2-INSTALLATION INSTRUCT RULES FOR INSTALLATION The product is a boiler that uses wood pellets. Below is a list of European regulations regarding the installation of the product: EN 303-5:2012: Solid fuel boilers, with manual or automatic loading, nominal thermal power of 500 kW - Terminology, requisites, tests and marking. EN 12828 Heating systems design. Electrical systems with rated voltage not exceeding 1000 V AC and 1500 V DC.
2-INSTALLATION INSTRUCT The instructions in this chapter refer explicitly to the Italian installation regulation UNI 10683. In any case, always observe the domestic regulations in force. PELLETS Wood pellets are manufactured by hot-extruding compressed sawdust which is produced during the working of natural dried wood. The compactness of the material is guaranteed by the lignin contained in the wood itself and allows pellets to be produced without glue or binders.
2-INSTALLATION INSTRUCT PRECAUTIONS REGARDING INSTALLATION IMPORTANT! Product installation and assembly must be carried out by qualified personnel. The product must be installed in a suitable place that allows easy access for it to be opened regularly and for routine maintenance to be performed. The installation area must be: • suitable to enable the appliance to operate correctly. • Equipped with an adequate smoke extraction system. • Equipped with adequate ventilation from outside.
2-INSTALLATION INSTRUCT POSITIONING AND RESTRICTIONS In the case of simultaneous installation with other heating appliances, provide appropriate air inlets for each one (according to the instructions of each product).
2-INSTALLATION INSTRUCT FOREWORD This chapter on the Smoke Flue has been produced in reference to the prescriptions of European regulations (EN13384 - EN1443 - EN1856 - EN1457). The chapter provides indications for installing an efficient and correct smoke flue but is under no circumstances to substitute the regulations in force, which the qualified technician must be in possession of.
2-INSTALLATION INSTRUCT TECHNICAL CHARACTERISTICS Flues serving a pellet/wood fuelled appliance must meet the following requirements: • made of materials that are sufficiently resistant to mechanical stress, heat, the action of the products of combustion and their vapours.
2-INSTALLATION INSTRUCT ROOF AT 30° A = MIN. 1.30 metres B = DISTANCE > 1.50 metres C = DISTANCE < 1.50 metres D = 0.50 metres ABOVE HIGHEST POINT E = 0.80 metres F = REFLUX ZONE B C D A E 30° F FIGURE 4 ROOF AT 45° A = MIN. 2.00 metres B = DISTANCE > 1.30 metres C = DISTANCE < 1.30 metres D = 0.50 metres ABOVE HIGHEST POINT E = 1.50 metres F = REFLUX ZONE B C D A E 45° F FIGURE 5 ROOF AT 60° A = MIN. 2.60 metres B = DISTANCE > 1.20 metres C = DISTANCE < 1.20 metres D = 0.
2-INSTALLATION INSTRUCT DIMENSIONING The drop in pressure (draft) of a flue depends on its height. Check the drop in pressure with the values indicated in the technical characteristics. The minimum height of the chimney is 3.5 meters. The interior cross-section of the flue can be circular (best variation), square or rectangular (the ratio between the interior sides must be ≤1.5) with the sides joined with a minimum radius of 20 mm. The dimension of the cross-section must be a minimum Ø150mm.
2-INSTALLATION INSTRUCT MAINTENANCE The flue must be kept clean, since the deposit of soot or unburned oils reduces the cross-section reducing the draft and thus compromising the efficient functioning of the heater and, if large build-ups accumulate, can catch fire. The flue and chimney must be cleaned and checked by a qualified chimney sweep at least once a year. Once the maintenance has been performed, request a written declaration that the device is safe.
2-INSTALLATION INSTRUCT CONNECTION TO FLUE The connection between the flue and the appliance must be via a smoke duct that conforms with EN 1856-2. The connecting section must extend no more than 4 m horizontally, with a maximum incline of 3% and containing a maximum of 3 90% bends (accessible for inspection - do not count the T joint at the appliance outlet). The diameter of the smoke duct must be equal to or greater than that of the outlet of the appliance (Ø 100 mm).
