CF model smoke evacuation fault
This test will lock the boiler in case there is a fault with the evacuation
of exhaust gases. Locking of the appliance is temporary and is
indicated by error code 6 01.
After 12 minutes the boiler will start its ignition procedure; if the
conditions return to normal, the boiler restarts normally, otherwise
it locks and the cycle is repeated.
Important
In the event of incorrect operation or repeated problems,
switch o the electricity by setting the external switch to
the "OFF" position, close the gas tap and contact the After-
Sales department or a professional boiler technician to
check the cause of the malfunction and to x the exhaust
gas outlet fault. When maintenance work is carried out on
the appliance, only use genuine spare parts and follow
the corresponding instructions carefully. This appliance
should never be disconnected, as this could endanger the
user.
Anti-frost Device.
The anti-frost function acts on the central heating ow temperature
probe, independently from other settings, when the electrical sup-
ply is turned on. If the primary circuit temperature falls below 8°C
the pump will run for 2 minutes.
After the two minutes of circulation (xed) the boiler will check the
following:
a - if the central heating ow temperature is > 8°C, the pump stops;
b - if the central heating ow temperature is between 4 and 8°C, the
pump will run for another two minutes;
c - if the central heating ow temperature is < 4°C, the burner will re
(heating position) at minimum power until the temperature reaches
33°C, the burner will go o and the pump will continue to run for two
minutes.
If the boiler is tted with a tank, a second device controls the
temperature of the domestic hot water. If this drops below 8°C,
the distributor valve switches to domestic water position and
the burner operates until the temperature reaches 12°C. This
followed by a post-circulation cycle of 2 minutes.
The anti-frost device activates only when (with the boiler operating
correctly):
- the system pressure is correct;
- the boiler is electrically powered, the symbol is illuminated;
- there is a supply of gas,
- no safety shutdown or lockout is in progress.
