Maintenance (inspection, overhaul) is essential for the safety, proper

operation and life of the boiler.

It is carried out in accordance with the provisions of the rules in force.

It is recommended that periodic flue gas (combustion) analysis be

performed to monitor the efficiency and emissions of pollutants in

accordance with applicable regulations.

Before starting maintenance:

- electrically disconnect the boiler and set the external bipolar switch to

the OFF position - close the gas tap and the water taps of the

heating and plumbing installations;

At the end, the initial settings are played back (resumed).

General Notes

It is advisable to carry out the following checks (checks) on the

appliance at least once a year:

1. Checking the insulation gaskets (support) on the water side with the

possible replacement of the gaskets and restoring the tightness.

2. Checking the insulation gaskets on the gas side if necessary

replacement of gaskets and restoration of tightness.

3. Eye-check of the overall condition of the appliance.

4. As a result of the check in point 3, any disassembly and

cleaning the combustion chamber

5. Cleaning the main heat exchanger.

6. Checking the operation of the heating safety systems:

- temperature limit safety.

7. Checking the operation of the safety systems on the side of

gas:

- safety without gas or flame (ionization).

8. Control of domestic water production efficiency (bit and temperature

verification).

9. General control of the operation of the appliance.

10. Remove the oxide from the ionization electrode with a piece of

rough cloth (DO NOT use sandpaper!)

The presence of oxide on the heat exchanger does not affect the

performance of the boiler. If you feel the need to clean the heat

exchanger, follow the steps below.

Cleaning the primary exchanger

Connect to the primary heat exchanger by removing the burner - see

Fig. The heat exchanger is cleaned with a non-metallic brush and a

vacuum cleaner.

DO NOT use acidic liquids or

detergent.

Careful!

It is mandatory to replace the

gasket (see figure) each time

the burner is removed.

Also clean the flue (located in

front of the heat exchanger)

before mounting.

When removing the siphon, use

a suitable container to collect

condensate that may leak from

the boiler.

Soda cleaning

The siphon is reached by avoiding the condensate at the bottom.

Washing can be done with water and detergent.

Refit the condenser tank.

NB: In case of prolonged non-use of the rat water, the siphon

MUST BE FILLED BEFORE A NEW START.

LACK OF WATER IN THE SIPHON IS DANGEROUS AND CAN

CAUSE SMOKE TO COME OUT INTO THE ATMOSPHERE.

Function test After

carrying out maintenance and inspection work, refill the heating circuit

at a pressure of approx. 1.0 bar and ventilate the system. Refill the

domestic water system as well.

- Switch on the appliance.

- If necessary, ventilate the heating system again.

- Check the settings and proper operation of all control, adjustment and

control devices.

- Check the insulation (tightness) and proper operation of the flue gas /

combustion supply system required for combustion (combu rent).

Installation emptying operations

The heating system must be emptied as follows:

- switch off (switch off) the boiler and set the external bipolar switch to

the OFF position and close the gas valve;

- loosen (open) the automatic exhaust valve;

- open the drain valve of the installation by squeezing the water that

drains into a water tank;

- evacuate from the lowest points of the installation (where they are

provided).

If it is intended to keep the system switched off in areas where the

ambient temperature may drop below 0 ° C during the winter, it is

advisable to add antifreeze liquid to the water in the heating system to

avoid repeated drainage; If you use such a liquid, please contact the

ARISTON Service Center for any further information on the most

suitable products to use.

Periodically check the pH of the water-antifreeze mixture (between 7

and 8) in the boiler circuit and replace the mixture when the measured

value is less than the limit prescribed by the manufacturer.

DO NOT MIX DIFFERENT TYPES OF ANTIFREEZE.

The manufacturer is not responsible for any damage caused to the

water or system and caused by the use of unsuitable antifreeze or

additives.

Draining the sanitary installation

Whenever there is a danger of frost, the sanitary installation must be

emptied as follows:

- Turn off the water tap,

- open all hot and cold water taps,

- empty from the bottom points (where provided).

CAREFUL

Empty components that may contain hot water by activating any drain

valves before handling them.

Carry out the unclogging (unclogging) of the limescale of the components

in accordance with the specifications in the safety data sheet of the

product used, ventilating the environment, using protective equipment,

avoiding mixing different products, protecting the appliance and the

surrounding objects.

Seal the openings used to read the gas pressure or gas settings.

Make sure the nozzle is compatible with the supply gas.

If you smell or see smoke coming out of the appliance or smell strong

gas, turn off the power supply, turn off the gas tap, open the windows,

and inform your technician.
