DVVK-5F FLEX VENT INSTRUCTIONS
The
DVVK-5F FLEX VENT KIT
includes the following components:
• (1) Horizontal Termination Cap
• (1) 4-foot section of Flex vent with spacers (5” flue/8” outer
pipe) with flue adapter collar
•
(1) Wall Firestop/Thimble Assembly
•
Hardware pack that includes band clamps and screws
Flex venting can be installed either vertically or horizontally
off of the DVP 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 the
Figure 53 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 han
-
dling 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.
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 64.
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 65.
Maintain equal distance
between spring spacers.
Figure 64
Figure 65
3. Use existing 8” diameter inlet collar to attach outer vent pipe.
4. 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 10” wide by 12”
high. The minimum combustible clearance from the horizontal
vent is 1” from sides and bottom, and 3” above the vent pipe.
See Figure 67.
5. 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.
6. If the venting is to long, trim off any excess vent before
attaching the vent end connectors.
7. 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.
8. Prior to making the vent connections, apply high temperature
sealant (600 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.
9. 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 66.
10. Attach the Outer Vent pipe to the 8” diameter collar on the
fireplace with a large band clamp provided. Sealant may also
be used on the outer vent connections.
11. 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.
