Page 3: General Description
General Description The Ferroli 201 is a wall mounted combination boiler for Central Heating (C.H.) and domestic Hot Water (D.H.W.). The boiler is of light weight construction and the heat exchanger provides Central Heating and Domestic Hot Water from an integrally designed unit. The boiler contains its own expansion vessel for sealed systems. -

Page 8: Installation Details
Installation Details Location of Boiler The installation of the 201 must be on a suitable non-combustible load bearing wall which will provide an adequate fixing for the boiler mounting bracket assembly. A satisfactory flue with a minimum of 600 mm (2 ft.) rising vertically above the draught diverter must also be provided, terminating in a British Gas Approved cowl. - Page 9 Cupboard or compartment air supply: If the appliance is to be installed in a compartment or cupboard if existing, it should be of sufficient size. This compart-ment or cupboard must have permanent air vents for combustion air, flue dilution and cooling purpose!s, the vents being positioned at high and low level.

Boiler in a room Vented to a room Vented to outside Fig. 4 Effect of an extract fan If there is type of extract fan fitted in the premises, there is the possibility with open flued appliances, that if inadequate fresh air vents are not provided, spillage of products from the flue diverter could take place, when the fan is in operation. - Page 11 Central Heating It must be a sealed system. Detailed recommendations are given in BS6798, BS5449, BS6700 and CP342 Part. 2. Pipework not forming part of the useful heating surface should be insulated to prevent any heat losses or possible freezing (i.e. in roof spaces or ventilated underfloor spaces).
- Page 12 1. Filling point C.H. 2. Temporary connection 3. Cold water supply Fig. 6 Provision must be made for replacing water lost from sealed system. Reference should be made to BS6798, for methods of filling and making up sealed systems. There must be no direct connection between the boiler's central heating system and the mains water supply.

Page 15: Unpacking
Note - To mount the boiler on the wall, a two person lift will be needed. UNPACKING The appliance is delivered in two cartons. The large carton contains the boiler, and the Installation/Servicing and Users Instruction. One carton contains the mounting jig assembly, complete with isolating valves, the assembly fixing screws and wall plugs (x4), the boiler mounting nuts and washers (x2) and drilling template. - Page 16 CONNECTING THE BOILER Place the boiler on its back. Remove the boiler base plate, four screws (fig. 11). Remove the plugs fitted to the boiler water connections. Remove the bag of sealing washers from the boiler pipework. Remove the front panel by gripping on both sides and pulling away from the main boiler.

Page 17: Electrical Installation
Fig. 12 Fig. 11 ELECTRICAL INSTALLATION Electrical installation must be carried out by a competent electrician. The appliance is to be connected to a 240 V ~ 50 Hz supply (see fig. 13). The supply fuse rating is 3A. The terminals are accessible after removing the boiler base plate and single screw securing the terminal cover (see fig. -
Page 18: Time Clock
Time Clock A 24 hour time clock is fitted to the boiler to control the central heating, this will come into operation when the selector switch is turned to the position marked “heating timed and hot water”. A Slide switch: set clock - auto - set programme AUTO AUTO B Display. - Page 19 Over ride By pressing the over ride button (E) the timer programme is over ridden ie, if programme is in OFF time it will come ON and if in ON time will go OFF. The timer will revert back to it set programme on reaching the next ON or OFF time. When the programme is on over ride the sign will be shown in the display window (B).
