Lockout of the stove
The following things can cause the stove to lock out:
•
Overheating of the stove body
• High pressure in the outlet fumes (as read by the pressure
switch) and therefore possible obstruction of the smoke
discharge system or external back-pressure.
The lockout is indicated by the LED (6) lighting up, accompanied by an
audible "beep".
In this situation the shutdown cycle is automatically activated.
Once this process has started, any operation which is an attempt to
reset the system is useless.
The cause of the lockout is shown on the display (8).
WHAT TO DO:
When the stove is cold:
If the message "Alarm hot pel" appears, it will be necessary to
unscrew the cover of the thermostatic sensor fitted to the back of the
stove and press the red button to reset it. Refit the protective cover.
Fig.24-25
If the message "Alarm Press" appears, you need to check if ALL of
the smoke duct, including the combustion chamber, is clean and free of
obstructions. (it is advisable to have this done by a specialized MCZ
technician)
Only after the cause of the blockage has been permanently
eliminated can a fresh attempt to relight the stove be made.
