DESCRIPTION OF SYMBOLS WARNING Risk of damage to or malfunction of the appliance. Pay special attention to the warnings concerning danger to people. DANGER OF BURNS Wait for the appliance to cool down before working on the parts exposed to heat. DANGER - HIGH VOLTAGE Live components - electrocution hazard. DANGER OF FREEZING Possible formation of ice due to low temperatures. IMPORTANT INFORMATION Information to read with particular care as it is useful for the correct operation of the boiler.
GENERAL PRECAUTIONS This boiler has been designed to heat water to a temperature lower than boiling point at atmospheric pressure. It must be connected to a central heating system and to a domestic hot water supply system according to its performance and power output. Before having the boiler installed by a qualified service engineer, make sure the following operations are performed: • Make sure that the boiler is adjusted to use the type of gas delivered by the gas supply.
1. COMMISSIONING THE BOILER To light the boiler correctly, proceed as follows: • • • • Check that the system pressure is correct (section 6); Power the boiler; Open the gas tap; Select the required heating mode (section 1.2). During initial ignition, the burner may not ignite (causing the boiler to shut down) until any air in the gas pipes is vented. In this case, repeat the ignition procedure until gas reaches the burner. To reset boiler operation, press for at least 2 seconds.
2. PROLONGED SHUTDOWN. FROST PROTECTION Do not drain the whole system as filling up with water again could cause unnecessary and harmful scale to build up inside the boiler and the heating elements. If the boiler is not used during winter and is therefore exposed to the danger of frost, add some specific anti-freeze to the water in the system (e.g.: propylene glycol coupled with corrosion and scale inhibitors).
6. FILLING THE SYSTEM The pressure displayed on the pressure gauge has to be between 1 - 1.5 bar, with the system cold. If it is lower, turn the system filling tap installed by the fitter. IMPORTANT: open the tap very slowly in order to vent the air. The boiler is fitted with a hydraulic pressure switch which prevents the boiler from working if there is no water. If pressure drops occur frequently (monthy basis), have the system checked by the AUTHORISED TECHNICAL SERVICE CENTRE. 7.
INSTRUCTIONS PRIOR TO INSTALLATION The following notes and instructions are addressed to installers to allow them to carry out trouble-free installation. Instructions for igniting and using the boiler are contained in the “Instructions for Users” section. The installation must satisfy the requirements of BS and EN standards and local by-laws and technical regulations. Moreover, the installation technician must be qualified to install heating appliances.
10. INSTALLING THE FLUES The boiler is easy and flexible to install thanks to the extensive range of available accessories, as described below. The boiler has been designed for connection to a vertical or horizontal concentric flue. WARNINGS C13, C33 The terminals for separate flues must be fitted in accordance with the BS standard and the Clean Air Act 1993. Detailed instructions are provided with the individual accessories.
11. ELECTRICAL CONNECTIONS This machine is only electrically safe if it is correctly connected to an efficient earth system in compliance with current safety regulations. Connect the boiler to a 230V single-phase earthed power supply using the supplied three core cable, observing correct Live-Neutral polarity. Use a double-pole switch with a contact separation of at least 3 mm. When replacing the power supply cable, fit a harmonised 3x0,75 mm2 cable with a maximum diameter of 8 mm.
.1 CONNECTING THE ROOM THERMOSTAT The connections in terminal block M1 are in high voltage (230 V). Before making connections, make sure the appliance is disconnected from the power supply. Check the polarity: L (LIVE) - N (NEUTRAL).
KEY TO FIGURE MENU 1 2 Enduser Commissioning 3 4 Engineer OEM ALL MODIFIED PARAMETERS SHOULD BE NOTED DOWN IN THE TABLE AT THE END OF THIS MANUAL (page 31). The following procedure is used to access the four boiler programming menus: • from the main menu C. • A and C (hold down for approx. 6 seconds) B menu 1-2-3-4 (see figure to side and key). • C to go back one menu at a time to the main menu.
To connect this accessory, see figure to side (terminals 4-5) and the instructions supplied with the sensor. With the outdoor sensor connected, press buttons on the control panel to move the set climate curve Kt in parallel (see annex “SECTION” F and parameter P03 in the table in section 14). To increase room temperature press +, to decrease press -. SETTING THE “Kt” CLIMATE CURVE To set the required kt climate curve, proceed as follows: • Access the menu as described in section 14. • Select parameter P03.

16. ADJUSTMENT AND SAFETY DEVICES The boiler has been designed in full compliance with European reference standards and in particular is equipped with the following: • Limit thermostat Thanks to a sensor placed on the CH flow line, this thermostat interrupts the flow of gas to the burner if the water in the primary circuit overheats. Under such conditions the boiler is blocked and only after the fault has been eliminated can it be ignited again by pressing . It is forbidden to disable this safety device.
. ANNUAL SERVICING The service must be performed only by qualified and competent staff in accordance with the Gas safety, Installation and use regulations. In UK this person need to be approved by the Health and Safety Executive.
