1.3 The chimney / ue system
Note that the ue system must be independently secured and must not rely on the stove
for support.
The stove must not be connected to a chimney ue serving any other appliance. (Sev-
eral ues may run up a single chimney stack; use one ueway per 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 ue 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 inch-
es diameter (or equivalent cross section), and should not be signicantly larger than this. Too
large a section will tend to allow the ue 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 ue collar to the top of
the chimney.
Local conditions like for example - roof constructions, large trees nearby and high altitude,
may inuence the chimney draft and height. Therefore, contact the local professional chim-
ney sweep or your Morsø dealer.
