INSTRUCTIONS FOR
MAINTENANCE AND INITIAL
CHECK
3.1 GENERAL RECOMMENDATIONS
Operators who install and service the ap-
pliance must wear the personal protec-
tive equipment (PPE) required by appli-
cable law.
The list of possible PPE is not complete as
they are indicated by the employer.
Before carrying out any maintenance work,
make sure that:
– you have disconnected the power to the
appliance;
– you have closed the gas cock;
– you have discharged the pressure from
the system and domestic hot water circuit.
Risk of material damage after using sprays and
liquids to search for leaks
Leak sprays and liquids clog the reference hole P. Ref.
(Fig. 41) of the gas valve, damaging it irreparably.
During installation and maintenance, do not use spray
or liquids in the upper area of the gas valve (side referring
to the electric connections).
Supply of spare parts
The device's warranty shall be rendered null and void if
unapproved or unsuitable parts are used for mainte-
nance or repairs. These will also compromise the prod-
uct's compliance, and the said product may no longer be
valid and fail to meet the current regulations. in regard
to the above, only use original Immergas spare parts
when replacing components.
If additional documentation needs to be consulted for
extraordinary maintenance, contact the Authorised Af-
ter-Sales Service.

INITIAL CHECK

To commission the boiler:
- ensure that the type of gas used corresponds to the boiler set-
tings (the type of gas appears on the display on first electrical
power supply, on the data nameplate or by checking the relative
parameter "G");
- check connection to a 230V-50Hz power mains, correct L-N
polarity and the earthing connection;
- make sure the central heating system is filled with water and
that the boiler manometer indicates a pressure of 1÷1.2 bar;
- switch the boiler on and ensure correct ignition;
- check the proper calibration of the number of fan revolutions;
- check the CO2 flow rate in the flue:
• maximum
• intermediate
• minimum
- the values comply with the relevant tables (Par. 3.3);
- check activation of the safety device in the event of no gas, as
well as the relative activation time;
- check activation of the main switch located upstream of the
boiler;
- check that the intake and/or exhaust terminals are not blocked;
- ensure activation of all adjustment devices;
- seal the gas flow regulation devices (if the settings are changed);
- ensure production of domestic hot water;
- check the tightness of the hydraulic circuits;
- check ventilation and/or aeration of the installation room
where provided.
Even if just one single safety check pro-
vides a negative result, do not commis-
sion the system.
