5.2. ALTERNATIVE FUEL 
 
The  alternative fuel for  coal  heating  boilers of    SAS    UWG  type  is  a  mixture  of  the 
black  coal  grades  as  follows:  70%  of  coal  the    nut  grade  (    class  24/12    acc.  to  
above mentioned norm)  and  30%   of  coal  the fine  coal  grade (class  21/15  acc. 
to above mentioned norm). For this type of boiler it is not recommended to relay only 
on the fine coal.  
These boilers are also fit for combusting long flame fuels, such as:  brown coal and 
wood in different forms, e.g. chips, silvers, shavings, etc.  

 

The wood has to be seasoned at least one year! 
Wet  wood  combustion  lowers  the  efficiency  and  the  lifetime  of  a  boiler.    It  also 
obstructs the declared power for slow combustion sustainment.  

 

 

 
 

 
 
 
 
Boiler’s assembling  should  be  performed    by  qualified  and  authorized  personnel   
(qualified  person upon adequate training and authorized for performing maintenance 
and repair works). The  fitter’s  obligation  is  to  get  familiar  with  the  product, its  
functioning  and  protection  systems functionality. 

 

 
Prior to boiler’s  assembling  it  is  strictly necessary  to  get familiarized  with  
the content  of  hereby Technical-Start-Up Documentation. 

 
6.1. REQUIREMENTS FOR BOILER-ROOM 

 
The  boiler  room,    where  the  heating  boiler  for  central  heating  installation  shall  be 
installed, must conform the requirements of detailed regulations being in force, at the 
country of destination (e.g. PN-87/B-02411). 

 

In particular, the following requirements shall be fulfilled: 

 

the    boiler    rooms    should    be    located    as    centrally    as    possible    to    rooms  
which  are  covered  with  heating system,  and the boiler itself should be placed 
as close as possible to  chimney  (chimneys),  

 

boiler  room  entrance  door  should  be  opened  on  the  outside,  and    be  made  of 
inflammable materials. 

 

the  boiler  room  should  have  air  blow-in  ventilation,  a  channel    with  section  
no  less  than  50%  of  the chimney  section,    but  not less  than   21   x   21   
cm,   with  the exit at the back  part boiler’s  room,  (lack of such ventilation or 
obstruction may cause: smoking,  inability to get higher temperature),  

 

the  boiler  room  should  have  air  blow-out  ventilation  under  room’s  ceiling  with 
section no less than 25%  of the chimney  section,  but  not less than  14   x   14 
cm (the purpose of  this system is to  carry out   harmful gases).

 

 

NOTE: Employing of  mechanical blow-out ventilation is  unacceptable. 
The boiler room should be provided with day and artificial lighting.
