The two most important things required to maintain a smoke free masonry chimney or fireplace are supplying the fireplace with adequate amounts of air and the sizing of the fireplace.
There are new advanced factory-built fireplaces with offer advanced combustion systems, tight-fitting ceramic glass doors and heat exchangers.
These new types of fireplace are designed to be installed inside the firebox of your existing masonry fireplace allow it to be converted into a more efficient heating system.
Also a stainless steel chimney liner is installed inside the existing masonry chimney with the vent inserts extending to the outside of the house which improved the performance and safety of your fireplace.
Another way to be sure that you have a smoke free masonry chimney is to install an exhaust fireplace fan, also called Chimney smoke fan and Exhaust chimney fans among other things.
These fans are supposed to be one hundred percent effective solution for chimney smoke problems, improperly sized flues, poor design etc. Some of the advantages of these exhaust fireplace fans are:
. One hundred percent guarantee that there will be no fireplace smoke in the house. 100% smoke free.
. They use as much energy as a regular light bulb and operate very quietly
. They are maintenance free motor. They come an a variety of colors to math any exterior
. Acts as a ventilator to clear the house of other odors (smoke, cigarette etc). If your firebox opening is too big you will have to reduce the opening in order to have a better drafting system.
You should hire a professional who is better equipped to handle this type of project. Another option would be to supply the fireplace with its own air supply.
This would entail building a duct from one of your basement windows moving along the ceiling of the basement and continuing up through the floor that is in front of or to the side of the hearth with the floor of the fireplace extending outside of the firebox.
Next you will have to place a grille over the opening and install a lid so that you will be able to close the duct when the fireplace is not in use.
Again if you are not sure that you can handle the job, you can hire a professional to do the job for you.
