Here is your at home tip for today. When you start a fire in the fireplace you should always try to make the fire as hot as possible. Use small amount of kindling and paper for a quick hot fire. This will warm the chimney to create a good draw and pull the smoke up the chimney. Sometimes the draw does not work as planned and smoke comes down the chimney and into the room. This is caused by negative air pressure. Turning off the cooking stove fan or bathroom exhaust fan can reverse this problem. If the problem persists, cracking the window ever so slightly will add fresh air in the mix and increase the draw up the chimney.
