Vent Adapter Installation Instructions
1. Prior to sliding Insert into Fireplace insert Cavity, attach the Vent Adapter Box (Colinear or Coaxial, depending on your
selection) to the two 4" flex pipes [or the 4" and 6" coaxial liners] you dropped down the chimney. Secure the flexible pipes
to the Vent adapter starter collars using hose clamps and 4 equally spaced self-drilling screws. Create a proper airtight seal
at both pipe connection joints.
2. Remove the ceiling baffle from inside the firebox. Remove two ¼" Hex Hd. Screws that secure the baffle to the firebox ceiling,
then slide the baffle out of the firebox.
3. Slide Insert into Fireplace insert Cavity and position it in its approximate final position. From inside the firebox, reach through
the 4" hole on firebox ceiling and Slide the Vent adapter through Sock Gasket Assembly then slide this assembly through the
4" hole on firebox top. Sock Gasket must contact firebox top's outer surface.
4. From inside the Firebox, center the Vent Adapter Assembly within the 4" hole at the firebox top. NOTE: THIS IS CRITICAL. IF
NOT CENTERED, AN EXHAUST LEAK CAN OCCUR!
5. See Figure, below. Slide Adapter Bolt through U-Clamp's center hole. U-Clamp must face upward. Hold the Vent Adapter
against the firebox top. Hand thread U-Clamp Nut then tighten U-Clamp Nut using a ½" open-end wrench or a ½" deep-well
socket and ratchet. Tighten the nut enough to compress the sock gasket ½ its thickness and create a proper seal. Do not
over tighten, as doing so can permanently damage the vent adapter.
6. Reinstall the baffle in its original position and secure in place using the two hex head screws you removed earlier.
