MAINTENANCE OF THE EXCHANGERS

The flue pipe and the exchangers should be inspected regularly during the burning season. Easy access is provided
(without the use of tools): simply unscrew the wing nut on the exchangers access door. See pictures below.
WARNING: THE HEAT EXCHANGERS ARE TO BE CLEANED THOROUGHLY AT THE END OF EACH HEATING
SEASON. DURING THE SUMMER AIR IS MORE HUMID WITH MINIMAL NATURAL FLOW IN THE FURNACE, IN
THESE CONDITIONS, REMAINING CREOSOTE AND/OR SOOT IN THE EXCHANGERS WILL PRODUCE AN
ACID THAT WILL ACCELERATE THE CORROSION PROCESS AND WILL PERFORATE THE STEEL
PREMATURELY, WHICH IN RETURN, WOULD NOT BE COVERED UNDER THIS WARRANTY.
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 it's original position. Finally, close the exchanger access door.
