Chimney sweep function

To carry out the verification of combustion
in the boiler, turn the selector and stop on
the position ( ) until the green/orange bi-
colour led starts to blink.
From that moment the boiler will start func-
tioning in heating mode at the maximum
power, with switching off at 80°C and
restarting at 70°C.
Before activating the chimney sweep func-
tion make sure that the radiator valves or
eventual zone valves are open.
The test may be carried out also during hot
water functioning. To test, simply run hot
water from one or more faucets after turn-
ing on the chimney sweep function. Even in
this condition the boiler functions at the
maximum temperature always with the pri-
mary controlled between 80°C and 70°C.
During the entire duration of the testing the
hot water taps must remain open. After
verifying the combustion the boiler should
be switched off by placing the selector on
the (OFF) position; then return the selector
to the desired function.
ATTENTION: After about 15 minutes the
chimney sweep function automatically
deactivates.
