Instructions prior to installation

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) 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 thus engendering dangerous situations.

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.

Commissioning of the boiler

To correctly light the burner proceed as follows:

1) provide power supply to the boiler;

2) open the gas cock;

3) turn the selector switch (1) to set the boiler on summertime ( ) or

wintertime ( ) operation;

4) turn the central heating (5) and domestic hot water (6) adjusting

controls in order to light the main burner.

To increase temperature values turn the control clockwise and

anticlockwise to decrease it.

When on summertime operation ( ) the main burner and the pump

will start running only when there is a call for hot water.

Figure 2

Warning: During initial lighting, until the air contained in the gas pipes

is not released, the burner may fail to light immediately and that may

cause a ‘blockage’ of the boiler. In this case we recommend you repeat

the ignition procedure until gas is delivered to the burner, setting selector

(1) to ( ) for at least 1 second (see also figure 4).

Room temperature adjustment

The system must be equipped with a room thermostat (see the relevant

regulations) to control the temperature in the rooms.

In case there is no room thermostat, during initial lighting it will be

possible to control the room temperature by turning control (5).

To increase temperature values turn the control clockwise and

anticlockwise to decrease it. Electronic modulation of the flame will

enable the boiler to reach the set temperature by adapting the gas supply

to the burner to the actual heat exchange demand.

DHW temperature adjustment

The gas valve is provided with an electronic flame-

modulating function, which operates depending on

the DHW temperature adjusting control (6) settings

and on the quantity of water drawn from the taps.

This electronic device allows to keep the water

coming out of the boiler at a constant temperature

also when small quantities of water are drawn.

To ensure energy saving and economical manage-

ment of your boiler, we recommend you place the

switch adjusting the hot water temperature on

“comfort”

(see figure 2). In wintertime it will be

necessary to increase the DHW temperature

according to needs.

Filling the boiler

Important: Regularly check that the pressure displayed by the pressure

gauge (7) is 0.5 to 1 bar, with boiler not operating. In case of overpressure,

open the boiler drain valve.

In case the pressure is lower open the boiler filling tap (figure 3).

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.

The boiler is supplied with a hydraulic differential pressure sensor, which

blocks the boiler in case water is lacking or the pump is blocked.

Turning off the boiler

To turn off the boiler turn the selector switch (1) on (0); you will thus

isolate the electrical supply to the boiler.

Prolonged standstill of the system.

Frost protection (central heating system)

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).

Gas change

These boilers produced for natural gas can be converted to work with

LPG.

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

General information

Warning: When the selector switch (1) is

set on Wintertime operation ( ) it may

be necessary to wait some minutes at each

intervention of the central heating tempera-

ture adjusting control (5). To relight the main

burner immediately place the selector switch

(1) on (0) and then again on ( ). No

waiting is needed when the boiler is in the

DHW mode on models with this option.

The following remarks and instructions are addressed to Service

Engineers to help them carry out a faultless installation. Instructions

regarding lighting and operation of the boiler are contained in the

‘Instructions pertaining to the user’ section.

Note that installation, maintenance and operation of the domestic gas

appliances must be performed exclusively by qualified personnel in com-

pliance with current standards.

Please note the following:

*This boiler can be connected to any type of double- or single feeding

pipe convector plates, radiators, thermoconvectors. Design the system

sections as usual though taking into account the available output /

pump head performances, as shown on page 23.

*Do not leave any packaging components (plastic bags, polystyrene,

etc.) within children’s reach as they are a potential source of danger.

*Initial lighting of the boiler must be effected by a Qualified Service

Engineer.

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

Instructions prior to installation

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, on models withis option, to a domestic hot water supply

system in compliance with its performances and output power.

Before connecting the boiler have the following operations effected:

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 gase 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 thus engendering dangerous

situations.

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) install 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.

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.

To avoid damaging metal, plastic and rubber parts, use only neutral

cleaners, i.e. non-acid and non-alkaline (e.g. SENTINEL X400 and

X100), 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)

The template to fix the boiler on

the wall

Decide upon the boiler location, then tape the template on the wall.

Connect the pipework to the gas and water inlets prearranged on the

template lower bar.

We suggest you fit two G3/4 stop cocks (available on demand) on the

central heating system flow and return pipework; the cocks will allow to

carry out important operations on the system without draining it

completely.

If you are either installing the boiler on a pre-existent system or

substituting it, we suggest you also fit settling tanks on the system return

pipework and under the boiler to collect the deposits and scaling which

may remain and be circulated in the system after the purge.

When the boiler is fixed on the template connect the flue and air ducts

(fittings supplied by the manufacturer) according to the instructions given

in the following sections.
