2. Tirrill (Bunsen) Burner

3. How the parts work. Turning the barrel Controls type of flame (orange or blue) by opening and closing the air vent. Always use blue flame (open vent); however, vent should not be wide open for initial igniting.

4. How the parts work. Gas Flow Control  Controls the height of the flame through controlling the amount of gas flowing.  Use appropriate flame height. NO TORCHES.

5. Operation of the Tirrill (Bunsen) Burner  Hook the hose to the gas inlet and gas jet  Place spark ignitor next to top of barrel  Turn on gas and ignite with sparker  Make barrel and gas flow control adjustments for proper flame

6. Trouble Shooting  You should be able to hear the gas flowing. If not:  Check if gas flow control valve is open  Check if jet valve is clogged. If so see your teacher.

7. Troubleshooting  Gas attempts to light but goes out. Possible causes are:  Air vent is to far open. Turn the barrel down.
