2 Safety instructions Safety instructions Please follow these safety instructions closely prevent accidents and material losses. Safety instructions explained Danger This symbol warns against the risk of injury.! Please note This symbol warns against the risk of material losses and environmental pollution. Note Details identified by the word "Note" contain additional information. Target group These instructions are exclusively designed for qualified personnel. Work on gas equipment must only be carried out by a qualified gas fitter. Work on electrical equipment must only be carried out by a qualified electrician. The system must be commissioned by the system installer or a qualified person authorised by the installer. Regulations Observe the following when working on this system all legal instructions regarding the prevention of accidents, all legal instructions regarding environmental protection, the Code of Practice of relevant trade associations, all current safety regulations as defined by DIN, EN, DVGW, TRGI, TRF, VDE and all locally applicable standards, Gas Safety (Installation & Use) Regulations the appropriate Building Regulation either the Building regulations, the Building Regulation (Scotland), Building Regulations (Northern Ireland), the Water Fittings Regulation or Water Bylaws in Scotland, the current I.E.E. Wiring Regulations. If you smell gas Danger Escaping gas can lead explosions which may result in serious injury. Never smoke. Prevent naked flames and sparks. Never switch lights or electrical appliances ON or OFF. Close the gas shut-off valve. Open windows and doors. Remove all people from the danger zone. Notify your gas or electricity supplier from outside the building. Shut off the electricity supply the building from a safe place (outside the building).

3 Safety instructions Safety instructions (cont.) If you smell flue gas Danger Flue gas can lead life-threatening poisoning. Shut down the heating system. Ventilate the boiler room. Close all doors leading the living space. Working on the system When using gas as fuel, also close the main gas shut-off valve and safeguard against unauthorised reopening. Isolate the system from the power supply and check that it is no longer 'live', e.g. by removing a separate fuse or by means of a main isolar. Safeguard the system against unauthorised reconnection. Ancillary components, spare and wearing parts Please note! Spare and wearing parts which have not been tested gether with the heating system can compromise its function. Installing non-authorised components and non-approved modifications/conversion can compromise safety and may invalidate our warranty. For replacements, use only original spare parts from Viessmann or those which are approved by Viessmann.! Please note Electronic modules can be damaged by electro-static discharges. Touch earthed objects, such as heating or water pipes, discharge static loads. Repair work! Please note Repairing components which fulfil a safety function can compromise the safe operation of your heating system. Replace faulty components only with original Viessmann spare parts. 3

For oil and gas combustion equipment over 00 kw, according the Sample Combustion Ordinance "FeuVO", an "emergency shutdown" must be installed on site outside the installation room. The national combustion equipment ordinance for your local region must be observed. For combustion equipment EN 5056-, the "emergency shutdown" installed on site must comply with the requirements of EN Install the "emergency shutdown" outside the installation room; it must be able separate all non-earthed conducrs simultaneously with a gap of 3 mm at least. We additionally recommend installing an AC/DC-sensitive RCD (RCD class B ) for DC (fault) currents that can occur with energy-efficient equipment.
