1 General This product will be marketed in the following European Union member states : NL - BE - ES - GB - HU - SE with a gas burner of the associated category. 4 Warning The boiler shall be assembled and installed by a qualified professional only. For a proper operating of the boiler, follow carefully the instructions. Symbols used Caution danger Risk of injury and damage to equipment.
2 Description The boilers of the P 520 range are pressurised hot water boilers designed for connecting to a flue pipe which require a separate automatic fuel-oil or gas burner. The useful power of P 520 boilers is between 754 and 1450 kW. Models available Boiler with control panel, which may be fitted with an optional Rematic 2945 C3K control unit for heating only or heating and domestic hot water production.

3 Installing the boiler 3.1 Boiler location For the assembly and because of their design, P 520 boilers require no special base. Their closed furnace system means that the floor need not have refractory properties. All you have to ensure is that the floor can support the weight of the boiler when it is fitted for operation. If the boiler location is not determined precisely, leave enough space around the boiler to facilitate monitoring and maintenance operations. Boiler body * If A = 1.
3.2 Ventilation The location of air inlets in relation to the high ventilation openings shall ensure that the air is renewed in the entire volume of the boiler room. It is in any case imperative to conform to the local regulations in force. Caution: In order to avoid damage to the boiler, it is necessary to prevent the contamination of combustion air by chlorine and/or fluoride compounds, which are particularly corrosive.

Heating return : - 13 to 17 sections : 139.7 - 5’’ - 18 to 25 sections : 159 - 6’’ weld. Heating outlet : - 13 to 17 sections : 139.7 - 5’’ - 18 to 25 sections : 159 - 6’’ weld.
5.2 Important recommendations for connecting the boiler to the heating circuit Installation must be carried out in accordance with the prevailing regulations, the codes of practice and the recommendations in these instructions.
5.3 Filling the system Filling shall be performed with a low flow rate from a low point in the boiler room in order to ensure that all the air in the boiler is bled from the high point of the system. All the pumps must be stopped before filling (included shunt pump(s)).
6 Chimney connection The high-performance features of modern boilers and their use in specific conditions as a result of the advance in burner technology (e.g. first-stage or low modulation range operation) lead to very low flue gas temperatures (<160°C). For this reason : - Use flue gas pipes designed to enable the flow of condensates which may result from such operating modes in order to prevent damage to the chimney. - Install a draining tee at the bottom of the chimney.
7 Fuel-oil or gas connections Refer to the instructions supplied with the burner. 8 Electrical connections Refer to the connection instructions supplied with the control panel.. 9 Maintenance The operations described below shall only be performed with the boiler and power supply off. 9.1 Sweeping The boiler will only operate efficiently if the exchange surfaces are kept clean.
3 4 M000040 M000041 - Remove the baffle plates from the upper flue ways. - Carefully sweep the flue ways with the brush supplied for that purpose. - Brush the baffle plates as well. - If possible, use a vacuum cleaner. - Remove the left and right-hand casing covers. - Remove the top insulating material. 6 5 3 2 1 19 M000043 M000042 - Unfasten the nuts up to the stop. - Push in the handles of the sweeping covers. - Remove the sweeping covers. - Brush the vertical plates.
8 7 19 M000044 - Unscrew the 8 closing nuts and open the furnace door. These 3 screws must not be unfastened in any event. M000045 - Brush out the inside of the furnace. - Clean the soot accumulated in the furnace and lower flue ways with a vacuum cleaner. - Close the lower sweeping doors. - Put back the front casing panels by reversing the removal procedure. 9 1 2 M000046 - Remove the lower rear panels. - Remove the lower rear crosspiece. - Remove the lower insulating material on the rear.
9.2 Cleaning the casing material Use a soapy solution and a sponge only. Rinse with clean water and dry with chamois leather or a soft cloth. 9.3 Precautions required in the case of long boiler stops (one or more years) (one or several years) The boiler and the chimney must be swept carefully. Close all the doors of the boiler to prevent air from circulating inside the boiler. We advise removing the pipe which connects the boiler to the chimney and to close off the nozzle with a cover. 9.
12 Rating plate The rating plate fixed on the side of the boiler during installation is used to identify the boiler correctly and also provides the main specifications of the boiler.
