Plants with - continuous oxygen intake (e.g. under- proof plastic piping) or - intermittent oxygen intake (e.g. where must be equipped with separate circuits. reated heating water must be tested at testing may be necessary. 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 be fore being recharged! he boiler may only Parts of the boiler which have contact with water are made of copper. On account of the danger of spot corrosion 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 in order to avoid a cor ro sion pro ducts of other materials from the plant. Filling and replacement water: For a plant using Hoval boilers untreated drinking water is generally best suited as quality of the untreated drinking water must be desalinated and/or be treat ed with inhi bitors. he stipulations of EN must be observed. In order to maintain a high level of boiler heat ing surfaces the values given in the table 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 table). water which is used throughout the total service life of the boiler must not exceed three times the water capacity of the plant. Space requirements See Di mensions Heating room Gas boilers cannot be positioned in rooms in which halogen compounds can occur and into Halogen compounds can be caused by clean- and bleaching lyes. Combustion air supply he supply of combustion air must be guaranteed. here must be no possibility to close the air supply opening. An air pipe D = 80 for direct combustion air (air-exhaust system) can be di rectly connected to the boiler. he minimum free cross-section for the follows! Room air-dependent operation A minimal ventilation outlet of at least 150 cm 2 or 2 x 75 cm 2 cross-section is necessary for of boiler output up to 50 kw. For each further kw output 2 cm 2 more crosssection must be provided. Room air-independent operation with separate combustion air pipe to the boiler 0.8 cm 2 per 1 kw of output. he pressure loss in the combustion air pipe must be con sidered for the calculation of the exhaust system. Gas connection Commissioning Stat-up is to be carried out only by a specialist. Burner setting values according to the installation instructions. Immediately in front of the boiler a manual gas shut-off device (valve) must be installed ac cor d ing to relevant regulations.

16 Engineering ype of gas he boiler is only to be operated with the type of gas stated on the rating plate. A gas pressure controller to reduce the boiler inlet pressure must be installed on site for propane. Gas pressure Mud collector return is recommendable. Minimum quantity of rotating water Depending upon type of boiler different mi ni mum quantities of rotating water are de mand ed. See also technical data. During the burner mode the circulation pump must always be in function and the minimum heating water circulation must be guaranteed. Pump after-run time he circulation pump must continue to run for at least 2 minutes each time the burner is switched off (the pump after-run time is included in the boiler control with the opro nic regulation). Heating boiler in the attic If the gas boiler opgas classic is built-in in a guard must be provided. Condensate drainage he condensate from the exhaust system can be discharged through the boiler. A condensate trap is not needed anymore with the exhaust system. sate into the canalisation must be obtained from the responsible authority. A siphon must be installed at the condensate outlet on the gas boiler (included in the boiler scope of delivery). he condensate must be openly lead into the canalisation (funnel). Expansion tank An adequately dimensioned expansion tank must be provided. he expansion tank has to be installed at the connection of expansion tank at the con nec- (see Di mensions ). Starting from 70 C a connecting container is necessary.
