12. MAINTENANCE
12.1. 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, move the upper vermiculite baffle board of the combustion chamber forward
(see drawing on next page). 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. Then, ensure that the upper baffle board is free of ashes. Do not forget to push the upper
baffle board back to its original position. Finally, close the exchanger access door.
