MASONRY CHIMNEY:
You can also install your stove using your existing masonry chimney. To do so, follow the
guidelines below. You may want to use a factory-built thimble, or construct your own brick
thimble. If you are using a masonry chimney, it is important that it be built in compliance with the
specifications of the Building Code in your region. It must normally be lined with fire clay bricks,
metal or clay tiles sealed together with fire cement. (Round flues are the most efficient).
