1.2 The chimney / flue system
Note that the flue system must be independently secured and must not rely on the stove for support.
DO NOT CONNECT THIS UNIT TO A CHIMNEY FLUE SERVING ANOTHER APPLIANCE
Use a residential type masonry or listed type HT factory-built chimney.
High Temperature (H.T.) Chimney Standard UL-103-1985 (2100º F.) or a code-approved
masonry chimney with flue liner for the USA, and High Temperature (650ºC) Standard
ULC S-629 for Canada.
The internal dimensions of the chimney connector and chimney must not be less than 6 inches
diameter (or equivalent cross section), and should not be significantly larger than this. Too large a
section will tend to allow the flue gases to cool excessively, causing sluggishness or unpredictability
in the stove’s performance.
We recommend the length of the chimney system should be at least 16 feet (not required) above
the stove in normal domestic situations, measured from the flue collar to the top of the chimney.
Local conditions like for example - roof constructions, large trees nearby and high altitude, may
influence the chimney draft and height. Therefore, contact the local professional chimney sweep
or your Morsø dealer.