2-INSTALLATION INSTRUCT EXAMPLES OF CORRECT INSTALLATION 1 U F E V I 1. Installation of Ø150mm flue with hole for the passage of the tube increased by: minimum 100 mm around the tube if next to non flammable parts such as cement, brick, etc.; or minimum 300 mm around the tube (or as prescribed by data tags) if next to flammable parts such as wood etc. In both cases, install suitable insulation between the flue and the ceiling.

4-INSTALLATION AND ASSEMBLY PREPARATION AND UNPACKING The COMPACT boiler is supplied complete with all its electrical and mechanical components and factory-tested: Open the package and remove the two screws between the bracket and the boiler and the two screws that fasten the bracket to the pallet. Set the boiler in the pre-selected place, making sure this complies with the requirements. The boiler body or unit must always be kept in a vertical position when handled and moved by using carts only.
4-INSTALLATION AND ASSEMBLY Therefore, the end user is responsible for product storage, disposal or possible recycling in compliance with the relative applicable laws. Position the product without its cladding and connect it to the chimney. Once the connections are complete, assemble the cladding (steel sides). If the product must be connected to an exhaust pipe that goes through the rear wall (to enter the chimney), make sure not to force it in.
4-INSTALLATION AND ASSEMBLY REQUIREMENTS FOR SYSTEM INSTALLATION 1235 660 400 • the minimum distance in front of the product to allow for cleaning, maintenance, etc.
5-PLUMBING CONNECTION PLUMBING CONNECTION IMPORTANT: The connections depend on the type of hydraulic kit installed and on the type of System Configuration. IMPORTANT! If installation of the product involves interaction with another, pre-existing system complete with heating equipment (gas boiler, methane boiler, diesel boiler, etc.), contact qualified personnel, who subsequently will be responsible for conformity of the system in compliance with the applicable law in force.
5-PLUMBING CONNECTION FILLING THE SYSTEM Fill the system slowly to allow air bubbles to pass through the vent holes of the heating system. For closed circuit heating systems, the filling pressure of the system at cold and the pre-inflation pressure of the expansion tank must be the same. • In open vessel heating systems, direct contact between circulating liquid and air is allowed. During the heating season, the user must check the circulating water level in the expansion tank regularly.
5-PLUMBING CONNECTION To fill the system, the hydraulic kit (optional) is fitted with a tap, with a check valve, to load the heating system manually. During this operation, any air in the system is released via the air valve located in the upper part of the boiler. To ensure the valve vents, it is advisable to loosen the side cap (see figure) The filling pressure of the system WHEN COLD must be 1 bar. Upon completion of this filling operation, always close the tap.
6-ELECTRICAL CONNECTIONS GENERAL PRECAUTIONS Electrical safety of the system is ensured only when it is properly connected to an efficient earthing system made in compliance with the safety standards in force: gas, water or heating systems pipes are not suitable as earth connections.
7-INITIAL START-UP BEFORE START-UP GENERAL PRECAUTIONS Remove all components that could burn from the brazier and glass (manual, various adhesive labels and any polystyrene). Check that the brazier is positioned correctly and rests properly on the base. After a long period of inactivity, remove any pellets left in the hopper (using a vacuum cleaner with a long pipe ), as they could have absorbed moisture, thereby altering their original characteristics and no longer being suitable for combustion.
7-INITIAL START-UP Do not stand close to the product and air the room. The smoke and smell of paint will disappear after about an hour of operation, however, remember they are not harmful in any case. The boiler will be subject to expansion and contraction during the start-up and cooling phases, therefore light creaking noises may be heard. This is absolutely normal as the structure is made of laminated steel and must not be considered a defect.
7-INITIAL START-UP LOADING THE PELLETS Pellets loading can be either manual or automatic. When empty the hopper can contain 100 litres i.e. roughly 70 kg of pellets. Manual Loading: • Open the upper door of the boiler directly and pour in the pellets. Automatic Loading (to be combined with the remote 100/200 or 400 kg hopper - optional - see accessories): • Remove the round plate from the door, cut the insulation and insert the hopper pipe. Subsequently load from the optional hopper.

