  • Page 4: General Precautions

    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: •...

  • Page 5: Commissioning The Boiler

    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 (yellow, positioned under the boiler); • 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.

  • Page 6: Prolonged Shutdown. Anti-Freeze Protection

    2. PROLONGED SHUTDOWN. ANTI-FREEZE 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).

    Lastly, vent any radiators in the system. BAXI declines all liability for damage deriving from the presence of air bubbles in the primary exchanger due to the incorrect or imprecise observance of the above.

  • Page 9: Installing The Flue

    10. INSTALLING THE FLUE 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 coaxial flue-air duct. The boiler can also be used with separate ducts using the accessory splitting kit.

  • Page 10: Cascade Ducts

    10.3 CASCADE DUCTS This type of duct evacuates the products of combustion of more than one boiler in a cascade connection through a shared fumes collector. The collector may only be used to connect the boilers to the flue duct. Available diameters are: Ø125 mm - Ø160 mm and Ø200 mm.

  • Page 11: Connecting The Room Thermostat

    TERMINAL BLOCK M3 Terminals 1 - 3: not used. Terminal 4 - 5: storage boiler pump connection. Terminal 6 - 7: system heating pump connection (external downline from hydraulic separator). If the appliance is connected to an underfloor system, install a limit thermostat to prevent the latter from overheating. Use the relative cable grommets at the bottom of the boiler to thread the cables through to the terminal blocks.

    15. GAS VALVE CALIBRATION To calibrate the gas valve, enable the calibration function as described in section 12.2 and carry out the following operations: 1) Calibrating MAXIMUM heat output. Check that the measured on the flue duct, with the boiler operating at maximum heat capacity, matches that indicated in table 2 (allowed tolerance +/- 0.5%).

  • Page 18: Adjustment And Safety Devices

    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.
