Also in this case, function conclusion DOES NOT provide values storing.
Note
To calibrate only maximum heating, it is possible to remove the jumper JP2
(to store the maximum) and then get out from the function, without storing the
minimum, setting the mode selector to
the boiler.
After each intervention on the adjustment element of the gas valve, seal
it with sealing varnish.
When adjustment is complete:
- restore set temperature with the ambient thermostat to the desired temperature
- set the heating water temperature selector to the desired position
- close the instrument panel
- pull the shell back in place.
4.6 Gas conversion operations
Conversion from a family gas to other family gas can be performed easily also
when the boiler is installed.
The boiler is designed to operate with methane gas (G20) according to the
product label.
It is possible to convert the boilers from one gas type to another by using the
appropriate kit supplied upon request:
- Methane conversion kit
- LPG conversion kit
For disassembly refer to instructions below:
- remove power supply from the boiler and close the gas tap
- remove in sequence: shell, lower housing and combustion chamber
- disconnect the spark plug cable connection
- slide off the lower cable grommet from the seat of the air distribution box
- remove the burner fixing screws and remove the latter with the spark plug
attached and corresponding cables
- using a socket or fork spanner, remove the nozzles and the washers and
replace them with the ones in the kit (fig. 21).
Use and assemble the washers contained in the kit also in case of
manifolds without washers.
- reinsert the burner in the combustion chamber and tighten the screws fixing
it to the gas manifold
- refit the combustion chamber cover and the lower housing
- restore connection of the spark plug cable
- overturn the control instrument panel towards the boiler front part
- open the card cover
- on the control card (fig. 19):
- if the conversion is from methane gas to LPG, insert the jumper in position
JP3
- if the conversion is from LPG to methane gas, remove the jumper from
position JP3
- reposition the components previously removed
- restore voltage to the boiler and reopen the gas tap (with boiler in operation,
check correct seal of the gas feeding circuit connections).
Conversion must be carried out by qualified personnel.
After conversion, adjust the boiler again following the indications
in specific section and apply the new identification label contained
in the kit.
5 MAINTENANCE
To ensure product characteristics and efficiency remain intact and to comply
with prescriptions of current regulations, it is necessary to render the appli-
ance to systematic checks at regular intervals.
Control frequency depends on the installation and use conditions, but it is
therefore necessary an annual check-up by the authorised personnel from
the Technical Assistance Service.
Turn off the appliance to carry out the maintenance of the structure near
the flue exhaust connections or devices, and their accessories. Once the
interventions are finished a qualified technician must check that the pipes
and the devices work correctly.
IMPORTANT: before carrying out any cleaning or maintenance operation of the
appliance, use the appliance and system switch to interrupt power supply and
close the gas supply turning the tap placed on the boiler.

Do not clean the appliance or its parts with inflammable substances (e.g. petrol,
alcohol, etc.).
Do not clean panels, painted parts and plastic parts with paint thinner.
Panel cleaning must be carried out only with soapy water.
5.1 Check the combustion parameters
To carry out the combustion analysis, proceed as follows:
- open the hot water tap to its maximum output
- set the mode selector to summer "
temperature selector to the maximum value (fig. 22).
- Insert the flue gas sampling connector in the straight section of pipe after the
hood outlet.
The hole for inserting the gas analysis probe must be made in the straight section
of pipe after the hood outlet, compliance with applicable legislation (fig. 23).
Insert the flue gas analysis probe completely.
- Power the boiler
The appliance works at maximum output and it is possible to check combustion.
After analysis is complete:
- close the hot water tap
- remove the gas analyser probe and close the combustion analysis connector.
USER
1A GENERAL wARNINGS
The instruction manual is an integral part of the product and it must therefore be
kept carefully and must accompany the appliance; if the manual is lost or dam-
aged, another copy must be requested from the Technical Assistance Service.
Boiler installation and any other assistance and maintenance operation
must be carried out by qualified personnel according to indications of cur-
rent local regulations.
For installation, it is advisable to contact specialised personnel.
The boiler must only be used for the application foreseen by the manu-
facturer. The manufacturer shall not be liable for any damage to persons,
animals or property due to errors in installation, calibration, maintenance
or due to improper use.
The safety and automatic adjustment devices must not be modified, during
the system life cycle, by the manufacturer or supplier.
This appliance produces hot water, therefore it must be connected to a
heating system and/or a domestic hot water mains, compatible with its
performance and output.
In case of water leakage, close the water supply and contact the Technical
Assistance Service immediately.
In case of absence for long periods time, close the gas supply and switch
off the electrical supply main switch. In case of risk of frost, empty the
boiler.
From time to time check that the operating pressure of the hydraulic system
does not decrease under 1 bar.
In case of failure and/or malfunctioning, deactivate the appliance, and do
not try to repair or intervene directly on it.
Appliance maintenance must be carried out at least once a year: pro-
gram it with the Technical Assistance Service will avoid wasting time and
money.
Boiler use requires to strictly observe some basic safety rules:
Do not use the appliance in any manner other than its intended purpose.
It is dangerous to touch the appliance with wet or damp body parts and/or
in bare feet.
Under no circumstances cover the intake grids, dissipation grids and ventila-
tion vents in the installation room with cloths, paper or any other material.
Do not activate electrical switches, telephone or any other object that causes
sparks if there is a smell of gas. Ventilate the room by opening doors and
windows and close the gas central tap.
Do not place anything in the boiler.
Do not perform any cleaning operation if the appliance is not disconnected
from the main power supply.
Do not cover or reduce ventilation opening of the room where the generator
