Box of 1 Lampe Berger Catalytic Burner Wick Assembly. Always at the cutting-edge of technology, Maison Berger Paris presents its new burner for unrivaled performance! It's recommend that the burner and wick assembly be replaced every 200 lightings or once per year. To optimize the operation of the burner it is suggested that you clean it regularly (sometimes after repeated use it will turn black). Simply add SO NEUTRAL to your lampe and light the flame for 2 to 5 minutes until the burner turns grey again. Do not allow the flame to burn for more than 6 minutes.
