Children shall not play with the appliance. Cleaning and user maintenance shall not be made by children without supervision.

DANGER

If you smell gas:

1. Do not use a naked flame, do not smoke, do not operate electrical contacts or switches ( doorbell, light, motor, lift, etc..).

2. Shut off the gas supply.

3. Open the windows.

4. Trace possible leaks and seal them immediately.

5. If the gas leak is before the gas meter, contact the gas supplier.

DANGER

If you smell flue gases:

1. Switch the appliance off.

2. Open the windows.

3. Trace possible leaks and seal them immediately.

WARNING

4 Installation and maintenance of the boiler

must be carried out by a qualified professional in compliance with prevailing local and national regulations.

4 When working on the boiler, always

disconnect the boiler from the mains and close the main gas inlet valve.

4 After maintenance or repair work, check all

installations to ensure that there are no leaks.

CAUTION

The boiler must be installed in a frost-free environment.

Keep this document close to the place where the boiler is installed.

Casing components

Only remove the casing for maintenance and repair operations. Put the casing back in place after maintenance and repair operations.

Instructions stickers

The instructions and warnings affixed to the appliance must never be removed or covered and must remain legible during the entire lifespan of the appliance. Immediately replace damaged or illegible instructions and warning stickers.

Modifications

4. Technical description

4.3.2. Circulation pump

The boiler is fitted with a modulating pump which is regulated by the control panel as a function of ΔT.

The graph shows the manometric height at various outputs. The parameters MIN.PUMP SPEED and MAX.PUMP SPEED are used to modify the pump settings.

4 If flow noise can be heard in the system, it is possible to reduce

the maximum pump speed with the parameter MAX.PUMP SPEED (First of all, vent the heating system).

4 If circulation in the radiators is too low or the radiators do not fully

heat up, increase the minimum pump speed with the parameter

MIN.PUMP SPEED.

4.3.3. Water flow rate

15/03/2016 - 300026081-001-08

The boiler’s modulating control system limits the maximum difference in temperature between the heating flow and return and the maximum speed at which the flow temperature increases. In this way, the boiler does not require a minimum water flow rate.

5.3.2. Positioning of the appliance

(1)

Minimum recommended distance

4 Before mounting the boiler, decide on the ideal position for

mounting, bearing the Directives and the dimensions of the appliance in mind.

4 When choosing the position for mounting the boiler, bear in mind

the authorised position of the combustion gas discharge outlets and the air intake opening.

4 To ensure adequate accessibility to the appliance and facilitate

maintenance, leave enough space around the boiler.

WARNING

It is forbidden to store inflammable products and materials in the boiler room or close to the boiler, even temporarily.

CAUTION

4 The boiler must be installed in a frost-free

environment.

4 A connection to the mains drainage system for the

discharge of condensate must be available close to the boiler.

5.3.3. Ventilation

(1)

Connection to a chimney

Minimum recommended distance

Do not obstruct the air inlets in the room (even partially).

The compulsory cross section of aeration vents in the premises in which the boiler is installed must comply with the standards current in the country.

CAUTION

In order to avoid damage to the boiler, it is necessary to prevent the contamination of combustion air by chlorine and/or fluoride compounds, which are particularly corrosive. These compounds are present, for example, in aerosol sprays, paints, solvents, cleaning products, washing products, detergents, glues, snow clearing salts, etc. Therefore:

15/03/2016 - 300026081-001-08

4 Do not pull in air evacuated from premises using such

products: hairdressing salons, dry cleaners, industrial premises (solvents), premises containing refrigeration systems (risk of refrigerant leakage), etc.

4 Do not stock such products close to the boilers.

If the boiler and/or peripheral equipment are corroded by such chloride or fluoride compounds, the contractual guarantee cannot be applied.

Forced flue connection

If the discharge of combustion gases and the intake of combustive air are done using a concentric flue, ventilation of the boiler room is only necessary if a mechanical connector is fitted to the gas supply (as per the description in the DTU 61.1 standard).
