Troubleshooting (Iris Plus & Little models)
Display-control panel off
Remote control (optional)
not working
Outlet air not hot
No flame appears (remember
that it only appears 5 minutes
after pressing the 0/1 key)
Ignition failure
The ignition/off does not
start at the time required
Possible Causes of Shutdown (Iris Plus & Little models)
WARNING!
•
THE CHIMNEY AND SMOKE DUCTS CONNECTED
TO THE PELLET FIRE MUST BE SWEPT AT LEAST
ONCE A YEAR.
•
LACK OF REGULAR CONTROLS AND CLEANING
INCREASES THE RISK OF FIRE IN THE CHIMNEY,
SHOULD A FIRE OCCUR PROCEED AS FOLLOWS:
If the pellet fire shuts down, the reason is shown on the
display.
•
H1 no depression: problem connected with air circulation;
•
H2 smoke expulsion motor failure;
•
SF (H3) flame stop;
•
AF (H4) ignition failed;
•
H5 power failure stoppage;
•
H6 thermocouple failure or disconnection;
•
H7 excessive smoke temperature.
The message is displayed until the "ON/OFF" (Little) or "0/1"
(Iris Plus) key on the panel is pressed. Do not restart the pellet
fire until the problem has been looked into and the cause
removed.
To start the pellet fire up again after a shutdown, let the
shutdown procedure end (10 minutes marked by a beep) then
press the "ON/OFF" (Little) or "0/1" (Iris Plus) key.
Never unplug the pellet fire while it is shutting down owing to
problems. Advice for each of the cases mentioned above is
shown on the next page.
(H1) No vacuum
(trips when the flow sensor detects insufficient combustion air flow)
The flow may be insufficient because the door is open, or does
not close tightly (e.g. bad seal), there is an air intake or smoke
extraction problem or the combustion chamber is clogged up.
no mains voltage
excessive distance from pellet fire
remote control battery flat
too much soot in heat exchanger
the auger has not been filled
build up of unburnt material in
combustion chamber
incorrect setting:
• clock
• programme enabling
• programme enabling for the day
Important Information
• make sure the power cord is connected
• check the house fuse
• move nearer to pellet fire
• check battery and replace if necessary
• clean heat exchanger from inside the firebox
• fill auger (see paragraph on ignition)
• clean combustion chamber
• check according to the instructions on
page 10 (Iris Plus) and page 12 (Little)
•
YOU MUST ISOLATE THE POWER SUPPLY BEFORE
EXTINGUISHING THE CHIMNEY FIRE.
•
EMPTY THE PELLET HOPPER.
•
CONSULT SPECIALISED PERSONNEL BEFORE
RESTARTING THE MACHINE AFTER THE INCIDENT.
Check:
-
door is closed
-
combustion air extraction duct (clean it, taking care not to
damage the flow sensor elements)
-
flow sensor, cleaning it with dry air (such as that used to
clean a PC keyboard)
-
pellet fire position: must not be against the wall-
combustion chamber position and cleaning (frequency
connected with the type of pellets used)
-
smoke duct (clean)- installation (if it does not comply with
regulations and has more than 2-3 bends then the smoke
outlet is not acceptable)
-
flow sensor threshold (SF in the parameters).
Cold test the sensor if malfunction is suspected. If the value
displayed does not vary when the conditions are changed, for
example the door is opened, then the sensor is faulty.
The low pressure alarm may also occur during ignition as the
flow sensor starts monitoring 90 seconds after the ignition
cycle starts.
(H2) No expulsion
(trips if the smoke extraction revolution sensor detects a fault)
-
Check that the smoke extractor is working properly.
-
Check revolution sensor connection.
-
Check that the smoke duct is clean.
