#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.
