Page 4: Instructions Prior To Installation
1. INSTRUCTIONS PRIOR TO INSTALLATION 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. -
Page 5: Commissioning The Boiler
3. COMMISSIONING THE BOILER To light the boiler correctly, proceed as follows: 1) power the boiler 2) open the gas tap; 3) press the button ( and switch the boiler to Summer ( ), Winter ( ) or heating only ( 4) press the heating circuit ( ) and domestic hot water circuit ( ) temperature adjustment buttons (... -
Page 6: Adjusting Ambient Temperature And Dhw Temperature
4. ADJUSTING AMBIENT TEMPERATURE AND DHW TEMPERATURE The system must be equipped with an ambient thermostat for controlling the room temperature. Adjust the ambient temperature ( ) and the DHW temperature ( ) by pressing the respective buttons ( gure 1). The ignition of the burner is shown on the display with the symbol ( ) as described in section 3.1. -
Page 7: Filling The System
6. FILLING THE SYSTEM WARNING Disconnect the boiler from the mains power supply using the two-pole switch. IMPORTANT: Regularly check that the pressure displayed on the pressure gauge is 0.7 - 1.5 bar, with the boiler cold. In case of overpressure, open the boiler drain tap. In case of insuf cient temperature, open the boiler lling tap ( gure 3). Open the tap very slowly in order to vent the air. -
Page 8: Prolonged Shutdown. Frost Protection (Central Heating Circuit)
9. PROLONGED SHUTDOWN. FROST PROTECTION Do not drain the whole system as lling up with water again causes 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 speci c anti-freeze to the water in the system (e.g.: propylene glycol coupled with corrosion and scale inhibitors). -

Page 12: Installation Of Ue And Air Ducts
16. INSTALLING THE FLUE AND AIR DUCTS Model 24 F - 1.24 F - 1.14 F The boiler is easy and exible 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 ue-air duct. - Page 13 16.1 HORIZONTAL FLUE INSTALLATION OPTIONS L max = 5 m L max = 5 m L max = 4 m L max = 4 m 16.2 LAS FLUE DUCT INSTALLATION OPTIONS L max = 5 m 16.3 VERTICAL FLUE INSTALLATION OPTIONS This type of installation can be carried out on either a at or a pitched roof by tting a ue terminal and a special weathering surround with sleeve (both available on request).
- Page 14 … SEPARATE FLUE AND AIR DUCTS This type of installation makes it possible to discharge exhaust fumes both outside the building and into single ue ducts. Comburent air can be drawn in at a different location from that of the ue terminal. The splitting kit comprises a ue duct adaptor (100/80) and an air duct adaptor.
- Page 15 16.4 DIMENSIONS OF SEPARATE OUTLETS 16.5 SEPARATE HORIZONTAL FLUE TERMINALS INSTALLATION OPTIONS IMPORTANT - Make sure there is a minimum downward slope towards the outside of 1 cm per metre of duct length. If the condensate collection kit is installed, the discharge duct must slope down towards the boiler. L max = 10 m (L1 + L2) max = 30 m N.B.:...

IMPORTANT: if tting a single ue duct, make sure it is adequately insulated (e.g.: with glass wool) wherever the duct passes through building walls. For detailed installation instructions, consult the technical data provided with the accesso- ries. 17. ELECTRICAL CONNECTIONS This machine is only electrically safe if it is correctly connected to an ef cient earth system in compliance with current safety regulations. -
Page 17: Gas Conversion Methods
19. GAS CONVERSION The authorised Technical Assistance Service can convert this boiler to natural gas (G20) or liquid gas (G31). The procedure for calibrating the pressure regulator varies slightly according to the type of gas valve tted (HONEYWELL or SIT, see gure 10).
