PRESENTATION
MODELS AVAILABLE
MCR 24, MCR 24/28 BIC and MCR…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 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 24 + BMR 80;- 130-litre SR 130 calorifier to be placed on the floor under the
boiler: version MCR 24 + SR 130.The MCR 24/28 BIC version is particularly compact (900 x 600 x 450 mm) 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 .. MI boilers are mixed 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 109 %- Efficiency class ★★★★ CE- NOx < 70 mg/kWh- NOx classification: 5 in accordance with PR EN 15420- Noise level in compliance with NRA (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.

- Electronic ignition and ionisation flame check.- Delivered with a mounting frame with prefitted water and gas
valves (including the disconnector), 8-litre expansion vessel (no vessel on MCR 34/39 MI), automatic air vent. The MCR 24/28 BIC is also fitted with the 7-bar DHW safety valve and a flow collector.
- Simple, functional control panel with optional control system offering 2 comfort levels:
• By room thermostat • According to the outside temperature, with the possibility of
also controlling a direct circuit, a circuit with mixing valve by connecting a remote control with specific communication interface and the outside sensor.
- For the various air/flue gas connection options, see page 11.

LOCATION
MCR 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.
VentilationThis must comply with prevailing regulations.
GAS CONNECTION AND ELECTRICAL CONNECTION
Comply with prevailing national or even local instructions and regulations.

INFORMATION REQUIRED FOR INSTALLATION
HYDRAULIC CONNECTIONSImportant: 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 109%, 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 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.
Condensates dischargeThe siphon provided must be connected to the waste water discharge system. The connection must be removable and the flow of condensates visible. The connections and pipes must be in corrosion-resistant material.
An optional condensates neutralisation system is available (package HC 33 see page 7).
STANDARD INSTALLATION DIAGRAMSThe 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 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.
