CONDENSING innovative technology: your HERMANN EURA Condensing. In this booklet you will find also the instruction for the installation, the conduction and the maintenance of the parts, which are stricly connected with the condens. - Page 6 (usually a syphon trap which must be firstly filled with water). The EURA Condensing is equipped with a special device which works dry also, limiting almost completely this risk, although the seal is guaranteed only when it’s filled with liquid.
- Page 7 It is mandatory and necessary to use original flue components, espe- cially designed for EURA Condensing and properly signed, to realize the outlet duct, be- cause they are integral part of the same component. See “Chimney connections” for further details about it.

Original Hermann remote control (optional kit) must NOT be connected to green connector. Special interface card, supplied in the remote control kit, must be used. All low-voltage wirings (e.g. TA, SE and original Hermann remote control) must be kept separate from power supply cables, as to avoid boiler malfunctionings due to electrical noise. - Page 20 We give you some correct and wrong examples of installation of inlet and outlet duct (the slope are voluntarily represented in an exaggerated way). A = Inlet; S = Outlet. 1: the most functional and economic solution is to let the condense come back towards the boiler.

Carefully follow the indications foreseen by the specific laws in force. Place here all necessary advices according to national rules about CHIMNEY CONNECTIONS of CONDENSING boilers The outlet duct is the assembly components necessary to connect the boiler to the point where the flues are discharged, and being an integral part of the appliance, it must be original.

Page 30: Cleaning The Combustion Group
Cleaning the combustion group Switch off the boiler and disconnect it from the electrical supply. Be sure that the parts are not hot and eventually wait the time necessary to cool them; Because some contacts with the fine dust and acid condense may occur, we recom- mend to wear the proper devices for the personal protection (i.e. - Page 31 Remark: an excessive quantity of residual is an indicator of malfunctioning or in any case it is not a normal situation. Locate the reasons and solve the problem, so remove the funnel unscrewing the superior and lateral connectors, and the screw [9] of the bracket support. Accurately clean the funnel and be sure that its inlet pipes [5] and outlet condense [7] are free ( it could be obstructed by the residuals).

Hermann cannot be considered liable for eventual damages caused by not qualified persons. Do not modify default settings if not necessary GENERAL PROCEDURE —... - Page 35 In Eura Condensing boilers this parameter must be kept to 0. 1: Type of gas used: natural gas = 0 / LPG = 1. Factory setup: 0. Since Eura Condensing is forecasted to be used with natural gas only, this parameter must be kept to 0.

— when water pressure is COMPLETELY drained, you can open radiators air vents, to allow air inlet and complete plant draining; — when everything is over, close taps and air vents. In the primary exchanger a certain quantity of water of the heating system remains. If you want to remove the boiler from the wall, we advice you to close with plugs the hydraulic inlet/ outlet heating system connections. - Page 40 Delay before re-ignition after reaching heating flow temperature set: (in minutes, default setting = 3): In heating mode, when boiler reaches set temperature ( ), burner switches off. Then tem- perature drops down and burner ignites again. This parameter sets the minimum delay time between a switching off (at set) and the following re-ignition.
- Page 41 17 Regulation of the inlet temperature with request of the only Secondary room Thermo- stat (TA2) (Company set up = 20 °C). EURA Condensing can manage two room thermostats installed in two distinct zones working with different temperatures. For example ( with opportune hydraulic system devices to send the heating to the various zones) we can foresee a zone heated with slow temperature sys- tems (i.e.

• While flashing, boiler is heating radiators. 17 REMOTE displayed • It is shown only if the original Hermann Remote Control Panel is installed (Remote Con- trol). Most of controls are now available on to remote control only. Please refer to remote control instruction manual. - Page 54 Solution: Wait 20/30 minutes to cool boiler down then press ‘reset’. If block happens again, please contact a [Hermann Technical Centre] [qualified technician] (see Cause 2 also). Cause 2: If the block repeats always and immediately after a heat request (heating or DHW) the safety thermostat on the system return may have triggered.
- Page 55 (radiators included). Anyway, it is recommended to call a [Hermann Technical Centre] [qualified technician] case this operation is very usual. Be careful that if boiler is filled with anti freezing solution, any automatic filling with water will dilute solution.

Page 57: Boiler Inactivity
Boiler inactivity The effects of the periods of inactivity can be relevant in particular situations such as in flats used only for some months per year, most of all in cold places. The user will have to decide to put the boiler in the SAFETY LOCK OUT state disconnecting all the supplies, or to leave it in stand-by and use the Anti Freezing Function. -
Page 58: Eventual Problems
In case of particular water hardness, a water softener must be installed. Do not try to repair boiler by yourself. For any problem related to electric circuit, hydraulic circuit, gas circuit, a Hermann techni- cal centre must be contacted. All boilers must be equipped with original spare parts. -
