VENTING CONFIGURATIONS:
HORIZONTAL TERMINATION
The shaded area on the following diagram, Fig. 6, illustrates the allowable configuration
and variations when installing venting with a horizontal termination.
Figure: 6 - Illustration of allowable horizontal venting configurations.
Example:
A 10 foot vertical rise with a 10 foot horizontal run falls within the shaded area, and
therefore, is an allowable installation.
Additionally, vent configuration consisting of a 3footminimumverticalventheightfollowed
by a 90 degree elbow, maximum 2 feet horizontal vent run, another 90 degree elbow and
another maximum of 2 feet horizontal vent run is also a tested and approved installation.

VENTING CONFIGURATIONS:
VERTICAL TERMINATION
The shaded areas of the two diagrams below illustrate the allowable venting configuration
when installing straight vertical or offset vertical venting utilising a vertical venting
termination cap.
Figure: 7 - Illustration of allowable vertical venting configurations.
Examples:
•Venting with vertical termination. A 10-foot vertical rise falls within the shaded
area, and therefore is an allowable venting configuration.
•Venting with an offset to vertical termination. A 15-foot vertical rise with a 4-foot
horizontal offset distance falls within the shaded area and is an allowable venting
configuration.
A
ll Vertical And Offset Vertical Vent Installations Require The Use Of The
SimpsonDura-VentVentRestrictor. If The Venting Is Enclosed In A Chase,
(Minimum Size Of 9” X 9”), Maintain A 1¼” Clearance To All Combustibles.
ATTENTION:
All vertical
applications must
use the HIGH WIND
TERMINAL.

KOZI DIRECT VENT GAS STOVE

PLANNING YOUR INSTALLATION
As mentioned on the previous pages, there are basically two types of Direct Vent System
installations: vertical and horizontal termination. Confirm that the desired installation is
allowed by referencing the maximum vertical riseandmaximumhorizontalrun with Figs. 6-
7.
During the process of planning your venting installation, you will be required to know the
proper vent length to select according to your specific needs. For horizontal installations,
determine the minimum clearance from the rear of the unit to the wall. Remember to take
into consideration the thickness of the wall itself. All horizontal venting must have a ¼”
rise per foot of run towards the terminal cap. Determine the amount of vertical rise
required for "vertical-to-horizontal" type installations.
When working with vertical installations, determine the length of vent pipe required by
measuring the distance from the unit flue outlet to the ceiling, the ceiling thickness, the
vertical rise in the attic or second story, andanallowancetosatisfy clearance requirements
above the roofline.
If the application calls for a two story “through the floor” installation, the use of fire stops
is mandatory at each floor level. Additional pipe and elbows will be required if an offset
is needed. Venting terminals shall not be recessed into a wall or siding.
IMPORTANT
The Gas Appliance And Venting System Must Be Vented Directly To The
Outside Of The Building, In Accordance With All Regulatory Requirements,
And Never Be Attached To A Chimney Serving A Separate Solid Fuel Or Gas
Burning Appliance. Each Direct Vent Appliance Must Use Its Own Separate
Vent System. Common Vent Systems Are Prohibited.
All Venting Installations Using Simpson Dura-Vent Direct Vent System
Model DV-GS, Must Be In Compliance With The Venting Instructions And
Requirements Specified By Simpson Dura-Vent.
Safety Precautions For The Installer:
1. Wear Gloves And Safety Glasses For Protection.
2. Exercise Extreme Caution When Using Ladders Or
Working On Roof Tops.
3. Make Yourself Aware Of The Locations Of All
Electrical Wiring Within The Walls And Ceiling.

VENT RESTRICTOR
Ventrestrictorsarerequiredincertain venting applications. This restrictormustbeinstalled
before connecting the vent pipe to vent terminal.
Referring to the figure below, slide the restrictor into the inner flue pipe and bend the side
tabs appropriately to secure the part. Examine the following diagram for further detail.
Figure: 8 - Drawing of venting restrictor and placement.
HORIZONTAL TERMINATION INSTALLATIONS
1. Set the unit in the desired location, this location must satisfy all applicable
codes and regulations. Check to determine if wall studs and roof rafters are
clear of the venting path. Adjust the unit accordingly.
2. SimpsonDura-VentDirectVentpipeand fittings aredesignedwithspecialtwist
lock connections for attaching the appliance flue outlet to the venting system.
This special twist lock adapter has been installed on the appliance from the
factory.Assemblethedesiredcombinationofpipe and elbows to theappliance
adapter with pipe seams facing towards the wall or ceiling, depending on
application.
Twist Lock Procedure
Four indentations, located on thefemaleendsofthepipes and fittings, aredesigned
to slide straight into the male ends of adjacent pipes and fittings. Align the four
indentationssothatthey matchthe four entry slots on the male ends,andthenslide
into slots. Push the pipe sections tightly together, then twist lock one section
clockwise ¼ turn, until a complete lock is achieved.

