Boiler conversion from right-hand design to the left-hand design 

 

Remove  the  grate  and  pull  out  the  burner  with  the  mixer  from  the  boiler  dram  (fixtures  are  as  follows:  
6 pc screw M10 x 30, 6 pc washer 10.5). 

 

From the left side of the base, unscrew the blind flange, insulation, insulation bracket (see Fig. 17) and install 
them  on  the  right  side  (fixtures  are  as  follows:  4  pc  screw  M10  x  30,  4  pc  washer  10.5).  Remove  the  old 
mastic. The metal plates between the base and the insulation bracket and between the insulation bracket and 
the blind flange must be sealed with mastic.  

 

Apply mastic to the burner flange with the mixer and insert the burner into the boiler drum from the left side and 
screw it (fixtures are as follows: 6 pc screw M10 x 30, 6 pc washer 10.5).  

 

Apply  a  reasonable  quantity  of  new  mastic  to  the  bearing  surfaces  and  mount  the  grate  in  the  burner.  Note: 
The cutting of the grate must be always directed to the inlet of the fuel feeder.

Then proceed according to Chap. 5.2 – Installation procedure. 

 

Jacket the boiler (see Chap. 5.2.2). 

Apply  mastic  to  the  fuel  feeder  flange  and  connect  it  to  the  boiler  basement  (fixtures  are  as  follows:  4  pc  nut 
M10, 4 pc washer 10.5). Rotate the motor in such a way that it is in the front when viewing the boiler from the 
front.  

Apply  the  boiler  mastic  to  the  marked  point  and  put  the 
grate  on  the  retort  with  the  mixer.  It  is  necessary  to 
ensure tightness between the burner and the grate.
