1 General This product will be marketed in the following European Union member states: NL - BE - ES - GB - HU - SE with a gas or oil-burner of the associated category. Warning Directive 97/23/EC Gas and oil boilers with a maximum operating temperature of 110°C and hot water tanks with a maximum operating pressure of 10 bar pertain to article 3.3 of the directive, and therefore, cannot be CEmarked to certify compliance with the directive 97/23 EC.
2 Description The boilers of the P 320 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 320 boilers is between 55 and 280 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 The P320 boiler does not require a special base for its assembly. 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.
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.
5 Hydraulic connections 5.1 Important recommendations on connecting the heating circuit to the boiler and the drinking water system Installation must be carried out in accordance with the prevailing regulations, the codes of practice and the recommendations in these instructions. The expansion vessel must be connected directly to the boiler without valves or stop valves. Example of an installation: The example of an installation shown below does not cover every possible configuration.
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. `Minimum safety valve flowrate as a function of maximum boiler nominal output: Minimum relieving capacity Example Maximum gross boiler output Maximum boiler nominal output is 200 kW.
`Operation with modulating burner - The water temperature in the boiler is maintained at 50°C or more: The burner can modulate down to 30% of the nominal stage - Operation at modulated low temperature (minimum outlet temperature: 30°C) ; The burner can modulate down to 50% of the nominal stage 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.
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 ZRefer to the instructions supplied with the burner. head deflector must be flush with the insulation ofThetheburner burner door.

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. Cleaning the flue gas circuit - Switch off the boiler electrical power supply. - Unhook the front panel.
Positioning of the baffles The first two baffles on the two lower flue ways are fitted with stops to position them in the right place. Cleaning the flue gas box - Remove the left and right cleaning hatches from the flue gas box (2 butterfly screws) and use a vacuum cleaner to remove any soot which has accumulated - Replace the cleaning hatches.
10 Burner maintenance Refer to the instructions supplied with the burner. 11 System maintenance 11.1 Water level Regularly check the level of water in the system and top up if required, taking care that cold water is not added suddenly into the boiler when it is hot. This operation should be required only a few times in each heating season, with very low quantities of water; otherwise, look for the leak and repair it. 11.