3. With the pipe attached to the stove, slide the unit into its correct location
and mark the wall for a 10" x 10" square hole. The centre of the hole
should coincide with the centreline of the horizontal incorporating the
required inclination. Cut and frame the hole in the exterior wall where
the vent will be terminated.
4. Applyathinbead of non-hardening masticaroundtheouteredgesofthe
terminal to ensure a tight seal between the Stand-off and the terminal.
Attach the Vinyl Siding Stand-off, if required, to the Horizontal Vent
Terminal. Install the vinyl siding stand-off between the vent cap and the
exterior wall and attach with the four woodscrewsprovided.Sealaround
the vinyl stand-off on all four sides. The arrow on the exterior of the vent
cap should be pointing upwards. Ensure that all clearances have been
maintained. (The four wood screws should be substituted with the
appropriate fastener particular to your buildings exterior finish.)
5. Prior to connecting the horizontal run of vent pipe to the vent terminal,
slide the decorative wall thimble cover over the pipe, and attach with
wood screws.
6. Slide the appliance and vent assembly towards the wall, carefully
inserting the vent pipe into the vent cap assembly. It is important to
insure that the vent pipe fits into the vent cap by a minimum overlap of
1-1/4 inches. Secure the connection between the vent pipe and the vent
cap by attaching the sheet metal strips extending from the vent terminal
assembly into the outer wall of the vent pipe. Use the two sheet metal
screws provided for attaching the pipe and strapping. Bend any
remaining strapping back towards the vent cap to conceal it behind the
wall thimble.
NOTE: Horizontal runs of venting must be supported every three
feet. Wall strapping kits are available for this purpose.
NOTE: The horizontal run must possess a ¼” rise per foot of run
towards the terminator. Never allow the venting to run downwards.
This situation could cause excessive temperature build up and
present the possibilit
y
of fire and safet
y
hazards.
NOTE: The venting terminal shall never be recessed into a wall or
siding. The vinyl siding standoff kit is not mandatory on all
horizontal termination installations, only when the exterior of the
buildin
g
possesses a vin
y
l sidin
g
finish.

KOZI DIRECT VENT GAS STOVE

7. Slide the decorative wall thimble up the wall surface and attach with
screws provided. Apply the decorative brass or chrome trim kits if
desired.
VERTICAL TERMINATION INSTALLATIONS
1. Insure that the 1-1/4 inch clearances have been maintained to
combustibleswhenpassingthroughceilings,walls, roofs, enclosures or
attic rafters. Do Not pack air gaps with insulation. Refer to Fig. 7 for
verification of maximum vertical rise of venting system and maximum
horizontal offset limitations.
2. Set the gas appliance in its appropriate location. Use a drop plumb line
from the ceiling to locate exactly the appliance flue exit. Mark the
location where the flue will penetrate the ceiling. Drill a pilot hole at this
location. Now drop a plumb line from the roof to the hole previously
drilled in the ceiling, and mark the spot where the vent will penetrate the
roof. To avoid having to cut any load bearing members of the roof
rafters or ceiling joists, insure they are all out of the path of the venting.
You may wish to offset the venting or relocate the appliance to
accommodate these clearances.
3. To install the Round Support Box / Wall Thimble in a flat ceiling, cut a
10 inch square hole in the ceiling centred on the hole drilled in the
previous step. Frame in the hole from the exterior surface.
4. Assemble the desired lengths of venting pipe and elbows necessary to
reach from the appliance adapter up through the Round Support Box.
Insure that all pipes and elbow connections are in the fully twist locked
position and sealed.
5. Cut a hole in the roof centred on the small drilled hole placed in the roof
during step 2. The hole should be of sufficient size to meet the minimum
requirements for clearances to combustibles. Continue to assemble the
lengths of pipes and elbows necessary to reach from the ceiling support
boxupthroughthe roofline. Galvanized pipe and elbows may be used in
the attic as well as above the roofline. The finish of galvanized pipe is
more desirable above the roofline due to its higher corrosion resistance
properties.
6. Slip the flashing over the pipe sections protruding through the roof.
Secure the base of the flashing to the roof with roofing nails. Insure the

KOZI DIRECT VENT GAS STOVE
20
roofing material overlaps the top edge of the flashing. Verify that the
minimum clearance to combustibles is maintained at the roof line. Slide
the storm collar over the pipe section and seal.
7. Continue to add pipe sections until the height of the vent cap meets the
minimum building code requirements described in the following chart,
Roof Pitch Vent Height Table. Note that for steep roof pitches, the vent
height must be increased. A poor draft, or down draft, can result from
high wind conditions, nearby trees, adjoining rooflines, steep pitched
roofs, and other similar factors. In these cases, increasing the vent
height may resolve the problem. Twist lock the vent terminal.
NOTE: If an offset is necessary in the attic to avoid obstructions, it is
important to support the vent pipe every three feet to avoid excessive
stress on the elbows. Wall strapping kits are available for this purpose.
NOTE: For multi-story vertical installations, a ceiling fire stop is
required at the second floor, and each subsequent floor thereafter.
The opening should be framed to 10” x 10” square inside
dimensions.
Any occupied areas in the first floor, including closets and storage
spaces, through which the venting passes, must be enclosed. The
enclosure may be framed and paneled with standard building
materials. DO NOT fill in any of the required air gaps with insulation.
