Maximum Fan Speed - Riello FAMILY CONDENS 2.5 KIS E Installer And User Manual

FAMILY CONDENS KIS E
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.
4.10 Adjustments
The FAMILY CONDENS KIS 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
until you see "ENERGY FOR LIFE" on the display.
During the parameter modification operations, the

ESCAPE key (Exit). If no confirmation is given within 10 sec-
onds, the value is not stored and the previous one is indicated
again.
Setting the "programming access" password
- The programming of the parameters is accessed by pressing the
key and then pressing the
- PROG appears on the display followed by CODE.
- Press the ENTER key to confirm.
- Enter the adjustment code by rotating the encoder until the neces-
sary value is reached.
- Confirm the adjustment code by pressing the ENTER key.
The programming access password is located inside the command
panel.

Setting the "Combustion analysis" password
The programming of the parameters is accessed by pressing the
key and then pressing the
PROG appears on the display followed by CODE.
Press the ENTER key to confirm.

Calibration stages
The CALIBRATION & SERVICE phases scroll in sequence by turn-
ing the encoder:
01 type of gas (do not modify this parameter)
02 boiler output (insignificant parameter)
03 degree of insulation of the building (only displayed if an external
probe is connected)
10 DHW mode (do not modify this parameter)
45 thermoregulation curve inclination (only displayed if an external
probe is connected)
47 thermoregulation curve inclination 2CH (only displayed if an ex-
ternal probe is connected)
HP maximum fan speed (do not modify this parameter)
LP minimum fan speed (do not modify this parameter)
SP ignition speed (do not modify this parameter)
HH boiler at maximum output
LL boiler at minimum output
23 maximum heating electrical value adjustment
24 minimum heating electrical value adjustment (do not modify this
parameter)
Parameters 2 - 10 - HP - LP - SP - 23 - 24 must only be modi-
fied by professionally qualified personnel, and only if absolutely
necessary.
The manufacturer declines all responsibility if the parameters
are incorrectly set.

MAXIMUM FAN SPEED (P. HP)
- Select parameter HP.
- Press the ENTER key to be able to modify the parameter value.
The maximum fan speed is linked to the type of gas and the boiler
output - table 1.
- Turn the encoder until the desired value is reached
- Confirm the new value by pressing ENTER.
Modify this parameter only when absolutely necessary.
The value is expressed on the display in rpm/100 (e.g. 3.600 = 36).
