How does the Lacrosse catalytic burner works?

Fill the burner for 2/3 with the Lacrosse refill. A funnel is included. Place the wick back into the fragrance lamp and leave it for 20 minutes so that the oil well in the wick can pull, forget the CAP not on the lamp. Plug the connector of the wick and blow it after two minutes. Put the high open cap on the fragrance lamp and the aromatic scent is now spread through your home. Would you stop spreading the smell, then place the close cap on the wick and the Pebble goes out and spreads no smell more.
