Why is there smoke coming out of the chimney?
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.
Should I see smoke coming out of my chimney?
Wood stoves and other appliances that have pipe chimneys can experience chimney fires, too. If you can see heavy smoke, light, or flames coming out of the cracks between the sections of chimney pipe, call 911!
What color should smoke be coming out of chimney?

How can a chimney catch fire?
Chimney fires occur when creosote buildup or other debris catches fire inside the chimney. Conditions that encourage creosote buildup include burning unseasoned wood, restricted air supply (such as failing to open the damper), overloading the firebox, and cooler than normal chimney temperatures.
Why are chimneys so dangerous to firefighters?
The most common cause of chimney fires is the ignition of creosote in the flue. Regardless of how it occurs, the longer the smoke remains in the flue, the more likely it is that creosote will form and eventually catch fire inside the chimney flue, resulting in a chimney fire.
Can I burn off creosote?
Many homeowners allow their fire to smolder until it burns itself out. As the fire begins to burn out more creosote is produced at the lower temperatures. Rather than allowing the fire to smolder, it should be extinguished.
At what temp does creosote ignite?
451 degrees
At what temperature does a chimney fire start?
In the burning process, wood starts to chemically break down at 500oF, producing volatile gases including creosote. These gases burn at about 1100’F; if that temperature is not roached, the gases will escape up the chimney, resulting in the loss of much of the wood’s energy.
How do you know if you’ve got a chimney fire?
One of the most apparent signs of a chimney fire is visible flames, which are usually visible from the top of the chimney. It’s also possible that you will notice pieces of flaming creosote coming out of the chimney, even if you cannot see the flames directly. A loud cracking, popping or roaring noise.
