To light your Forney #61542 propane torch:
- Open the valve one turn
- Ignite the torch
- Adjust the flame
If you are having issues getting the propane torch to light and would like to test the piezo igniter (do not test the piezo while it is attached to the bottle), all you have to do is unscrew the brass tip and pull the trigger; you should see a spark. If it sparks, it will light.
