Capital Sirius 490MF Installation And Operating Instructions Manual page 6

Installation
Once the installation is complete, the installer must advise the householder on
the correct use of the stove and warn them to use only the recommended fuels
listed in this document. The installer must also advise the householder on the
actions to be taken should smoke or fumes be emitted from the stove.
Your Sirius stove must not share a chimney with any other appliance
Where the chimney is believed to have previously served an open fire
installation it is possible that the higher flue gas temperature from a closed
appliance may loosen deposits that were previously firmly adhered, with the
consequent risk of flue blockage. It is therefore recommended that the chimney
be swept a second time within a month of regular use after installation.
Check the chimney is in good condition, dry, free from cracks, leaks and
obstructions. The diameter of the flue should not be less than 150mm and not
more that 230mm. If any of these requirements are not met, the chimney
should be lined by a suitable method.
In the case of the Sirius 490 stoves burning as clean burn appliances (clean burn
kit fitted), a 125mm flue liner may be used in accordance with the Building
Regulations. All other stoves must have a minimum 150mm diameter liner. The
chimney and connecting flue pipe should not narrow to less than the size of the
outlet socket (collar) of the stove at any point.
The chimney height and the position of the chimney terminal must conform to
Building Regulations and the latest edition of BS EN 15287‐1:2007, Design,
Installation and Commissioning of Chimneys should be followed.
A flue draught of minimum 12 Pascals is required for satisfactory appliance
performance. The flue draught should be checked under fire at high output and
if it exceeds 25Pa, a draught stabiliser may be required so that the rate of
burning can be controlled, and to prevent possible over‐firing.
If you have any doubts about the suitability of your chimney, consult your local
dealer/stockist. He will also be able to provide advice about the possible need
for a specialist cowl.
