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.
