5.23 Combustion Control Parameters

Even if the parameters regarding the new ACC combustion control system
(active combustion control) are preset in the factory, it might be necessary
to programme them, this is in the case where both electronic boards (AKM
and REC10 MASTER) need to be replaced at the same time.
Access the technical parameters as explained in the section" Accessing
the technical parameters" entering the SERVICE password. Select
COMBUSTION CONTROL with the "UP" and "DOWN" keys , confi rming
the selection.

b
If after maintenance work on the elements of the combustion unit
(Repositioning the detector electrode or else replacing/cleaning the
primary heat exchanger, condensate siphon, fan, burner, fl ue gases
conveyor, gas valve, gas valve diaphragm), the boiler generates one
or more alarms regarding combustion faults, we recommend setting
the main system switch to off for at least 5 minutes in these cases
we recommend setting the main system switch to off for at least 5
minutes.

5.24 Maintenance and cleaning

Periodic maintenance is an "obligation" pursuant to Pres. Decree of 13th
April 2013 no. 74 and is essential to the safety, effi ciency and duration of
the boiler.
It allows for the reduction of consumption, polluting emissions and keeping
the product reliable over time.
Before starting maintenance operations:
- Close the fuel and water taps of the heating and domestic hot water
system.
To ensure product characteristics and effi ciency remain intact and to
comply with prescriptions of current regulations, it is necessary to render
the appliance to systematic checks at regular intervals. When carrying out
maintenance work, observe the instructions given in the "WARNINGS AND
SAFETY" chapter.
This normally means the following tasks.
- removing any oxidation from the burner
- removing any scale from the heat exchangers.
- checking electrodes.
- checking and cleaning the drainage pipes;
- checking the external appearance of the boiler
- checking the ignition, switch-off and operation of the appliance, in both
domestic water mode and heating mode
- checking the seal on the couplings, gas and water and condensate
connecting pipes
- checking the gas consumption at maximum and minimum output;
- checking the position of the ignition electrode
- checking the position of the detector electrode/ionisation probe (see
specific paragraph)
- checking the gas failure safety device.
b
After carrying out the maintenance operations the analysis of the
combustion products needs to be carried out to make sure it is
operating correctly.
b
If, after replacing the electronic board or having carried out
maintenance on the detector electrode or the burner, the analysis of
the combustion products returns values outside tolerances, it might
necessary to change the COMBUSTION OFFSET parameter as
described in the section "Combustion Control Parameters".
Note: When replacing the electrode there could be slight variations
of the combustion parameters that fall within nominal values after a
few hours of operation.
b
Do not clean the appliance or its parts with infl ammable substances
(e.g. petrol, alcohol, etc.).
b
Do not clean panels, painted parts and plastic parts with paint thinner.
b
Panel cleaning must be carried out only with soapy water.
