protected against atmospheric agents. The main elements
choices made by
– the atmospheric burner combined with a copper heat

exchanger for heating and a rapid heat exchanger for DHW

– the sealed combustion chamber, with respect to the room

where the boiler is installed

– the command and control microprocessor electronic board

provides efficient management of both heating and hot water
production. It can also be connected to a remote control
with an Open Therm protocol or to room thermostat and/or
external sensor. If connected to an external sensor, the boiler
temperature varies on the basis of the external temperature
according to a selected optimal climatic curve providing

significant energy and economic savings.
Other special features of the
– the anti-freeze function which activates automatically if the

temperature of the water inside the boiler falls below the

threshold of the value set at parameter "PAR 10" and , if there

is an external sensor, if the external temperature falls below

the threshold of the value set at parameter "PAR 11"
– the anti-blocking function of the pump and diverter valve, this

activates automatically every 24 hours if no request for heat

has been made
– the chimney sweep function lasts 15 minutes and makes the

job of the qualified technician easier when measuring the

parameters and combustion efficiency
– screen display of the operating and self-diagnostic

parameters with error code display when the fault occurs.

Before removing an old heat generator from an existing system,
it is recommended that the user:
– puts a descaling additive into the water system
– allows the system to work with the generator active for a few

days

– drains the dirty water from the system and flushes the system

with clean water once or more than once.
If the old generator has already been removed or is not available,
replace it with a pump to circulate water in the system and then
proceed as described above.
Once cleaning operations have been carried out and before
installing the new appliance, it is recommended that a fluid
is added to the water system to protect it from corrosion and
deposits.

temperature of the appliance, calculated and manufactured
in compliance with Standards, current editions, that it is as
straight as possible, air tight, isolated, with no obstructions or
restriction and that it has appropriate condensate collection
and evacuation systems

– the electrical system has been manufactured in compliance

CAUTION

For further information on the type of additive and
usage, please contact the appliance manufacturer.

8.7 Water system treatment

When filling and restoring the system it is good practice to use
water with:
– aspect: clear if possible
– pH: 6÷8
– hardness: < 25°f.
If the water characteristics are different from those indicated, it
is recommended that a safety filter is used on the water delivery
pipe to retain impurities, and a chemical treatment system to
protect against possible deposits and corrosion which could
affect boiler operation.
If the systems are only low temperature systems, it is
recommended that a product is used to prevent the development
of bacteria.
In any case, please refer to and comply with Legislation and
specific Technical Standards in force.

11 COMMISSIONING BOILER CHECKLIST

ü

A suggested method of commissioning the boiler; the actual method can vary according to the boiler make, type and installation. The
boiler must always be installed and commissioned by an approved gas technician. The installer certifies that this Boiler has been
installed to the manufacturer's instructions, has been filled, commissioned and is ready for use.

N° Description

When done

1 Read carefully the instruction manuals supplied with this boiler.

2 BEFORE INSTALLING T HIS BOILER FLUSH OUT THE PIPES UNTIL CLEAN WATER IS ACHIEVED.

Turn off all services to–this boiler - water, gas and power.

3

Install the boiler as shown in the instructions following and connect all services.

Turn on water to fill system, check for leaks regularly and bleed air from all points.

4

Bleed the air from all the pumps in the system, and rotate the impeller shaft.

Check that all radiators valves are open, remove the thermostatic valve heads, fully open all

5

lockshield valves.

Turn ON gas, bleed air out at the isolation valve union. Reseal and check for gas leaks.

6

Turn gas OFF.

Turn electricity on at the power point. At the boiler front panel set the temperature setting to the

7

lowest setting, switch boiler to ON position.
The “Power on” Indicator should light. Turn the boiler off at the front panel.

Turn the room thermostat to the manual ON position set the temperature to a high level so that it

8

does not switch off during the commissioning phase. The thermostat will unusually click and show an
an indicator in the window.

9 Switch the boiler ON at the boiler front panel control.

Boiler should start fan, pump and ignite gas. If it fails first few times this may be just residual air in

10

the gas line. A noisy water pump indicates there is air in the water pipes.

Boiler lights and heats the water. Check gas flame is the correct colour and for gas and water leaks

11

as the system heats up.

Check that heat is going to all radiators through the manual or thermostatic first and return via the

12

lockshield valve. If not STOP fix NOW and any leaks.

Allow the boiler to heat up to the set temperature and switch off. Re-adjust the boiler temperature to

13

a mid temperature point. CAUTION, If this is connected to a floor heating system. The boiler should re
light and increase the water temperature to the new setting.

Check that all radiators are hot all the way up. If the radiator is cold at the top, then there is usually

14

air in the radiator Bleed the radiator. Balance the system so that all. radiators are hot as according to
the radiator installation manual. Adjust the boiler water temperature.

Set the room thermostat to the correct times and temperatures according to the manufacture's

15

instructions.

On completion of the commissioning phase, complete the information sheet at the front of this
manual. Hand over the installation to the owner and demonstrate how the system works plus basic

16

fault resolution and safety procedures. Make sure that this important document is kept in a safe
accessible place.
