#4 installing into an existing chimney
This method provides excellent venting for normal
operation. This method also provides natural draft in
the event of a power failure. If the chimney condition
is questionable* you may want to install a liner as in
method #7.
In some places in the US and Canada it is required
that the vent pipe extend all the way to the top of the
chimney.
*The chimney should be inspected and cleaned before
installing your stove. If you discover that the chimney
does not have a clay tile liner or has cracks or flaking of
the tile liner you will need to install a stainless steel liner
within the chimney. In most cases the inside diameter
of this liner should be 4". Either flexible or rigid liner
may be used for this purpose. Refer to Method 6 & 7.
Be sure to design the venting so that it can be easily
cleaned.

The chimney should be sealed at the damper using a
steel plate. Kaowool, mineral wool or an equivalent non-
combustible insulation is recommended to be installed
on top of the sealing plate to reduce the possibility
of condensation. The connector pipe should extend
through the smoke chamber to the base or into the
first flue tile.
Be sure to design the venting so that it can be easily
cleaned.
