Dropping Flex Vent Liners
Figure 4-10 Installing Flex Liners
1. Measure the chimney height from the top of the chimney (or the existing flue liner) to a point 12" (300 mm) above the
floor of the fireplace insert hearth. It may be necessary to drop a rope and measure the rope itself. Be sure to allow for
all offsets in existing chimney. Cut the 4" diameter flex liners to this measured length.
2. 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 su
re it goes all the way down) and insert the 4” liners past the
flexible portion, into the existing chimney.
3. One installer should then return to the fireplace insert opening and pull the rope to guide the liner(s) into place
through the smoke shelf and the damper opening to a point 12" (300 mm) above the fireplace insert 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.
