(See FIGURE 4A) The vent kits include a trimable flashing. Measure, trim and shape flashing to fit the
existing flue liner. This flashing prevents water and small animals from entering area between the chimney liner
and flue liner. Plan for 1" to 1-1/2" (25 mm to 38 mm) overlap on each side. Center the flashing and mark it
about 3" (75 mm) larger in each dimension than the existing chimney. Trim the notch with snips and bend edges
with hand seaming tool, metal break or pliers.
