1. CHARACTERISTICS AND TECHNICAL DATA

1.1 Introduction

Dear Customer,

Thank you for having chosen the Econcept 50 A, the latest generation of FERROLI wall-hung boiler, featuring

advanced design and cutting-edge technology.

The Econcept 50 A is a pre-mix condensing thermal generator for heating , with very high thermal efficiency

and very low emissions, fired by natural gas or LPG.

The boiler can be connected with external DHW storage.

The boiler control and regulation system is microprocessor-based, with advanced self-diagnostics. The user

interface, made up of a keypad and display, is user-friendly, and shows the operating status of the appliance

at all times. (The operating parameters and the data logs are saved internally and can be called up using the

Personal Computer interface to simplify Service operations).

The heat output is regulated continuously across the entire operating range (also with DHW storage), with

temperature-scrolling climate control, which automatically adapts the operating mode to the characteristics

of the internal and external environment, of the building and its location, using external and internal sensors

(optional extra).

1.3 Ignition and Shut-down

Ignition

Check that any shut-off valves in the heating system and domestic hot water circuit outside of the boiler are

open. Open the gas control upstream from boiler and press the main switch. The boiler will perform a self-

test cycle lasting approximately one minute, at the end of which it is ready for operation. The ignition and

shut-down of the burner assembly are completely automatic operations, which depend on the requirements

of the heating system or domestic hot water circuit (display should read "FHI" during test).

1.4 Regulations

Setting the heating system temperature

Set, using the room thermostat or remote control, the desired temperature inside the rooms. When acting

on the room thermostat, the boiler is turned on and the heating system water is brought to the central heating

outlet set temperature or calculated temperature (with temperature scrolling active). On reaching the

required temperature inside the rooms, the boiler will switch off.

If no room thermostat or remote control is installed, the boiler will maintain the heating system temperature

at the central heating outlet setpoint.

To set the central heating outlet temperature, access the operating menu, and using the button display

parameter 1 – central heating outlet temperature. On pressing one of the buttons the display will start

to flash, showing the outlet temperature setpoint. Use the buttons to set the required value. To

activate the new value, press the button . To cancel the setting, do not press the button , and press

the button .

Shut-down

In the event of extended periods of inactivity close the gas control upstream from the boiler and disconnect

the electrical power supply to the appliance. In this case, the boiler antifreeze protection function is also

disabled; this function switches on the burner assembly when the heating system temperature falls below

5°C.

For extended periods of inactivity during the winter months, in order to avoid damage due to

freezing, all the water should be drained from the boiler, both the domestic hot water and the heating

system; alternatively, drain only the domestic hot water and introduce antifreeze into the heating

system.

For short periods of inactiviti leave the power and gas turned on, the frost protection will activate

if the appliance falls below 5°C, however, this will only protect the appliance. For system protection

internal and external frost stat.

1.5 Maintenance

This appliance must be serviced anually by an approved corgi engineer.

The casing, the control panel and the aesthetic parts of the boiler can be cleaned using a soft and damp cloth.

Do not use abrasives or solvents.

1.6 Fault codes

In the event of operating problems, the display flashes and shows the code identifying the fault code.

The display D1 is marked by the letter “F” and will temporary shut-down, this will reset automatically as soon

as the value returns within the boiler’s normal operating range.

The display marked by the letter “A” causes a shut-down of the boiler which can be reset by the user. To reset

operation, press the (reset) button.

If the problem persists, or for diagnosis if the fault codes (page 26), please refer to the “troubleshooting”

chapter in this manual for more details.

Outside temperature compensation

When the (optional) external probe is installed, the boiler regulation system functions in “Outside

temperature compensation” mode. In this mode, the temperature of the heating system is regulated

according to the external climatic conditions, so as to guarantee a high degree of comfort and energy saving

all year round. Specifically, when the external temperature falls, the central heating outlet temperature is

increased, according to a pre-determined “compensation curve”.

In this mode, the temperature set in parameter 1 of the operating menu becomes the maximum central

heating outlet temperature. This should be set to Maximum to allow the system to regulate over the entire

working range.

The boiler must be set during installation by qualified personnel. Other minor modifications can be made by

the user to improve the level of comfort: the compensation curve can in fact be modified by accessing the

operating menu with the button and scrolling the menu, again using the button, to parameter 9.

