Insulatedflexible venting - DV-2000TM:
steel corrugated flexible liner surrounded by a thick insulation blanket
and covered with an outer layer of flexible corrugated aluminium
sleeve to protect the insulation. Splicing vent lengths together is
prohibited. The maximum and minimum continuous vent lengths
permitted for installation are:
The certified venting materials come in 3 lengths, Model No. IFV3-15,
IFV3-23 and IFV3-30 (or IFV4-15, IFV4-23 and IFV4-30 for 160
models) are corresponding to 15', 23' and 30' continuous lengths of
vent. The vent construction is coaxial and incorporates a stainless
5 feet minimum 30 feet maximum

Installation considerations - DV'2000TM:
Installation of side-wall venting - DV-2OOOTM:
Select a location for the vent terminal in accordance with all local and
national codes. The following requirements shall be considered to be
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 7 feet above any paved driveway;
c. within 6 feet (in Canada) or 4 feet (in United States) of a window
or door, or mechanical air supply inlet to any building;
d. within 6 feet (in Canada) or 1 foot (in United States) from the
soffit of the roof of the structure.
e. above a gas meter/regulator assembly within 3 feet of a vertical
centerline of the regulator;
f. within 6 feet of any gas service regulator vent outlet, or within 3
feet of an oil tank vent, or an oil fill inlet;
g. within less than 1 foot above ground level;
h. 6 feet of any other combustion air inlet;
i. within 6 feet 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 6 feet;
I. less than 3 feet from an inside corner of an L-shaped structure;
m. so that the bottom of the vent termination opening is less than 1
foot 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.
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 breech - DV'2000TM:
1. Remove the standard breech 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 breech plate
provided in the VTK Series vent kit so that the breech plate test
port will be accessible after vent installation. However, do not
install the breech plate with the test port pointing downward.
Tighten the brass nuts.
3,
The flexible venting has 4 pieces of corrugated spin sleeving that
has been temporarily screwed on over top of it. Remove the spin
sleeving completely by unscrewing it in a counter-clockwise
direction.
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.
4,
5,
Using tin snips, cut the aluminium outer sleeve back by 5" for the
IFV Series vent (see figure #1.1). Ensure the snips are well
Ajusted 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).
Prepare the furnace breech 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
12" from the end of the vent (see figure #1.3).
