INSTALLATIONS WITH HORIZONTAL TERMINATION – INSTALLING
TO WALL
See section 4 for full range of horizontal termination applications.
8.1.
Wall Opening
Fit all the required Dura-vent DV GS pipes and elbows up to the wall to check the wall
opening position. See the Dura-vent 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 Dura-vent
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.
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.
8.3.
Dura-vent Terminals – Installing to wall
Unless the wall is totally non-combustible, fit Dura-vent wall thimbles
#942.
Install as detailed in the Dura-vent instructions supplied with the pipes.
