermal rating in BTU of 30,000 to 80,000. The pilot light by itself will have about 1,000 BTU. Operating overnight with no water movement and a well-insulated tank, you will observe a temperature rise but certainly not enough for clothes washing, dishwashers, or showers.
High winds, pilot generator. Is the heater located next to a wall? Is the heater door closed? Does the heater have a draft hood or what they call a stackless heater? Ken
Have you turned the control from Pilot to On? Have you increased the temperature setting?
