12
equally spaced around the circumference of the
stainless steel core, starting with the first screw at
top dead center. Start the drill point of the screws in
the valleys of the corrugations at 3/8”-5/8” back
from the end of the stainless steel core.
6. With the stainless steel core now firmly attached to
the terminal, tear off the other green gum-sealing
strip from the backing strip. Wrap the seal strip
around the joint, always keeping the centerline of
the seal strip over the line where the corrugated
stainless steel core makes the transition to the
smooth outer surface of the terminal pipe. After
wrapping the seal strip around once, allow 1/2”
overlap and tear off the residual length.
7. Break the residual length of seal strip in to 3 equal
parts and stuff them onto the screw heads of the
stainless steel self-drilling screws so that the screw
heads are completely covered.
8. Position the other stainless steel band clamp over
the gum seal joint so that the edge of the clamp
closest to the terminal lines up with the edge of the
gum seal that is closest to the terminal. Tighten the
band clamp with considerable torque to cause the
gum seal be squeezed into all crevices and to ooze
out of the end of the clamp closest to the terminal
(see figure #1.11).
9. The seal is permanent and should never need to be
disconnected as the end of the terminal can be
opened for cleaning and inspection by removing the
screened end-cone assembly. Tuck the vent
insulation into the recess in the terminal body.
10. Screw the spin sleeve tightly into the recess for a
finished appearance. Wrap the other end of the
spin sleeve with aluminium tape to cover any metal
burrs that may be present (see figure #1.12).
11. Bend the venting into the desired radius coming off
the terminal.
Installing terminal in the wall - DV-2000™:
1. Cut a 6” hole in the side-wall in accordance with the
location considerations outlined in the previous
section.
2. Fasten the wall plate to the inside-wall using 4 field-
provided fasteners appropriate for the material
behind the wall plate. Depending on the angle of
access, the pressure control bracket may need to
be removed to access the top right wall plate screw
hole. For concrete and block, Tapcon™ screws or
equivalent are recommended. Install the wall plate
so that the top of the hole in the wall plate is
positioned 1/8” lower than the top of the 6” hole in
the wall. This will accommodate the proper
downward slope of the terminal, in the direction
from the inside to the outside.
3. Remove the 2 screws fastening the end cone in
place and remove the cone.
4. Remove the 2 screws fastening the stabiliser
shroud in place and remove the stabiliser shroud.
5. Insert the main body of the terminal through the wall
plate so that the end of the terminal extends about
2” past the outside wall.
6. Install the stabiliser shroud and replace the two
mounting screws. (see figure #1.13).
7. For concrete and block wall installations in
particular, If it appears that the flange on the back
of the stabiliser shroud is not large enough to cover
the irregularities in the hole, a field fabricated wall
plate can be constructed out of 304, 316, or 316L
stainless steel.
8. Silicone seal the circumference of the joint where
the stabiliser shroud connects to the main body of
the terminal.
9. Apply caulking to the back plate of the stabiliser
shroud and push the terminal back firmly against
the wall.
10. While pushing down gently on the top of the
stabiliser shroud, install the 3 stainless steel 2”
screws provided with the kit to secure the back of
the shroud to the wall. Do not overtighten the
screws or it will distort the stabiliser shroud. The
screws will not be necessary in a concrete or block
wall as the mortar can provide positive positioning.
11. Tighten the clamp on the wall plate to secure the
terminal in position.
12. Apply more caulking all around the seam where the
stabiliser shroud meets the wall. It is important to
have a good seal to prevent water from entering the
dwelling (see figure #1.14). A considerable amount
of caulking may be necessary for irregular wall
surfaces such as lapped siding.
13. Install the end cone and replace the two mounting
screws.
14. Support the vent and intake air piping so that a 1/4”
to 1/2” downward slope (toward the outside) results
for proper drainage out the terminal body.
