Gas Conversion - Riello Residence Condens 35 KIS e Manuel D'installation

ENGLISH
When the contact is closed, the heat request is made by the delive-
ry probe on the basis of the external temperature in order to main-
tain the rated ambient temperature at the DAY level (20 °C). When
the contact opens, it does not stop the heat request but reduces
(parallel shift) the temperature curve to the NIGHT level (16 °C).
This activates the night mode.
Though delivery temperature is automatically calculated by the
boiler, the user may manually override it.
By modifying HEATING on the user interface (IGN, 4a ), the HEA-
TING SET POINT will no longer be available but just a value that
can be set from +5 to -5°C as required.
Modifications to this value do not directly change delivery tempera-
ture but affect the calculation made to automatically determine its
value by modifying the reference temperature of the system (0 =
20°C for DAY level; 16°C for NIGHT level).
14 - ADJUSTMENTS
The boiler has already been factory-adjusted by the manufacturer.
If a new adjustment is required, for example, after extraordinary
maintenance, replacing the gas valve or converting from natural
gas to LPG, proceed as follows.
Maximum and minimum power, maximum heating and slow
start must be adjusted in the indicated sequence by qualified
staff.
- Power the boiler
- Turn the function selector to OFF/RESET (digit "--")
- Unscrew screws A and remove instrument panel B (fig. 4)
- Turn the trimmers in the following sequence and adjust them
until their values correspond with those indicated in the table:
1. Max (1a) (maximum fan rpm)
2. Min (2a) (minimum fan rpm)
3. HTG (3a) (maximum heating fan rpm)
4. IGN (4a) (slow start LA) (3.7=3.700 rpm)
Calibration does not switch on the boiler.
When the trimmers are turned the value expressed in thou-
sands (e.g.. 2.5=2.500 rpm) is indicated on the 2-digit di-
splay).
Slow start LA must be adjusted after calibrating all the other
trimmers.
Gas valve calibration
- Power the boiler.
- Open the gas tap.
- Turn the function selector to OFF/RESET (digit "--") (fig. 10-11).
- Press the combustion analysis button CO (fig. 4).
- Wait for the burner to ignite, "CO" is displayed on the digital di-
splay and the boiler works at maximum heating power. The flue
cleaner function remains active for a maximum of 15 min; if a
delivery temperature of 95°C is reached, the burner switches off.
It is re-ignited when this temperature falls below 75°C.
- Remove the screw G and the plug F and insert the fumes
analysis probe (fig. 37).
- Turn the HTG trimmer clockwise until it reaches the maximum
fan rpm (see table).
- Check the CO
value: if the value does not match that indicated
2
in the table, turn the maximum gas valve adjustment screw (A,
fig. 36).
- Turn the HTG trimmer anti-clockwise until it reaches the mini-
mum fan rpm (see table).
- Check the CO
value: if the value does not match that indicated
2
in the table, turn the minimum gas valve adjustment screw (B,
fig. 36).

- Turn the HTG trimmer to the maximum heating fan rpm (see
table)
- To exit the flue cleaner function, turn the function selector (8, fig.
1)
- Remove the fumes analysis probe and put back the screw and
the plug.
Remount the knobs on the panel. The "combustion analysis" fun-
ction automatically deactivates if the board generates an alarm.
If a fault develops during the combustion analysis phase, perform
the release procedure as follows:
Turn the function selector to
required function.
15 - GAS CONVERSION
It is easy to convert from one gas family to another even after the
boiler has been installed.
This operation must be performed by professionally qualified staff.
The boiler is designed to work with natural gas (G20), as indicated
on the product plate.
The boiler can be converted to propane using the relative kit sup-
plied as an accessory.
To disassemble, proceed as follows (fig. 38):
%
- disconnect the boiler from the power supply and close the gas
tap
- remove the shell and cover of the air distribution box
- release the panel and turn it forwards
- remove the gas pipe (A)
