Vertical runs of this system which pass through ceilings require the use of ONE (1) ceiling firestop at the hole in each ceiling through which the vent passes.

Position a plumb bob directly over the center of the vertical vent component and mark the ceiling to establish the center point of the vent. Drill a hole or drive a nail through this center point and check the floor above for any obstructions such as wiring or plumbing runs. Reposition the appliance and vent system, if necessary, to accommodate ceiling joists and/or obstructions.

Cut an appropriate sized hole through the ceiling, using the center point previously marked. See Figure 51. Frame the hole with framing lumber the same size as the ceiling joists.See Figure 51.

If the area above the ceiling is NOT an attic, position and secure the ceiling firestop on the ceiling side of the previously cut and framed hole. See Figure 52. If the area above the ceiling is an attic, position and secure the firestop on top of the previously framed hole.See Figure 53.

NOTE: Remove insulation from the framed area in the attic before installing the firestop and/or vent pipes.

HORIZONTAL TERMINATION

NOTE: Termination cap should pass through the wall firestop from the exterior of the building. Adjust the termination cap to its final exterior position on the building.

Warning: Termination cap must be positioned so that arrow is pointing up.

Attach the termination cap with the four wood screws provided. Before attachment of the termination, run a bead of silicone sealant rated above 250°F on its outside edge too, so as to make a seal to the exterior wall.

NOTE: Woodscrewscanandshouldbereplacedwithappropriate fasteners for use on stucco, brick, concrete or other types of siding.

CAUTION: If exterior walls are finished with vinyl siding, (or materials that could become discolored or warp) it is necessary to install a vinyl siding standoff.

The vinyl siding standoff will be installed between the vent terminationandtheexteriorwall.SeeFigure54.Thishorizontalvent terminationboltsontotheflatportionofthevinylsidingstandoff,so an air space will exist between the wall and the termination cap.

DVVK-5FFLEX VENT INSTRUCTIONS

The DVVK-5F FLEX VENT KIT includes the following components:

 

(1)

Horizontal Termination Cap

(1) Wall Firestop/ThimbleAssembly

(1)

4-footsection of Flex vent with spacers (5" flue/8"

Hardware pack that includes band clamps and screws

 

outer pipe) with 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 the 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 55. If not,stretchthespacerspringstoabout15"longandwrapthem around the flue, then interlock the ends of each spring about 2".

See Figure 56. Maintain equal distance between spring spacers.

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. 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 57.

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.

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 minimumopeningshouldbe10"wideby12"high.Theminimum combustible clearance from the horizontal vent is 1" from sides and bottom, and 3" above the vent pipe. See Figure 56.

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.

VERTICAL TERMINATION

Locate and mark the center point of the venting pipe. Using a nail on the underside of the roof and drive this nail through this center point. Make the outline of the roof hole around this center point.

NOTE: Size of the roof hole dimensions depend on the pitch of the roof. There must be a 1 inch clearance (25 mm) to the vertical pipe sections. This clearance is to all combustible material.

Cover the opening of the vent pipe and cut and frame the roof hole. Use framing lumber the same size as the roof rafters and install the frame securely. Flashing anchored to frame must withstand high winds. The storm collar is placed over this joint to make a water- tightseal.Non-hardeningsealantshouldbeusedtocompletelysealthis flashing installation.

Determining Minimum Vent Height Above the Roof.

WARNING: Major U.S. building codes specify minimum chimney and/or vent height above the roof top. These minimum heights are necessary in the interest of safety. These specifications are summarized in Figure 59.

Note that for steep roof pitches, the vent height must be increased.

In high wind conditions, nearby trees, adjoining roof lines, steep pitched roofs, and other similar factors can result in poor draft, or down-drafting.In these cases, increasing the vent height may solve this problem.

Figure 60

When terminating the vent cap near an exterior wall or overhang, maintain minimum clearances as shown in Figure 60.

General Maintenance

Conduct an inspection of the venting system semi-annually.

Recommended areas to inspect are as follows:

1.Check areas of the venting system which are exposed to the elements for corrosion. These will appear as rust spots or streaks and, in extreme cases, holes. These components should immediately be replaced.

2.Remove the cap and shine a flashlight down the vent. Remove any bird nests or other foreign material.

3.Check for evidence of excessive condensate, such as water droplets forming in the inner liner and subsequently dripping out at joints. Condensate can cause corrosion of caps, pipe and fittings.Itmaybecausedbyhavingexcessivelateralruns,too many elbows and exterior portions of the system being exposed to cold weather.

4.Inspectjointstoverifythatnopipesectionsorfittingshavebeen disturbed and, consequently, loosened.Also, check mechanical supports, such as wall straps or plumbers’tape for rigidity.

Venting terminal shall not be recessed into a wall or siding.

Aremovable panel or other means must be provided in the enclosure for visual inspection of the flue connection.

NOTE: This also pertains to vertical vent systems installed on the outside of the building.

Slide the vertical vent cap over the ends of the vent pipe and secure.

See Figure 61.

Installing the Vent System in a Chase

A chase is a vertical box-likestructure built to enclose the gas appliance and/or it’s vent system.Vertical vent runs on the outside of a building may be, but are not required to be installed inside a chase.

CAUTION: Treatment of firestop spacers and construction of the chase may vary with the type of building. These instructions are not substitutes for the requirements of local building codes. Therefore, your local building codes must be checked to determine the requirements for these steps.

NOTE: When installing this vent system in a chase, it is always good building practice to insulate the chase as you would the outside walls of your home. This is especially important for cold climate installations. Upon completion of building your chase framing, install the vent system by following the instructions in this manual. Remember to build the chase large enough so that minimum clearance of combustible materials (including insulation) to the vent system are maintained.

Reassembly and Resealing Vent Pipe System

Attach vent pipe to inlet and outlet vent adaptor on fireplace, replace horizontal and vertical pipe lengths, elbows and horizontal or vertical termination kit.

All vent system components lock into place by sliding the concentric pipe section with four (4) equally spaced interior beads onto the appliance collar or previously installed component end with four

(4) equally spaced indented sections. When the internal beads of each starting outer pipe line up, rotate pipe section clockwise 90° (approximately 3 inches). The vent pipe is now locked together.

Continuereplacingcomponentspertheventsystemconfiguration. Be certain that each succeeding vent component is securely fitted and locked into the preceding component in the vent system.
