Stopping Back Draft

Back draft can have several causes. It is important to address and fix the back draft so that you can have a healthy, clean fire and smoke does not enter your sugar house.



Make-up Air Your building may be having trouble recovering the air that is being sent out of the chimney. Open a nearby window or crack an outside door slightly. Also, open the firebox door slowly.
Window As mentioned above, it can help to open a nearby window. However, wind direction will influence which window you should open. Make sure the air from outside is coming into the building to pressurize the room. In contrast, if the air from inside is flowing outside, close that window and open a different window on the opposite side of the building.
Fans If there is a fan running in a nearby bathroom (for example), this suction may be affecting the pressure in the room. Turn off any fans that could be creating negative pressure.
Cold Air If there is cold air in your chimney, it may be be falling downward and disrupting warm air that is trying to rise. Once the chimney warms up, the draft will correct itself and move upward.
Blockage If there is a cover on your smoke stack, make sure it is opened/removed. There could also be creosote/ash build up causing blockage.
Stack Height The general rule of thumb is that your stack pipe should be double the length of your pans, up to at least 12 feet of stack pipe.
Wood Stick to using well-seasoned, non-resinous firewood. Wet wood produces much more smoke and can not burn as hot/efficiently. If you see moisture bubbling out of the end grain of your firewood in the fire, that is sign that it is extremely wet.
Arch Blower Always make sure to turn your blower off before opening your firebox door.
