Remove the upper side access panel, and the cover of the plenum chamber.
(see section 4.3). Clean out all accumulated soot and debris using a vacuum
cleaner. Also clean any accumulated soot from the fan impeller located at the
back of the plenum chamber. If the accumulation of soot on the impeller is
great it may be necessary to remove the motor/impeller assembly from the
back of the plenum chamber to give good access for cleaning.
