Dear Customer,

We are sure your new boiler will comply with all your requirements.

Purchasing one of our products satisfies your expectations: good func­tioning, simplicity and ease of use.

Do not dispose of this booklet without reading it: you can find here some
very useful information, which will help you to run your boiler correctly
and efficiently

.

Do not leave any parts of the packaging (plastic bags, polystyrene, etc.) within children’s reach as
they are a potential source of danger.

The boilers bear the CE mark in compliance with the basic requirements as laid down
in the following Directives:

- Gas Directive 90/396/CEE

- Performance Directive 92/42/CEE

- Electromagnetic Compatibility Directive 89/336/CEE

- Low Voltage Directive 73/23/CEE

2. Instructions prior to
commissioning

Initial lighting of the boiler must be carried out by a licensed technician. 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 laws and regulations in force.
c) appropriate connection to the power supply and grounding of the appliance.
Failure to observe the above will render the guarantee 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 spoil the painted surfaces.

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 to a domestic hot water supply system
in compliance with its performances and output power.
Have the boiler installed by a Qualified Service Engineer and ensure the following operations are
accomplished:

a) careful checking that the boiler is fit 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 flue terminal draft is appropriate; that the terminal is not obstructed and

that no other appliance exhaust gases are expelled through the same flue duct, unless the flue is
especially designed to collect the exhaust gas coming from more than one appliance, in conformity
with the laws and regulations in force.

c) careful checking that, in case the flue has been connected to pre-existing flue ducts, thorough

cleaning has been carried out in that residual combustion products may come off during operation
of the boiler and obstruct the flue duct.

d) to ensure correct operation of the appliance and avoid invalidating the guarantee, 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 system responding to current regulations.

2. Heating circuit

2.1. new system
Before proceeding with installation of the boiler, the system must be cleaned and flushed

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. To use this product proceeding

strictly in accordance with the maker’s directions.

2.2. existing system

Before proceeding with installation of the boiler, the system must be cleaned and flushed

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. To use
this product proceeding strictly in accordance with the maker’s directions.

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

operation of the boiler (e.g. overheating and noisy operation of the heat exchanger).

Failure to observe the above will render the guarantee null and void

.

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”);

To maintain efficient and safe operation of your boiler have it checked by a Qualified Service En­gineer at the end of every operating period. Careful servicing will ensure economical operation of
the system.
Do not clean the outer casing of the appliance with abrasive, aggressive and/or easily flammable
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 produced for natural gas can be converted to work with LPG.
Any gas change be effected by a Qualified Service Engineer.

7. Servicing instructions
and gas change

To shut down the boiler switch off the electrical supply to the appliance.5. Turning off the boiler

Important: Regularly check that the pressure displayed by the pressure gauge is 1 to 1.5 bar, with

boiler not operating.
In case the pressure is lower open the boiler filling 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 Qualified Service Engineer.

4. Filling the boiler

6. Prolonged standstill of the
system. Frost protection

We recommend you avoid draining the whole system as water replacements engender purposeless
and 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 specific-purpose anti-freeze to the water contained in the system (e.g.: propy­lene glycole coupled with corrosion and scaling inhibitors).
The electronic management of boilers includes a ‘frost protection’ function which operates the bur­ner to reach a heating flow temperature of 30° C when the system heating flow 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 blocked.
