13 Safety elements, fuel.. SAFETY ELEMETS Boiler have a few safety elements: - Bimetal thermostat built on the burner pellet feeding tube. If the bimetal set temperature (0 C) is exceeded, pellet feeding is stopped, the burner shuts down and the error E appears on the control unit (LED diode switches on). - If there is no flame (the built in photo-cell does not detect the flame within set time), control stops the burner operation and error E is displayed or it goes to blowing off and error E is - Displayed (LED diode switched on).control unit has a built in protective function which protects the boiler against overheating. If temperature in the boiler exceeds 9 C, regardless heating or sanitary water is needed the boiler pump and/or the sanitary water turns on and works until temperature in the boiler falls below 9 C. - The fan has a built-in RPM counter and, if regulation is informed that the fan does not operate in accordance with the requirement interrupts the process display fan error - Drive for grate linear move have in-built two switches by wich control unit monitor position of grate. If grate at given moment is not on provided place, control unit recieve information that grate is not on provided place and interrupt proces and display information about grate error. - Flue gas connection have in-built sensor for flue gas temperature meassuring. If flue gas tube temperature is over 0 C, control unit interrupt proces and display information about too high flue gas temperature. When temperature in the boiler exceeds 0 C (+0 C / - 9 C), power supply is turned off by the safety thermostat (via control unit). Thermal protection built in coils of the fan electric motor at the burner and the screw feeder motor, protects them against overheating caused by failure or locking. A flexible tube connecting the pellet burner and pellet tank is made of plastic material reinforced with metal wire which, in case of back flame from the burner to the tank, melts and prevents flame to penetrate to the pellet tank... FUEL Wood pellets are used as fuel in boilers with built-in pellet burner. Wooden pellets are bio-fuel made of wooden wastes. Pellets can be packed in different packaging: in bags ( kg or 000 kg), or as bulk in large (underground) tanks ( - m ) or in basement spaces. Recommended properties of pellets for firing in PelTec boilers are the following: - heating value >= kwh/kg ( MJ/kg) -diameter <= mm -max. moisture content <= % -max. dust content <=, %.

14 .0. BOILER POSITIOIG AD ASSEMBLY Boiler positioning, assembly and building in must be performed by a qualified person. We recommend that boiler is placed on a concrete base with height of 0 to 00 mm above the floor. Boiler room must be frostproof and well ventilated. Boiler has to be positioned so that it can be properly connected to the chimney (see Figure ) and simultaneously, enabling tending of boiler and additional equipment, control during operation, cleaning and maintenance. WARIG! Flammable items must not be placed on the boiler and within the minimum distances shown in Figure... MIIMUM DISTACE FROM THE ROOM WALLS Figure. Minimum distance from the room walls for PelTec min. 00 mm max 00 mm min. 0 mm min. 0 mm min. 00 mm - Boiler PelTec - Chimney - Flue (Chimney connection; must be insulated).. OPEIG FOR FRESH AIR (FRESH AIR SUPPLY) Each boiler room must be equipped with an opening for supply of fresh air which is dimensioned in accordance with boiler output (minimum opening area according to the below shown equation). Such opening must be protected with a net or grate. All installation works have to be performed in accordance with valid national and European standards. Boiler must not operate in flammable and explosive environment. A =,0 x Q A - opening area in cm Q - boiler output in kw

15 Connection to the chimney.0. COECTIO TO THE CHIMEY IProperly dimensioned and built chimney is the main condition for safe and economical functioning of the boiler. The thermal insulation of the chimney has to be done properly, it has to be absolutely gas-proof and smooth. On its lower part there has to be built in the opening for cleaning with the door. An brick-layed chimney has to have three layers with an insulation of 0 mm in the middle, if the chimney is built inside the house (i.e. inside the heated area), or an insulation of 0 mm if it is built outside the house (i.e. outside the heated area). The flue gas temperature has to be at least 0 C higher then the temprerature of their consdensation point. The choice and the construction of the chimney has to be performed by the authorized person. Inside dimensions of the chimney intersection selected in accordance with diagram for chimney selection, they depend of its height and of the capacity of the boiler. Chimney must be dimenensioned by "diagram for chimney selection" and maximum permetted lenght of connection flue gas tube between connection on fan and chimney is 000 mm and minimum light diameter xx0 mm with maximum two 90 bends. Connection flue gas tube can be mounted horizontally or at any angle which allows to gas, on his way to chimney, a constant increase of height with condidering of exit point from fan. Connection flue gas tube must have openings for cleaning through which is possible to clean entire lenght of flue gas tube or must ensure easy removal part of flue gas tube which allow complete cleaning of connection flue gas tube. To prevent entry of condensate form chimney into the boiler, flue gas tube must be mounted 0 mm deeper into the chimney. Connection ue gas tube between fan and chimney must be insulated with 0-0 mm mineral wool. The chimney must be resistant against flue condensate! Figure.
