3.2. Regulatory installation requirements outside UK.

Installation and maintenance of the unit must be performed by a qualified professional in accordance with all applicable rules and regulations and trade practices of the country in which the boiler is installed. For Switzerland, note in particular Gas Boiler Directives G1 and G3 and those of the local (canton) authorities (e.g. fire and police regulations).


3.3. Accessibility. Sufficient clearance must be provided to facilitate servicing on the boiler. Minimum clearances must be provided on the sides, free of all obstacles (partitions; pipes; other boiler; …) to ensure that the right and left exchanger doors can be opened. See dia below. For models M116 to M180, the minimum height above the boiler is Z + 50 mm (see « dimensional characteristics » section); this area must remain free of all obstacles to allow inspection and cleaning of burner. For models M330 to M450, the minimum height above the boiler is Z + 50 mm (see “dimensional characteristics” section). This height is defined by a burner removal tool (supplied). When installing the boiler, a tool installation test must be performed to ensure that the necessary height under the ceiling for use of the tool has been observed. This area must always remain free of all obstacles to allow inspection and cleaning of the burner. Failure to observe these requirements will result in LOSS OF WARRANTY. The M Series boilers must not be installed on a combustible surface (wood floor, plastic floor covering, etc.).

3.4. Electromagnetic compatibility.

The M Series boilers satisfy the requirements of the European directive concerning electromagnetic compatibility in a residential, commercial and light industry environment.

3.5. Electrical connection. Unlock the front panel (item �), by turning the screw located at the middle by at least two turns. Open the front panel. The control panel is accessed by opening and removing the left casing door (single hinge at rear part) (left door not shown). Remove the screws (item �), then remove the control panel cover (item �). CAUTION : The area volume located above the boiler must remain free of all obstacles to allow inspections on the burner (see chapter 8.2 – Cleaning the burner)

To the left of the control panel, use the cable glands (item �) to run the power supply, alarm transfer and circulator control cables (High current). To the right of the control panel, use the cable glands (item �) to run the power supply, sensor and other low voltage signal cables (Low current). The cable/wire ways can be mounted at the locations where the cables pass; be careful not to mount wire/ways in such a way that they interfere with removal of the boiler roof. For connection, observe wiring diagram specifications, in particular, phase, neutral and ground polarities (see figure on next page). Boiler must be properly connected to ground and satisfy the requirements of standards in the country. For electrical connection characteristics, see table in “Technical Characteristics” chapter. It is highly advised to equip the electric installation with a differential protection of 30 mA. To envisage a double-pole switch on the power supply boiler.

3.6. Gas supply.

Prior to actual commissioning, check that the natural gas supply corresponds to the boiler’s nominal pressure indicated on the nameplate (20mbar). Before supplying the installation with gas, check that the various connections are properly executed and that there are no leaks. In particular, check that a removable coupling is provided between the sectional valve and the gas supply connection on the boiler. To measure the upstream pressure, use the pressure connection available on the connection flange when the boiler is operating (“Upstream pressure” connector). CAUTION : The gas line connection must not be subject to any mechanical stress (risk of

loss of tightness on gas valve). If the gas network used is a 300 mbar system, check that there is a pressure regulator and a gas filter upstream.

The gas valve is factory-adjusted for type G20 gas.


M330-M390

Model M450


3.7. Hydraulic circuits.

A « technical requirements book » is supplied with the boiler. This book gives the hydraulic diagrams which are acceptable for correct operation of the boiler. The hydraulic installation must comply with one of these diagrams. The boiler and its installation must be equipped with the following:

• safety valve calibrated for 4 bars for the models M116-M145-M180 et calibrated for 6 bar for the models M330-390-M450 on outlet connection sleeve provided for this purpose,

• isolating valve on outlet and return connections; surge tank, • an expansion vessel, • check valve (supplied with boiler), • a purging. (certificate)

The water flow of the boiler must be, at the minimum, equal to P/20 with P: power supplied, expressed in Th/h. The circulator must be sized taking account of the maximum power supplied. If the circulator is replaced, you must use the genuine spare part specified in the list of spare parts (see section 10). Filling with water The characteristics of the water used, as of commissioning and for the entire service life of the boilers must comply with the following values:

• Filling water When filling a new installation, or when it has been completely drained, the filling water must satisfy the following characteristics:

Hardness : < 100 mg/l CaCO3 (dissolved Calcuim Carbonate)

• Topping-up water A significant addition of raw water would result in significant scale deposits which could cause overheating and subsequent boiler failure. Special monitoring of the supply water is required and use of a water meter is mandatory. The topping-up water must satisfy the following requirement:

Hardness : < 10 mg/l CaCO3

• System water The system water can be the cause of corrosion due to:

The acidity of the medium, Presence of oxygen, The non homogeneity of the metals used.

