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 Check the environmental operating conditions of all parts relevant to installation, referring to the values shown in the techni- cal data table in this booklet. Installation of the appliance when powered by LPG or propane air must comply with the rules regarding gases with a greater density than air (remember, as an example, that it is prohibited to install plants powered with the above-mentioned gas in rooms where the floor is at a lower quota than the country level).
- Page 9 Installation standards This type of installation is possible when permitted by the laws in force in the appliance's country of destination. 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.). 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 10 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 11 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.

- 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 14 In these conditions, previously listed, the appliance is protected against freezing up to an ambient temperature of -5°C. If the appliance is installed in a place where the temperature drops below -5°C, the appliance may freeze. When installing the appliance in locations where the temperature falls below -5°C, insulation of the connection pipes, both DHW and CH, of the condensate drain pipe and the installation of the antifreeze kit is required, respecting all the conditions listed above.

Page 17: Gas Connection
This cock, if supplied by the appliance’s manufacturer, can be directly connected to the appliance (i.e. downstream from the pipes connecting the system to the appliance), according to the manufacturer’s instructions. The Immergas connection unit, supplied as an optional kit, also includes the gas cock, whose installation instructions are provided in the kit. - Page 18 Storage tanks (in case of supply from LPG depot). - New LPG storage tanks may contain residual inert gases (nitrogen) that degrade the mixture delivered to the appliance casing func- tioning anomalies. - Due to the composition of the LPG mixture, layering of the mixture components may occur during the period of storage in the tanks. This can cause a variation in the calorific value of the mixture delivered to the appliance, with subsequent change in its performance.

Page 20: Electrical Connection
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 21 If the power supply cable is damaged, it must be replaced by a special cable or assembly, which are only available from the manufacturer or its Authorised After-Sales Technical Assistance Centre. It is recommended to contact a qualified company (e.g. the Authorised After-Sales Technical Assistance Centre) for replacement to avoid a hazard.
