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 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.
Flue pipe and heat 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.
Before cleaning the three exchanger pipes, pull the baffle forward as on the drawing below. Using the scraper clean all
three pipes. The dirt 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 exchangers' access panel.
12.2. CHIMNEY MAINTENANCE
The most efficient way to sweep a chimney is to run a hard chimney sweeping brush. Brush from the top down so
sooth and creosote deposits will detach from the chimney liner and fall down to the bottom of the chimney where it can
be easily removed.
The chimney must be inspected regularly and any creosote build-up must be removed without delay. Monthly cleaning
should be sufficient during cold winter months while more frequent cleaning could be required during milder periods.
