Technical Description; Flue - Dal Zotto INSERTO 800 PRS Manuel Utilisateur

TECHNICAL DEsCRIPTION

The appliance is made up of a steel chamber completely soldered and hermetic. The hearth is coated by single cast-iron sheets and refractory
plates (NORDIKER).The appliances are equipped with an integrated air circuit for the recovery of the heat made up of a galvanized steel carter
external to the heating body. Inside the hearth there are a grate holder and the related grating, both made of very thick cast-iron and easily
extractable. The appliance works as an intermittent operating appliance.
The insert is equipped with a sight door with ceramic glass (resistant up to 700°C). This allows a charming sight on burning flames. Moreover,
in this way, any possible leak of sparks and smoke is avoided. Under the hearth grating there is a easily extractable ash drawer.

The heating of the room occurs:
a) by convection: the passage of air through the coating and the covering hood releases heat in the room.
b) by radiation: through the sight glass and the steel body, heat is radiated into the room.
The device is equipped with registers of primary and secondary air, with which it is possible to adjust the combustion air.
1A - PRIMARY air register
(Picture
With the air register located under the door of the hearth (on the left), it is possible to adjust the air flow through the ash drawer and the
grating in direction of the fuel. The primary air is necessary for the combustion process during the ignition. In order to open the passage of
primary air the lever should be completely pulled.
The ash drawer has to be emptied regularly, so that ash cannot hinder the intake of primary air for the combustion. Primary air is also
necessary to keep fire live.
During the combustion of wood, the primary air register must be opened only a few, since otherwise the wood burns quickly and the
device can overheat (see chapter NORMAL OPERATION).
2A - sECONDARY air register
Under the door of the hearth (on the right) there is the secondary air register.
This register must be opened (and therefore the lever completely pushed), in detail, for the combustion of wood, so that unburnt carbon
can be subject to a post-combustion, increasing the yield and assuring the cleaning of the glass (see chapter NORMAL OPERATION). It is
possible to get the air sECONDARY directly from outside through a flexible tube (fireproof NOT furnished
The adjustment of the registers necessary to reach the rated calorific yield is the following one:

FLUE

Essential requirements for a correct operation of the device:
• the internal section must be preferably circular;
• be thermally insulated and water-proof and produced with materials suitable to resist to heat, combustion products and
possible condensates;
• not be throttled and show a vertical arrangement with deviations not greater than 45°;
• if already used, it must be clean;
• all the sections of the flue gas duct must be accessible to inspection;
• inspection openings must be provided for cleaning.
• observe the technical data of the instructions manual;
Should the flues have a square or rectangular section, internal edges must be rounded with a radius not lower than 20 mm. For the rectangular
section, the maximum ratio between the sides must be = 1.5.
A too small section causes a decrease of the draught. It is suggested a minimum height of 4 m.
The following features are FORBIDDEN and therefore they endanger the good operation of the device: asbestos cement, galvanized steel,
rough and porous internal surfaces. In
For a correct installation please respect the sections/lengths of the flue shown in the technical data table. By installations
with different dimensions the flue must be suitably sized in accordance with EN13384-1.
The draught created by the flue must be sufficient, but not excessive.
A too big flue section can feature a too big volume to be heated and consequently cause difficulties in the operation of the device; to avoid
this, tube the flue along its whole height. A too small section causes a decrease of the draught.
ATTENTION: as far as concern the realisation of the flue connection and flammable materials please follow the requirements
provided by UNI 10683 standard. The flue must be properly spaced from any flammable materials or fuels through a proper
insulation or an air cavity.
It is FORBIDDEN to let plant piping or air feeding channels pass in the same flue. Moreover, it is forbidden to create movable or
fixed openings on the same for the connection of further other devices
