Installation 1. Valve installation unit should have the appropriate qualification and installation of the relevant gas pipeline construction specifications. 2. Valve should be installed in the indoor after the total intake valve for maintenance. 3. The valve body should be installed in the direction of the air flow, the valve coil can not be inverted, allowing horizontal and vertical installation. 4. Solenoid valve control line should be correct and reliable connection, the control line polarity: white line for the positive black line is negative, can not be reversed. 5. Pipeline purge, it is recommended to isolate the solenoid valve, so as not to damage the debris in the valve sealing material. 6. Pipeline in the test pressure test sealing performance, should first open the valve at the state of the solenoid valve. 7. Manually open the valve, should be in the valve inlet and outlet pressure balance operation. 8. Electric valve, avoid the wrong power supply, such as: the wrong polarity, the wrong voltage or long power, so as not to damage the electromagnetic coil.
When thermocouple heat, it will generate thermoelectri power, which make the magnet/solenoid valve work properly. Specific working principle for gas appliance as follows: When you press the knob, a small fire lit by its flame heating thermocouple, thermoelectric power generation. Thermoelectric power through the wire introducing electromagnetic coil generates a magnetic field pull the magnet/solenoid valve, the gas valve opens, the combustion passage is open, maintain its normal combustion. In the event of high winds or spill soup, etc., putting out the fire, the thermocouple power drops quickly to zero, the coil energized, magnet/solenoid valve failure, rapid reset in spring, the valve closes the gas path, terminate gas supply to ensure safety.
