Installations with Horizontal Termination—Installing to Wall
Important Installer Notice – Weather Sealing & Vapor Barriers
It is the installer’s responsibility to ensure that vent installations through exterior walls are
caulked and weatherproofed in such a manner as to:
• Prevent rain water from entering the wall from the weather side by adequately caulking the
outer vent plate to the exterior wall surface.
• Prevent moisture inside the home from penetrating into the wall structure by ensuring the
inside wall plate is adequately sealed to the inside vapor barrier.
• Prevent rain water and moisture from entering the walls by sealing the joints between the
outer vent tube and the inner and outer wall plates.
We recommend the use of a high quality polyurethane sealant.

section for full range of horizontal termination
applications.
Wall Opening
• Fit all the required pipes and elbows up to the wall to check
the wall opening position. See the manufacturer’s instructions
supplied with the venting sections.
• Make wall opening.
If the wall is constructed of solid non-combustible materials and
has no combustible surface cladding (including wood) inside or
outside, the wall plates or thimbles will not be required.
If the wall has combustible material, mark the wall for a 10” x
10” square. If the wall is totally non-combustible (e.g. masonry
block or concrete), mark for a 7” circular hole. In both cases,
the center of the hole should line up with the center line of the
horizontal vent.
Valor Terminal #551DVK—Preparing Wall Plates
The wall plates are not used for 7” hole in non-combustible walls.
1. Bend the wall shields and screw to the inside of the wall plates
with 6 thread-cutting screws per plate. See figure 22.
2. Bend the inner wall plate tab as shown in figure 23 so that the
seam on the terminal tube will pass clearly through the plate
with the wall shield at the top. Place the inner wall plate over
the terminal unit.
3. Slide the appliance/terminal into the wall. Make sure that the
drain hole is at the bottom—the seam will be through the notch
in the wall plates. See figure 24.
4. Slide the inner wall plate up to the wall. Mark the four holes for
the wall screws. Slide the plate away.
5. Drill and plug the wall.
6. Screw the plate to the wall with four screws provided.
7. Bend the outer wall plate tab as shown in figure 23.
8. Place the outer wall plate over the terminal unit. Slide the wall
plate up to the wall. Mark the four holes for the wall screws.
Slide the plate away.
9. Drill and plug the wall.
10. Screw the plate to the wall with four screws provided. See
figure 24.
