#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.
