HEAT EXCHANGER TUBES
ONLY CLEAN HEAT EXCHANGER TUBES AFTER
STOVE HAS COOLED DOWN. A rod is located above
the heat exchange baffle (inside of firebox) is used for
cleaning the tubes. After opening the firebox door, use
the hole in the handle of the grate scraper tool to “grab”
onto the rod (see pictures on this page). Using the grate
scraper tool, pull the rod up and out towards the opening
of the firebox. Continue pulling until the tube scraper
reaches the top of the firebox.
It may be easier to clean the tubes by first removing the
heat exchanger baffle. Loosen the two screws holding
the baffle in place (do not fully remove). The baffle con-
tains keyhole slots allowing the screws to remain in place
while removing the baffle. The scraper can now be
pulled in a more horizontal manner, which allows the
scraper to move more freely.
