How do I avoid dry boiling?

Add water to the cup before assembling and lighting the stove. Fill to at least the minimum level marked in your cup, and no higher than the maximum fill line. Turn the burner off as soon as your water has boiled. Never leave your stove unattended while it's alight, so it can't boil dry.

How do I light my Jetboil safely?

CAUTION: Always ensure burner base is stable and free of any pot prior to lighting. Gas build-up can occur, resulting in increased flame eruption. Always follow the lighting instructions in your stove's manual. Open the gas valve only slightly and ignite straight away. Don't let gas run before lighting. If the stove doesn't light within a few seconds, turn the gas off and let any gas disperse before trying again. Light your stove outdoors, in a well-ventilated area, on a stable surface. watch video

No. The Flash only runs on isobutane/propane blend fuel and is designed to connect to Lindal-valve hiking canisters.

Boil a mix of roughly three parts water to one part white vinegar in the cup for a few minutes, then scrub off any residue with a non-metallic pad. A paste of baking soda and water also works well. Keep the cup out of the dishwasher, as it can damage the FluxRing, and never use powdered detergent, which may contain lye and damage the cup's surface.
