7 - FUEL There are numerous types and qualities of wooden pellets on the market, so it is important to choose one that contains no glue, resins or chemicals and may cause early clogging of the smoke discharge, the formation of corrosive gases, loss of efficiency and the emission of polluting substances into the atmosphere.
8 - INSTALLATION PREINSTALLATION Before installing the stove, check that everything has been prepared. Find below a quick checklist, for the complete information always refer to the pre-installation card. Check that: the surface supporting the stove is level and cannot be affected by the heat;...
FLUE PIPE For the stove to work well, the flue must be made by a qualified engineer that must comply with the regulations in force (UNI EN 10683). If that is not the case, the company cannot be held responsible for any malfunctions. To clarify things: chimney or flue is the vertical part of a duct that is characterized by its own draft (natural convection).
Page 25
In particular, as to flues/smoke ducts, we wish to remind you of the following: MATERIALS: They must withstand mechanical stress. They must withstand any acid condensation that may form from the combustion products (the use of STAINLESS STEEL 316 is recommended). They must be waterproof.
Page 26
It must prevent rain, snow and foreign bodies from getting in. It must not be close to other buildings, but have a free outlet that ensures combustion gases are dispersed into the atmosphere and above all, if the outlet is on a roof, its height must exceed the reflux area. Inox Isolante Inox...
Page 27
In pellet boilers, smoke extraction is guaranteed by a fan keeping the combustion chamber pressurized, com- bined with a state-of-the-art chimney that must allow smoke evacuation using the natural draught. For this reason we recommend you contact a specialized engineer to build the flue. The costs for any modification in programming carried out by the service centres, due to the incorrect installation of the flue, will be debited to the user.
ELECTRICAL ARRANGEMENT All the units are fitted with an electrical supply cable: if this has to be replaced (e.g. if damaged), contact an authorized Technical Service Centre. Before connecting the unit, make sure that: the electrical system is fitted with a 6A thermo-magnetic circuit breaker the system characteristics meet the details on the data plate applied to the unit (electrical power, rated voltage, etc.) the system is fitted with an efficient ground connection, in compliance with the legal regulations in force (ground- ing is compulsory by law)
Page 29
If hot water must be produced, a water heater must be installed, holding at least 80 litres, so that the stove can work efficiently. The stove is fitted with an 8-litre expansion tank: if this is insufficient for the system, one of suitable size must be installed.
UNPACKING We recommend you unpack the equipment only after transporting it to the place where it must be installed and only at the time of installation. This operation must be done using all the possible personal protection equipment used to protect people (gloves, safety shoes, etc.).
SETTING UP THE STOVE After unpacking the stove, position it in the room where it will be used. You can use a forklift truck or transpallet. In moving the stove, pay attention not to damage its external parts. Please pay attention to the distances men- tioned above.
CONNECTING THE FLUE The stove can be connected to the previously installed flue pipe in two ways. The first one is vertically, that is having the pipe come out of the top part of the stove; the second one is horizontally, coming out from the back of it.
Page 33
HORIZONTAL CONNECTION Carry out the following operations as shown in the pictures on the side: Close the “T” fitting with the ash collection cap (1) and connect it to the smoke motor (2), not for the Thema H model. Install a 90° bend (3) to get the fume discharge on the back. Connect a straight pipe to the bend and to the flue (4).
COMBUSTION AIR INLET Combustion air can be taken from the room, if sufficiently ventilated, or from the outside, if not: this way optimal com- bustion is guaranteed, avoiding opening an air intake in the room. In both cases, refer to the regulations about installa- tion in force (UNI 10683 and UNI7129), to avoid health risks for those who spend time in the room where the equipment is installed.
HYDRAULIC CONNECTIONS Vent the heating system and the stove every time you fill it. Connect and take outside the stove the discharge of the safety valve. On the return circuit, a chemical-physical water treatment system must be installed, for instance a magnetic dirt separator: it is necessary to protect the stove internal components, such as the elec- tronic circulator, from impurities and ferrous particles present in the system.

ALARM CODE LIST For your safety, do not tamper with or modify any component of the equipment: the manufacturer does not guarantee its correct operation, which can be very dangerous. In case of malfunction, problems or if a safety device is triggered, please call authorized personnel. Anyway, all operations must be carried out with the burner off and cooled down and with the power disconnected.
10 - CLEANING During maintenance, use personal protection equipment all the time (i.e. gloves). For the stove to work perfectly, we recommend it undergoes thorough cleaning at least once a week when using wood pellets. If biomass is used (olive pits, shells, agripellets), cleaning must be carried out between 1 and 3 days according to the quantity of residue left in the burner.
10.2 CLEANING THE BURNER Before starting any operation on the burner, wait for it to fully cool down (about 3 hours). Clean the burner every 1 to 7 days according to the type of fuel used. Before starting work on the burner, disconnect the stove from the mains and turn the circuit breaker on the main panel to OFF.
Unburnt residue inside the crucible (7), can be aspirated but can also be made to fall on the bottom with a scraper (8), where it will then go into the ash collection drawer. Once cleaning is complete, the burner lid can be refitted and closed, carrying out the same operations in reverse order.
Check and lubricate the bushings of the fuel loading auger and of the burner. Check the magnesium anode of the water heater For any other operation not mentioned in this list, please refer only to the CS THERMOS service centre.
