SWITCHING-OFF FAILURE DURING WORKING PHASE

If the flame extinguishes during the working stage and the smoke temperature goes

lower than the minimum working threshold, the alarm does go off and the turn-off

stage will be immediately activated (see drawing D91).

To deactivate the alarm press button 3 and the thermo-stove or insert will come to the

normal state after doing the final cleaning.

10.7

THERMAL ALARM

If in working phase the thermal security alarm shows up (see drawing D92), the

turn-off stage will be immediately activated. This alarm means an overheating of the

internal part of the pellet storage tank, this device locks the operation of the machine.

The restart needs to be done manually by an authorised technician.

The replacement of the 90ºC safety device is not included in the warranty unless

the technical assistance centre demonstrates a faulty component.

10.8

COMBUSTION CHAMBER PRESSURE ALARM

This alarm is triggered when there is a pressure change in the combustion chamber

(door open, dirty ash reservoirs, down draughts, blocked flue...). The electronic

pressure switch locks the working of the thermo-stove or insert and shows the alarm.

After that the turn-off stage will be immediately activated (see drawing D93).

10.9

LACK OF PRIMARY AIR INTAKE FLOW ALARM

Your thermo-stove or insert hydro has a flow sensor placed inside the primary air

suction pipe. It detects the proper circulation of combustion air and the smoke

exhaust. In case of insufficient air intake (due to incorrect smoke outlet or improper air

intake), the sensor sends a "lock" signal. After that the turn-off stage will be immediately activated (see drawing D94).

10.10

WORM GEAR FAILURE ALARM

The control of the fuel load delivered to the thermo-stove or insert is automatically

monitored through the electronic programming. This alarm goes off in the event that

the auger breaks down and feeds continuously. If this happens, the thermo-stove or

insert stops and the display will show the following alarm. Immediately afterwards, the

turn-off stage will be activated (see drawing D95).
