MAINTENANCE OF THE EXCHANGERS 

 
 
    The evacuation pipe and the exchangers should be inspected regularly during the burning season.  Easy access 
is provided (without the use of tools): unscrew the wing nut on the exchangers access door. See pictures below. 
 

   

 

 
 
 
 

    Before cleaning the three exchanger pipes, move the upper plate of the combustion chamber forward.  Using the 
scraper, clean the three exchanger pipes.  The accumulated dirt in the lateral exchangers will fall into the 
combustion chamber; the dirt in the central exchanger will have to be removed from the front or the back of the 
furnace.  After cleaning the exchangers, make sure that the upper plate is free of ashes and  do not forget to push 
the upper plate back  to its original position.  Finally, close the exchanger access door.
