3.2.6.3. Ø 80 mm air/flue gas split duct system
Installation types C43 – C53 – C83
Minimum permissible length of air intake pipe is 1 meter.
Minimum permissible length of flue gas discharge pipe is 1 meter.
Maximum permissible length of air intake/flue gas discharge pipes is 120 meters (combined length of air intake and flue gas discharge
pipe length).
For each additional 1 meter of straight pipe maximum permissible length is to be reduced by 1 meter.
For each additional 90° elbow, maximum permissible length is to be reduced by 1.5 meter.
For each additional 45° elbow, maximum permissible length is to be reduced by 1 meter.
The condensate trap reduces maximum permissible length by 1.5 meters.
The roof terminal reduces maximum permissible length by 1.5 meters.
The wall terminal reduces maximum permissible length by 1 meter.
The above data are referred to air intake/flue gas discharge system, implemented with original, rigid and smooth ducts,
delivered by the manufacturer.

3.2.7. Testing combustion efficiency
3.2.7.1. “Chimney sweep” function
The boiler is equipped with “chimney sweep” function, to be used when testing combustion efficiency, and in order to adjust the burner.
When no. 9 selector (pic. 1) is positioned to WINTER, and ambient thermostat (if available) to ON, while the boiler is operating, press SPA
button (pic. 13) for at least 10 seconds; the boiler turns off and resumes the ignition sequence again to the maximum heat output corre-
sponding to maxR trimmer setting (pic. 13), which allows for adjustment of maximum CH output.
“Chimney sweep” function operates for 15 minutes. In order to exit the “chimney sweep” function, set no. 9 selector to any position
other than WINTER.
