Question:
Venting the Smoke

torch.gif (2528 bytes)

Our wood stove is in the basement so we have about 30-40 feet of stainless steel 8" flue before it vents to the open air.
Often when I build a fire in the winter it's very difficult to get the fire & smoke to go up because of this cold column of air pushing down.

We get a lot of smoke in the room before it finally gets hot enough to ventilate. What can be done to solve this problem?

Thanks.    Don I.

Since you mention that the cold air is pushing down your flue, it sounds as if you have a situation of negative pressure. You may have an appliance operating when you go to start your fire that is drawing air out of the house (in competition with your fireplace) creating natural convection.

There are two things you may want to do. Instead of putting your wood into the fireplace right away, try to warm that column of cold air up in the flue first. Use a piece of lighted kindling or a couple of pieces of paper to warm up the flue. Secondly, you may want to try opening a window a little or consider adding an air intake outlet. While these suggestions may not completely solve your problem, they should help. For more information, visit Natural Resources Canada website at nrcan.com or email the provincial Department of Natural Resources and Energy at rthibideau@gov.nb.ca . As well, a WETT-certified wood stove dealer should be able to help you.
