Even the use of a gas oven causes any problems extremely rarely. But many immediately have the question of the safety of such equipment, because "blue fuel" is explosive. > Hardly anyone wants to see their housing destroyed by a gaseous fuel explosion. To prevent such a tragedy, a device such as a thermocouple in a gas stove is used. It is the main element of the health monitoring system of the most popular gas appliance. 446-511 Gas Thermocouple Specification Wide Application Fits Robertshaw & some SIT 820 NOVA Gas Valves with fine thread, works on many fireplace Thread: M11x1 head, M10x1 end Thermocouple Length: 700 mm Temperature Resistance: Over 700℃ Part Numbers: 34820 446-511 72956 Advanced Features There are many advantages of thermocouples which will bring you a wonderful using experience. In gas stoves, the considered gas monitoring temperature sensors could last for a long time before replacement. 1. Simplicity of the device and the absence of breaking mechanical or burning out electrical elements. 2. Long term of operation. 3. High efficiency of flame temperature control. 4. Quick shutdown of gas. 5. Ease of replacement, which you can do yourself. 6. A thermocouple is the simplest temperature sensor without any electronic devices inside. There is nothing to break in it. It can only burn out from prolonged use. Installation > Do it yourself. Firstly, close the valve on the gas cylinder or methane line before any work can be carried out. Also, do not forget to switch off the power supply if it is designed for flammable devices. > The working end of the thermocouple is held rigidly near the burner or burners by a nut. If the working end of the thermocouple sensor is covered with limescale, then it must be cleaned with sandpaper or use solvent. The more carbon deposits there are, the less heat will reach the thermocouple and the correspondingly less electromagnetic field will be generated. The resulting millivolt voltage may not be sufficient to open the solenoid valve. > The second end of the thermocouple to the solenoid valve is connected with a threaded fitting or two crimp points. It does not seem difficult to remove them. The new thermocouple sensor is mounted in the same order - one end near the burner and the other end on the solenoid. **Before changing a damaged thermocouple in a gas stove, inspect the device for:** 1. The presence of carbon deposits on the working tip (if any, clean off with sandpaper); 2. Lack of burnout of this tip (in this case, only a complete replacement); 3. The rigidity of the connection of the contacts of the thermocouple sensor and valve (if necessary, tighten) 4. Serviceability of the thermocouple itself with emf when heated emf at a level of at least 15 mv. **Warm Tips: (Feedback of Customers)** 1. The gas valve threads are left-handed and the thermocouple is right-handed threads. 2. Before you purchase a new thermocouple, you need to determine the cause of the poor operation of the existing device- there may be a problem in the removed contacts on the valve, then you just need to tighten them. 3. To replace the thermocouple, you will have to remove the front panel from the gas stove, and also lift the top cover with rings on it. 4. There is only one significant drawback for a thermocouple - the difficulty of repairing the device. If the thermocouple sensor is faulty, then it is easier to replace it with a new one. 5. Do it yourself, carry out repairs and replace the thermocouple in the gas stove with your own hands only when the gas is completely shut off EASY INSTALLATION This gas log thermocouple is easy to install.
