SF (H3) No fire
(Trips when the thermocouple detects that the smoke temperature is
- a lack of pellets
- the maximum temperature thermostat has tripped
(this is unusual as it would indicate an excessive smoke temperature)
AF (H4) No start
maximum of 15 minutes).
Distinguish between the following two cases:
No flame has appeared
Check:
- position and cleaning of the combustion chamber
- that the combustion chamber receives combustion air
- that the heating element is working- room temperature
Try lighting with firelighter
A flame has appeared but AR is displayed after AF
Check:
- that the thermocouple is working correctly
- that the start temperature is set within the parameters
(H5) Power Failure stoppage
H5 error power restored after power failure, both fans will run
is fully cooled, the fans will stop after approx 15 minutes.
Press O/l twice to restart. Check electrical connection and
voltage drops.
(H6) Thermocouple Fault
(Trips if the thermocouple is faulty or disconnected)
Check connection between the thermocouple and the circuit
board. Check operation during cold testing.
(H7) Over temp
(Shut down due to excessive smoke temperature)
Excessive smoke temperature may be caused by: type
of pellets, smoke extraction fault, blocked duct, incorrect
installation or gearmotor “drift”.
Troubleshooting (Iris Plus & Little models)
After each bag of fuel
Clean with a vacuum cleaner when the pellet fire is cold. To
protect your vacuum cleaner, we recommend always using
a vacuum pot connected to your vacuum cleaner, which are
available from your Metro Dealer. The whole process takes
only a few minutes a day.
- Vacuum-clean the door, vacuum-clean the hearth and
vacuum-clean the space around the combustion chamber
where the ash falls (there is no extractable ash pan).
- Remove the combustion chamber or clean it with a
scraper, and unblock any blocked holes on all sides.
- Vacuum-clean the combustion chamber compartment,
clean touching edges and replace the combustion
chamber.
- If necessary clean the glass with glass cleaner (when cold).
After a few months use dry air (PC keyboard type) to clean the
Every season (by a qualified technician)

General internal and external cleaning.
- Carefully clean the heat exchange pipes.
- Carefully clean and de-scale combustion chamber and
corresponding compartment.
- Clean fan and mechanically inspect play and fastenings.
- Clean the vent system.
and check thermocouple.
- Clean, inspect and de-scale ignition heating element
compartment and change the heating element itself if
necessary.
- Clean/check display-control panel.
- Visually inspect electric cables, connections and power cord.
- Clean pellet hopper and check auger-gearmotor assembly
