The
DVVK-5F FLEX VENT KIT
includes the following
components:
• (1) Horizontal Termination Cap
• (1) 4-foot section of Flex vent with spacers (5in flue/8in
outer pipe) with flue adapter collar
•
(1) Wall Firestop/Thimble Assembly
•
Hardware pack that includes band clamps and screws
Maintain at least ½inch rise for every 12 inches of vent run.
CAUTION
•
Because of sharp edges, always use gloves when
handling the flex vent components.
• Always follow the general venting requirements for
vent terminal location, vent lengths, and clearance to
combustible materials.
•
If space permits, it is generally easier to attach venting
in the top vent configuration.
•
Always stretch and secure venting with wire or metal
strapping to ensure that the horizontal runs do not
sag.
•
Vent connections should overlap a minimum of 1in for
proper sealing.
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 8in intervals along its length.
See
Figures 55 & 56.
If not, stretch the spacer springs to about
15in long and wrap them around the flue, then interlock the
ends of each spring. Maintain equal distance between spring
spacers.

3. Attach a 6in piece of hard pipe to raise the connection point
above the fireplace.
4. Use existing 8in diameter inlet collar to attach outer 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 10in wide by
12in high. The minimum combustible clearance from the
horizontal vent is 1in from sides and bottom, and 3in above
the vent pipe.
See Figure 57.
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.
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.
