Following the consumption of the entire tank of pellets the combustion chamber must be cleaned by vacuuming and/or 
removing all debris generated by pellet burning.  
Incompletely burned pellets should never be returned to the pellet tank or disposed of in the container for ashes.  

 

 

INSPECTION AND PARTS THAT NEED TO BE MAINTAINED  

CHECK THE ITEMS LISTED BELOW TO ENSURE PROPER OPERATION OF PELLET BOILERS. THESE PRECAUTIONS 
ENSURE THE MAXIMUM OUTPUT OF THE BOILER AND THE TEMPERATURE OF THE SYSTEM: 

     

    Make sure that the pellet boiler and ashes in it are cold. 

 

For a complete cleaning every week or after 200 kg of pellets have been consumed (whichever is earlier) the 
ashes underneath the firebox and from the combustion chamber must be vacuumed. You can use a brush to 
clean the walls of the firebox.  

 
GENERAL CLEANING OF THE BOILER AT THE END OR BEGINNING OF THE HEATING PERIOD: 

 

          Make sure that the boiler and ashes in it are cold. Turn off the power supply to the boiler. 

 

Upon completion of the heating period, disconnect the power supply to the boiler. It is very important to clean 
and inspect the boiler as described in this manual. 

 

The door seal may get detached after some time, although it is attached with glue resistant to high temperature. 
To reattach the seal apply an adhesive resistant to high temperature on the back side of the seal. In this way the 
sealing of the firebox door is guaranteed. 

                    CONNECTION OF THE FLUE PIPE TO THE CHIMNEY (should be cleaned at the end of each heating season). 

   

           Make sure that the pellet boiler and ashes in it are cold. 

                     - The flue pipe, chimney and chimney cap should be inspected and cleaned annually. To carry   out the 
procedure professionally, you should contact the chimney sweep. 

 

 

ADDITIONAL MAINTENANCE 

Your pellet boiler is a source of heat in which only pellet may be used.  Annual maintenance of the boiler can only be 
performed by a person authorized by the Alfa Plam company a.d.  
Regular annual service will preserve proper operation of the heating units, ensure their greater efficiency, keep the 
warranty valid and extend the life of the machine itself.  
It is recommended to carry out the procedures described in the previous section at the end of the heating period. The 
purpose is to verify and ensure proper operation of all components.

IMPORTANT SAFETY INFORMATION 

 

You have purchased the highest quality product. 
The supplier is at your service for any information you may need. Proper installation of the boiler, carried out in 
accordance with the attached guidelines, is important for the prevention of any defect, risk or danger of fire.  
The pellet boiler works on the basis of underpressure generated in the combustion chamber, therefore it should always 
be ensured that the joints to the chimney are sealed and tight. 

 

In the event the chimney catches fire, people and animals should immediately leave the residential area. Disconnect the 
power supply to the main switch immediately after that, or cut the plug out of the socket (only if you are not putting 
yourself at risk), and contact the fire department. 
 

 

For safety purposes and preservation of function of the pellet boiler, do not use finely chopped wood. 
 

 

Do not use the pellet boiler for incineration.

PELLET QUALITY IS VERY IMPORTANT 

 

The quality of pellets is very important! 
The boiler is designed to use pellets. Considering that a variety of types and sizes of pellets are available on the market, it 
is important to choose pellet that contains no impurity, which is compact and does not generate dust.
