There is no smoke without fire as the saying goes. In the case of a wood stove, it is better a fire, without smoke. Its appearance is sometimes linked to simple details. But it can also be a sign of a faulty installation.

First of all, when the ducts are cold, at the beginning of the winter season, for example, it is normal that it emerges a little smoke. This must disappear as the stove heats up. Similarly, a fire that is not powered enough produces smoke. In this case, it is sufficient to add fuel to revive the flame. Logs or pellets, make sure they are dry.

If you have a VMC (Mechanical Controlled Ventilation), it is possible that it interferes and produces an inverted draw that causes smoke. To check, simply cut it, at least, when turning on the stove. A lack of ventilation of your home can also be involved. Try to let the air through as much as possible. If you have identified the problem, call a specialist who will guide you to additional ventilation solutions.

Also examine the fireplace of your woodstove, its ducts and those of the chimney. They must not be dirty. And make sure that the ventilation valve of the combustion chamber is open.

The smoke that instead of going up, in the ducts goes down in your interior can also be due to a problem of drawing. In this case, remember to have the ducts checked which may be too bent or simply plugged. Justan excess of soot or the presence of a bird's nest to obstruct. A sweeping will solve the problem quickly. If the chimney flue is not straight enough to allow smoke to escape easily, casing should be done. That is, the introduction of a flexible metal sheath that will replace the existing duct.

The exit on the roof, may be non-compliant, for example too exposed to the wind. The problem can also find its source in the home, if it is too big or too small compared to the size of the duct.

In all these cases, it is advisable to call in a professional who will establish an accurate diagnosis. The solutions are numerous and not necessarily expensive. Sometimes, it is enough to add a smoke aspirate to the top of the chimney.

Also think about contact the manufacturer. If your stove is new, it may be a technical detail that escapes you or more rarely a manufacturing defect.
