ALARM ALERTS

In the event an operating anomaly occurs the stove starts switching off due to the alarm and informs the user of the type of fault that has taken place via a 3 digit code which stays displayed on the rear emergency panel.

The alarm is indicated permanently by the relative 3 digit code, by a flashing red LED that lights up on the emergency panel and an intermittent sound signal for the first 10 minutes of the alarm. Read the instructions in the following 2 paragraphs to cancel the alarm status and restore the normal operating mode of the stove.

The following table describes the possible alarms indicated by the stove, associated to the respective code that appears on the emergency panel and helpful tips to solve the problem.

MESSAGE ON DISPLAY

A01

A02

TYPE OF PROBLEM

The flame does not light

The flame is goes out unexpectedly

SOLUTION

Check the level of pellets in the tank.

Check that the brazier is correctly positioned in its seat and has no incrustation or unburned material.

Make sure the ignition plug warms up.

Thoroughly empty and clean the brazier before restarting.

Check the level of pellets in the tank.

Check that the brazier rests correctly in its seat and has no visible deposits of unburned pellets.

A03

The temperature of the pellet hopper exceeds the required safety threshold.

The structure overheats due to reduced heat dissipation.

The structure is too hot because the product has been used for too long at the maximum power or there is poor ventilation. When the product is sufficiently cold, press button B on the control panel or OFF on the remote control to cancel alarm A03. Once the alarm is cancelled, the product can be switched on normally.

A04

A05

The temperature of the exhaust smoke has exceeded certain preset safety limits.

The stove switches off automatically. Let the stove cool down for a few minutes and then switch it on again.

Check the smoke expulsion and verify the type of pellet used according to the instructions found in Chap. 2 of this manual.

Chimney flue clogged - wind - door open. Check the smoke duct and make sure the door is closed.

The smoke extractor fails to guarantee sufficient primary air, required for correct combustion.

Draught difficulties or brazier clogged.

Check whether the brazier is clogged and clean it, if necessary.

Check and if necessary clean the smoke duct and air inlet.

SER

Electronic control unit overheating

Faulty air flow rate sensor

Routine maintenance warning after 2000 hours of operation

The structure is too hot because the product has been used for too long at the maximum power or there is poor ventilation. When the stove is sufficiently cold, press button B on the control panel or OFF on the remote control to cancel alarm A13. Once the alarm is cancelled, the product can be switched on normally.

This alarm does not block the stove, just a warning is displayed. Contact an authorised service centre to have the component replaced.

When this flashing message appears upon start-up it indicates that the preset operating hours before maintenance is due have elapsed and that an MCZ qualified technician must be contacted for maintenance.

Exiting the alarm conditions

Follow the procedure described below to restore normal stove operation after an alarm has been triggered:

• Put selector D on the rear emergency panel on OFF for a few seconds, until the 3 digit alarm identity code disappears. The red LED stops flashing and the sound signal is silenced by performing the steps below.

• Put selector D back in the REMOTE position, to control the operation of the stove via the remote control.

• Switch off the remote control and switch it on again if one wants to restart the stove.

Mechanical stove block

The following conditions may cause the mechanical stove block:

• Structure overheating (“A03”)

• Smoke overheating (“A04”)

• During stove operation air has entered the combustion chamber or there is an obstruction in the chimney flue (“A05”)

The block is signalled on the display and with a sound signal. In this situation the shutdown stage is activated automatically.When this procedure is started, any test operation to restore the system is useless. The display signals the cause of the blockage.

SOLUTIONS:

If “ A03 ” appears: the structure is too hot because the product has been used for too long at the maximum power or there is poor ventilation.

When the product is sufficiently cold, press button B on the control panel or OFF on the remote control to cancel alarm A03 . Once the alarm is cancelled, the product can be switched on normally.

If “ A04 ” appears: The stove switches off automatically. Let the stove cool down for a few minutes and then switch it on again. Check the smoke expulsion and verify the type of pellet used according to the instructions found in Chap. 2 of this manual.

If “ A05 ” appears: the door has been left open for too long or a significant amount of air has entered (e.g. missing smoke fan inspection cap). If these causes are excluded, check and if necessary clean the smoke duct and flue. (it is recommended that this operation is carried out by an MCZ qualified technician.

The product can be switched on again only after having eliminated the cause permanently.
