TABLE 3
Minimum clearances of side-wall vents
Models OHB6, OLB6, OLR160, and OUF160
PORTION OF VENT
Vent pipe, up to vent terminal*
Vent terminal
*Do not enclose venting.
Installation considerations - DV-2000™
Select a location for the vent terminal in accordance with all local
and national codes. The following shall be considered as
minimum requirements that can be overridden by stricter local
and national codes.
The vent shall not terminate
a.
Directly above a paved sidewalk or paved driveway that is
located between two buildings, and that serves both
buildings;
b.
Less than 2 m (7') above any paved driveway;
c.
Within 1.8 m (6') (in Canada) of a window or door, or
mechanical air supply inlet to any building;*
d.
Within 1.8 m (6') (in Canada) from the soffit of the roof of the
structure;*
e.
Above a gas meter/regulator assembly or at least 0.9 m (3')
from the vertical centreline of the regulator;
f.
Within 1.8 m (6') of any gas service regulator vent outlet, or
within 0.9 m (3') of an oil tank vent, or an oil fill inlet;
g.
Less than 0.3 m (1') above ground level;
h.
Within 1.8 m (6') of any other combustion air inlet;
i.
Within 1.8 m (6') of a property line;
j.
Underneath a veranda, porch or deck;
k.
So that the flue gases are directed at combustible material
or any openings of surrounding buildings that are within
1.8 m (6');
l.
Less than 0.9 m (3') from an inside corner of an "L"-shaped
structure;
m.
So that the bottom of the vent termination opening is less
than 0.3 m (1') above any surface that may support ice,
snow, or debris;
n.
So that the flue gases are directed toward brickwork, siding
or other construction, in such a manner that may cause
damage from heat or condensation from flue gases.
*For installations in the U.S.A. refer to Section 6.7.3.4 of the
NFPA 31.
CAUTION
Most codes have a notwithstanding clause that
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.

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.
DNS-0623 Rev. A
WARNING
Do not enclose the vent pipe in a ceiling or combustible
structure.
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 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 15 cm (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 30 cm
(12") from the end of the vent (see Figure 1.3).
