18 Engineering Standards and guidelines he following standards and guidelines must be respected: technical information and installation manual of the Hoval company hydraulic and control technical regulations of the Hoval company local building law fire protection standards DVGW guidelines DIN EN Heating systems in building plans of hot water heating plants DIN EN Heating plants in buildings - procedure for computing the normed heating capacity VDE 0100 Water quality Heating water: Requirements of the water quality: he European Standard EN 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 once 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 he Directive VDI 2035 applies equally to the replacement water. New and if applicable existing installations must be adequately cleaned and flushed be fore being recharged! he boiler may only be filled after the heating system has been flushed. Parts of the boiler which have contact with water are made of ferrous materials. On account of the danger of stress cracking corrosion the chloride, nitrate and sulfate 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 to 12 weeks of heating operation. Filling and replacement water: For a plant using Hoval boilers untreated domestic water is generally best suited as fil ling and replacement water. However, the quality of the untreated domestic water must at least fulfil the standard set in VDI 2035 or be desalinated and/or be treated with inhi bitors. he stipulations of EN must be observed. In order to maintain a high level of boiler ef ficiency and to avoid overheating of the heat ing surfaces the values given in the table should not be exceeded (dependent on boiler 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. Heating system Combustion air he combustion air supply must be warranted. he air opening must not be lockable. Space requirements he cleaning opening on the flue gas outlet must be easily accessible Mounting of insulation For attaching the insulating mats and the casing, it is necessary to have a gap of at least 40 cm at the left and right sides of the boiler and at least 70 cm on the controller side. After assembling of casing it is possible to push the boiler to the wall without distance. Maximum filling quantity without/with demineralisation based on VDI 2035 Carbonate hardness of filling water up to... [mol/m 3 ] 1 < >3.0 f H < >30 d H < >16.8 e H < >21.3 ~mg/l < >300 Conductance 2 < >600 Boiler size of the individual boiler maximum filling quantity without desalination 50 to 200 kw 50 l/kw 20 l/kw 20 l/kw 200 to 600 kw 50 l/kw 50 l/kw 20 l/kw always desalinate 2 boilers can be installed without distance in between, then the thermal insulation and inner casing must be installed first. hen the boilers can be pushed together. (he boiler door on the left boiler shall be swivelled to the left and on the right boiler to the right). Heating armature group If more than 1 armature group is required then the installation should be on the wall with a wall distributor and 3-way mixer valves provided on site. Hydraulic circuit See Controls Oil burner mounting he burner connection plug must be mounted opposite the burner door hinges. It should be possible to swivel the boiler door incl. burner by 90. o change from right to left swivelling is possible on site. Boiler installations with hermocondensor require from the burner to overcome the resistance of the heat exchanger. Electrical connection of the burner Control voltage 1 x 230 V Burner engine 1 x 230 V he burner must be connected to the burner connection plug of the boiler. For safety reasons the electric cable of the burner must be shortened so the plug must be removed when swivelling boiler door. Sound absorption Sound absorption is possible through the following steps: Heating room walls, ceiling and floor should be very solidly built, a sound absorber should be mount ed into the air inlet. Pipe holders and support should be protected by means of anti-vibration sleeves. Install sound absorber hood for burner. If living rooms are located above or under the boiler room, vibration absorbers have to be mounted to the boiler base. Pipes and flue gas tube must be connected flexibly with compensators. Pumps have to be connected with compensators to the pipes. For damping of flame noise it is possible to install a silencer into the flue gas tube (space should be foreseen for later installation). 1 total of alkaline earths 2 If the conductance in µs/cm exceeds the tabular value an analysis of the water is necessary. 18 Subject to modifications,

19 Engineering Chimney/flue gas system Flue gas tube he flue gas tube must be led into the chimney with an angle of If the flue gas tube is longer than 1 m, it must be insulated. he inlet of the flue gas tube into the chimney has to be carried out in such a way that no condensate can flow from the chimney into the flue gas tube and boiler. A lockable flue gas measuring socket with an inner diameter of mm must be fore seen. he socket has to be led over the ther mal insulation. D < 2D 2 x D 1D Chimney he chimney must be humidity-insensitive, acid resistant and suitable for flue gas temperature > 160 C For existing chimney installation the restoration must be carried out according to the in structions of the chimney constructor. Calculation of chimney diameter according to DIN he cross-sections are to be calculated for boilers without draft requirements. D Required chimney diameter Basics: Smooth chimneys made of stainless steel, flue gas tube 2.5 m, Σζ = 2.2, flue gas tube and chimney insulated, height over sea level 1000 m, outside temperature 30 C. Height Chimney and flue gas tube Ø mm 25 m m m m m ype (110) (125) (160) (190) (220) (250) (280) (320) (360) m = effective chimney height Expansion tank/expansion Ideally, the pressure expansion tank should be connected to the heating system as des cribed in our example applications, with a re mov a ble or sealable actuation device. his means that it is not necessary to drain the entire system in order to carry out work on the tank. Safety valve A safety valve an automatic air vent must be installed in the safety flow Subject to modifications,
