8. INSTALLATIONS WITH HORIZONTAL TERMINATION – INSTALLING
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.
See section 4 for full range of horizontal termination applications.
8.1. 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 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 then
the wall plates or thimbles will not be required.
If the wall has combustible material, mark the wall for a 10"x10"
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 centerline of the horizontal vent. (see
figure 24)
8.2. 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 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
4 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 4 screws provided.
See figure 24.
