CentroPelet ZV14 TUZS-4-2014-ENG



Carefully read the precautions and follow the procedures correctly.

WARNING! Do not try to install the stove; always contact authorized and trained personnel. - In case of breakage or poor functioning always contact the Authorized Assistance Centre; any attempt to remove parts or perform maintenance on the device can expose the user to electrical shock danger. The stove contains parts whose maintenance must be done by the Authorized Assistance Centre. - The stove is a heating device; its parts reach extreme temperatures and contact without adequate protection can provoke burns of various degrees. Pay particular attention to children. - In case of a transfer, contact the Authorized Assistance Centre for the removal and new installation. - Do not insert fingers or other objects in the air flow exit slits. Inside the device there is a high speed fan that could cause grave personal injury. Pay particular attention to children. - Do not remain for long periods directly exposed to the flow of hot air. Direct and prolonged exposition to the cold air could be hazardous to health. Pay particular attention in rooms where there are children, the elderly or the ill. - In case the stove functions poorly, shut down the device immediately, unhook the appropriate automatic switch and contact the Authorized Assistance Centre. The continued use of the device in said conditions can cause fires or flashes.

WARNING! - During the stove installation operation, keep children out of the work area to avoid unforeseen accidents. - Do not block or cover in any way the body of the stove or obstruct the slits placed on the upper side. Obstructing said slits can cause fires. - Do not use the stove in areas containing precision devices or works of art. The quality of the conserved objects may deteriorate. - Do not expose animals or plants to direct air flow from the unit. Prolonged direct exposition to the flow of air from the stove can have negative effects on plants and animals. - Occasionally ventilate the room during the use of the device. Insufficient ventilation can be the origin of insufficient oxygen in the room. - Do not expose the stove to contact with water. The electrical insulation could be damaged, with the consequent possibilities of electrocution and breakage due to the thermal extremes. - Verify the installation conditions to locate eventual damage. - Do not use inflammable gas near the stove. - Unhook the automatic switch if the device will not be used for long periods of time. - We check the start up of all our stoves.

Installation • Every device must have its own flue with a diameter equal to or larger than the stove’s smoke clearing tube and a height not less than that declared. • Never use two stoves, a chimney and a stove, a stove and a wood kitchen, etc in the same environment, since the draught of one could damage the draught of the other. • Collective type ventilation ducts that can lower the atmospheric pressure in the installation environment are not permitted, even if installed in environments that are adjacent to and communicating with the locale of the installation. • It is forbidden to make fixed or mobile openings in the flue to connect devices different from that for which it is originally intended. • It is forbidden to pass other air feeding channels or tubes for electrical system usage through the flue, even if oversized. • It is advisable that the flue be furnished with a chamber which collects solid material and eventual condensation situated below the vertical entrance to the flue so that it is easily opened and inspected through the air-tight door. • Whenever flues with parallel exits are used it is advisable to raise the upwind chamber by one element. • The chimney tube must never pass across a combustible surface.

products of combustion is not inhibited by wind from any quarter or strength (windproof chimney cap). • The chimney cap must be positioned in such a way as to guarantee the adequate dispersion and dilution of the products of combustion and in any case, must be out of the reflux zone. This zone has different dimensions and forms according to the angle of inclination of the roof so it is necessary to adopt minimum heights (Pict. 2). • The chimney cap must be a wind-proof type and must be above the ridge. • Eventual structures or other obstacles that are higher than the chimney cap must not be too close to the chimney cap itself.

Sizing Smoke discharge The discharge system must be for the stove only (it is not permissible to discharge into flues in common with other devices). The smoke discharge takes place through the 8 cm diameter tube placed at the back. A “T” with a condensation collection cap should be provided. The smoke discharge of the stove must be connected with the outside using a steel or black tube (resistant up to 450°C) without obstructions. The tube must be hermetically sealed. To make the tubes airtight and for their eventual insulation, it is necessary to use material resistant up to at least 300°C (silicone or putty for high temperatures). The horizontal sections can be up to 2 m long. It is possible to have up to three 90° curves. If the discharge tube does not insert in the flue, an opportunely fastened vertical section of at least 1.5 m is necessary (except for evident safety contraindications) and a windproof termination (Pict.3). The vertical duct can be inside or outside. If the smoke duct is outside it must be insulated (Pict.4). If the smoke duct is inserted in a flue, this must be certified for solid combustibles and if it is larger than 150 mm in diameter, modification is necessary by inserting a tube and sealing the discharge with respect to the parts in brickwork. It must be possible to inspect all the sections of the smoke duct. If it is a fixed duct it must have openings for inspection and cleaning.

