A chimney system consists of the connector off the top of the stove, and a chimney ,
which joins to the connector and terminates outside the building envelope.
A chimney can be a masonry chimney (of masonry construction with an inside liner), or
a factory built chimney.
A factory built chimney can be a double walled chimney (two concentric pipes with
insulation sometimes referred to as an insulated solid pack , or an air cooled chimney
(three concentric pipes, with insulation between the first and second pipes, and air
between the second and third pipes).
A single walled connector is a single pipe.
A double walled connector has two concentric pipes, no insulation, and is an air cooled
connector.
