DVVK-4F FLEX VENT INSTRUCTIONS
The
DVVK-4F FLEX VENT KIT
includes the following compo-
nents:
• Horizontal Termination Cap
• 4-foot section of Flex vent with spacers (4” flue/7” outer pipe)
• 4” diameter Flue adapter collar
• 7” diameter Outer Vent adapter collar
• Wall Firestop/Thimble Assembly
• Hardware pack that includes band clamps and screws
Flex venting can be installed either vertically or horizontally off
of the DVP36 Series fireplaces. When installing a horizontal
vent run from top connections, maintain at least ½” rise for
every 12” of vent run. When venting horizontal off the rear
vent connections, allow a minimum rise of 2”. Refer to Figure
57 when mounting termination near vinyl siding.
CAUTION: Always stretch and secure venting with wire or
metal strapping to ensure that the horizontal runs do not sag.
If space permits, it is generally easier to attach venting in the top
vent configuration.
Because of sharp edges, always use gloves when handling the
flex vent components.
Vent connections should overlap a minimum of 1” for proper
sealing.
Always follow the general venting requirements for vent terminal
location, vent lengths, and clearance to combustible materials.
STEP-BY-STEP 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 C.
Figure C
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.
CAUTION: Do not use force when installing the Horizontal
Vent Termination into the flex venting. Always stretch venting
out first, then cut off excessive vent material prior to sliding
the vent termination into the flue and inlet venting. Forcing
the termination cap into the flex venting will deform the flue
venting, which will restrict the exhaust gases, and cause
improper operation of the fireplace.
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.
NOTICE
: 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 D.
Figure D
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.
