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
AF (H4) ignition failed;
H5 power failure stoppage;
H6 thermocouple failure or disconnection;
H7 excessive smoke temperature.
(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
problems. Advice for each of the cases mentioned above is
shown on the next page.
(H1) No vacuum
not close tightly (e.g. bad seal), there is an air intake or smoke
extraction problem or the combustion chamber is clogged up.
Check:
- door is closed
- combustion air extraction duct (clean it, taking care not to
clean a PC keyboard)
- pellet fire position: must not be against the wall-
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)
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
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.
Troubleshooting (Iris Plus & Little models)
Display-control panel off
no mains voltage
Remote control (optional)
not working
excessive distance from pellet fire
Outlet air not hot
too much soot in heat exchanger
No flame appears (remember
that it only appears 5 minutes
after pressing the 0/1 key)
the auger has not been filled
Ignition failure
build up of unburnt material in
combustion chamber
The ignition/off does not
start at the time required
incorrect setting:
