13 SERVICING INSTRUCTIONS
13.1 General
To ensure the continued safe and efficient operation of the
boiler, it is recommended that it is checked and serviced at
regular intervals. Maintenance is mandatory once a year.
If the application works in heavy duty conditions it may require
a higher
frequency of maintenance than once a year (*), in either
case refer to the yearly check list (paragraph 13.2.1).
(*) Higher frequency of maintenance is necessary under
conditions below:
- if a problem is identified during a yearly check
- Efficiency reduction, a fault, malfunction or breakage.
- Gas with high sulphur rates, still within the acceptable range
but close to the limits declared: a maximum annual peak over
a short period of time of 150 mg/m3 and an annual average
of 30 mg/m3.
- Water Hardness, pH and Chlorine concentration still inside
the acceptable range but close the limits declared in
manufacturer’s instructions
- Air for combustion drawn from an area with dust, debris or
airborne contaminants
- If work or maintenance is performed on structures located
near the flue and/or air ducts and their accessories
- Frequent ON-OFF cycles
- Boiler oversized or undersized compared to the actual needs
of the building, that leads to frequent ON-OFF cycles or boiler
operation much longer than the usual annual average.
It is essential that any worn or failed component be replaced
only with genuine RIELLO spare parts.
Use of non-genuine spare parts will void your warranty and may
pose a potential safety hazard.
The following instructions apply to the appliance and its
controls, however, it is important to pay attention also to the
maintenance of the central heating and the domestic hot water
systems and all system components.

Maintenance
9
WARNING:
In the boiler there are gas, flue
and electrical
hazards so maintenance and REGULAR SERVICE
must be
performed by a qualified service agency. Failure to do so
may result in substantial property damage, severe injury or
death.
9
WARNING:
Regular service and maintenance are mandatory
to ensure safety for the users and maximum operating
efficiency for the life of the appliance. Furthermore, it allows
for the reduction of energy consumption and emissions;
keeping the product reliable over time.
The frequency of servicing will depend upon the particular
installation conditions, but, in general, at least once per year
must be done.
The State Boiler Laws require that any service work is carried
out by a competent person such as a qualified technician, an
approved service agent, or other suitably qualified personnel.
Tools for maintenance operations:
- A dynamometer device
- A combustion analyzer
- A vacuum cleaner
- White vinegar in a spray bottle
- A nylon hand brush
- A nylon mechanic brush with a portative drill
- Water
- A gas manometer

After carrying out the maintenance operations a
combustion analysis needs to be carried out to make sure the
boiler is operating correctly.
9
WARNING:
After the replacement of the electronic board
or the maintenance of the flame sensor or the burner, the
combustion analysis, it may be necessary to proceed with
combustion analysis procedure as described in section “11.21
Note:
When the flame sensor is replaced, slight variations in the
combustion parameters can occur. This data will return to the
nominal values after a few hours of operation.
Yearly maintenance program
1
Check that area is free from combustible materials,
gasoline and other flammable vapors and liquids.
2
Visually check the top of the vent for soot. Call service
person to clean. Some sediment at bottom of vent is
normal.
3
Clean the screens in the vent terminal
4
