The stove cannot be used to support the chimney/flue pipe.
If an existing flue pipe/chimney is used, it must be cleaned by an author-
ised chimney cleaning company before installing the stove. The presence of
soot and combustion residue can reduce the flow up an existing flue pipe/
chimney and cause the stove to malfunction. The accumulation of soot and
other foreign bodies can trigger hazardous situations. If an existing flue
pipe/chimney has a diameter in excess of 150 mm, it must be adapted to suit
a pellet stove by fitting a pipe inside the existing chimney.
Please note: Have the existing chimney checked by an authorised
chimney maintenance company in order to verify its suitability for the
combustion of solid fuel such as pellets.
The chimney draught must be 11Pa (plus or minus 1 Pa). This draught should
be measured when the chimney is hot. Poor draught can lead to dangerous
situations because the flue gases can spread into the room.
Never place a flue gas fan inside or above the flue gas/chimney channel. The
stove is already equipped with a cat back exhaust fan. An additional fan
inside or above the channel may impede proper functioning of the stove.
A chimney or a part of it fitted outside the house must have a double wall.
See Figure 8. A single-wall pipe can be used inside the house.
