Chimney Flashing and cap
(See FIGURE BELOW) The vent kits include a trim-able 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.
12. Attach a sheet metal strap loop to the flex end of the liner(s) and tie a rope to it. Two installers
should proceed to the roof and drop the rope (with weight on the end to make sure it goes all the
way down) and insert the liner(s) past the flexible portion, into the existing chimney – SEE BELOW:
NOTE: Repeat this step for second liner.
13.
One installer should then return to the fireplace opening and pull the rope to guide the liner(s) into
place through the smoke shelf and the damper opening to a point 22" (560 mm) above the fireplace
hearth. The person below should wear leather gloves and Safety Glasses during this process to
avoid being cut and to safeguard eyes from flying debris.
CAUTION:
WHEN USING FLEX ALUMINUM LINER, USE EXTREME CAUTION WHEN STRETCHING LINER
AROUND OFFSETS SO AS NOT TO RUPTURE LINER.
