Too Small Chimney Caps or Chimney Pots

Common Wood Stove and Firplace Backdraft Smoke Issues

Why is smoke not going up my chimney?

The Flue Needs Priming

Smoke sometimes won't go up a chimney because there is a column of cold air in the chimney flue that pushes the smoke back into the home. It's important to check the draft before lighting a fire, to be sure priming isn't needed.

Does a taller chimney draft better?

Taller Chimneys Produce Stronger Draft

If draft problems are experienced with short systems, consider adding to the chimney height. If draft problems are experienced with systems higher than the recommended minimum system height, adding to the chimney may have little or no effect.

How do you stop a downdraft in a chimney?

Why is my house smoky when I use my fireplace?

A fireplace that kicks up smoke is a classic sign of a weak draft, which can result in a fire that quickly dies out or fire by-products “back-puffing”—getting backed up in the firebox or flue and issuing into the room as smoke and harmful vapors, including carbon monoxide.

Does a chimney cap Reduce draft?

However, did you know that chimney caps can also improve the draft in chimneys? Draft issues can contribute to smoky air and unpleasant odors entering your home as well as toxic gases like carbon monoxide lingering inside your chimney for longer than they safely should.

Should I crack a window when using fireplace?

Crack open a window nearest your fireplace

So rather than allow the air to come in from rooms far away from your fire (air that needs to get heated by your home heating system), if you slightly open a window as close as possible to your fireplace, this air can be heated by the fireplace itself.

Can snow block chimney?

Snow and ice can block chimneys and vents as well as clothes dryer exhausts.

How much draft should a chimney have?

In the heating industry, traditionally draft measurements around -0.02" w.c. are considered "low", and around-0.06" w.c. are "high" draft levels.

How do you warm up a cold chimney?

The most common way to warm your flue is by holding lit cardboard or pieces of paper inside your firebox, directly under the flue until the draft reverses to flow properly up and out of the chimney.

How do I stop the wind from blowing smoke down my chimney?

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 color should chimney smoke be?

The smoke coming out of your chimney should be almost colorless and thin. Thick, white or black smoke indicates that your fire is not receiving enough air. Woodstoves, fireplaces, and barbecues should be used in such a way as to minimize the impact on neighbors.

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.

Why does cold air come down my chimney?

The throat damper is a standard fixture in most chimneys. But its location just above the fireplace allows cold air to flow down much of the chimney even when shut. And although the damper is closed, warping or rusting can break its airtight seal enabling cold air to enter the fireplace.

How do you fix a chimney backdraft?

Try opening a window near the fireplace to increase airflow into the home before opening the fireplace door. The area will be exposed to more air, allowing for less to be immediately taken through the chimney. Also, consider using a fan or turning on exhaust fans to troubleshoot this problem.

Can a flue be too tall?

A chimney that's too tall can result in the heated air cooling off by the time it reaches the top of the chimney stack. This can create a negative pressure inside of the smokestack that pushes smoke and other gases back into the home.

Can a chimney be too short?

The column of rising hot gases inside your chimney will not be able to develop a safe and adequate draft. A chimney that is too short cannot vent correctly and can become a serious fire hazard to your home.

How high should a chimney be for a wood burning stove?

Chimney Heights and Termination

The minimum chimney height recommended for minimum performance of wood burning and multi fuel appliances is 4.5 m from the top of the appliance to the top of the chimney. It is best to position the chimney, so that it goes straight up as near to the roof ridge as possible.
