pump. On the internal heating water outlet there is installed an emergency thermostat , a pressure switch and a clack-valve of the manometer for signalling the pressure in heating system. The emergency thermostat will shut down the wall boiler once the temperature has exceeded 95°C. The pressure switch will shut down the wall boiler once the pressure in heating system has dropped below 0,8 bar. Then in the boiler at the heating water input into the boiler there is installed a safety valve.

The manometer measures the pressure in central heating. By means of a button for setting the heating temperature the user sets the heating water in the system being heated in the range from 35 to 85 °C. The recommended range is from 55 to 85 °C.

BERTELLI automatics function If there is a short-circuited space thermostat, the pump keeps running ( though the boiler is switched off). The pump runs because the boiler still receives the demand on heating and drives the water into the system. Even if the boiler is switched off by the space thermostat the pumps runs after that for 180 seconds.. Parasitic flame ( the ionisation detects the flame before the ignition) can happen at the situations like the gas valve failure.

5. Positioning and installation 5.1. Regulations and guidelines a) regarding the heating system ČSN 060310 : 1998 Central heating and assembly ČSN 060830 : 1996 Safety devices for central heating and HSW heating ČSN EN 483 : 2000 Gaseous fuels boilers for central heating - Boiler in design C with nominal heat intake max. 70 kW ČSN EN 297:1996 Gaseous fuels boilers for central heating - Boiler in design B11 and B11BS with atmospheric burners with nominal heat intake max.
5.2 Installation conditions Only a firm authorized for boilers installation is allowed to install VIADRUS CLEO gas boiler on the basis of the designer ´s approved documentation. Before the installation the assembly firm is obliged to make a correct boiler choice with regard to its functional characteristics and required parameters. The boiler has IP 41 protection which guarantees the resistance against the vertically dripping water. Therefore it can be installed in bathrooms in zone 3 ( in the distance min.
Fig. No. 7 Boiler main dimensions 5.3. Positioning The boiler positioning must correspond to the project documentation. The boiler is positioned in a way making sure that the necessary operating conditions are ensured. (VIADRUS CLEO K ,the boiler with open combustion chamber or VIADRUS CLEO T, the boiler with closed combustion chamber ), this with regard to the volume of brought combustion air and the flue gases exhaustion.
Boiler positioning with regard to the fire regulations: A safe distance from the combustible materials − When installing and operating the boilers it is necessary to keep a safe 200mm distance from combustible materials with combustibility degrees B, C1 a C2 (according to ČSN 06 1008 : 1997) − For easily flammable materials with combustibility degree C3, which burn quickly and by themselves also after the ignition source removal (like paper, millboard, stiff paper, asphalt and tar boards, wood and fibreboar

6. Commissioning 6.1 Connection to the system 6.1.1.Connection to the heating system and filling with water VIADRUS CLEO boiler is designated for heating systems with a forced circulation . The water flow speed can be set by the selection of pump revolutions switch. The heating system must be thoroughly flushed out before filling with water in order to wash out al impurities that can be deposited in distribution pipes or heating bodies and can result in damaging the pump.
Before the gas pipes connection to the boiler the gas pipes must be tested and revised. All gas joints after their connection to the boiler must be tested using a gas detector or foaming solution. Maximum natural gas inlet pressure is 20 mbar. The gas pipes threaded joints must never be strained by additional forces. 6.1.3.Connection to the electricity network The boiler is equipped with a movable three-core cable. It is connected to the network socket positioned maximum 1 m from the boiler.
6.2. Boiler commissioning The whole installation must correspond to the relevant regulations for this equipment. The boiler must be compatible with local connecting conditions (check of adjustment status on the serial number plate ). The boiler commissioning can only be done by organizations authorized for it and trained by the manufacturer.

is obliged to acquaint the user with the boiler operation. The user by his signature in the guarantee certificate confirms that he was acquainted with boiler operation. The boiler itself is in operation secured against the dangerous conditions. But it cannot prevent from the failures the reason of which isn’t included in the boiler mechanism.
Behaviour in case of a failure: In case of a flame simulation the ignition is prevented. Note: If GMF unit at the flame control detects the flame simulation, it reports the defect and if the simulation lasts for longer than 15 seconds the demand on heat is stopped (the heat is switched off by the relay related to the heat demand) and a new ignition can only be attempted after the system reset via the regimes position switch.
The boiler is fully automatic and is isn’t recommended to disconnect it from electricity The boiler is equipped with automatic protection against freezing It is forbidden to interfere with the secured parts Close to the boiler and smoke flues there must never be put, stored or hung any objects made of combustible materials ( the safe distance between the appliance and the combustible materials in the direction of the main radiation is 50 mm, in other directions 10 mm) There
