l.
Less than 3' (0.91 m) from an inside corner of an "L"-
shaped structure;
m. So that the bottom of the vent termination opening is
less than 1' (0.30 m) above any surface that may
support ice, snow, or debris;
n. So that the flue gasses are directed toward brickwork,
siding or other construction, in such a manner that they
will be damaged from heat or condensation from flue
gasses.
CAUTION
Most codes have a notwithstanding clause which states that
products of combustion shall not enter the dwelling under
any circumstances, even if all other code requirements as to
construction and location have been complied with. The
installer is ultimately responsible to do whatever is
necessary to ensure that flue gasses do not enter the
dwelling.
* For installations in the U.S.A. refer to Section 6.7.3.4 of
the NFPA 31.

INSTALLATION OF THE COMPONENTS
Refer to Figure 2 for additional details on components
identification.
2.3.1
Installing the terminal in the wall
1. Open up a 6" (15,24 cm) hole for the VTK-53A / VTK1,
VTK-54A / VTK098 / KLAVT0101DET and VTK-64A /
VTK2 terminals and a 6¼” (15,88 cm) hole for the
VTK-
65A / VTK3 / KLAVT0201DET terminal in the wall in
accordance with the location considerations outlined in
the previous section (2.2);
2. Fasten the wall plate to the inside-wall using 4 field-
supplied fasteners, appropriate for the wall material.
Note that the pressure control bracket (item G) must be
removed to access the top right wall plate screw hole
(item E). Install the wall plate so that the top of the hole
in the wall plate is positioned 1/8" (3.2 mm) higher than
the top of the 6" (15,24 cm) hole in the wall, see Figure
3. This will ensure the proper slope of the terminal for
the proper evacuation from the inside to the outside;
3. Remove the 3 screws (item C) holding the end cone
(item A) in place and remove the cone;
4. Remove the 4 screws (item C) holding the stabiliser
shroud (item B) 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"
(5.08 cm) past the outside wall, see Figure 3;
