INTERIOR SUPPORT
A liner installed in a fireplace chimney will require an
interior support at the top of the fireplace.

• Install the support plate on top of the fireplace
• Proceed with the erection of the liner along the
chimney construction as described before.
• EXISTING FIREPLACE (fig.9)

• (see "existing chimney lining"). With the liner
hanging in the fireplace, place the interior support in
position and mark its location on the liner.
• Remove the support and attach the support collar
around the liner slightly above your mark.
• Attach the support to the fireplace wall using four
bolts and lags.
• Continue connection to your stove.
