off state
Once you have checked that the I/O switch on the back of the stove is set to OFF
and you have connected the power cord to the stove and the socket equipped
with a protective earthing system, bring the switch to I. The O-Ring will display
a BLUE blinking light through the first LED on top right, as shown in the figure:
Switch on
Press and hold the middle push-button/potentiometer until the LEDs, in groups
of 6, start rotating clockwise. Release the push-button and wait for the stove to
start working. The animation will be executed throughout the switch-on phases:
initial loading, ignition and stabilization. Once the stove switches to WORK sta-
tus, the LEDs will be displayed differently.
Work phase
Once the initial phase has been completed successfully, LED movement
stops and the display will indicate the operating power selected when the
stove was turned off the last time. Turn the knob clockwise to increase the
power and the heat output by the stove - turn it counter-clockwise to de-
crease the power and speed of the fan. Please note that the O-Ring features
12 powers, each of them being indicated by the ignition of the 2 BLUE LEDs .

By increasing the power via the knob you will get an equal increase in room fan
power, perceiving an immediate feeling of warmth. The real power of the stove
instead, will increase gradually, by steps of 20 seconds each, to prevent brazier
clogging, or worse, that the stove shuts off due to the sudden increase of com-
bustion air. Avoid increasing and decreasing the power of the stove continuously:
given the fact that this is a heat generator fueled with biomass, increases and
decreases will never be immediate. The stove requires a few minutes to reach the
powers selected, especially when switching from minimum to maximum, or vice
versa, by a single operation.

The stoves of Young series are equipped with brazier cleaning function, through
increased blow of combustion air at fixed intervals, aimed at keeping the brazier
effective, avoiding unpleasant deposits. During brazier cleaning, all

lasts about twenty seconds.
