Then set as follows:
−
external thermostat: set a temperature of 7°C;
−
external chronothermostat: set a temperature of 7°C, disable the chrono functionality in the menu 03 and
set the STANDBY function to ON. When the set temperature is reached, the stove will shut down and not
go to modulation.
In this case, however, it is advisable to use the stove time programming function and only the external
chronothermostat set temperature function.
In fact, only with this joint setting is it possible to set STANDBY to ON or OFF, obtaining respectively
modulation or shutdown when the SET temperature is reached and likewise obtaining shutdown and lighting
according to the set time programming.
When the external thermostat requests stove operation, the corresponding symbol will light up on the display.
4.10 Idle period (end of season)
If the stove is not used for long periods, and/or at the end of each season, it is advisable to proceed as follows
- remove all the pellets from the hopper;
- disconnect the power and remove the power cable;
- clean thoroughly and, if necessary, have any damaged parts replaced by qualified personnel;
- protect the stove from dust with suitable covering;
- store in a dry and safe place protected from atmospheric agents.
The standard output of the hot air supply duct is vertical, at the request of the customer can place a rear valve kit
that allows the hot air pipes choked on the left and right channel.
Any modifications must be done by authorised and competent personnel; changes made at random can
cause serious damage to the stove, for which COLA declines any liability.
5 STOVE CLEANING
Stove cleaning is very important to ensure correct operation and to prevent: blackening of the glass, poor
combustion, deposits of ash and unburnt products in the brazier, reduced thermal efficiency.
The stove must only operate with the fire door closed.
The fire door seals must be checked periodically to prevent any air from entering; the combustion chamber and
pellet duct work in a negative pressure and the fume exhaust in a positive pressure.
Routine cleaning is normally carried out by the customer following the instructions in the manual, whereas
extraordinary maintenance, at least once a year, must be performed by the authorised Service Centre.
- Cleaning operations for all parts must be carried out with the stove unplugged and cold;
- Dispose of cleaning waste in accordance with the current local regulations;
- The stove must not be operated without its cladding;
- Avoid the creation of smoke and unburnt products during lighting and/or normal operation.
Given below are the control and/or maintenance operations for correct stove use and operation.

5.1 Cleaning the brazier
Remove the brazier and the ash deposited in the combustion chamber and brazier holder. A suitable vacuum
cleaner may be used for this purpose. This operation must be carried out daily, especially in case of accumulated
unburnt matter, to ensure perfect combustion conditions, since the brazier holes allow the flow of combustion air.
