Please, read carefully the advice and warnings contained in this section as they provide important indications on the boiler use.
1.2 First start-up. Before the first start-up, please check that the system is properly filled with water and that it has pressure 1 ÷ 1.3 bar, then proceed as follows: • open the gas valve; • turn the selector (36) on the only DHW function or on the DHW/CH function; • Our remote control operation (Optional RC).

2 INSTALLER INSTRUCTIONS 2.1 Boiler installation 2.1.1 General rules The boiler installation is intended to be fixed and it must be carried out by professionally qualified staff, according to the actual national and local law, following all the instructions and rules contained in this manual. The boiler shall be installed in a room free of corrosive steam. After unpacking the boiler, ensure the integrity of the content: in doubt, do not use the apparatus and refer to the supplier.
Clearances shall provide provision for service access and protection from combustible surfaces. Minimum clearances from combustible surfaces shall be 50mm at sides, 300mm from top and 300mm from bottom. ENSURE THAT THE AIR ENTRY IS NOT OBSTRUCTED BY ADJACENT CABINETS OR OTHER STRUCTURES. 2.2 Installation If our accessories are used to install the boiler, read the instructions enclosed carefully. After choosing the suitable position to install the boiler, fit the installation template (see fig. 2).
2.4 Condensate drainage system. The condensate produced inside the boiler must be drained. Therefore the boiler is provided with a condensate trap. The condensate trap fitting is to be connected to a ∅ 32 mm PVC condensate drainage system. It is recommendable to install a further water trap on the condensate drainage system before the condensate reaches the sewer. Only plastic tubes of the standard civil condensate drainage systems are suitable to drain the condensate towards the sewer of the house. 2.
Professionally qualified personnel shall verify that the electric supply system is adequate to the apparatus maximum power (140 W please see the rating plate), and that the wiring section is suitable to the power absorption of the machine. The use of electric adapters, extension cords or sockets are not recommended, but it is convenient to provide the system with a double-pole switch having at least 3 mm spaced electric. Before connecting the boiler, make sure that the power grid and main switch are off.

Turning knob clockwise completely till maximum, there will be a temperature rainsing 25°C. This could will be useful in the mid seasons when the external temperature is high and the flow temperature too low to heat the house. Here are the approximate temperatures set on trimmer P7 if it is used to adjust high or low temperature.
no control on the boiler functions which depend on the control panel commands. If the boiler has to operate at low temperatures and has remote control, simply select the required temperature directly on the remote control unit. When operating with the remote control without other thermostats (single zone system) jumpering must not be used on the room thermostat wires. 2.
An example of a hydraulic diagram for mixed temperature systems is given below. A mixing system as SILE TBA/TBA-M, must be used. The boiler will operate at the best temperature for optimising thermal comfort and energy performance.
2.11 Filling the condensate drainage system. Take off the plug on the condensate drainage system and fill it with water amounting to 1 glass so that flue gases do not come out. Attention. Do not operate the boiler if the condense drainage system is empty. It may cause intoxication from burnt gas. 2.12 System start-up. Before starting up the boiler, check that the relevant actual rules have been performed.
CONDENSA 5.32 III BY PASS II I T A 2.14 Zone system In the hypothesis of a system supplied by several zone valves, they are supposed to be connected correctly to avoid the boiler pump functioning when all valves are closed. The following diagram shows how to connect them. Before connecting, check that the ends of the two wires from the room thermostat are not alive. Diagram available also with a remote control (optional) after configuring the boiler control board as instructions (page.
2.17 Safety valve Hot Water Storage tank (where used) The safety valve with is calibrated at 8 bar pressure. During the heating of the contents a dribble from unloading under certain conditions is predictable and normal. During installation direct the unloading valve to drainage duct. If dribble continue also with hot tank and boiler stop check the supply pressure :if this exceeds 5 bar apply a pressure reducer and check the safety valve to have an efficient drainage.
*** In positioning the terminals, distances must be no less than 500 mm when they are near to materials sensible towards the action of combustible products (i.e.: plastic eaves and gutters, wooden overhangs, etc.) unless suitable protective measures are taken. The boiler is homologated with chimney configuration type: B23P . C13 . C33 . C43 . C53 . C83 2.20 Configuration type B23 open chamber and forced draft.
cutting an extension of 1 m at the required dimension. The air/flue duct must be installed on a perfectly horizontal position since it already has a minimum standard slant which prevents the condensate from dropping and freezing on the ground. The duct will be fixed following the relevant figures. 1. Cut the hole in the wall for the air/flue duct. Its minimum diameter should be sufficient to allow the insertion of a plastic duct (as long as the wall and with ø130 mm) which will be sealed with mortal.

2 1 Display in solar mode: - When solar function starts a solar system icon light up . - For 10 seconds after the solar pump activation, are visualized the temperature collector probe in big digits and the temperature solar tank probe (sanitary probe) in little digits. The solar system works when flat-plate solar collector temperature is higher than the temperature in solar tank in the gauge set in 5 parameter , that defines the temperature difference keeping between collector and tank.

This is a safety parameter which blocks the solar circulator functioning when the tank boiler is greater than the parameter. For example if we set this parameter to 85°C, when the tank exceeds 85°C the circulator functioning will block and thus the amount of heat to the tank. To make these adjustments is necessary respect the following procedure: a) to turn : i. the sanitary knob at half way, ii. the thermo knob at minimum, iii. the selector from Off position to reset.
DIP switch 5: DIP switch 6: to the time and temperature reached. It is set to ON for multi-zone systems controlled by thermostats/programmable thermostats. In this case, the remote control checks the sanitary water temperature and displays the operating status. this must be set to OFF. If accidentally set to ON, it causes error F27 this must be set to OFF if you want to operate the boiler with the remote sanitary tank.

⇒ adjust by turning the screw only 1/8 turn and waiting for at least 1 minute after every turn for the value to stabilise; ⇒ Proceed as follows to check the setting at minimum capacity: ⇒ switch the heating potentiometer to minimum; the boiler is now operating at minimum power ⇒ Adjust the fan rpm to the minimum power using trimmer P2 on the boiler PCB. The rpm are displayed on the front display as shown above when adjusting the fan speed at maximum power.
iii. the selector from the Off position to the Reset position. b) A number for the parameter selected with the sanitary knob is shown on the left of the display in small digits whereas the value is displayed in large digits: maximum heating power is adjusted with parameter 1. c) to modify the desired parameter: turn the thermo knob. The displayed value is a percentage of the maximum power of the generator.
• • • Check the soundness of the gas circuit Check that there is no presence of water leakage from the boiler internal connections Check that the condensing trap is free from obstructions, that there is a sufficient quantity of water inside and that the evacuation of the condense is correct. It Is better to avoid frequently draining of the system unless for specific alterations or repairs. In the areas subjected to freezing, the system should be drained when in disuse.
