Venting
#5 Installing into an existing fireplace chimney (US
and canada)
This method can be done with or without a flue liner. Without
a liner, the damper area must be sealed off with a steel plate.
Kaowool, mineral wool or an equivalent non-combustible
insulation is recommended on top of the steel plate to
minimize condensation. In this method a cap should also be
installed on the chimney to keep out rain.
Some places in the US and Canada require that the vent pipe
extend all the way to the top of the chimney. Per ULC S628.
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.

#6 Installing into an existing chimney (US and Canada)
This method provides excellent venting for normal operation.
This method also provides natural draft in the event of a
power failure.
In this method a 4 inch liner is installed the entire length of
the flue. Whether using a rigid or flexible liner, a cap should
be installed on the chimney to keep out rain.
