Page 4: Introduction
The new concept of XIGNAL CE is that it is fitted with a microcomputer to regulate the boiler performance through technically sophisticated controls. This guarantees correct and optimum operation while being extremely simple to use. -
Page 5: General Description
GENERAL DESCRIPTION The boiler is able to operate with two types of fuel gas: natural or propane (L.P.G.). The type of gas should be chosen when the boiler is ordered. Conversions can also be carried out during the installation phase .The boiler is controlled by an internal microcomputer and all settings to the regulating systems are carried out on the assembly line by use of software. -

Page 10: Installation Details
Location of Boiler The installation of the XIGNAL CE must be on a suitable non-combustible load bearing wall which will provide an adequate fixing for the boiler mounting bracket assembly. The location should be in an area where the water pipes will not be subjected to frost conditions. -

Page 12: Flue System
Flue system The boiler allows the flue outlet to be taken from the rear of the boiler or from either side. A standard flue length of 0.75 metres is provided. Alternative lengths of two or three metres can be supplied (equivalent to wall thicknesses of up to 565, 1815 and 2815 mm for rear flues and deduct 91 mm plus distance from side wall for side outlet flues). - Page 13 Cold water Additional expansion vessel C.H.

Built-in Central Heating Water Circulating Pump The pump head available for circulating the water is given in fig. 8. N.B. - The pump is factory set at position 3. The pump is a Grundfos type 15-50 UPS series. Grundfos Pump performance graph Note - Minimum flow through boiler heat exchanger at any time should not fall below 6 litres per minute. - Page 15 Installation Note - To mount the boiler on the wall, a two person lift will be needed. UNPACKING The appliance is delivered in 2 cartons. The large carton contains the boiler, the Installation/Servicing and Users Instructions, external and internal sensors. The second 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), drilling template, flue assembly and turret.
- Page 16 Important Note - Always use two spanners to prevent twisting of soft copper pipework on the boiler. Flush out the water system. Note - The maximum inlet cold water pressure must not exceed 10 bar (145 P.S.I.) and a water governor or a pressure reducing valve will be required if the pressure is in excess of 5 bar (72 P.S.I.).
- Page 17 PREPARING THE FLUE ASSEMBLY Rear Flue Outlet (fig. 12) Important - The aluminium flue pipe must protrude into the outside grill by 2 in (50 mm), never cut it to the same length as the plastic air pipe (aluminium flue pipe = plastic air inlet pipe + 50 mm !). Aluminium flue pipe length = Plastic air inlet pipe length plus 50 mm (2") longer.

External sensor location The external sensor should preferably be installed on the North, North-East wall or on the one facing the majority of the main living rooms in the building. The sensor must never be exposed to the first morning sunlight. Where possible, it must never be subjected to direct sunlight and should be protected if necessary. - Page 23 8 Gas conversion Only Qualified Personnel may carry out the following regulating and conversion operations. Ferroli S.p.A. declines all responsibility for damage to persons and/or property caused by unauthorized persons having tampered with the appliance. Proceed with the following conversions if the appliance must be used with a different type of gas.
