Between the stove and chimney, use thick-walled smoke piping (Steel, ≥2 mm). See
Chapter 2.2.
The fi rst pipe connected to the appliance must have a diameter of 130 mm at both ends.
This will prevent any condensation from the chimney running over the external end
of the pipe. Connect the pipes to the existing chimney (ceiling) using a sliding sleeve
(niche pipe). Check all connections for air-tightness.
If there is too much draught running through your chimney (e.g. if the chimney is long
and straight in a tall building), it may be possible to insert a chimney valve in the pipe
near the appliance. Before doing this, be sure to obtain sound advice from a specialist.
Do not make any horizontal connections. Deposits and soot will accumulate here
(unless it is a short horizontal connection directly behind the stove).
Avoid bends at all costs. The maximum deviation from the perpendicular is 45°.
The chimney calculation, as in Germany, is made according to DIN 4705 parts 1 and 2.
The mass fl ow and exhaust temperature of the stove
The mass fl ow and exhaust temperature of the stove are shown in chapter 8;
Technical Data. These values are important to consider when assessing the dimensions
of the fl ue to which the stove is to be connected.
Cleaning the chimney/fl ue
Make sure your chimney/fl ue is cleaned at least once a year by a recognized chimney
sweep.
If the chimney has a chimney valve, the free opening in the chimney valve fl ap must
measure at least 12% of the surface.
3.3 COMBUSTION AIR
Combustion air is needed to keep the combustion going by drawing in air from the
room, of directly from outside, due to the natural draught of the chimney.
On delivery, the appliance is prepared for a combustion air supply from the living room
or a combustion air supply directly from the outside, through the underside or through
the back of the appliance.
• Combustion air from the living-room:
The air inlet openings are located under the operating fl ap. When using the
appliance, please ensure there is a suffi cient supply of fresh air: use a grate with a
minimum net opening in the outer wall of 150 cm
Make sure that the ventilation supply is open; this is particularly important with
today's airtight dwellings.
