Why Smoke Comes Back in the room

If the chimney isn’t primed before you build the fire, that cold will block the warm air from rising up, causing “air sink”, which will push smoke into your house. … Open the damper and you will usually feel the cold draft fall into your fireplace or stove. Alternatively light very dry wood or paper gradually to slowly heat the hair, if this technique doesn’t work please call one of our chimney tech experts who will advice in all matters.
