WarnInG SIGn - hot fume

One of the safety devices that controls your Ravelli Young stove, also checks
that exhaust fume temperature does not exceed a certain threshold, which
creates a hazard.
There are, however, cases in which, even during normal operation, the fume
temperature may rise slowly due to adverse weather conditions that slow
down the fume flow through the chimney, or the use the stove for several
months without proper seasonal cleaning, resultin in ash deposits that prevent
the exchange of fume heat with parts of the stove suitable to disperse it in the
house by means of the room fan or the hot fume signal indicates a possible
room fan failure. Should the above conditions be encountered, the stove will
AUTOMATICALLY switch to HO FUME state:
the O-Ring signals the operation at the set power in that very moment

through all 24 LEDs lit up in RED, every 5 seconds, alternatively to the BLUE
LEDs, and simultaneously blocks all functions - except fro stove switch-off
function;
• the room fan switches to maximum operating speed (P12-Volt 220);
pellets load is reduced to a minimum (P1).
•
This mode will remain active until fume temperature detected drops by 20°C
below the temperature set as safety alarm (250°C). The example below
shows a hot fume warning signal:

alarm 1
- BLACKOUT
If there is a blackout during machine operation, there are two possible cases:
1.
reset within 10 sec.;
2. reset after more than 10 sec.
If power is restored within the time slot of the first case, the stove will maintain
its regular operation; in the second case, upon power restoration, the stove will
enter the alarm 1 BLACK OUT state and on the O-Ring will be displayed the fol-
lowing graphics:

It is triggered when the electronic control board detects a malfunction of the
