vent at 8" and 12" intervals along its length. See Figure A. If not,
stretch the spacer springs to about 15" long and wrap them around

this collar with the 7" diameter Flex Vent adapter collar provided
with the vent kit.
4. Slide the Flex Vent flue pipe into the Outer Flex Vent pipe.
5. Install the Wall Firestop/Thimble assembly as required through the
wall. Refer to the venting charts in the fireplace manual to determine
the proper height and size of the vent opening. The minimum
opening should be 9" wide by 11" high. The minimum combustible
clearance from the horizontal vent is 1" from sides and bottom, and
3" above the vent pipe. See Figure D.
6. In most cases, after determining the length of the vent that is
needed, it may be easier to install the flue and outer vent pipes to
the Termination Cap first, then from the outside, feed the venting
through the wall to the fireplace.
7. If the venting is to long, trim off any excess vent before attaching
the vent end connectors.
8. Attach the Termination Cap to the outside of the house.
9. Prior to making the vent connections, apply high temperature
sealant (1000 degree F min.) to the vent connections before securing
with the band clamps provided. Note: the flue pipe end without the
adapter is to be installed to the Termination Cap.
10. Apply sealant to the outside of the flue pipe adapter and connect
to the flex flue pipe. Then insert the adapter into the fireplace flue.
Secure flue adapter to the fireplace flue with a minimum of two
screws provided. See Figure C.
11. Attach the Outer Vent pipe to the 7" diameter Collar on the fireplace
with a large band clamp provided. Sealant may also be used on the
outer vent connections.
12. Check all vent connections for tightness. Make sure horizontal
venting has the proper rise and combustible clearances required.
Refer to venting charts in fireplace instruction manual.