To avoid these problems from occurring, the system water must be treated to ensure the following requirements:

PH : 8.2 to 9.5 Oxygen reducer: in excess.

The chemical products used must be implemented methodically and rigorously. We recommend calling in specialized companies for water treatment questions. These specialized companies will be able to propose:

The appropriate treatment in accordance with the characteristics of the installation, A service contract for monitoring and ensuring the result.

Where renovation of an existing old boiler system is concerned, prior to installing the new boilers, the installation must be flushed.

• The use of glycol water is prohibited.


After filling with water :

• Check the water pressure on the pressure gauge (not supplied): For models M118-M145-M180, the water pressure should be at 4 bars max. when hot and at 1 bar minimum when cold, For models M330-M390-M450 the water pressure should be at 6 bars max. when hot and at 1 bar minimum when cold. • Check that the boiler and its installation are properly bled before boiler operation.

3.8. Flue Gas.

The dimensions of the flue conduits should be calculated on the basis of a flue gas pressure at the boiler outlet equal to 0 Pa. The flue exhaust conduits must be made of a condensate-resistant material for condensates which can form during boiler operation. These materials must also be capable of withstanding smoke temperatures of up to 160°C. The conduits should contain no horizontal sections, so as to avoid condensate retention. Check that the combustion gas exhaust is formed by a tight conduit equipped with a tight condensate exhaust connection (see diagram below) M Series boilers are very efficient and therefore their flue gas temperatures are very low. The boiler flue outlet must consequently be oriented with a positive slope so to ensure a sufficient draft It is also necessary to follow local legislation for chimney installations. IMPORTANT: If several boilers are connected to a single flue, check: 1. That the flue is not pressurized, with all boilers operating. 2. If one of the boilers is stopped, that the others do not discharge into the stopped boiler

Example of advised configurations :

3.9. Ventilation.

Check that the upper and lower ventilations exist, that they comply with the applicable regulations, and are not obstructed.

3.10. Evacuation of condensates. The condensates must be evacuated to the drain by means of a PVC pipe (min. diameter 32 mm) since the condensates are acid and aggressive (pH between 3 and 5). An adequate slope of at least 3% should be provided to ensure proper condensate evacuation. Neutralize the condensates before evacuation in accordance with applicable regulations.

6. Commissioning.

6.1. Checks before starting up boiler.

Check hydraulic balancing of boilers. Check that pressure when cold is at least 1 bar and that boiler is equipped with a safety valve. Check a pressure regulator was installed if the network gas is to 300 mbar For a renovation, check that the system has been properly flushed.

6.2. Startup. Before packaging, all boilers are tested in factory with group H natural gas (type G20) during which all the adjustments are performed. For this reason, startup is limited to the following points: The power is limited to 65% of its rated value and the maximum temperature is also limited to 70°C up to commissioning. It is strongly recommended the commissioning procedure to be performed by our Customer Technical Assistance Department. Provisional commissioning can be performed as follows :

1. Switch on the main power switch. 2. Initiate a heat request in comfort mode using the customer interface (see “Interface presentation”

paragraph). 3. Once the burner is operating, check the tightness of the gas line couplings using a non

combustible product. Check the performance of the combustion (via a calibrated combustion analyzer).

4. Set the clock to the correct time (Refer to the client parameter summary table at the end of this manual.)

Any tampering or interference with sealed components will result in loss of warranty.

7. Checks to be performed after startup.

7.1. Condensate drain.

During inspections, check that the condensate drain is not obstructed, either boiler side or pipe side.

7.2. Gas supply.

Check that the gas supply pipe has the correct diameter.

All the boilers must be abruptly stopped together using the main circuit-breaker of the heating system to check that the safety device of the gas pressure regulator station does not trip.

If the device trips, the gas supply pipe is too small. Following this procedure, re-engage the circuit-breaker. The boilers should automatically start up again; contact the gas pressure regulator station supplier.


8. Maintenance operations. The maintenance operations must be performed by a qualified professional. Before proceeding with the operations listed below:

Set the main switch to the off position. Close the gas supply shutoff valve. Hydraulically isolate the boiler.
