Engineering Regulations and Guidelines he following regulations and guidelines must be observed: Hoval s technical information and installation instructions. Hoval s hydraulic and technical control regulations. Local building law Fire protection standard DVGW guidelines DIN EN 12828 Heating systems in buildings - Design of hot water systems. DIN EN 12831 Heating systems in buildings - Procedure for calculation of the standard heating capacity VDE 0100 Water quality Heating water he European Standard EN 14868 and the Directive VDI 2035 must be observed. Hoval boilers and calorifiers are designed for heating plants without significant oxygen intake (plant type I according to EN 14868). Plants with - continuous oxygen intake (e.g. underfloor heating systems without diffusion proof plastic piping) or - intermittent oxygen intake (e.g. where frequent refilling is necessary) must be equipped with separate circuits. reated heating water must be tested at least 1 x yearly. According to the inhibitor manufacturer s instructions, more frequent testing may be necessary. A refilling is not necessary if the quality of the heating water in existing installations (e.g. exchange of boiler) conforms to VDI 2035. he Directive VDI 2035 applies equally to the replacement water. New and if applicable existing installations need to be adequately cleaned and flushed before being filled. he boiler may only be fil led after the heating system has been flush ed! Parts of the boiler which are in contact with water are made of ferrous materials. On account of the danger of stress cracking corrosion the chloride, nitrate and sulphate contents of the heating water must not exceed 200 mg/l in total. he ph value of the heating water should lie between 8,3 and 9,5 after 6-12 weeks of heating operation. Filling and replacement water: For a plant using Hoval boilers untreated drink ing water is generally best suited as heat ing medium, i.e. as filling and replacement water. However, the quality of the un treat ed drinking water must fulfil the stand ard set in VDI 2035. Should the mains wa ter available not be suited for use then it must be desalinated and/ or be treated with in hibitors. he stipulations of EN 14868 must be observed. In order to maintain a high level of boiler ef fi ciency and to avoid overheating of the heat ing surfaces the values given in the ta ble should not be exceeded (dependent on boil er performance ratings - for multi-boiler plants rating of smallest boiler applies - and on the water content of the plant). he total amount of filling and replacement water which is used throughout the total service life of the boiler must not exceed three times the water capacity of the plant. Boiler room he boiler room must comply with fire regulations. he combustion air supply must be guaranteed. he air opening should be in the lee of the prevailing wind direction and may not be shuttered in any way. he minimum free opening cross-section is 200 cm 2.

Installation Buffer storage unit and return flow safeguard For the Hoval AgroLyt a buffer storage unit with automatic storage and charging con trol and boiler return flow control must be in stalled. hermal Process Control If a pressurised expansion chamber is in stalled then a thermal process controller must also be installed (in accordance with. SWKI regulation 93-1). Hydraulic switching Please observe the examples for use. Heat distribution For central heating of rooms an automatic temperature regulator with one or more mixing circuits should be installed. Plant with open expansion chamber he height of the plant must be such that at least the required minimum pressure in the suction pipe of the pump is maintained in order to prevent cavitation (see heading circulation pumps - pumps ) Plant with pressurised expansion chamber In accordance with the SWKI regulation 93-1 pressurised expansion chambers are only permissible in combination with a thermal process controller consisting of an integrated heat exchanger in the boiler together with a thermal discharge valve. he thermal process control must be connec ted to the cold water supply. he minimum required flow pressure is 2 bar. Minimum throughput: AgroLyt (20) = 1500 l/h (25) = 1500 l/h (35) = 2000 l/h (50) = 2000 l/h. he cleaning aperture for the connector (top of boiler) must remain easily accessible.

Engineering Chimney / Flue System Connecting pipe Feed the flue pipe connecting increasing bet ween the heating boiler and the chimney with a gradient of 30-45 into the chimney, if possible. For a pipe longer than 1 m thermal insulation is necessary. he connecting pipe must be introduced into the chimney in such a way that no condensate can flow into the heating boiler. he connecting pipe must contain a circular, closable flue gas measurement aperture with an inner diameter of 10-21 mm. he ap er ture must be accessible through the ther mal insulation if present. Position: 2xD D 2D Required draught In calculating the chimney dimensions the chimney draught should be between 0,1 and 0,25 mbar (10-25 Pa). D 1D o reliably prevent the occurrence of excessive flue draught, it is essential to install a damper. he damper ensures a constant flue draught, protection of the heating equipment, effective ventilation of the flue and optimum energy utilisation. his is the only reliable way to protect the boiler against accidental overload. Chimney he Agrolyt must be connected to a chimney (flue gas temperature > 200 C). he effective height of the chimney must be at least 6 m. he chimney outlet should be higher than the roof ridge. he flue gas ducts must be capable of withstanding humidity, acidity and soot combustion and be approved for flue gas temperatures > 160 C. Existing chimneys must be renovated accord ing to the instructions of a chimney con structor. Determination of the flue gas duct crosssection in accordance with EN 13384 Part 1 and 2 A flue gas thermometer (included with the AgroLyt ) must be installed in the connecting pipe. his is necessary in order to maintain a high level of plant efficiency. An auxiliary air flap as chimney damper control is recommended. Non-binding standard values for chimney cross-sections made of chrome steel piping connecting pipe = 1,0. connecting pipe and heating boiler connecting pipe and chimney should be thermally insulated.
