TROUBLESHOOTING TIPS FOR KELLY
In the event of problems the stove stops automatically and runs the shutdown process and the display shows text
regarding the motivation of the shutdown (see the various alarms below).
Never pull the plug during shutdown on account of malfunction.
To start the stove up again after a shutdown, let the shutdown procedure end (10 minutes marked by a beep)
then press the 0/1 key.
Do not turn the stove on again before checking the cause of the malfunction and CLEANING/ EMPTYING the crucible.
INDICATION OF POSSIBLE CAUSES OF MALFUNCTION AND INDICATIONS AND REMEDIES:
1) H1 No Depression (this trips if the flow sensor detects insufficient combustion air flow)
Turns off for lack of depression
Air flow may be insufficient because the door is open, the door does not close properly (e.g. bad seal), there is an air
intake or smoke extraction problem, or the combustion chamber is clogged.
Check:
- door closure;
- combustion air intake duct (clean, paying attention to the flow sensor components);
- clean the flow sensor with dry air (like that used for PC keyboards);
- stove location: it must not be installed against a wall;
- combustion chamber position and cleanliness (clean regularly according to the type of pellet);
- smoke duct (clean);
- installation (if it does not comply with regulations or the smoke outlet has more than 2-3 bends);
If you suspect the sensor is malfunctioning, carry out cold tests. If the conditions are changed (for example by opening
the door) and the value does not change, there is a sensor problem.
The no depression alarm may also occur during ignition, since the flow sensor starts monitoring 90 seconds after the
ignition cycle begins.
2) H2 Smoke expulsion motor failure (this trips if the smoke extraction speed sensor detects a fault)
Turns off due to smoke expulsion motor
- Check smoke extractor function (devolution sensor connection) and board.
- Check smoke channel for dirt
- Verify the electrical system and earthing system.
- Check eletronic circuit board
3) SF (H3) Flame stop (this trips if the thermocouple detects a smoke temperature lower than the value set, which it
interprets as the absence of flames) Turns off due to drop in smoke temperature
Flame may fail for any of the following reasons:
- lack of pellets
- too many pellets have suffocated the flame
- the maximum thermostat has intervened (rare, this only intervenes in the event of excessive smoke temperature)
4) AF (H4) No start (intervenes if a flame fails to appear within a maximum of 15 minutes, or if ignition temperature
is not reached). Turns off due to incorrect smoke temperature during ignition
Distinguish either of the following cases:
the flame does NOT appear
Check:
- combustion chamber position and
cleanliness;
- arrival of combustion air in the combustion
chamber;
- if the heating element is working;
- room temperature (if lower than 3°C use a
firelighter) and damp.
Try to light with a firelighter.
Flames appear, but AF appears on the display after Ar
Check: (only by the Dealer)
- if the thermocouple is working;
- start-up temperature setting in the parameters.
