The needle valve is used to control the amount of gas flowing to the burner. The air valve controls the amount of air.
the air valve at the base of the burner
No, that is part of the function of the pilot light. To light the burner and to keep the gas valve open. The thermocouple sits in the flame of the pilot and produces a small electrical current that keep the gas valve open. When the tank cools down, the thermostat opens the valve to the burner so that it can light. When the pilot goes out, it is usually the thermocouple that is bad.
There will be a valve at the bottom of the Bunsen burner. Using a rubber tubing connect the valve to the regulator of the LPG cylinder.
Not sure what you are asking. The control valve on the front where you set the temperature controls the burner. The thermocouple that sits in the pilot flame let the valve open when heater needs to come on. The temperature sensor is in the tank and is on the back side of the control valve. All of these have their part to play in causing the burner to light and shut off.
If your main gas valve is stuck in the closed position, it must be replaced. This condition is the reason your thermostat will not cause the main burners to light.
