LUE OUTLET POSITION
The flue outlet angle and position is
determined by the orientation of the flue
collar. The outlet can be either vertical or
leant backwards by 30°. To change the angle,
rotate the flue collar by 180°. The effective
centre dimensions in millimeters are shown
below.

EQUIREMENTS
The flue serving this appliance must be dry,
free from cracks and obstructions and be in
accordance with the designations shown in
Table 1.
The diameter of the flue should not be less
than 150mm and not more than 200mm. If
these requirements are not met the chimney
should be lined by a suitable method.
If there is no existing chimney then either a
prefabricated block chimney in accordance
with Building Regulations Approved
Document J or a twin-walled insulated
stainless steel flue to BS EN 1856 can be used.
These chimneys must be fitted in accordance
with the manufacturer’s instructions and
Building Regulations.

The chimney/flue should have a vertical
height of at least 4.5 metres and should
terminate in accordance with Table 2.
If the chimney is believed to have previously
served an open fire installation, it is possible
that the higher flue gas temperature from the
stove may loosen deposits that were
previously firmly adhered, with the
consequent risk of flue blockage. It is
therefore recommended that the chimney is
swept a second time within a month of
regular use after installation.
If you have any doubts about the suitability
of your chimney, consult your local
dealer/stockist.
Both the chimney and flue pipe must be
accessible for cleaning and if ANY part of the
chimney cannot be reached through the
stove (with baffle removed), a soot door
must be fitted in a suitable position.
