1. With the lid off, hold the base unit with one hand and apply flame to the burner using a match or a lighter for 3 to 5 seconds using the other hand. Keep hands away from the match or lighter flame. The burner is catalytic so you will not see any flame on the burner.

2. Locate the orange indicator bar on side of lid. Touch indicator bar to the center of the burner 10 to 15 seconds. The burner has been ignited when color of the bar changes from orange to red. If the indicator does not turn red, repeat step 1.

3. After ignition has been confirmed, replace the Hand Warmer lid, then place warmer into the warming bag provided. You must place the Hand Warmer in the bag to prevent over-heating. Your Zippo Hand Warmer will now provide comfortable warmth for many hours but carefully follow the instructions regarding use. After ignition, heat is provided without flame by the catalytic unit.

4. If necessary to stop heating action, carefully pry off the burner element with pliers, a knife or edge of the lid. The burner element will be very hot. Do not touch it to the skin or any flammable surface. The burner and catalytic unit will then extinguish in about 30 seconds. When the burner and catalytic unit have cooled, replace the burner and lid. Be careful because there could still be fuel in the Hand Warmer.
