Tips: Operation instruction of gas solenoid valve

1. There are two ways to close the valve: An electric impulse of 1 sec (DC 9V), or Press the red knob (must open the protective cover first). After this operation，the valve remains closed. Note: the protective cover must remain on position at all time.
2. When the gas solenoid valves are closed, manually pull the red knob up to turn it on. Then the valve remains on. Note: the valve may not to be pulled up if gas pressure on both sides (inlet and outlet) is not balanced. Take necessary action to ensure that thy are balanced, then pull the knob up again, force pulling it may result in damage to the valve.
3. The solenoid valve will close automatically when it detects strong vibrations. Should this feature fails, notify the contractor or manufacture for repair.
