In the event of lapsed or inadequate cleaning the 

heat stove might have functionality issues such 

as:

• poor combustion

• glass blackening

•  burn pot clogging with accumulated ash and 

pellets

•  ash deposit and excessive scaling on the ex-

changer leading to poor performance.

The internal electrical-mechanical components 

must be exclusively checked by skilled personnel 

having technical knowledge in combustion and 

electricity.

Cleaning the surfaces

As the stove is a heating appliance, its outer 

surfaces are especially hot.

For this reason the utmost caution is recommended 

during operation, namely: 

• Do not touch the housing of the stove and the 

various components, do not go near the door, it 

might cause burns, 

• Do not touch the flue gas exhaust

• Do not perform any kind of cleaning

• Do not discharge the ashes; 

• Do not open the ash pan;

• Be careful to ensure children do not go close. 

All cleaning operations of all parts must be carried 

out with stove completely cold and electrical plug 

disconnected.

To clean the surfaces, use a rag soaked with wa-

ter or, at most, with water and neutral soap.

For safety reasons, the frequency with 

which to clean the flue gas exhaust sy

-

stem must be established according to 

the frequency of stove use.

These operations must be performed 

by a skilled technician or by the user 

who will take on responsibility for 

them, in the event of any damage during 

maintenance.

Perform this maintenance with cold heat stove 

and  powered  off. This  maintenance  is  at  the 

customer's expense if it is performed by an 

authorised service centre.

Using aggressive detergents or thinners 

can damage the stove surfaces. Before 

using any type of detergent, we recom-

mend testing it on a spot out of sight or contact-

ing the Authorised Service Centre for advice.

It is therefore recommended to perform this 

yearly periodic maintenance (possibly with a 

scheduled service contract) aiming at visual and 

operation inspection of the following compo-

nents:

• gearmotor

• 

flue gas ejection fan

• 

flue gas probe

• exchanger fan

• igniter

• pellet reset thermostat

• room probe

• pressure switch

• electronic board

• panel - electronic board protection fuses

Heat stove maintenance and cleaning

Cleaning warnings

All cleaning operations of all parts must be carried 

out with stove completely cold and electrical plug 

disconnected.

Before performing any maintenance operation on 

the stove, take the following precautionary meas-

ures:

•  ensure all parts of the stove have cooled off;

•  ensure the ashes are completely out;

•  ensure the main switch is at OFF;

•  unplug the stove thus avoiding accidental con-

tacts;

• when maintenance is over, check that every-

thing is in order as before the intervention (plac-

ing the burn pot properly).
