Side wall venting installation - DV-2000™
WARNING
Cuts and abrasion hazard.
Always wear protective gloves and eye protection
when handling the vent material.
The process of cutting and fitting the flexible
venting material exposes the installer to sharp
edges that could cause severe cuts to the skin.
Connection to the furnace breach - DV-2000™
1.
Remove the standard breach plate by removing the brass nuts;
2.
Determine which direction the venting will be routed from the
furnace and then install the special side-wall venting breach plate
provided in the VTK Series vent kit so that the breach plate test
port will be accessible after vent installation. However, do not
install the breach plate with the test port pointing downward.
Tighten the brass nuts;
3.
The flexible venting has 4 pieces of corrugated spin sleeve that
has been temporarily screwed on over top of it. Remove the spin
sleeve completely by unscrewing it in a counter-clockwise
direction;
4.
Using tin snips, cut the aluminium outer sleeve back by 127.0
mm (5") on the IFV Series vent (see Figure 1.1). Ensure the
snips are well adjusted and sharp or the cut end of the venting
will be too jagged to start the threads of the spin sleeve (see
Figure 1.1);
5.
Prepare the furnace breach end of the insulated flex vent by first
screwing the spin sleeve onto the corrugated aluminium jacket
(see Figure 1.2) until the trailing edge of the spin sleeve is about
0.3 m (12") from the end of the vent (see Figure 1.3);
6.
Pull the insulation back to expose the corrugated stainless steel
core;
7.
Cut the corrugated stainless steel core back by 76.2 mm (3") on
the IFV Series vent. You should now have about 76.2 mm (3") of
insulation hanging out past the stainless steel core (see Figure
1.4);
8.
Push the stainless steel core onto the breach pipe as far as it will
go (see Figure 1.5) and mechanically attach the vent to the
breach 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 at top dead centre. Start the drill point of the
screws in the valleys of the corrugations at 9.5 mm –15.8 mm
(3/8"-5/8") back from the end of the stainless steel core, so the
screw heads can be properly sealed in the forthcoming
operations (see Figure 1.6);
9.
With the stainless steel core now firmly attached to the breach,
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 breach
pipe. In other words, the seal strip must be centred over the joint.
After wrapping the seal strip around once, allow 12.7 mm (1/2")
overlap and tear off the residual length (see Figure 1.7);
10. Break the residual length of seal strip into 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
11. 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 breach lines up
with the edge of the gum seal that is closest to the breach.
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 breach (see Figure 1.9).
The gum will eventually become rubbery;
12. The seal is permanent and should never need to be
disconnected as the breach plate can be removed for cleaning
and inspection using the 4-bolt joint;
13. Tuck the vent insulation into the breach collar;
14. Screw the spin sleeve tightly into the breach 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);
15. Bend the venting into the desired radius coming off the breach.
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 254.0 mm (10")
from the end of the vent;
2.
Using sharp tin snips, cut the aluminium outer sleeve back by
127.0 mm (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 76.2 mm (3") on
the IFV Series vent. You should now have about 76.2 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 at top dead centre. Start the drill point
of the screws in the valleys of the corrugations at 9.5 mm-15.8
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
12.7 mm (1/2") overlap and tear off the residual length;
7.
Break the residual length of seal strip into 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 to 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.
