This method also provides natural draft in the event of a
power failure.
In Canada and some places in the US 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
system used by the manufacturer. Pipe size should be
increased to 4" using this method.
