17.1. MAINTENANCE OF THE EXCHANGERS

Heat exchangers must be cleaned thoroughly at the end of every heating season. During summer, the air in
basements is damper and with minimal air circulation within the furnace, it can mix with creosote and/or sooth deposits
in the exchangers to form an acid that could accelerate the corrosion process and induce premature decay of the steel.
Corrosion damages are not covered under warranty.
Smoke pipe and exchangers must be inspected regularly during the heating season. Access to the exchangers is easy
and does not require tools; just remove the decorative facing by just lifting it, remove the wing nut that keeps the
hinged access panel closed. (See pictures below)
Before cleaning the three exchanger pipes (1), pull
the baffle forward as on the drawing below. Using the
scraper (2) clean all three pipes. The dirt (4) in the
lateral pipes can be pushed forward and it will fall
directly into the combustion chamber while the dirt in
the central pipe will have to be retrieved either from
the front access panel or the rear by removing the
smoke pipe. Verify that the baffle is free of deposits
and do not forget to push it back to its original
position. Finally, close the exchanger's access panel.
