#6 Installing into an existing fireplace
This method provides excellent venting for normal
operation. This method also provides natural draft in
the event of a power failure.
Some places in the US and Canada, it is required
that the vent pipe extend all the way to the top of the
chimney.
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 in
addition to the sealing method used by the manufacturer.
Pipe size should be increased to 4" using this method.
