I noticed some smoke coming into the room after the CSL stopped burning. Why?
Although this rarely occurs, it only will happen if your chimney cools too much after the flames have gone out, which may allow a downdraft, forcing air back down the chimney. This can happen with any type of fire. If this occurs, you want to get an updraft restarted so we suggest adding some newspaper to the firebox, carefully light them and the heat should start the air flow back up the chimney. To avoid this problem, we suggest you burn CSL on the hot embers following a regular fire.
