Insulated flexible venting - DV-2000TM:
The certified venting materials come in 3 lengths, Model
No. tFV3-15, 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
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:
5 feet minimum 30 feet maximum
Poison carbon monoxide gas hazard
Even though the flexible venting is insulated, it
cannot be run through an unheated space.
To do so could cause residual condensation
inside the stainless steel liner, which may
eventually perforate the liner and allow vent
gasses to enter the dwelling.

*Do not enclose venting
Installation considerations - DV-2000TM:
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 of a window or door, or mechanical air
supply inlet to any building, including soffit
openings;
d. above a gas meter/regulator assembly within 3 feet
of a vertical centerline of the regulator;
e. within 6 feet of any gas service regulator vent
outlet, or within 3 feet of an oil tank vent, or an oil fill
inlet;
f. within less than 1 foot above ground level;
g. 6 feet of any other combustion air inlet;
h. within 6 feet of a property line;
i. underneath a veranda, porch or deck;
j. so that the flue gases are directed at combustible
material or any openings of surrounding buildings
that are within 6 feet;
k. less than 3 feet from an inside corner of an L-
shaped structure;
I. so that the bottom of the vent termination opening is
less than 1 foot above any surface that may support
ice, snow, or debris;
m. 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.
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.
Installation of side-wall venting - DV-2000TM:
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.
