Dvvk-5F Flex Vent Instructions - Empire Comfort Systems DVP42DP31N-2 Installation Instructions And Owner's Manual

The DVVK-5F FLEX VENT KIT includes the following compo-
nents:
• Horizontal Termination Cap
• 4-foot section of Flex vent with spacers (5" flue/8" outer pipe)
with flue 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 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 47 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 ter-
minal 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" intervals along its length. See
Figure 53. 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 52. Maintain equal
distance between spring spacers.

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 55.
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.
8. 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.
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 54.
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.
