With access to the inside of the heat exchanger through the burner area, cleanout 
openings, and vent terminal connection, it is now possible to use a long, flexible wire 
brush and an industrial type vacuum cleaner to remove any soot build-up.  
 
NOTICEA one inch (outside diameter) vacuum cleaner hose will fit into the 
radiator.
 
 
To vacuum and brush the horizontal drum of the heat exchanger, enter the drum 
through the clean-out openings in both directions. 
 
2.  Heat Exchanger Reassembly 
  
After the heat exchanger has been cleaned, install the heat exchanger and 
reassemble the components to their factory produced state, in reverse order of 
disassembly and removal, refer to figures 9 and 10. Remount the burner being 
certain that the air tube is properly inserted into the chamber opening. If heavy 
soot deposits were found in the heat exchanger, this indicates that the burner 
may be out of adjustment. Reset the burner, as indicated under the Initial 
Burner Operation section.
