Also refer to the Declaration of Conformity. NBN D 5-003 - Natural gas installations NBN D 5-004 - Connection to a natural supply 3. Approvals and notifications The installation of a gas boiler must be declared to and approved by the gas supplier. Please note, local regulations may require third party approval when connecting to a flue gas system or drain condensate into the local sewage system "Where required, inform local representative (i.e. chimney sweeper) before installing the boiler 3.3 Quality of the heating water Use water to drinking water quality when filling and toping up the heating system. Water quality is an important factor to increase the efficiency, safety, reliability and availability of your heating system. Unsuitable or contaminated water can lead to problems or damage of the heat exchanger and water supply caused by i.e. sludge, corrosion and scale build up. Apply the following steps: Thoroughly flush the system before filling Water from wells and springs are not suitable as fill water Consider the total volume of scale introduced into the heating system over its lifetime, by fill and top up water, and protect it against damage with that in mind For systems with a volume 50litres/kW (i.e. when using buffer vessels) the water must be treated. An approved solution is the full removal of salts from the fill and top up water, achieving a conductivity of 0μsiemens/cm (= 0μS/cm). Instead of a the water treatment solution you could install a means of system separation (i.e. plate heat exchanger) directly after the boiler. Please contact the manufacturer of the appliance for additional inhibitors and anti freezes. Always refer to the manufacturer's advice for filling and continuous maintenance when using these solutions. 3.4 Connection to combustion air and flue gas systems Always refer to the latest version of the applicable local standards and regulations Further information about combustion air supply and connection to flue gas systems can be found in chapter <reference in the manual> in this manual. Also refer to the documentation supplied with the flue gas system. 3.5 Room air dependent operation The boiler can be operated room air sealed if room air dependent operation is not desired or possible. Provide sufficient boiler room ventilation when operating the appliance room air dependent Do not obstruct or block any ventilation openings Ventilation openings must always be kept clear 3.6 Flue gas systems type B xx DANGER: Risk to life from flue gas poisoning. Insufficient combustion air supply can lead to flue gas escaping. Ensure combustion air supply Supply and extract vents in doors, windows and walls must not be closed off or reduced in size. Ensure a sufficient combustion air supply, also with equipment installed afterwards: i.e. kitchen extract fans and air conditioning units extracting air to the outside Do not operate the appliance if combustion air supply is insufficient. Type B flue gas systems take combustion air from the boiler room. Flue gas exits the appliance via the flue gas system. Special regulations apply for installations of this type - comply with these requirements. Sufficient combustion air must be available. 3.7 Flue gas systems type C xx Type C flue gas systems take combustion air from outside the building. Flue gas exits the appliance via the flue gas system to the outside. To ensure this, the combustion chamber door is air tight. Therefore always ensure the combustion chamber door is closed when operating the appliance room air sealed. Refer to the installation instructions of the flue gas system when installing the appliance 3.8 Combustion air quality To avoid corrosion, combustion air must be free from aggressive substances (hydrogen halide, chlorines and fluorine). 4 Logano plus GB0 6708065 (04/03)
Pre-installation 4 3.9 Disposal Dispose any part of the heating system via an authorised facility 3.0 Inspection, service and maintenance The heating system should be service regularly for the following reasons: To achieve and maintain a high efficiency and low fuel consumption To ensure operational safety To keep combustion clean and emissions low Service interval NOTICE: Damage to boiler from contaminated combustion air and contaminated air in the vicinity of the appliance!
