Dvvk-4F Flex Vent Instructions - Empire Comfort Systems DVCD32FP30N-1 Owner's Manual

INSTALLATION
1. Unpack vent components and check that all items are
included.
2. Check to see that the vent spacer springs are located around
the flue 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 the flue, then interlock the ends of
each spring about 2". See Figure B. Maintain equal distance
between spring spacers.
3. Remove the 6-⅝" diameter Vent collar from the fireplace.
Replace 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.

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.
