Summer Stop; Connecting A Fireplace Or Open Hearth To The Flue - Nordica STELLA Instructions Pour L'installation, L'utilisation Et L'entretien

16. SUMMER STOP

After you have cleaned the hearth, the chimney and the flue, trying to eliminate completely the ash and
others residuals, close the doors of the hearth and its registers; in case you disconnect the appliance from
the chimney you must close its openings in order to let work others possible appliances connected to the
same flue.
The cleaning of the flue should be done at least once a year; in the meanwhile check the state of the
gaskets, which if not perfectly intact, that is to say that they are not more close-fitting with the stove, do not
guarantee the good working of the stove! In that case the gaskets must be replaced.
In presence of dampness in the room where the stove has been placed, we advise you to put absorbent
salts into the hearth.
If you want to keep for long the aesthetic look of the stove it is important to protect its internal walls in cast
iron with neutral Vaseline.

17. CONNECTING A FIREPLACE OR OPEN HEARTH TO THE FLUE

The flue gas channel is the stretch of piping which connects the thermoproduct to the flue. In the
connection, these simple but extremely important principles must be respected:
•
under no circumstances use a flue gas channel with a diameter less that that of the exhaust clamp
with which the thermoproduct is equipped;
•
each metre of the horizontal stretch of the flue gas channel causes a slight loss of head which must
be compensated if necessary by elevating the flue;
•
the horizontal stretch must never exceed 2 m (UNI 10683-2005);
•
each bend of the flue gas channel slightly reduces the flue draught which must be compensated if
necessary by elevating it suitably;
•
The UNI 10683-2005 – ITALY regulation requires that under no circumstances must there be more
than 2 bends or variations in direction including the intake into the flue.
If the user wishes to use the flue as a fireplace or open hearth, it is necessary to seal the hood below the
entrance point of the flue gas channel pos. A Picture 9.
If the flue is then too big (e.g. 30x40cm or 40x50cm), it is necessary to intubate it with a stainless steel tube
with a diameter of at least 200mm, pos. B , taking care to close the remaining spaces between the pipe itself
and the flue immediately under the chimney pot pos. C .
