SAFETY DEVICES
FLUE EXHAUST BREAKAGE
If the suction device stops, the electronic board
immediately blocks the pellet supply.
PELLET FEED MOTOR STOP
If the motor reducer stops for any reason, the stove
goes into alarm mode and the fumes motor continues
to function in order to expel all combustion gas until
the minimum cooling level is reached.
DOOR MICRO SWITCH
When the stove door is opened, a safety micro
switch blocks fuel feeding.
MICRO BLOCKING INSERT
In the "Comfort idro" product there is an end
run micro switch that warns when the machine
is blocked in the running rails. If the micro switch
detects that the insert is not suitably blocked, it
blocks the passage of electric current inside the
machine.
NO IGNITION
If a ame is not developed during the ignition phase,
the appliance will go into no ignition alarm mode,
displaying “NO IGN”.
TEMPORARY POWER CUT
If the power cut is less than 10 seconds, normal
stove functioning will continue when the current
returns. If the power cut is longer than 10 seconds,
the stove "black out" alarm will occur when the
current returns, taking the product to complete
cooling. When cooling has ended it will re-start in
automatic mode.
ELECTRIC SAFETY
The stove is protected against strong current
changes by a master fuse that is found in the rear
part of the stove. (2.5A 250V Delayed).
FLUE EXHAUST SAFETY DEVICE
An electronic pressure switch blocks stove
functioning and takes it to alarm conditions.
85°C PELLET TANK BULB
If there is overheating inside the feed-box this device
blocks pellet feed motor functioning; restoration is
manual and must be performed by an authorised
technician.
The restoration of 85°C safety device is not under
warranty unless the after-sales centre can show
the presence of a faulty component.
WATER OVERHEATING SAFETY VIA 100°
C BULB
When the temperature of the water inside the
product is in proximity of 100°C, pellet feeding is
blocked. If the bulb trips, restoration of the safety
device is manual and must be performed by an
authorised technician.
The restoration of 100°C safety device is not
under warranty unless the after-sales centre can
show the presence of a faulty component.
MINIMUM AND MAXIMUM PRESSURE
PRESSURE SWITCH
A minimum and maximum pressure pressure switch
is installed in series with the pellet motor electric
energy power supply. If the pressure in the system
is below 0.6 bar, the electric energy power supply
is blocked to the pellet feed motor. If the pressure
in the system exceeds 2.5 bar, manual rearm of
the pressure switch is triggered: restoration of the
safety device is manual and must be performed by
an authorised technician.
Attention: any presence of air in the system
could cause the minimum or maximum pressure
pressure switch to also intervene. If the minimum
pressure pressure switch intervenes blocking pellet
feed into the machine, alarms may occur connected
to the lack of fuel.
Attention: For regular functioning of the product the
ideal system pressure must be calibrated at approx.
1.1 bar with cold system. Moreover, there must be no
air in the system. Extra ame recommends suitable
air vent circuit in the system. Any air venting
operations from the system or the product is not
covered by the warranty.
