The DVVK-4F FLEX VENT KIT includes the following components:

 

•

(1)

•

(1) Wall Firestop/Thimble Assembly

 

pipe)

•

Hardware pack that includes band clamps and screws

•(1) 4" diameter flue adapter collar

Flex venting can only be installed vertically off of the DVX Series fireplaces. When installing a horizontal vent run from top connections, maintain at least ½" rise for every 12" of vent run. Refer to Figure 54 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.

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 42. 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 43. 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 45.

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.

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. 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 44.

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.
