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.

Frequently Asked Questions

Boil your water in the cup, then pour it into the meal pouch and follow the pouch instructions. Don't put food or pouches without water in the cup to heat them.

No. Fast Boil systems such as the Flash, Zip and Stash are designed for boiling water, not cooking food. They're perfect for coffee, tea, soup and rehydrating freeze-dried meals, but they aren't built for frying, simmering or cooking food directly in the cup.

Make sure the burner is cool and disconnected from the canister. Use a soft brush or cloth to clear debris or food from the burner head and surrounding area, keeping water out of the burner ports. If it needs more than a brush, gently use a mild detergent and water solution, then let it dry completely before reassembling.

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

Not always. The Flash 1.0L and Zip 0.8L use similarly sized burners, while the new TrailCook 1.2L and TrailCook 2.0L feature an integrated, self-centering pot-support burner that is not compatible with the Flash 1.0L or Zip 0.8L.

For our older models, the Flash and Zip share the same narrow burner, while the MiniMo and Sumo use a wider burner that is not compatible with the narrower cups.
