(D) Definitive
(T) Temporary. In this operating status, the boiler attempts to re-
solve the fault situation autonomously
(°) See the NOTE on the previous page
(**) If these two errors arise, check the pressure shown on the hy-
drometer.
If the pressure is insufficient (< 0.4 bar - red field), perform
the filling operations described in the “Filling and draining the
systems” chapter.
If the system pressure is sufficient (> 0.6 bar - light blue field),
the fault is due to a lack of circulating water. Contact the Tech-
nical Assistance Centre.

Temporary switch-off
In the event of a temporary absence, weekends, short journeys and
so on: press
. The display will visualise the words “ENERGY FOR
LIFE” and the anti-freeze icon.
In this way (leaving the electricity and fuel supplies enabled),
the boiler is protected by the following systems:
- Antifreeze: when the boiler water temperature falls to 7°C, the cir-
culator is activated and, if necessary, also the burner (at the mini-
mum output) to bring the water temperature back within the safety
values (35°C). The
icon will flash on the display, indicating that
the anti-freeze function is active.
- Circulator anti-locking: an operation cycle is activated every 24 h.
4.8
Switching off for lengthy periods
The long term non use of the FAMILY CONDENS IS E boiler causes
the execution of the following operations:
- press
. The wording “ENERGY FOR LIFE” and the antifreeze
icon are displayed
- set the system's main switch to "off"
- turn off the fuel and water taps of the heating and domestic hot
water system.
In this case, the anti-freeze and anti-blocking systems are de-
activated.
Drain the heating and domestic water system if there is any risk
of freezing.
4.9
Maintenance
The appliance must be systematically controlled at regular intervals
to make sure it works correctly and efficiently and conforms to
legislative provisions in force.
The frequency of controls depends on the conditions of installation
and usage, it being anyhow necessary to have a complete check
carried out by authorized personnel from the Riello Technical
Assistance Service every year.
- Check and compare the boiler’s performance with the relative
specifications. Any cause of visible deterioration must be
immediately identified and eliminated.
- Closely inspect the boiler for signs of damages or deterioration,
particularly with the drainage and aspiration system and electrical
apparatus.
- Check and adjust – where necessary – all the burner’s parameters.
- Check and adjust – where necessary – the system’s pressure.
-
Analyze combustion. Compare results with the product’s
specification.
Any loss in performance must be identified and corrected by finding
and eliminating the cause.
- Make sure the main heat exchanger is clean and free of any
residuals or obstruction; if necessary clean it.
- Check and clean – where necessary – the condensation tray to
make sure it works properly.
IMPORTANT: always switch off the power to the appliance and
close the gas by the gas cock on the boiler before carrying out any
maintenance and cleaning jobs on the boiler.
Do not clean the appliance or any latter part with flammable
substances (e.g. petrol, alcohol, etc.).
Do not clean panelling, enamelled and plastic parts with paint
solvents.
Panels must be cleaned with ordinary soap and water only.
The flame side of the burner is made of state-of-the-art material.
Being fragile:
- be particularly careful when handling, mounting or dismantling
the burner and adjacent components (e.g. electrodes, insulation
panelling etc.)
- avoid direct contact with any cleaning appliance (e.g. brushes,
aspirators, blowers, etc.).
This component does not need any maintenance, please do not
remove it from its housing, save where the O-ring may have to be
replaced.
The manufacturer declines all responsibility in cases of damages due
to failing to observe the above.
4.10
Adjustments
The FAMILY CONDENS IS E boiler is provided for operation with
Methane gas (G20) or LPG (G31) 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
Assistance Service.
- Set the system's main switch to "off"
- Unscrew the fixing screw of the couplings cover, then remove it
from its seat by pulling toward you
- Undo the fixing screws of the shell
- Move the housing base forwards and then upwards to unhook it
from the frame
- Lift the control panel and successively turn it forward
- Loosen the screw of the pressure test point downstream from the
gas valve by roughly two turns, then connect the pressure gauge.
The CALIBRATION & SERVICE operations must be performed
with the boiler in the off position.
To do this, press the
key until you see "ENERGY FOR LIFE"
on the display.
During the parameter modification operations, the
key
acts as an ENTER key (Confirm), while the key acts as an
ESCAPE key (Exit).
If no confirmation is given within 10 seconds, the value is not
stored and the previous one is indicated again.
