Page 29: Fuel Connections
FuEl CONNECTIONS r INSIEME CONDENS boilers have their fuel connec- tions at the rear. Fuel supply hoses must pass through the gap between the boiler base and the floor before being connected to the fuel pump. If the oil feed system is in negative pressure, the return line must reach the same height as the suction line. -

Page 37: Technical Assistance Service
PREPARING FOR INITIAl START-uP It is essential to perform the following checks before start- ing up or testing the functioning of the boiler. - Check that the water supply and fuel shut-off cocks are open. - Check that the water pressure gauge shows a pressure over 1 bar with the system cold. - Page 38 On models 26 BK and 35 BK: - Turn the (I)Summer/(II)Winter selector to (II) Winter. 40 60 80 - Turn the function selector to ON (II) and make sure that the green power indicator lights. The burner should ignite and remain in operation until the temperature setpoint is reached.
- Page 39 If the problems persist, proceed as follows to make sure that the flue gas thermostat has not tripped. - Wait about 5 minutes, then remove the cover from the flue gas thermostat reset button (8) and push the button. - Wait for the burner to complete the entire start-up cycle again, up to the ignition of the flame.

Page 40: Checks During And After Initial Start-Up
CHECKS DuRING AND AFTER INITIAl START-uP Once the boiler has started up, make sure that it shuts down and re-starts properly when: 40 60 80 - The boiler thermostat and storage cylinder thermostat settings are changed. - The function selector is moved from position (II) to (I) and back. -
Page 41: Temporary Shutdown
TEMPORARY SHuTDOWN If you are going away for a short period of time like a weekend or a short holiday, etc., and outdoor tempera- tures are going to remain above ZERO, proceed as fol- lows: - Turn the function selector to OFF (I) and make sure that the green power indicator goes out. -
Page 42: Maintenance
MAINTENANCE Regular maintenance is a legal requirement. In Italy it is required by Presidential Decree 412 of the 26th August 1993. It is also essential for the safety, efficiency and durability of the boiler. Proper maintenance keeps consumption and emissions down, and ensures that the boiler continues to operate reliably over time. -

Page 48: Disassembling And Cleaning The Boiler
DISASSEMBlING AND ClEANING THE BOIlER Clean the boiler and remove any carbon deposits from the surfaces of the heat exchanger at least once a year. This not only extends the boiler’s working life, but also keeps it efficient in terms of heat output and consump- tion. - Page 49 Proceed as follows on completion of cleaning. - Refit the turbulators (5) in the flue gas pipes, making sure that they are correctly seated - Check the condition of the flame guard (6) and seal (7). Replace as necessary. On completion of cleaning, follow the above steps in the reverse order to refit all removed parts.
- Page 50 Cleaning the condensate drain siphon On the boiler’s right hand side panel: - Unscrew the screw (A). - Remove the access panel (B) to obtain easy access to the condensate drain siphon. - Disconnect the corrugated condensate drain hose (18), and remove the siphon. Unscrew the two caps (19) to disassemble the siphon.
