What is “purging” or “burping” a torch?

Purging a torch is when you let out any excess air and/or butane from the torch. We recommend before every fill-up that your flip your torch upside down and press on the valve to release any excess air or butane (a ballpoint pen, mechanical pencil or a clean dabber works great). This not only gets the old butane out but also depressurizes the tank so that you can fill up your torch to its maximum capacity.
