Burn candles in a well-ventilated but not drafty room:
Avoid burning a candle in an area effected by drafts, vents or air currents. This will help prevent rapid or uneven burning, sooting, and weak scent. If the candle scent is not as strong as you expect, you may have ventilation or air filtration systems diminishing scent throw.
In general, it is recommended that you do not burn candles for longer than four hours and cool for at least two hours before relighting.
Candles burned longer than four hours may overheat and create a fire hazard.
When lighting a candle, use long matches or a long-reach lighter.
Always keep your hair and loose clothing away from the flame.
