    SAFETY SYMBOLS USED GENERIC HAZARD Strictly follow all of the indications next to the pictogram. Failure to follow the indications can generate hazard situations resulting in possible harm to the health of the operator and user in general, and/or property damage. ELECTRICAL HAZARD Strictly follow all of the indications next to the pictogram.

  • Page 7: Unit Installation

    This appliance has been designed for wall mounted installation only, for central heating and production of domestic hot water for domestic use and similar purposes. The place of installation of the appliance and relative Immergas accessories must have suitable features (technical and structur- al), such as to allow for (always in safe, efficient and comfortable conditions): - installation (according to the provisions of technical legislation and technical regulations);...
  • Page 8 The wall surface must be smooth, without any protru- sions or recesses enabling access to the rear part. They are not designed to be installed on plinths or floors (Fig. It is forbidden to install appliances removed from other systems. The manufacturer declines all liability in the event of damage caused by appliances removed from other systems or for any non-conformities with such equipment.
  • Page 9 Keep all combustible material away from the appliance (paper, rags, plastic, polystyrene, etc.). Split exhaust ducts must not pass through walls of combustible material. Do not place household appliances underneath the appliance as they could be damaged if the safety valve intervenes, if the drain trap is blocked, or if there are leaks from the hydraulic connections;...
  • Page 10 Installation standards This appliance can be installed outdoors in a partially protected area. By partially protected area, we mean one in which the unit is not directly exposed to the elements (rain, snow, hail, etc.). This type of installation is possible when permitted by the laws in force in the appliance's country of destination. Installation of gas appliances, flue exhaust pipes and combustion air intake pipes is forbidden in places with a fire risk (for example: garages, closed parking stalls), and in potentially dan- gerous places.
  • Page 11 Installing the wall recessed frame kit must guarantee the boiler stable, efficient support. The recessed frame kit ensures appropriate support only if installed correctly (according to the rules of good practice), following the in- structions on its instructions leaflet. For safety reasons against any leaks it is necessary to plaster the boiler housing in the brick wall. The recessed frame for the boiler is not a supporting structure and must not replace the wall removed.
  • Page 12 Risk of damage due to corrosion caused by unsuitable combustion air and environment. Spray, solvents, chlorine-based detergents, paints, glue, ammonium compounds, powders and similar cause product and flue duct corrosion. Check that combustion air power supply is free from chlorine, sulphur, powders, etc. Make sure that no chemical substances are stored in the place of installation.
  • Page 13 Filling the condensate drain trap When the appliance is switched on for the first time, combustion products come out of the con- densate drain. After a few minutes of operation, check that combustion flue gases are no longer coming out of the condensate drain; this means that the drain trap has filled to a correct con- densate height that the flue gases cannot pass through.

    - 350 mm NOTE: * : This distance is necessary to install the cy- clonic filter with a normal spanner. It can be reduced to 30 mm using a special spanner. Contact the Immergas toll-free number or the Authorised Technical Service Centre.

  • Page 16: Antifreeze Protection

    - The materials used for the central heating circuit of Immergas appliances resist propylene glycol based antifreeze liquids (if the mix- tures are prepared perfectly).

  • Page 17: Installation Inside The Recessed Frame (Optional)

    The brackets (5) used to centre the appliance on the frame and hold it in place stop against the frame (1) so do not require fixing to the frame itself. An optional hose kit is available to connect the cyclonic filter supplied as standard. Contact the Immergas toll-free number or an Author- ised Technical Service Centre.

  • Page 18: Appliance Connection Unit

    APPLIANCE CONNECTION UNIT The connection unit consisting of all the necessary parts to perform the hydraulic and gas system connections of the appliance comes as standard with the boiler, perform the connections in accordance with the type of installation to be made and respecting the arrangement shown in figure 7.

  • Page 19: Gas Connection

    GAS CONNECTION Our appliances are built to work with natural gas (G20), LPG and mixtures of methane and hydrogen at 20% in volume (20%H2NG), re- ferred to the gas distributed in the network. Power supply pipes must be the same as or larger than the appliance fitting. Before connecting the gas line, carefully clean inside all the fuel feed system pipes to remove any residue that could impair ap- pliance efficiency.
  • Page 20 (i.e. downstream from the pipes connecting the system to the appliance), according to the manufacturer’s in- structions. The Immergas connection unit, supplied as standard, also includes the gas isolation valve. In any case, make sure the gas isolation valve is connected properly.

  • Page 21: Hydraulic Connection

    In order to meet the system requirements established by EN 1717 in terms of pollution of drinking water, we recommend installing the IMMERGAS anti-backflow kit to be used upstream of the cold water inlet connection of the appliance. We also recommend using cate- gory 2 heat transfer fluid (e.g.: water+ glycol) in the appliance's primary circuit (C.H.

  • Page 22: Cyclonic Filter Unit

    CYCLONIC FILTER UNIT The magnetic cyclonic filter is supplied as standard on the unit. Allows to detect the ferrous residues present in the system's water. Thanks to the two valves it facilitates maintenance by cleaning the filter without having to empty the circuit. Install the cyclonic filter on the system return connection using the pipes as shown in the figure below (Fig.

  • Page 24: Electrical Connection

    1.10 ELECTRICAL CONNECTION The appliance has an IPX5D protection degree; electrical safety of the appliance is achieved only when it is connected properly to an effi- cient earthing system, as specified by current safety standards. The manufacturer declines any responsibility for damage or physical injury caused by failure to connect the appliance to an ef- ficient earthing system or failure to comply with the IEC reference standards.
  • Page 25 To protect from possible dispersions of DC voltage, it is necessary to provide a type A differen- tial safety device. If the power cable is damaged, contact a qualified company (e.g. the Authorised Technical As- sistance Centre) for its replacement to avoid a hazard. The power supply cable must be laid as shown (Fig.

  • Page 28: External Temperature Probe (Optional)

    The external probe always operates when connected, regardless of the presence or type of room chrono-thermostat used, and can work both in combination with Immergas chrono-thermostats and with remote controls. The correlation between system flow temperature and external temperature is determined by the position of the central heating selector...
