Introduction

 

 

UAB “Biokaitra” says thank you and congratulates you with your new purchase – the heating device. Your 
purchased multifunctional boiler is fired with 

straw, wood sawdust and other agro-pellets.

  

 

The modern construction and the most advanced methods of steel manufacturing have allowed us to create a 
cheap heat energy source for your home, commercial or agricultural buildings with the area of up to 240 m

2

.  

While designing the Bio series boilers, we focused on satisfying your needs and paid attention to long term 
observations  and  customer  feedback.  This  allowed  us  to  manufacture  an  easy-to-use  boiler  with  the 
efficiency ratio of 91.5 %. 

 

Recommendations  

Before use 

 

-      Please check the device and its contents. 
-      Please read the safe operation manual carefully. 

Before installation, it is necessary to familiarise with the boiler installation section carefully. 

 

NOTES!

 

During  the  transportation  of  boiler,  it  is  necessary  to  take  care  of  the  protection  of  boiler  and  its 

components from mechanical damage. 
- Before installation the boiler has to be stored in a dry place. 
- For connection of boiler to the power network, water supply system and chimney please refer to the valid 
norms, requirements and the user manual.  
- The manufacturer is not liable for any losses resulting from improper installation of the device. 
- In case of emergency, it is necessary to contact the authorised service as soon as possible. 
- Intervention of persons without an adequate qualification may result in the damage to the boiler. 
- Use only genuine spare parts for the repair works.   

 -  The  boiler  and  the  bunker  frame  are  subject  to  3  year  warranty,  provided  that  the  annual  inspection  of 
boiler is performed and the respective information is recorded in the warranty sheet. A warranty of one year 
is  provided  to  the  moving  parts  that  are  subject  to  wearing,  i.e.  screw  conveyor,  motoreducers  and  motor, 
ventilator, controller and insulation rope. The warranty does not apply to the boiler deflector! 

 
- A warranty sheet and warranty conditions are enclosed to this manual. 

 

Purpose of boiler with burner 

 

 

-

 

Bio

 boilers with automatic fuel feeder and burner are used for the combustion of straw, wood sawdust and 

other agro-pellets of the diameter of 6-10 mm.  

-

 

Bio

  boilers  are  modern  water  heating  boilers  used  for  the  production  of  heat  and  hot  water  (with  bulk 

household water heaters - boilers) used for heating residential and industrial buildings.   

-

 

Bio

 boilers are fitted with an automatic screw fuel feeder (conveyor), burner and fuel tank to store fuel for 

several days upfront (3-7 days). Boiler’s screw fuel feeder, ventilator and circulatory pump are controlled by 
modern  automation.  Fuel  control  system  allows  to  program  the  combustion  process  according  to  the 
maintenance conditions, weather and fuel quality. 

-

 

Bio

 boilers do not require constant combustion, because the fuel is dosed by the automatic screw conveyor, 

whereas the burning takes place thanks to the ceramic heating element.
