1.2.- INTRODUCTION The Fagor FEB-20E is a wall hung, room sealed, fan assisted, microprocessor controlled, fully modulating gas combination boiler for providing both central heating and domestic hot water. The maximum heat output in either heating or hot water mode is 23.7kW and priority is always given to the supply of hot water.
Page 4 1.5.- HOT WATER AND CENTRAL HEATING SERVICE Turn the main control switch to the winter setting. The burner will automatically fire up. By means of the central heat- ing temperature selector control knob,any water temperature of between 60 and 85°C may be selected. The boiler will remain on until the temperature selected on the room thermostat or on the boiler itself is reached.
Page 5 APPLIANCE SAFETY LOCK-OUT This boiler has a cut-out indicator built in to it. Whenever a malfunction is detected in the ignition of the boil- er, the boiler switches off automatically and the cut-out indicator lights up (red indicator light) To reset the boil- er press the restart switch.

4.- GENERAL INSTALLATION REQUIREMENTS 4.1 STATUTORY REQUIREMENTS GAS SAFETY (INSTALLATION AND USE) REGULATIONS 1998 (As amended). It is the law that all gas appliances must be installed by a registered person, in accordance with the above regulations. Failure to install appliances correctly could lead to prosecution. It is in your own interest, and that of safety, to ensure that the law is complied with.
Page 11 4.3 FLUE TERMINAL POSITION - The boiler MUST be installed so that the terminal is exposed to the external air. - It is important that the position of the terminal allows free passage of air across it at all times. - It is ESSENTIAL TO ENSURE, in practice that products of combustion discharging from the terminal can- not re-enter the building, or any other adjacent building, through ventilators, windows, doors, other sources of natural air infiltration, or forced ventilation/air conditioning.
Page 12: Ventilation Requirements
4.4 VENTILATION REQUIREMENTS The following notes are for general guidance: - It is not necessary to have a purpose provided air vent in the room or internal space in which the appliance is installed. - If the boiler is to be built into a small cupboard or compartment (i.e. at minimum clearances)and overheat- ing can be forseen (i.e.
Page 13: Expansion Vessel
- A heating by-pass should be fitted to ensure that the above condition is satisfied. If thermostatic radiator valves are to be installed, at least one radiator should be without a thermostatic valve (usually the bathroom radiator). - A sealed system must only be filled by a competent person using the approved method shown. - The following paragraphs outline the specifications of the items fitted to the boiler.

5.- INSTALLATION INSTRUCTIONS 5.1 BOILER PACKAGING The boilers are supplied in different packagings: - Boiler - 1m flue system (separate packaging) 5.2 FITTING THE BOILER. - Decide where the boiler is to be fixed on the wall taking into account the installation requirements detailed in section 4.2 and the clearances and dimensions described in the technical data.
Page 15 5.3 WIRING INSTRUCTIONS Warning: observe the usual precautions to ensure that the electricity supply is isolated before commencing any installation or service work. - The appliance is fitted with a flying lead for 230 V ~ 50 Hz. This should be wired as described in section 4.5 electricity supply. Note: The ignition and flame control by ionisation circuit is polarised.
Page 16 5.5 AIR/FLUE SYSTEM The FEB20E boiler comes supplied with a Ø 60 - 100mm coaxial air/flue kit. The maximum length of the combustion and intake pipes which may be used with the FEB20E boiler is three meters, measured from the 90° bend. Each extra 90° bend or two 45° bends, reduces the available length by 0.8m.
Page 17: Commissioning Instructions
6.- COMMISSIONING INSTRUCTIONS Before commissioning the appliance, the whole gas installation including the meter MUST be purged and test- ed for gas soundness. IMPORTANT: open all doors and windows, extinguish naked lights, and DO NOT SMOKE whilst purg- ing the gas line. Before commencing the commissioning procedure, ensure that the central heating system and the domestic hot and cold water system have been flushed.

Page 19: Routine Servicing Instructions
6.6 FINAL CHECKS - Re-light and test for gas soundness - Set the C.H. and D.H.W. temperature selectors to the required settings. - Ensure that the time clock and/or room stat (if fitted) are set to the required setting (s). 6.7 USER’S INSTRUCTIONS Upon completion of testing the system, the installer should: - Give the ‘users Instructions’...
Page 20 7.2 BURNER AND HEAT EXCHANGER INSPECTION AND CLEANING The front of the sealed air box must first be removed (6 screws) and care should be taken to avoid damag- ing the seal. The combustion chamber cover can then be removed (4 screws) taking care not to damage the delicate insulation material inside.

Page 22: Fault Finding
SELF DIAGNOSTIC FAULT CODES The FEB-20E has a built in self diagnostic fault finding system incorporated into the P.C.B. Should a fault develop on the boiler which could cause a situation liable for the operation of the boiler to become unsafe, then the boiler will fail safe by locking-out which is displayed via the 'red neon' on the control panel.
