After the Super Flex® chimney liner has been installed, but before the chimney cap is placed, the BSV top
mounted Spider Damper must be installed. The Spider Damper is placed in the top section of the Super Vent®
chimney liner.
The Spider Drop-in Damper (25-1) (Part #21) installs typically like other top mounted dampers. The bottom
hook-up is also typical. Attach the ring on the 28' stainless cable (Part #22) to the underside ring of the Spider
Damper. (25-2) The installer must go to the roof and place the Spider Drop-in Damper inside the top section of
the Super Vent® chimney liner until handles of damper don't go any further down. (25-3, 25-4) Unroll cable,
dropping it all the way down the flue until cable reaches the firebox. The important installation step to be
observed is as follows: check for tightness in between flue walls and outside damper. Any air clearance should be
sealed with flat gasket or silicone caulk. (25-5) Check damper plate to be sure it moves freely. Because blade is
counterweight, damper should always be in the opening position.
