7. Pull the insulation back to expose the corrugated
stainless steel core.
8. Cut the corrugated stainless steel core back by 7.6
cm (3") on the IFV Series vent. You should now have
about 7.6 cm (3") of insulation hanging out past the
stainless steel core (see Figure 1.4);
9. Push the stainless steel core onto the breech pipe as
far as it will go (see Figure 1.5) and mechanically
attach the vent to the breech using three of the #8 x
1/2" self-drilling screws provided with the VTK Series
kit. The screws should be equally spaced around the
circumference of the stainless steel core, starting
with the first screw in the centre at the top. Start the
drill point of the screws in the valleys of the
corrugations 9-16 mm (3/8"-5/8") back from the end
of the stainless steel core, so the screw heads can
be properly sealed in the following operations (see
Figure 1.6);
10. With the stainless steel core now firmly attached to
the breech, tear off one green gum-sealing strip from
the backing. Wrap the seal strip around the joint,
always keeping the centreline of the seal strip over
the line where the corrugated stainless steel core
makes the transition to the smooth outer surface of
the breech pipe. In other words, the seal strip must
be centred over the joint. After wrapping the seal
strip around once, allow a 12 mm (1/2") overlap and
tear off the residual length (see Figure 1.7);
11. Break the residual length of seal strip in to 3 equal
parts and stick them onto the heads of the stainless
steel self-drilling screws so that they are completely
covered;
12. Two stainless steel band clamps are provided in the
VTK Series kits. Position one stainless steel band
clamp over the gum seal joint so that the edge of the
clamp closest to the breech lines up with the edge of
the gum seal that is closest to the breech.
Ensure
that the band will close with an action of one strip
sliding over the other - not under the gear head of the
draw clamp (see Figure 1.8). Tighten the band clamp
with considerable torque to cause the gum seal to be
squeezed into all crevices and to ooze out of the end
of the clamp closest to the breech (see Figure 1.9).
The gum will eventually become rubbery;
13. The seal is permanent and should never need to be
disconnected as the breech plate can be removed for
cleaning and inspection using the 4-bolt joint;
14. Tuck the vent insulation into the breech collar;
15. Screw the spin sleeve tightly into the breech collar
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 1.10);
Connection to the vent terminal - DV-2000™
1. Prepare the terminal end of the insulated flex vent by
first screwing the spin sleeve onto the corrugated
aluminium jacket until the trailing edge of the spin
sleeve is about 0.25 m (10") from the end of the
vent;
2. Using sharp tin snips, cut the aluminium outer sleeve
back by 0.13 m (5") on the IFV Series vent;
3. Pull the insulation back to expose the corrugated stainless
steel core;
4. Cut the corrugated stainless steel core back by 76 mm (3") on
the IFV Series vent. You should now have about 76 mm (3")
of insulation hanging out past the stainless steel core;
5. Push the stainless steel core onto the pipe on the back of the
terminal as far as it will go and mechanically attach the vent to
the terminal using three of the #8 x 1/2" self-drilling screws
provided with the VTK Series kit. The screws should be
equally spaced around the circumference of the stainless steel
core, starting with the first screw in the centre at the top. Start
the drill point of the screws in the valleys of the corrugations 9-
16 mm (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. Wrap the seal strip around the joint, always keeping
the centreline 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 a 12 mm (1/2") overlap and tear
off the residual length;
7. Break the residual length of seal strip in to 3 equal parts and
stick them onto the heads of the stainless steel self-drilling
screws so that they 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 0.15 m (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 3 mm (1/8") lower
than the top of the 0.15 m (6") hole in the wall. This will
accommodate the proper 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;
