MAINTENANCE OF THE EXCHANGERS

The smoke pipe and the exchangers should be inspected regularly during the heating
season. Easy access is provided (without the use of tools): simply unscrew the wing nut on
the exchangers' access panel (see pictures below).

Before cleaning the three exchanger pipes, move the upper plate of the combustion
chamber forward (see drawing below). Using the scraper, clean the three exchanger pipes.
The accumulated dirt in the side 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. Make
sure that the upper plate is free of ashes and do not forget to put the upper plate back in
its original position. Close the exchangers access panel.
