The heat stove needs simple and accurate 

cleaning  in  order  to  always  assure  effi  cient 

performance and regular operation. 

During internal heat stove cleaning the fl ue gas fan 

may be started to prevent spilling out the ashes. 

Button 

 and then button   must be pressed 

to actuate this function. The display reads “

PUL 

STUF” (stove cleaning).

To stop the fan just press and hold button   or 

wait for a cleaning cycle to be completed (255 

seconds) . Use the suitable tool to clean the 

burn pot from ashes and any scaling which might 

obstruct the air holes. In the event the pellets 

have run out in the tank, uncombusted pellets 

might accumulate in the burn pot. Always empty 

the burn pot from residues before every ignition. 

Remember that only a correctly positioned 

and cleaned burn pot is able to assure optimal 

ignition and operation of your pellet heat stove. 

When positioning the burn pot, accurately ensure 

its edges fully adhere to its housing and that the 

hole matches the pipe where the resistor is laid. 

There must not be any combustion residues in 

the contact area between the edges of the burn 

pot and the holder's support surface.

Daily check-up

Reduced or lack of cleaning may cau-

se failed ignition, resulting in damaging 

the heat stove and the environment 

(possible emissions of non-combusted mate-

rial and soot).

Do not put any pellets that failed to light back 

into the burn pot.

Exchanger cleaning (with stove off )

Scaling acts as insulation and the thicker it is, the 

lower the heat conveyed to water and the structure 

in general. It is therefore very important to clean 

the shell and tube, also called exchanger, to 

prevent scaling and clogging and jamming of the 

cleaning  device.  Just  quickly  push  and  pull  the 

lever 5-6 times so that the springs may remove 

the accumulated soot on the piping.

Check every 2-3 days

 

Clean the compartment around the burn pot (the 

fi re plate) from the ash, pay attention to hot ash. 

Only when the ash is completely cold is it possible 

to also use a canister vacuum cleaner suitable to 

picking up particles of a certain size.

Cleaning ash pan and combustion chamber 

including the igniter duct.

Cleaning the glass

To clean the ceramic glass it is recommended to 

use a dry paintbrush or, in the event of thick dirt, 

the  specifi c  spray  detergent,  use  sparingly  and 

wipe with a cloth.

Do not spray the product on the

painted walls and on the door gaskets 

(ceramic fi bre cord) because

they might be damaged.
