BoIler maIntenance
prestIge solo 120
ACV recommends that you have your boiler
inspected, and cleaned, if needed, at least
once a year
.
Isolate the appliance before undertaking any work on it, even if you
are simply taking measurements and making adjustments.
- Check that the condensate trap is not clogged, fill it as required
and check for leaks.
- Check that the safety valves are in good working order.
- Bleed the whole system and refill the appliance if needed until it
reaches 1.5 bar.
In the case of repeated fills, contact your
installer. Why do we say this here?
- Check the boiler’s pressure in maximum power mode.
If this value is very different from the original setting, this
deviation may indicate an obstruction in the air intake ducts or
flue gas exhaust pipes, or that the exchanger is clogged.
