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.

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.
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 ser vicing manual for fur ther information) FIG. 2.
CENTRAL HEATING Detailed recommendations are given in BS 6798:1987 and BS 5449-1:1990, the following notes are given for general guidance. PIPE WORK: Copper tubing to BS EN 1057:1996 is recommended for water pipes. Jointing should be either with capillary soldered or compression fittings. Where possible pipes should have a gradient to ensure air is carried naturally to air release points and water flows naturally to drain taps.
2.9 FLUE SYSTEM The provision for satisfactory flue termination must be made in accordance with BS 5440-1. The appliance must be installed so that the flue terminal is exposed to outside air. The terminal must not discharge into another room or space such as an outhouse or lean-to. It is important that the position of the terminal allows a free passage of air across it at all times.
In addition, it is also possible to use a split (twin pipe) system by fitting a special adaptor to the flue connector and using the aperture for the air vent intake located on the top part of the combustion chamber. To utilise the air intake it is necessary to: 1. Remove the bottom of the air intake by cutting it with a suitable knife (see FIG. 2.7); 2. Insert the elbow into the air intake until it reaches the lower end. (There is no need to use gaskets or sealing compounds). FIG. 2.7 Ø 80 mm FIG. 2.

3. D.H.W. STORAGE CYLINDER 3.1 2 PORT AND 3 PORT VALVE INSTALLATIONS The microSYSTEM can be connected to a storage cylinder (both open-vented and unvented) for the production of domestic hot water (D.H.W.). Cylinders of different capacities can be used depending on site requirements (see TABLE 3.1 for a selection of ARISTON unvented cylinders). 2 port valve installation 3 port valve installation FIG. 3.1 FIG. 3.2 FIG. 3.

3.2 DOMESTIC HOT WATER PRIORITY KIT Boiler microSYSTEM 15 RFFI The microSYSTEM is able to be connected to a specially designed kit for the management of D.H.W. production. This kit gives priority to production of D.H.W. unlike traditional systems where the boiler power is split between C.H. and D.H.W. This generally enables a smaller storage cylinder to be chosen as the boiler’s full output will be channelled into the cylinder allowing for a quick heat-up.

4.4 INITIAL START-UP 4.5 THE CHECKS TO BE RUN BEFORE INITIAL START-UP ARE AS FOLLOWS: 1. Make sure that: - the screw on the automatic air valve has been loosened when the system is full; - If the water pressure in the system is below 1.
4.7 BOILER SAFETY SYSTEMS The boiler is fitted with the following devices (see section 4.2 for references). 1 - IGNITION FAILURE: This indicates ignition failure when a flame is not detected within 7 seconds of starting an ignition sequence. The L.E.D. “F” will illuminate to signal the shutdown status. The system can be reset by pressing and releasing the button “E” after checking to make sure that the gas cock is open.
