how to use the gas barbecue

Open the valve on the propane tank (located under the sink, first check if the valve is closed)
Press the start knob (first on the right) and turn to the left (you will hear a clicking sound)
Press each of the remaining three knobs and turn to the left, starting from the right-most knob
Each knob starts one grill section
To turn off the grill, the procedure is the opposite - turn the knob to the right into the 'off' position
After using the grill, make sure to close the valve on the propane tank
