INSTRUCTIONS PERTAINING TO THE INSTALLER

3926.772.1 - GB/IEINSTRUCTIONS PERTAINING TO THE USER

This boiler is designed to heat water at a lower than boiling temperature at atmospheric pressure. The boiler

must be connected to a central heating system and/or to a domestic hot water supply system in compliance

with its performances and output power.

The boiler must be installed by a Qualied Service Engineer ensuring that the following operations are carried

out:

a) Careful checking that the boiler is t for operation with the type of gas available. For more details see the

notice on the packaging and the label on the appliance itself.

b) Careful checking that the ue terminal draft is appropriate; that the terminal is not obstructed and that no

other appliance exhaust gases are expelled through the same ue duct, unless the ue is especially desi-

gned to collect the exhaust gas coming from more than one appliance, in conformity with the standards

and regulations in force.

c) Careful checking that, in case the ue has been connected to pre-existing ue ducts, thorough cleaning

has been carried out in that residual combustion products may come off during operation of the boiler and

obstruct the ue duct.

d) To ensure correct operation of the appliance and avoid invalidating the warranty, observe the following

precautions:

1. Hot water circuit:

If the water hardness is greater than 20 °F (1 °F = 10 mg calcium carbonate per litre of water) a

polyphosphate or comparable treatment must be used in response to current regulations.

2. Heating circuit

2.1.New system

Before proceeding with installation of the boiler, the system must be cleaned and ushed out thoroughly

to eliminate residual thread-cutting swarf, solder and solvents if any, using suitable proprietary

products.

To avoid damaging metal, plastic and rubber parts, use only neutral cleaners, i.e. non-acid and non

alkaline. The recommended products for cleaning are:

SENTINEL X300 or X400 and FERNOX heating circuit restore. The use of this product must be strictly

in accordance with the maker’s directions. Finally the system must be dosed with a suitable inhibitor

at 1% system volume.

2.2. Existing system

Before proceeding with installation of the boiler, the system must be cleaned and ushed out to remove

sludge and contaminants, using suitable proprietary products as described in section 2.1.

To avoid damaging metal, plastic and rubber parts, use only neutral cleaners, i.e. non-acid and non-

alkaline such as SENTINEL X100 and FERNOX heating circuit protective.

Remember that the presence of foreign matter in the heating system can adversely affect the operation

of the boiler (e.g. overheating, noisy operation, or failure of the heat exchanger may occur).

Failure to observe the above will render the warranty null and void.

1. INSTRUCTIONS PRIOR TO INSTALLATION

Initial lighting of the boiler must be carried out by a qualied service engineer. Ensure the following operations

are carried out:

a) Compliance of boiler parameters with (electricity, water, gas) supply systems settings.

b) Compliance of installation with the standards and regulations in force.

c) Appropriate connection to the power supply and earthing of the appliance.

Failure to observe the above will render the warranty null and void.

Prior to commissioning remove the protective plastic coating from the unit. Do not use any tools or abrasive

detergents as you may damage the painted surfaces.

IMPORTANT: The instructions contained in this manual relating to the operation of the hot water circuit

are relevant only if the appliance is actually connected to a hot water system.

To correctly light the burner proceed as follows:

1) Provide power supply to the boiler;

2) Open the gas cock;

3) Follow the directions given below regarding the adjustments to be made at the boiler control panel.

3. COMMISSIONING OF THE BOILER

5926.772.1 - GB/IEINSTRUCTIONS PERTAINING TO THE USER

a) Automatic operation. Operation of the boiler is controlled by the timed program as described in point

3-5.1 “Daily timed program for operation of the central heating system”;

b) Manual operation at the maximum temperature set. The boiler comes into operation regardless of

the timed program set. The operating temperature is that set using the key (point 3-3: “Setting

the maximum central heating temperature”);

c) Manual operation at minimum temperature. The operating temperature is that set in point 3-6:

“setting the minimum central heating temperature”.

The manual transition from positions a) and b) to position c) involves shut-down of the burner and

disconnection of the pump after the post-circulation delay interval (the factory setting for this parameter

is 3 minutes).

d) standby. The boiler does not work in central heating mode, although the frost protection function is

still enabled.

(1) Hot water on/off key: Press this key to activate or inhibit this function, which is identied by the

appearance on the display of two black dashes under the symbol.

(4) Reset key. In case of a fault, referred to in point 3-7 “Faults and resetting the boiler”, the boiler

can be restarted by pressing this key for at least two seconds.

If this key is pressed with no fault present, the display will show the message “E153”, and the same

key has to be pressed again (for at least two seconds) to restart the boiler.

(9) Data key. This key can be pressed repeatedly to display the following information:

- Temperature (°C) of the hot water ( );

- outdoor temperature (°C) ( ); only provided with the outdoor temperature sensor probe

connected.

Press either of the keys to return to the main menu.

10 926.772.1 - GB/IEINSTRUCTIONS PERTAINING TO THE USER

To shut down the boiler switch off the electrical supply to the appliance.

Important: Regularly check that the pressure displayed by the pressure gauge is between 1 to 4 bar, with the

boiler not operating.

In case the pressure is lower open the boiler lling tap.

We recommend you open the tap very slowly in order to let off the air.

In case pressure drops occur frequently have the boiler checked by a Qualied Service Engineer.

We recommend you avoid draining the whole system as raw water makeup will lead to harmful limestone

deposits inside the boiler and on the heating elements.

In case the boiler is not operated during wintertime and is therefore exposed to danger of frost we suggest you

add some specic-purpose anti-freeze to the water contained in the system (e.g.: propylene glycole coupled

with corrosion and scaling inhibitors).

The electronic management of the boilers includes a ‘frost protection’ function which operates the burner to

reach a heating ow temperature of 30° C when the system heating ow temperature drops below 5°C.

The frost protection function is enabled if:

* electrical supply to the boiler is on;

* the gas service cock is open;

* the system pressure is as required;

* the boiler is not isolated.

To maintain efcient and safe operation of your boiler have it checked by a Qualied Service Engineer at the

end of every heating season. Careful servicing will ensure economical operation of the system.

Do not clean the outer casing of the appliance with abrasive, aggressive and/or easily ammable cleaners

(i.e.: gasoline, alcohol, and so on). Always isolate the electrical supply to the appliance before cleaning it (see

section 5 Turning off the boiler).

These boilers are produced for natural gas and can be converted to work with LPG (G 31).

Any gas change must be effected by a Qualiﬁed Service Engineer.
