1.1 GENERAL INSTRUCTIONS

Read the instructions and recommendations in these Installation Instructions carefully to ensure proper installation, use and maintenance of the appliance.

Keep this manual in a safe place. You may need it for your own reference while our Servicing Centre technicians or your installer may need to consult it in the future.

This is an appliance for the production of central heating (C.H.). This appliance must be used only for the purpose for which it is designed.

The manufacturer declines all liability for damage caused by improper or negligent use.

No asbestos or other hazardous materials have been used in the fabrication of this product.

Before connecting the appliance, check that the information shown on the data plate and the table in section 7 comply with the electric, water and gas mains of the property.You will find the data plate on the reverse of the control panel. The gas with which this appliance operates is also shown on the label at the bottom of the boiler.

Do not install this appliance in a damp environment or close to equipment which spray water or other liquids.

Do not place objects on the appliance. Do not allow children or inexperienced persons to use the appliance without

supervision. If you smell gas in the room, do not turn on light switches, use the telephone or any

other object which might cause sparks. Open doors and windows immediately to ventilate the room. Shut the gas mains tap (at or adjacent to the gas meter) or the valve of the gas cylinder and call your Gas Supplier immediately. If you are going away for a long period of time, remember to shut the mains gas tap or the gas cylinder valve.

Always disconnect the appliance either by unplugging it from the mains or tur ning off the mains switch before cleaning the appliance or carrying out maintenance.

In the case of faults or failure, switch off the appliance and turn off the gas tap.Do not tamper with the appliance. For repairs, call your local Authorised Servicing Centre and request the use of original spare parts. For in-guarantee repairs contact MTS (GB) Limited.

Check the following at least once a year:

1 - Check the seals for the water connections;replace any faulty seals. 2 - Check the gas seals;replace any faulty gas seals. 3 - Visual check of the entire unit. 4 - Visual check of the combustion process or analysis of combustion by-products

(see section 4.5) and cleaning of the burner if needed.

5 - If called for by point.3, dismantling and cleaning of the combustion

chamber. 6 - If called for by point.4, dismantling and cleaning of the burner jets. 7 - Visual check of the primary heat exchanger:

- check for overheating in the blade assembly;

- clean the exhaust fan if needed.

8 - Adjustment of the flow rate of the gas:flow rate for lighting, partial load and full

load. 9 - Check of the heating safety systems:

- safety device for maximum temperature (overheat thermostat);

- safety device for maximum pressure (safety valve).

10- Check of the gas safety systems:

- safety device for lack of gas or flame ionisation (detection

electrode);

- safety device for gas cock.

11- Check of the electrical connection (make sure it complies with the instructions

in the manual). 12- General check of the combustion by-products of the discharge/ventilation

system. 13- Check of the general performance of the unit.

The technical information and instructions provided herein below are intended for the installer so that the unit may be installed correctly and safely.

The installation and initial start up of the boiler must be by a CORGI Registered Installer in compliance with the installation standards currently in effect, as well as with any and all local health and safety standards i.e.CORGI .

This appliance must be installed by a competent installer in accordance with current Gas Safety (installation & use) Regulations.

The installation of this appliance must be in accordance with the relevant requirements of the current Gas Safety (installation & use) Regulations, the Local Building Regulations, the current I.E.E. Wiring Regulations, the byelaws of the local water authority, and in Scotland, in accordance with the Building Standards (Scotland) Regulation and Health and Safety document No. 635 “Electricity at work regulations 1989”. Installation should also comply with the following British Standard Codes of Practice:

For safety purposes, have a competent person carefully check the electrical system in the property, as the manufacturer will not be held liable for damage caused by the failure to earth the appliance properly or by anomalies in the supply of power.Make sure that the residential electrical system is adequate for the maximum power absorbed by the unit, which is indicated on the rating plate.In addition, check that the section of cabling is appropriate for the power absorbed by the boiler.

Fasten the boiler in place using the template and anchors supplied with the unit.It is highly recommended that a spirit level be used to position the boiler so that it is perfectly level. For additional information, please consult the instructions contained in the connection kit and the flue kit.

2.2 SITING THE APPLIANCE

The appliance may be installed in any room or indoor area, although particular attention is drawn to the requirements of the current I.E.E.Wiring Regulations, and in Scotland, the electrical provisions of the Building Regulations applicable in Scotland, with respect to the installation of the appliance in a room containing a bath or shower.

Where a room-sealed appliance is installed in a room containing a bath or shower the appliance and any electrical switch or appliance control, utilising mains electricity should be situated so that it cannot be touched by a person using the bath or shower.

The location must permit adequate space for servicing and air circulation around the appliance as indicated in paragraph 2.4. The location must permit the provision of an adequate flue and termination. For unusual locations special procedures may be necessary. BS 6798-1987 gives detailed guidance on this aspect. A compartment used to enclose the appliance must be designed specifically for this purpose. No specific ventilation requirements are needed for the installation within a cupboard. This appliance is not suitable for outdoor installation.

The type C appliances (in which the combustion circuit, air vent intake and combustion chamber are air-tight with respect to the room in which the appliance is installed) can be installed in any type of room.

Secondary ventilation is not required with this boiler.The boiler must be installed on a solid, permanent wall to prevent access from the rear.

The boiler operates with alternating current, as indicated in the technical information table in section 7, where the maximum absorbed power is also indicated. Make sure that the connections for the neutral and live wires correspond to the indications in the diagram.The appliance electrical connections are situated on the reverse of the control panel under the inspection cover (see the servicing manual for further information)

MPORTANT!

In the event that the power supply cord must be changed, replace it with one with the same specifications. Make the connections to the terminal board located within the control panel, as follows:

- The yellow-green wire should be connected to the terminal marked with the “” symbol;

- The blue wire should be connected to the terminal marked “N”;

- The brown wire should be connected to the terminal marked “L”.

Note:The diagrams for the electrical system are indicated in section 2.12.

Warning,this appliance must be earthed.

External wiring to the appliance must be carried out by a competent person and be in accordance with the current I.E.E. Regulations and applicable local regulations.

The microSYSTEM range of boilers are supplied for connection to a 230 V~ 50 Hz supply.

The supply must be fused at 3 A.

The method of connection to the electricity supply must facilitate complete electrical isolation of the appliance, by the use of a fused double pole isolator having a contact separation of at least 3 mm in all poles or alternatively, by means of a 3 A fused three pin plug and unswitched shuttered socket outlet both complying with BS 1363. The point of connection to the Electricity supply must be readily accessible and adjacent to the appliance unless the appliance is installed in a bathroom when this must be sited outside the bathroom (see section 2.2).

2.8 WATER CONNECTIONS

2.7 GAS CONNECTION

The local gas region contractor connects the gas meter to the service pipe. If the gas supply for the boiler serves other appliances ensure that an adequate supply is available both to the boiler and the other appliances when they are in use at the same time. Pipe work must be of an adequate size. Pipes of a smaller size than the boiler inlet connection should not be used.