Sizing External air intake • The air flow can also be acquired from a locale adjacent to where the stove is installed as long as that flow can freely cross the permanent non-closable openings that communicate with the outside. • The presence in the local adjacent to where the stove is installed, of other devices in use or of suction devices that cause a contrary draught effect must not create a lower air pressure in the locale than in the outside environment. • In the adjacent locale the permanent openings must respond to the requisites which are listed in the points above.

The stove must be furnished with the air necessary to guarantee the regular functioning of the combustion and an environmental well being. • Be sure that the room where the stove is installed has sufficient aeration and, if necessary, install an air intake duct with a minimum recommended diameter of 50 mm to bring in air from the outside. • The external air intake must communicate with the stove and positioned so that it is not obstructed. It must be protected with a permanent non-closable grill or other suitable protection provided that the minimum diameter is not reduced.

Positioning • A grounded electrical connection is obligatory (if the cable issued with the stove is not long enough to reach the closet socket, use an extension cable along the floor).

The stove is furnished with an electrical cable to connect to a 230V 50Hz socket, preferably with a thermal-magnetic switch. Variations in tension of more than 10% can compromise the stove (if not already present, an adequate differential switch should be provided). The electrical system must comply with the norms; verify in particular the efficiency of the ground circuit. The electrical feed cable must be of a diameter adequate to the power of the device. The stove must be completely level. Verify the weight bearing capacity of the flooring. The placement of the stove within the living environment is determined so that the environment is heated in a uniform manner. Before deciding where to place the stove, keep in mind that: • The air used for combustion must not come from a garage or a space without ventilation or air exchange, but from a free space or the outside; • The stove should not be installed in a bedroom; • Rather it is preferable to install the stove in a large, central room of the house to insure the maximum heat circulation;

Fire Safety Distance The stove must be installed respecting the following safety conditions (pict.5): • Minimum distance from the sides and the back must be 20 cm from not inflammable material. • Minimum distance from the sides and the back must be 40 cm from moderately inflammable material; • Easily inflammable material must not be place closer than 80 cm in front of the stove; • If the stove is installed on an inflammable pavement the stove must be placed on a slab of material that insulates it from the heat that is wider at the sides by 20 cm and in the front by 40 cm; • Do not place objects in inflammable material or any material that can compromise the operation of the stove on the stove or within the safety distance; • In addition, it is advisable to keep all elements of combustible or inflammable material such as beams, wooden furniture, drapes, inflammable liquids, etc. outside the radiance area of the stove, and in any case at least 1 m from the heating block; • In case of connection to wooden walls or other inflammable material, it is necessary to insulate the smoke discharge tube with ceramic fibre or another material with the same characteristics.

Assembly and lighting of the stove, being sure not to place it on parts subject to heating. • Correctly connect the pellet stove to the flue, the air intake and to the water pipes. • Insert the plug into the socket and proceed with lighting following the phases described in the instruction manual. • Place the upper part and relative electrical connections from the command panel to the electronic board through the predisposed slits at the rear.

NOTE RELATIVE TO THE MAJOLICA (where present): the covering of the stove is realized in semi-refractory majolica (not to be confused, however, with other materials such as porcelain, for example). The quibbles and points or air holes are characteristic of this hand-made majolica, and therefore are not considered defects and do not influence even minimally the life of the product.

Please read carefully (and explain to the client) the warnings written in the use and maintenance manual before installing and starting up the stove!

Warning: handle with care

FRAGILE! 1. Before lighting by the authorized technician

Immediately after lighting the stove, verify setting of the technical parameters of the stove at the UT04 entry position on the display (see manual reserved for the personnel installing the stove).

ATTENTION: Be sure that the brazier basket is placed correctly. • Remove all the pieces from the container that were inserted during packing. • Unroll the environmental probe from the rear

2. ROOM THERMOSTAT (optional) The pcb has been arranged for an external thermostat on the connector CN7 and in particular on the clamps identified with the words "TERM". Please join the following procedure to check the room temperature using a thermostat: • switch off the pellet boiler stove using the master switch on the back • referring to the electrical wiring, remove the connection between the two clamps and connect the cables from the external thermostat. In this way, as soon as the set temperature is reached, you will read the words "ECO TERM" on the display

ATTENTION: During the first lighting it is necessary to ventilate the environment well, since during the first hours of operation unpleasant odours could develop due to fumes from the paint and the grease.

According to the setting of the room thermostat and the room temperature the stove has several operational modes. If, during the operation of the stove, the smoke temperature reaches 220°C (a parameter that can be modified by the technician) the smoke is modulated as follows: • smoke removal motor set at the maximum speed; • pellet loading gear motor at the minimum speed; This procedure functions to lower the temperature of the smoke. When this returns below the level of 220°C the stove will restore the speed of the three motors returning them to the settings before the level was passed. If the electrical current cuts out, once it is restored, the display will indicate a state of anomaly and will read COOL FIRE. The suction will be increased to expel the residual smoke.
