DVVK-4F FLEX VENT INSTRUCTIONS
The
DVVK-4F FLEX VENT KIT
includes the following compo-
nents:
1 - Horizontal Termination Cap
1 - 4-foot section of Flex vent with spacers (4-in flue/7-in outer
pipe)
1 - 4-in diameter flue adapter collar
1 - 7-in diameter outer vent adapter collar
1 - Wall Firestop/Thimble Assembly
Hardware pack that includes band clamps and screws
NOTE: If installing the DVVK-4F Flex Vent Kit, an SD46DVA-
FCFX7 Flex Adaptor Collar Assembly must also be used
(purchased separately).
When installing a horizontal vent run from top connections,
maintain at least ½-in rise for every 12-in of vent run.
CAUTION
Always stretch and secure venting with wire or metal strapping
to ensure that the horizontal runs do not sag.
Because of sharp edges, always use gloves when handling the
flex vent components.
Vent connections should overlap a minimum of 1-in for proper
sealing.
Always follow the general venting requirements for vent
termination 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-in and 12-in intervals along its length.
See
Figure 63.
If not, stretch the spacer springs to about 15-in
long and wrap them around the flue, then interlock the ends
of each spring about 2-in.
See Figure 64.
Maintain equal
distance between spring spacers.
