- Page 2 Flue The flue represents one of the fundamental elements of the heat generator. The correct designing of the fumes evacuation system guarantees the correct and always efficient generator functioning and prevents the potentially dangerous situations for the user. For a correct installation, refer to section 6.5 pag.17 of this manual and, however, use experienced staff.
- Page 3 Electrical connections The generator is equipped with a main switch not automatic ISOLATOR type. It is recommended to protect the power supply line using a differential magne- tothermic switch. Refer to the attached control board manual for electrical connections.

3. FUNCTIONING, TECHNICAL FEATURES AND DIMENSIONS 3.1 Generator operation illustration The generator is a three flue passes type for the production of hot water for residential and indu- strial heating. 3.2 Generator operation description The fuel descends by gravity from the hopper into the upper feeding screw, where it is pusher into the star valve (optional) falling then into the burner feeding screw. -

6. INSTALLATION AND TESTING 6.1 General installation requirements The electrical and thermo-hydraulic installation of the heat generator and any other assistance or maintenance operation must be carried out by personnel registered in the professional register established at the Chamber of Commerce, in compliance with Ministerial Decree 37/08. The thermo-hydraulicand electrical installers must release a Cartification of Conformity in com- pliance with Ministerial Decree 37/08 and implementation regulation. -
Page 17: Flue And Draught
6.5 Flue and draught The flue is one of the most important elements for a correct generator operation. In general a good draught is obtained when flue is thermally insulated, designed with a double wall and insulated to prevent the fumes from cooling, thus maintaining the pressure difference that allows the fumes to go up the flue to the external outlet. -
Page 18: Electrical System And Connections
fig. 6.5.3 6.6 Electric plan and connections The generator is equipped with a non-automatic main switch. We recommend protecting the power supply line of the plant by means of a differential magneto-thermal switch with intervention threshold not higher than 30 mA All foreign masses and piping will be connected by means of equipotential pipe to a ground node. -

Page 22: Cleaning
8. CLEANING 8.1 General The firebox and the flues must be periodically cleaned from combustion solid residues (ashes). Keeping the flues free from ashes ensures an effective draught and the best geerator efficiency. Table 8.1 lists the cleaning operations to be carried out in the chronological order. CAUTION !! BEFORE CLEANING, DISCONNECT THE ELECTRIC ENERGY FROM THE GENE- RATOR BY INTERVENING ON THE MAIN SWITCH AND ENSURE THAT THE RESI-... - Page 23 FUEL HOPPER OPERATION: checking and cleaning of the empty hopper from dust and incrustation due to hu- midity and to the type of the used fuel. PERIODICITY: 30 / 60 days NOTES: check the fuel does not contain foreign bodies that could damage the screws. REFERENCE: fig.3.4.1 pos.12 tab.
