הלכה אויף שמות 31:9

If one forgot a candle on a board, one may tilt the board and the candle will drop – even if it is alight, as long as one does not intend to extinguish it. RAMA: It is preferable to use a gentile when it is not really necessary. (Kol Bo)This is as long as it is a wax candle or similar, or the oil is finished, but if it has oil inside it is not possible that the oil will not move closer to the wick, thereby doing Hav’ara (Causing a flame to burn). If it was purposely placed there, it is forbidden to tilt because the board is a Basis (something that upholds another article. The translation of kano (the leg) is the Basis of an article which is Muktze). RAMA: nevertheless, it is permitted to touch the board because one is not moving the candle. Likewise it is permitted to touch the candelabra in shul with the candles burning on it, as long as it is not moved. (Mordechai, Perek 22)
