Can a chimney have too much draft?

Too strong a draft can cause the heat to be sucked too fast into the chimney. Too strong a draft can be regulated with a damper, draft regulators (flue pipes or chimneys), or restrictors. Multiple uses of flue pipe elbows reduce the draft.

What causes draw in a chimney?

Warmer, lighter gasses in the flue tend to move upward. To keep the pressure conditions favorable, we need a tall column of warm air inside the chimney, and cooler air outside. The warm air will tend to rise, drawing the exhaust from the appliance out.

How do I improve the draw on my log burner?

Open the door on the stove while it's burning. Now open a window about 2 inches. If you see the flame or coals brighten, or smoke is pulled away from the door to the inside of the stove, you've improved the draw.

Wind Noises

A chimney balloon and a flue blocker are two fast and easy solutions. A chimney balloon is placed inside the chimney and is then inflated. It gets rid of the noise, keeps the cold air out and the warm air inside. A flue blocker works in the same way, except it's easier to install than the chimney balloon.

What is the 2 10 rule?

A chimney must project at least 3 feet above the roof on its shortest side and also be at least 2 feet above any roof structure that is within a 10 foot radius of the chimney. That's it. Following this simple rule helps to ensure other structures on the roof do not interfere with the exhaustion of combustion gases.
