Refer to the Insulation Sleeve Instruction section.
Step 2. Measure and record the dimensions to
determine total Flex Liner requirements.
Step 3. Unpack and unroll the Flex Liner. Attach
Spacers to the Flex Liner to insure the liner maintains
the 1" clearance required to the inside of the masonry.
Place Spacers every 5 feet on the Liner.
Step 4. Secure a rope to the Flex Puller and attach
the Flex Puller to the Dura Flex SS Flex Liner. One
person should feed the liner through the chimney from the top, while another should
pull the liner from the bottom (Figure 4). Two people are needed to be sure that the
Flex Liner is not damaged or torn.
Step 5. After the Flex Liner is pulled through the damper area, attach the Flex
Connector (be sure the Flow arrow points up, the direction of the exhaust flow) to
the Flex Liner and tighten the fast connect band. Position appliance, then insert Flex
Connector into the flue outlet on top of the fireplace insert, tighten the fast connect
band directly to appliance outlet or collar. To further insure the connection between
the Liner and the Appliance, use (2) 3/8" screws to secure the Flex Connector to
appliance outlet, penetrating through both the band and appliance outlet (Figure 13).
Step 1. When terminating your Flex Liner installation, insure the Flex Liner extends

the base of the Top Plate to fit on the masonry chimney as needed.
Step 2. Slide the Top Plate over the Flex Liner and seal the Top Plate to the masonry
