the center of the appliance at the same time until they are
disengaged from the locating holes. Repeat for bottom spring
latches and pull louver outward.

wall on the flue exit side of the firebox (see Figure 1). There
are four magnets on the bottom of the blower assembly that
will keep the blower in place on firebox bottom. Note: If the
blower kit is not installed flush against the inside side wall of
the fireplace, the circulating air from the blower system will
not flow properly.
