IST 04 C 154 - 01 DRAGO DUAL INSTALLATION, USE AND MAINTENANCE GB Thank you for choosing our boilers. Please read these installation and maintenance instructions with care. Please note that the boiler must only be installed, repaired and serviced by qualified personnel. 2 3 General information for installers, service engineers and users This INSTRUCTION MANUAL, which is an integral and indispen- sable part of the product, must be handed over to the user by the installer and must be kept in a safe place for future reference. The manual must accompany the boiler should it be sold or moved. This boiler must be used for the purpose for which it has been designed. Any other use is con- sidered incorrect and therefore dangerous. The boiler must be installed in com- pliance with applicable laws and standards and according to the manufacturer’s instructions given in this manual. Incorrect installation may cause injury or damage, for which the manufacturer cannot be held liable. Damage or injury caused by incorrect installation or use or failure to obser- ve the manufacturer’s instructions shall relieve the Manufacturer of all liability whether under a contract or not. Before installing the boiler, check that the specification meets the requirements of the system in which it is to be installed. Check that the boiler is intact and that it has not been damaged during transport and handling. Do not install equipment which is clearly damaged or faulty. Do not obstruct the air intake or heat dissipation grates. Only original accessories must be used for all boilers supplied with optionals or kits (including electri- cal ones). All the packaging mate- rials can be recycled and should be sent to specific waste management sites. Keep the packaging out of the reach of children as it constitutes a serious hazard. In the event of a malfunction, switch off the boiler immediately. Do not attempt to make any repairs and contact a qualified technician. Original parts must be used for all repairs to the boiler. Failure to do this may jeopardize the safety of the boiler and create a serious hazard. To guarantee efficiency and cor- rect operation of the boiler, it is legally binding to service the boi- lers once a year according to the schedule indicated in the relevant section of this manual. If the boiler is not used for a certain length of time, switch off the electri- city and fuel supply. Place some calcium carbonate inside the com- bustion chamber to absorb moisture. Should there be a risk of freezing, add anti-freeze. It is not advisable to empty the system as this may result in damage. Use a specific anti-free- ze for multi-metal heating systems. IMPORTANT If there is a smell of gas, when using a gas-fired boiler, always fol- low these rules. - Do not operate any electrical switches or electrical appliances. - Do not light any flames and do not smoke. - Close the main gas tap. - Open all doors and windows wide. - Contact a Service Centre, a quali- fied installer or the gas supply com- pany. Never use a flame to detect a gas leak. WARNING This boiler has been built for instal- lation only in the country indicated on the rating plate. Installation in any other country may cause injury or damage.
