    WATER IN CENTRAL HEATING SYSTEMS INTRODUCTION Always comply with the legislation applicable in the It is ABSOLUTELY NECESSARY to treat the water system country of installation. for the heat generator to work properly and to guarantee its service life together with all its components. This not only applies to jobs carried out on existing instal- lations but also on new installations.
  • Page 30 2. The heating systems Topping up should not be dome using an automatic filling system, but rather done manually and should be recorded in the service book. If there are more than one boiler, they must all be put into service either at the same time or with a very short rotation time so as to evenly distribute the limited quantity of initial lime-scale.
  • Page 31 Mistakes to avoid and precautions. From what we have seen it is therefore important to avoid two factors possibly leading to the above mentioned processes i.e. contact between air and water in the installation and regular topping up with fresh water. To eliminate contact between air and water (and to prevent the latter from becoming oxidized), it is necessary: - that the expansion system be a closed vessel, correctly sized and with the correct pre-loading pressure (to be regularly checked);...

    DRAINING THE CONDENSATE Condensate drainage systems must be: - made in such a way as to prevent the leakage of flue and combustion gases into the environment or the sewer system (siphon required) - of the right size and type to ensure the proper drainage of waste liquids without leakage - installed in such a way as to prevent the freezing of the liquid inside under normal operating conditions - mixed for example with domestic waste liquids (from washing machines, dishwashers, etc.) mostly with a standard pH so as to form a buffer solution that can be put in the sewers.

    SYSTEM ANTI-FREEZE PROTECTION The ALU PRO power condensing boilers are fitted with electronics that provide protection against frost. The electronics activate the heating unit if the temperature drops below the minimum threshold. No special anti-frost additives are therefore needed, unless the system is to be completely shut down for an extended period of time.

    ELECTRICAL WIRING The ALU PRO power condensing boilers leave the factory completely cabled. There remain only the connections to the electrical supply, to the room thermostat and to the outdoor temperature sensor. For the connections to any other devices (accessories) see the diagram on the following page. Proceed as follows to access the control panel terminals: - Turn the small panel (1), unscrew the two screws (2) and remove the cover (3).

    CONNECTING THE OUTDOOR TEMPERATURE SENSOR The correct positioning of the outdoor sensor is of fundamental importance for proper climate control operation. The sensor must be installed outside the building to be heated, at approx. 2/3 the height of the NORTH or NORTH WEST façade and far from flues, doors, windows and sunny areas.
  • Page 46: System Filling And Emptying

    SYSTEM FILLING AND EMPTYING The ALU PRO power boilers require a filling system connected to the central heating circuit return line. All the necessary circuit shut-off and drain com- ponents must be provided. LOADING Make sure that the drain cocks (1) are closed before you start loading the system.
