Notes; Emptying Operations - Ariston HS PREMIUM Technical Instructions

Machine Translated by Google
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.
