#6 installing into an existing fireplace
chimney
This method provides excellent venting for normal
operation. This method also provides natural draft in
the event of a power failure.
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 pipe or liner inside the chimney should
be 4" diameter.
In this method a cap should also be installed on the
chimney to keep out rain. Be sure to use approved
pellet vent pipe fittings. Seal pipe joints with silicone or
aluminum tape in addition to the sealing system used
by the manufacturer. Pipe size should be increased to
4" using this method.
