top of the inner (upper) chimney should be exposed from the outer
(lower) chimney to allow air recirculation.

on the wall, and align the screw hole on both sides of the support bracket
with the previously marked inner (upper) chimney screw locations on the
wall. Make sure the support bracket is level, and mark the (2) mounting
screw locations.
