10. VENT UNIT INSTALLATION

10.1
If using any optional vent extension kits #905VEK,
cut to the required sizes - see venting graph figure 1.
10.2
Identify the appliance top decorative collar. The
collars have identification labels. Remove the label.
Place the collar over the vertical section of the elbow
or vertical extension. Locate the elbow unit or vertical
extension fully over the appliance vent ducts.
10.3
If any vertical extension units are installed, locate the
elbow unit fully over the top of the extension.
10.4 Rotate the elbow until it is in direct line with the wall
opening.
10.5
If a horizontal extension is required, loosely fit a joint
masking collar (supplied with the kit) over the
extension. Fit the extension fully to the end of the
elbow. If necessary, temporarily support it.
10.6
Loosely fit the joint masking collar (supplied with the
appliance vent unit) over the free end of the
horizontal length of the vent. Loosely fit the
decorative wall collar over the horizontal length of
the vent with the central dished area projecting into
the room.
10.7
Measure the distance from the elbow or horizontal
extension to the wall allowing for the amount of
overlap where the elbow or extension enters the
terminal unit (figure 14 dimension "A").
10.8
Calculate the total length of terminal required. This
length is:- Elbow or extension to wall (figure 14
dimension "A") + Wall thickness (figure 14
5
dimension "B") + 3 /
8
Fig.14 Vent terminal length
10.9
Mark the vent terminal at the length calculated
measuring from the outside end of the vent cap.
Insert the Styrofoam support ring and push it as
close to the marked position as possible. Cut off the
vent tubes squarely at the marked position. Make
sure that all Styrofoam is removed from the vent
unit after cutting.
10.10
Fit the vent terminal unit through the wall from the
outside. Locate the inside end fully over the elbow or
horizontal extension.. Make sure that the seam on
the outer tube is not at the bottom.
" (terminal length outside wall).
10.11
Place the remaining wall plate over the outside wall
end of the terminal with the dished projection facing
inside. Push the plate up to the wall so that the
dished projection locates inside the vent shield tube
(see fig. 15). Remove any temporary wedges. If
possible while still maintaining a sound connection
to the appliance, slope the terminal very slightly
down towards the outside so that any rain will run
away from the appliance. The terminal should
never slope down into the room. This could cause
water to accumulate in the appliance.
Mark the wall plate fixing holes on the wall. Remove
the plate.

10.12
Drill the fixing holes in the wall and insert plugs if
necessary.
10.13
Replace the wall plate locating it firmly inside the
shield tube. Make sure that the slots in the terminal
end cap are outside the wall plate (see figure 15).
10.14
Line up the screw holes. Start the mounting screws.
Apply a clear silicone rubber sealant under the
edges of the wall plate and tighten the screws. Apply
a bead of silicone sealant around the vent tube
where it exits the wall plate (see figure 15).
10.15
When the terminal is properly located, secure it at
the inside wall end by drilling into the terminal outer
tube through the holes in the two vent securing
brackets and securing with two #6 tapping screws
provided. Make sure that the drill does not
penetrate the inner vent tube.
10.16 Remove the backing paper from the adhesive pads
on the wall plate vent securing brackets. Push the
decorative wall collar firmly inside the dished center
of the wall plate onto the adhesive pads (see fig.
16).
