4.8 Maintenance
Periodic maintenance is essential to the safety, efficiency and lifetime
of the boiler. The appliance must be systematically controlled at reg-
ular intervals to make sure it works correctly and efficiently and con-
forms to legislative provisions in force.
It allows for the reduction of consumption, polluting emissions and
keeping the product reliable over time.
Before starting maintenance operations:
- Perform the analysis of the combustion products to check the boil-
er operation status then cut the electrical supply by turning off the
system's general switch
- Close the fuel and water taps of the heating and domestic hot wa-
ter system.
After performing the necessary maintenance operations, the
original adjustments must be restored and the combustion
product analysis must be performed to check the correct oper-
ation.
4.9 Adjustments
The

with Methane gas (G20) and is factory set as shown on the rating
plate.
If adjustments have to be redone, for example after extraordinary
maintenance, after the gas valve replacement or after conversion
from methane gas to LPG and vice versa, the following procedures
must be followed.
The maximum heating electrical value adjustment, the mini-
mum and maximum electrical heating, must be carried out in
the sequence indicated and exclusively by the Riello Technical
