PRESENTATION MCR-P 24, MCR-P 24/28 BIC and MCR-P MI boilers are delivered fully assembled and factory tested. They come ready to operate on natural gases; operation on propane is possible by simple adjustment or by conversion kit (available as optional equipment). MCR-P 24 boilers are factory fitted with a heating/dhw reversal valve for connection to an independent hot water calorifier: 2 types of optional DHW calorifiers are available: - 80-litre BMR 80 calorifier to be juxtaposed to the right or left of the boiler: version MCR-P 24/BS 80; - 130-litre SR 130 calorifier to be placed on the floor under the boiler: version MCR-P 24/BS 130. The MCR-P 24/28 BIC version is particularly compact (00x600x450mm) and efficient: DHW production, with *** performance in accordance with EN 13203, is handled by a 40-litre storage calorifier integrated into the boiler, combined with an external plate exchanger with a large exchange surface, a DHW pump and a heating/dhw reversal valve. MCR-P MI boilers are combi boilers and produce large quantities of domestic hot water (*** classification in accordance with the standard EN 13203) thanks to an oversized plate exchanger and very reactive electronics. THEY OFFER HIGH LEVELS OF PERFORMANCE - Efficiency at 40/30 C up to 10% - Efficiency class CE - NOx < 70mg/kWh - NOx classification: 5 in accordance with PR EN 15420 - Very low noise level (see page 5) STRONG POINTS - Particularly compact, light boilers - Perfect adaptation of boiler output to actual needs thanks to the stainless steel gas burner with complete premixing, modulating from 25 to 100% output, fitted with a silencer on the air intake. - Stainless steel exchanger with double external envelope in composite material. - Electronic ignition and ionisation flame check. - Delivered with a 8-litre expansion vessel (no vessel on MCR-P 34/3 MI), automatic air vent, water pressure switch. The MCR-P 24/28 BIC is also fitted with the 7-bar DHW safety valve. - Simple, functional control panel with optional control system offering 3 comfort levels: By room thermostat On/Off By modulating programmable room thermostat. By room thermostat or modulating room thermostat according to the outside temperature. - The module AD 20 (option) combined with a modulating room thermostat (AD 266/AD 265/AD 288 or AD 28) allows the controlling of 2 additional circuits (direct, with mixing valve or for DHW production). - For the various air/flue gas connection options, see page 11.

INFORMATION REQUIRED FOR INSTALLATION LOCATION MCR-P condensing boilers must be installed in premises protected from frost, which can also be ventilated. The IPX4D protection index enables them to be installed in kitchens and bathrooms, excluding protection volumes 1 and 2, however. In order to ensure adequate accessibility around the boiler, we recommend that you respect the minimum dimensions given opposite. Ventilation This must comply with prevailing regulations. * MCR-P 24/28 BIC MCR_F0005B GAS CONNECTION AND ELECTRICAL CONNECTION Comply with prevailing national or even local instructions and regulations. 8
INFORMATION REQUIRED FOR INSTALLATION HYDRAULIC CONNECTIONS Important: The principle of a condensing boiler is to recycle the energy contained in the water vapour in the combustion gases (latent vaporisation heat). Consequently, to achieve an annual operating efficiency in the order of 10%, it is necessary to size the heating surfaces in such a way as to obtain low return temperatures, below the dew point (e.g. underfloor heating, low temperature radiators, etc.) during the entire heating period. MCR-P boilers must only be used in closed-circuit heating installations, previously cleaned to eliminate residues and deposits caused by commissioning the installation. Furthermore, it is important to protect central heating installations against the risk of corrosion, scaling and microbiological growth: the water treatment products used must comply with regulations.

The connection must be removable and the flow of condensates visible. The connections and pipes must be in corrosion-resistant material. MCR_F000A An optional condensates neutralisation system is available (package HC 33 see page 7). STANDARD INSTALLATION DIAGRAMS The examples presented below cannot cover the full range of installation scenarios which may be encountered. Their purpose is to draw the attention to the basic rules to be followed. A certain number of control and safety devices (some of which are already integrated as standard in MCR-P boilers) are represented but it is ultimately up to installers, experts, consultant engineers and design departments to take the final decision on the safety and control devices to be used in the boiler room according to its specificities. In all cases, it is necessary to abide by the codes of practice and prevailing regulations. Attention: For the connection of domestic hot water, a sleeve made of steel, cast iron or any other insulating material must be interposed between the hot water outlet and these pipes to prevent any corrosion to the connections, if the distribution pipes are made of copper.
