The boiler features a flue cleaning function which must be used to measure combustion efficiency during operation and to adjust the burner.
To enable the flue cleaning function, press the “reset” key (
C
, fig. 1) and keep it pressed for 5 seconds.
When the flue cleaning function is activated with the boiler in WINTER mode, and ambient thermostat ON (if installed), the boiler performs the
ignition sequence and then operates at a fixed power output which corresponds to the one set through parameter
P95
.
The flue cleaning symbol steady on (
12
, fig. 1), the flame symbol on (
14
, fig. 1) - if burner is on - and gas valve modulation coil input
current value indicate that the flue cleaning function is active.
The keys active in this function are: “reset” (
C
, fig. 1) and “DHW +/-” (
A
, fig. 1).
The flue cleaning function lasts 15 minutes.
To quit flue cleaning function, press “reset” and you will go back to the standard operating mode.
Use “DHW +/-” buttons (
A
, fig. 1) to change
current input to gas valve modulation
coil through the available range, from
a minimum value (parameter
P96
) to
a maximum value (parameter
P95
)
automatically set according to boiler type.
The display shows the “wrench” symbol (
13
,
fig. 1) to warn user that parameter is being
modified, the “flue cleaning” symbol (
12
,
fig. 1), the gas valve modulation coil input
current value and the flame on symbol (
14
,
fig. 1) if burner is on.
Air intake CTFS / RTFS 32
Minimum permissible length of air intake pipe is 1 meter.
Each wide radius 90° air-intake elbow (R=D) is equivalent to a 0.8 metre long straight
pipe section.
Each narrow radius 90° air-intake elbow (R=D) is equivalent to a 1.7 metre long
straight pipe section.
Every air intake pipe length of one metre is equivalent to a 0.6 metre long straight
pipe section.
Every split pipe chimney at intake is equivalent to a 4.2 metre long straight pipe
section.
Air intake pipe flow resistance shall not be considered.

Flue gas vent CTFS / RTFS 32
Each wide radius 90° elbow (R=D) in flue gas vent equals a 1.4 m long straight pipe section.
Each narrow radius 90° elbow (R<D) in flue gas vent equals a 2.8 m long straight pipe section.
Every flue gas vent pipe length of one metre is equivalent to a 1.0 metre long straight pipe section.
Every split pipe chimney at glue gas vent is equivalent to a 5.9 metre long straight pipe section.