It is designed to shut down the pellets feed screw in the event of an obstructed flue or significant back-pressure. (wind) SMOKE TEMPERATURE PROBE Detects the temperature of the smoke, thereby enabling start-up or stopping the product when the temperature drops below the preset value.
9-SAFETY DEVICES AND ALARMS TAMPERING WITH THE SAFETY DEVICES IS PROHIBITED If the product is NOT used as described in this instruction manual, the manufacturer declines all liability for any damage caused to persons and property.
9-SAFETY DEVICES AND ALARMS ALARM ALERTS Whenever an operating condition other than that designed for the regular operation of the boiler occurs, there is an alarm condition. The control panel gives information on the reason of the alarm in progress. A sound signal is not envisioned for alarms A01-A02 only so to not disturb the user in the event of pellets running out in the hopper during the night. Panel alert A01 A02 A03 Thermostat alarms A04 A05 Type of problem Solution The fire does not ignite.
9-SAFETY DEVICES AND ALARMS NORMAL SHUTDOWN (on the panel: OFF with flashing flame) If the shutdown key is pressed or if there is an alarm signal, the boiler goes into the thermal shutdown phase which entails the automatic execution of the following stages: • It stops pellets loading • The room fan (if provided) maintains the set speed until the smoke T reaches 100°C, then it automatically sets itself at the minimum speed until it reaches the shutdown temperature • The smoke fan sets itself at maximum spee
9-SAFETY DEVICES AND ALARMS Safety thermostat - Alarm A03 This type of alarm occurs when the water temperature in the boiler exceeds 95°C. The boilers contain a safety thermostat that prevents the water in the boiler from boiling. The safety thermostat in the boilers must be reset manually. This is done by pressing the small button between the two sockets (see below).
9-SAFETY DEVICES AND ALARMS DAILY OR WEEKLY CLEANING PERFORMED BY THE USER BEFORE EACH START-UP Using a suitable tool clean brazier “G” from ash and any incrustation which could obstruct the air passage holes. If the pellets in the hopper finish, unburned pellets may accumulate in the brazier. Always empty the residue in the brazier before starting-up. REMEMBER THAT ONLY A CORRECTLY POSITIONED AND CLEAN BRAZIER CAN GUARANTEE START-UP AND OPTIMAL OPERATION OF YOUR PELLET BOILER.
10-MAINTENANCE AND CLEANING CLEAN THE EXCHANGER AND THE UNDERGRATE SPACE EVERY 2/3 DAYS. Cleaning the exchanger and the undergrate space is a simple operation but very important for always maintaining performance as declared.
10-MAINTENANCE AND CLEANING PERIODIC CLEANING PERFORMED BY A QUALIFIED TECHNICIAN CLEANING THE EXCHANGER AND PIPE UNIT CLEANING THE UPPER COMPARTMENT When the boiler is cold lift front cover “H”, remove screws “O” to the right and left and remove cover “A”. Then remove the the fixing screws from drivers “V” and remove boiler cover “B”.
10-MAINTENANCE AND CLEANING Check the seal of the door gasket and replace it if necessary. At the end of the season one must clean the compartment under the brazier and the inside of the heat exchanger. This general cleaning should be carried out at the end of the season in order to facilitate the general removal of all combustion residues, without waiting too long, because with time and humidity these residues can become compacted.
10-MAINTENANCE AND CLEANING Ash collection tray A tray has been predisposed to collect the ash in the various boiler cleaning operations (from grate cleaning to ash pan emptying). The tray must be inserted between the front feet of the boiler; • tilt the tray as shown in the picture to facilitate insertion • lower it and make it slide until it rests against the boiler and is therefore fully closed. • When opening, the tray features a retainer at the end of stroke.
10-MAINTENANCE AND CLEANING END-OF-SEASON SHUTDOWN At the end of season, before shutting down the boiler, we recommend completely removing pellets from the hopper with the use of a vacuum cleaner with an extension. The service fuse may have to be replaced if the control panel display does not go on when the product is re-started upon pressing the main switch on the rear of the boiler. On the rear of the boiler there is a fuse compartment which is located underneath the supply socket.
