Flue Pipe Sizing; Insulated Flexible Venting - Dv-2000 - ICP OLR105A12D Installation Instructions Manual

CAUTION
When the furnace (chimney installation) is vented
together with other combustion appliances such as a
water heater, the allowable venting materials for use
with those appliances must be investigated ("L"-vent,
etc.).

Flue pipe sizing

The following table is an excerpt from the Installation Code
and indicates the permitted flue sizes and minimum base
temperatures for circular flues in chimneys with a thermal
resistance of less than R6 (6 ft
appliance, burner, or chimney is installed, chimney vent sizes
and maximum flue gas temperatures shall comply with Table
2 (measured at the chimney connector with the barometric
damper shut, after 5 minutes of operation).
Note: Thermal resistance values for typical chimneys are as
follows:
2 •hr •°F / Btu):
R2 (2 ft Clay-lined masonry, A-vent
2 •hr •°F / Btu):
R3 (3 ft Metal liner in clay-lined
Masonry
2 •hr •°F / Btu):
R6 (6 ft Metal or clay-lined masonry
with R4.5 (4.5 ft
insulation between liner and
masonry (e.g. 2" of expanded
mica or 1 3/8" of high density
glass fibreboard.)
Applying Table 2
If a furnace with a 0.60 USGPH nozzle is to be connected to a
6.1 m (20') tall clay-lined masonry chimney, the thermal
resistance of this type of chimney is R2, (which is less than
R6). The actual firing rate at 156 psig is 1.25 x .60 = .75
USGPH. Therefore this table shall apply as follows:
The minimum size permitted shall be 10.16 cm (4") in. inside
diameter;
The maximum size permitted shall be 12.70 cm (5") inside
diameter;
The minimum base temperature shall be about 160°C
(320°F).
1.4.3 Side-wall venting - DV-2000™
Direct Vent System
The furnace can be side-wall vented, without the use of a
side-wall power vent, with the high static pressure Beckett
AFII and Riello 40-BF oil burners. Outdoor combustion air
must be directly connected to the burner or the DV-
2000™ venting system will not function.

The notable characteristics of the DV-2000™ system are as
follows:
a) Certified to use the following materials for ducting the
intake air from the terminal to the burner: Schedule 40
PVC DWV, Schedule 40 ABS DWV, and ASTM 2729
sewer Pipe;
One hole of minimal size 15.24 cm (6") is required to be
b)
cut into the side-wall, and the terminal is designed to fit
through a minimum 2 x 8 joist space;
Incorporates a vent blockage safety shutdown system. If
c)
the vent or intake opening ever becomes partially or fully
blocked, the burner will shut down before a #1 smoke
condition occurs;
d) The intake and vent circuits within the terminal can be
accessed for cleaning.
There are 3 main components to the DV-2000™ system; the
vent terminal kit VTK-1 (for models OLF/R105, OUF105,
NOUF105 and NOLF105) or VTK-2 (for models OLR160,
OUF160) and the insulated flexible venting material IFV3 (for
models OLF/R105, OUF105, NOUF105, NOLF105) or IFV4
(for models OLR160, OUF160) and the field-supplied 3" PVC
or ABS intake piping.
Poisonous carbon monoxide gas hazard.
Even though the flexible venting is insulated, it
must not be run through an unheated space.
To do so can cause residual condensation inside
the stainless steel liner. This may eventually
perforate the liner and allow vent gasses to enter
the dwelling, which can result in death, personal
injury and/or property damage.

Insulated flexible venting - DV-2000™

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 correspond to 15, 23 and 30' of 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:
1.5 m (5') minimum
