Smoke flue
Connection to the smoke flue
Ensure the flue’s dimensions meet
local regulations and the applicable
installation standards in line with good
practice.
Basic information
For good draught, the stove must be
suited to the flue (or vice versa).
An oversized flue is as detrimental to
the smooth operation of the stove as
an undersized flue.
You will find a simplified method
providing an initial evaluation of the
characteristics of the flue based on the
type of stove at Su www.stuv.com >
Info e Servizi > Questioni pratiche
As the Stûv 30-compact is a highly
efficient stove, the smoke flue must
be of good quality. The flue must also
be as straight and smooth as possible
and insulated to encourage drawing
and to prevent condensation.
The ideal solution is a flue built inside
the building and thermally insulated.
An outside flue without any insulation
must be avoided.
The stove must never be connected to
a smoke flue serving several systems.
Take care to avoid heat loss !
If several flues are available : only use
one of them. Block up the unused
flues at the top and bottom and,
generally speaking, ensure that the
top of the recess where the stove is
fitted is air-tight.
Standard outlet diameter
The Stûv 30-compact stoves have an
outlet of Ø150mm.
Some flue configurations may
require a different diameter than that
provided as standard. Should this be
the case, please consult your retailer.
Allow play of 2mm/m for expansion
of the flue and to ensure smooth
rotation of the stove.
Connection above
[diagrams 1/a and 2/a]
If the flue is straight, it is simply
placed on the stove ; the flue turns
with the stove.
If the flue has an elbow or is
deflected, it is fixed at wall or ceiling
level (rotation of stove only).
Air-tightness
The various components which make
up the connection between the stove
and the smoke flue and those which
make up the flue itself have to be
fitted so that they are airtight for the
condensation [diagram 2/a] rather
than the smoke [diagram 2/b].
Calculation of the height of the
duct
For the sinking of the duct at stove level,
add 25 mm for a duct 2 mm in thickness
and 35 mm for a 0.4 mm
duct.
