Kalor Ermetica 98 Cast Round 10C Bedienungsanleitung Seite 28

The stove, thanks to a structure perfectly sealed,
does not consume the oxygen in the external
environment and can therefore be placed in the
inside of all homes well insulated and within the
passive ones.
To meet these requirements the connecting tube,
50 mm diameter, for the combustion air inlet must
be connected to the outside of the building.
In addition, the air intake must:
• be protected by a grille, metal mesh or a suitable
protection as long as they do not reduce the
minimum section.
• positioned to prevent it from being blocked.
• the maximum length permitted for ducting is 2
meters with two 90 ° bends.
Connection to the flue pipe
The flue pipe must have internal dimensions not
larger than 20x20 cm, or diameter 20 cm. In the
event of larger dimensions, or of the flue pipe
being in poor condition ( for example cracks, poor
insulation, etc.), it is advisable to fit a stainless
steel pipe of suitable diameter inside the flue pipe
throughout its length, right up to the top. Check
with suitable instruments that the draught is as
shown in the table. This type of connection ensures
the evacuation of the fumes even in the event of
a temporary power cut. At the bottom of the flue
pipe, provide an inspection cap to allow periodic
checking and cleaning, which must be done
annually. Make a gas-tight connection to the flue
pipe, using pipes and connectors as recommended
by us. You must ensure that a windproof cowl
should be fitted which complies with the standards
in force (Fig. 1) .
Connection to an external flue with insulated
or double-wall pipe
The only type of pipe which is permissible is
insulated (double-walled) stainless steel, smooth
on the inside, fixed to the wall. Flexible stainless
steel pipe must not be used. At the bottom of
the flue pipe, provide an inspection cap to allow
periodic checking and cleaning, which must be
done annually. Make a gas-tight connection to
the flue pipe, using pipes and connectors as
recommended by us. You must ensure that a
windproof cowl should be fitted which complies
with the standards in force. Check with suitable
instruments that the draught is as shown in the table
(see page 11) .
Connection to the flue pipe

For proper functioning, the connecting pipe
between the stove and the chimney or flue duct
must have a slope of not less than 3% in the
horizontal stretches, the length of which must not
exceed 2 metres and the vertical distance between
one tee connector and another (change of
direction) must not be less than 1,5 m. Check with
suitable instruments that the draught is as shown in
the table. At the botton of the flue pipe, provide
an inspection cap to allow periodic checking and
cleaning, which must be done annually. Make a
gas-tight connection to the flue pipe, using pipes
and connectors as recommended by us. You must
ensure that a windproof cowl should be fitted
which complies with the standards in force.
The hermetic stove works best with a connecting
pipe PGI 80/130 with vertical configuration (7,95
m) and horizontal (2,8 m).
