Then I closed it and secured it properly and switch on my solenoid...turned on the gas and can see the pressure up....but no bubble or gas comes out!!

The solenoid is pretty hot at the back and I don't know where is the knob to turn to increase the flow rate...any bros got photo of the knob to turn?

Thanks!
