SMOKE SMELL OR SOOT BUILD-UP
Because it is a wood-burning device, this stove may emit a faint wood-burning odor. If this increases beyond normal
or is you notice an unusual soot buildup on walls or furniture, check your exhaust system carefully for leaks. All joints
should be properly sealed. Also, clean your stove following instructions in “MAINTENANCE.” If problem persists,
contact your dealer.
