SUMMER STOPAfter you have cleaned the hearth, the chimney and the flue, trying to eliminate completely the ash andothers residuals, close the doors of the hearth and its registers; in case you disconnect the appliance fromthe chimney you must close its openings in order to let work others possible appliances connected to thesame flue.The cleaning of the flue should be done at least once a year; in the meanwhile check the state of thegaskets, which if not perfectly intact, that is to say that they are not more close-fitting with the stove, do notguarantee 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 absorbentsalts 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 castiron with neutral Vaseline.17.

In theconnection, 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 clampwith which the thermoproduct is equipped;• each metre of the horizontal stretch of the flue gas channel causes a slight loss of head which mustbe 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 ifnecessary by elevating it suitably;• The UNI 10683-2005 – ITALY regulation requires that under no circumstances must there be morethan 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 theentrance 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 tubewith a diameter of at least 200mm, pos.B, taking care to close the remaining spaces between the pipe itselfand the flue immediately under the chimney pot pos.