The set compensation curve is displayed (refer to graph below). Pressing one of the buttons the display

starts to flash; use the buttons to set the required value. To activate the new curve, press the button

. To cancel the setting, do not press the button, and press the button .

If the ambient temperature is lower than the required value, it is suggested to set a higher curve, and vice-

versa. Proceed with single unit increments or decreases, and check the results in the room.

2.1 General Instructions

Gas Safety (Installation & Use) Regulations: 1996

In the interest of safety, it is the law that all gas appliances are installed by a competent person in accordance

with the above Regulations, Building Regulations/Building Standards Scotland, Codes of Practice, current

I.E.E. Regulations and the byelaws of the Local Water Undertaking. Failure to comply with the Regulations

may lead to prosecution; it is your responsibility to ensure that the law is complied with.

N.B. For Northern Ireland the rules in force apply.

IMPORTANT: If the boiler is to be fitted in a timber framed building it should be fitted in accordance with

the Institute of Gas Engineers document IGE/UP/7. If in doubt advice should be sought from the Local

Supplier.

2.2 Positioning and wall mounting

The place of installation must be free of flammable objects or materials, corrosive gas, dust or volatile

substances. The environment must be dry and not exposed to rain, snow or frost.

The installation of the ECONCEPT 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. In siting the boiler the

following limitations must be observed.

The boiler may be installed in any room or internal space,

although particular attention is drawn to the requirements of

the current I.E.E. wiring regulations and in Scotland the

electrical provisions of the building regulations applicable in

Scotland, with respect to the installation of the boiler in a

room or internal space containing a bath or shower.

Wherea room sealed applianceis installed in aroom containing

a bath or shower any electrical switch or appliance control

utilising mains electricity must be situated so that it cannot be

touched by a person using the bath or shower.

The boiler is supplied ready for wall-hung installation. The

rear frame of the appliance has a series of slots for fastening

it to the wall, using screws with metal wall plugs. The fastening

to the wall must provide stable and effective support of the

appliance.

If the appliance is enclosed in a cabinet or alongside another

appliance, space must be allowed for normal maintenance

operations. Fig. 2 shows the minimum and recommended

space to be left free around the appliance.

WARNING!! This appliance must be installed in a

roomwithsufficient ventilation, to avoid dangerous

conditions arising in the event of, even minor, gas

leaks. These safety standards are imposed by the

EEC Directive no. 09/396 for all gas appliances,

including the so-called sealed appliances.

2.3 Connection to the hydraulic system

Make the connections to the corresponding couplings, according to the positions indicated in Fig. 3.

The discharge of the safety valve must be

connected to a funnel or collection pipe, to

discarge against a wall approx 300mm from

ground level.

Make the connections to the boiler so as its

internal pipes are not subject to stress.

Note: Caution must be taken to ensure the

discarge pipe cannot cause damage to

personsenpropertyin the event of discharge.

The appliance is not supplied with an

expansion vessel, and therefore such

device must be connected by the

installer. Please note that the

pressure in the system, when cold,

must be between 0.5 and 1 bar.

Water treatment

If water treatment is used Ferroli Limited

recommend only the use of Fernox or Sentinel water treatment products, which must be used in accordance

with the manufacturers instructions. For further information contact:

Feronx Manufacturing Co. LTD. Sentinel Division

Tandern house, Marlowe way Betz Dearborn LTD

Croydon, surrey, CRO 4YS Widnes, Cheshire WA8 8ND

Tel: 0870 5601 5000 Tel: 0151 424 5351

Note:

•If the boiler is installed in an existing system any unsuitable additives must be removed by thorough

cleasing. All systems should be cleansed according to B.S. 7593.

•In hard water areas treatment to prevent lime scale may be necessary.

•It is important that the correct concentration of the water treatment product is maintained in

accordance with the manufacturers instructions.

Water System

Note The boiler is designed for sealed systems only and must NOT be used on open vented systems.

Central Heating

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). Drain taps should be positioned at the lowest point of the

system in accessible locations to permit the whole system to be drained down. The drain taps should be in

accordance with BS2879. Copper tubing to BS2871, Part 1 is recommended for water carrying pipework.

Pipework in horizontal runs should have a gradient where possible to facilitate the removal of air. Ensure that

the boiler heat exchanger is not a natural point for air collection.
