A catalytic hand warmer gives off heat without an open flame. Fuel vapour oxidises on the platinum-coated mesh of the burner and releases heat. The warmer heats evenly and runs for 6 or 12 hours on one fill, depending on the model.
Filling
- Take the burner out of the warmer.
- Use the measuring cup from the set to take the right amount of fuel — it is marked for 6 and 12 hours.
- Pour the fluid slowly into the filling hole. It soaks into the filler inside, so there is no need to rush.
- Wipe off any excess and put the burner back.
Use Zippo lighter fluid only.
Lighting it
Hold a flame to the burner mesh for about 5 seconds, then take it away. No open flame appears — the mesh glows faintly, which means the reaction has started. Then put the warmer into the pouch from the set.
Using it
Carry the warmer in a pocket or in its pouch. Do not put it straight against bare skin and do not wrap it in thick layers — the burner needs air.
Switching it off
The warmer goes out by itself once the fuel runs out. To stop it earlier, take out the burner and put the warmer into an airtight bag — without air the reaction stops.
Safety
- Do not refill a hot warmer — wait until it cools down.
- Fill it away from open flame, in a ventilated place.
- Do not use it while sleeping and do not give it to children.
- Take care if skin sensitivity is reduced — prolonged contact can cause a burn.
