WARNING
CARBON MONOXIDE POISONING HAZARD
Failure to follow the steps outlined below for each appliance
connected to the venting system being placed into operation
could result in carbon monoxide poisoning or death.
The following steps shall be followed for each appliance
connected to the venting system being placed into operation,
while all other appliances connected to the venting system
are not in operation:
1. Seal any unused openings in the venting system.
2. Inspect the venting system for proper size and horizontal
pitch, as required in the National Fuel Gas Code ANSI
Z223.1/NFPA 54 or the National Gas and Propane
Installation Code CSA B149.1 and these instructions.
Determine that there is no blockage or restriction,
leakage, corrosion and other deciencies which could
cause an unsafe condition.
3. As far as practical, close all building doors and
windows and all doors between the space in which
the appliance(s) connected to the venting system are
located and other spaces of the building.
4. Close replace dampers.
5. Turn on clothes dryers and any appliance not connected
to the venting system. Turn on any exhaust fans, such
as range hoods and bathroom exhausts, so they are
operating at maximum speed. Do not operate a summer
exhaust fan.
6. Follow the lighting instructions. Place the appliance
being inspected into operation. Adjust the thermostat
so appliance is operating continuously.
7. Test for spillage from draft hood equipped appliances

SAFETY INFORMATION FOR USERS OF PROPANE GAS
Propane is a ammable gas which can cause res and
explosions. In its natural state, propane is odorless and
colorless. You may not know all the following safety precau-
tions which can protect both you and your family from an ac-
cident. Read them carefully now, then review them point by
point with the members of your household. Someday when
there may not be a minute to lose, everyone's safety will
depend on knowing exactly what to do. If, after reading the
following information, you feel you still need more informa-
tion, please contact your gas supplier.
PROPANE GAS WARNING ODOR
If a gas leak happens, you should be able to smell the gas
because of the odorant put in the Propane Gas.
That's your signal to go into immediate action!
• Do not operate electric switches, light matches, use your
phone. Do not do anything that could ignite the gas.
• Get everyone out of the building, vehicle, trailer, or area. Do
that IMMEDIATELY.
• Close all gas tank or cylinder supply valves.
• Propane Gas is heavier than air and may settle in low areas
such as basements. When you have reason to suspect a gas
leak, keep out of basements and other low areas. Stay out
until reghters declare them to be safe.
• Use your neighbor's phone and call a trained Propane Gas
service person and the re department. Even though you may
not continue to smell gas, do not turn on the gas again. Do
not re-enter the building, vehicle, trailer, or area.
• Finally, let the service man and reghters check for escaped
gas. Have them air out the area before you return. Properly
trained Propane Gas service people should repair the leak,
then check and relight the gas appliance for you.
NO ODOR DETECTED - ODOR FADE
Some people cannot smell well. Some people cannot smell
the odor of the chemical put into the gas. You must nd
out if you can smell the odorant in propane. Smoking can
decrease your ability to smell. Being around an odor for a time
can affect your sensitivity or ability to detect that odor. Sometimes
other odors in the area mask the gas odor. People may not smell
the gas odor or their minds are on something else. Thinking
about smelling a gas odor can make it easier to smell.
The odorant in Propane Gas is colorless, and it can fade
under some circumstances. For example, if there is an under-
ground leak, the movement of the gas through soil can lter the
odorant. Odorants in Propane Gas also are subject to oxidation.
This fading can occur if there is rust inside the storage tank or in
iron gas pipes.
The odorant in escaped gas can adsorb or absorb onto or into
walls, masonry and other materials and fabrics in a room. That
will take some of the odorant out of the gas, reducing its odor
intensity.
Propane Gas may stratify in a closed area, and the odor intensity
could vary at different levels. Since it is heavier than air, there
may be more odor at lower levels. Always be sensitive to the
slightest gas odor. If you detect any odor, treat it as a serious
leak. Immediately go into action as instructed earlier.
SOME POINTS TO REMEMBER
• Learn to recognize the odor of Propane Gas. Your lo-
cal Propane Gas Dealer can give you a "Scratch and Sniff"
pamphlet. Use it to nd out what the propane odor smells like.
If you suspect that your Propane Gas has a weak or abnormal
odor, call your Propane Gas Dealer.
• If you are not qualied, do not light pilot lights, perform
service, or make adjustments to appliances on the Propane
Gas system. If you are qualied, consciously think about the
odor of Propane Gas prior to and while lighting pilot lights or
performing service or making adjustments.
• Sometimes a basement or a closed-up house has a musty
smell that can cover up the Propane Gas odor. Do not try to
light pilot lights, perform service, or make adjustments in an
area where the conditions are such that you may not detect
the odor if there has been a leak of Propane Gas.
• Odor fade, due to oxidation by rust or adsorption on walls
of new cylinders and tanks, is possible. Therefore, people
should be particularly alert and careful when new tanks or
cylinders are placed in service. Odor fade can occur in new
tanks, or reinstalled old tanks, if they are lled and allowed to
set too long before relling. Cylinders and tanks which have
been out of service for a time may develop internal rust which
will cause odor fade. If such conditions are suspected to ex-
ist, a periodic sniff test of the gas is advisable. If you have
any question about the gas odor, call your Propane Gas
Dealer. A periodic sniff test of the Propane Gas is a good
safety measure under any condition.
• If, at any time, you do not smell the Propane Gas odorant and
you think you should, assume you have a leak. Then take the
same immediate action recommended above for the occasion
when you do detect the odorized Propane Gas.
• If you experience a complete "gas out," (the container is un-
der no vapor pressure), turn the tank valve off immediately. If
the container valve is left on, the container may draw in some
air through openings such as pilot light orices. If this oc-
curs, some new internal rusting could occur. If the valve is left
open, then treat the container as a new tank. Always be sure
your container is under vapor pressure by turning it off at the
container before it goes completely empty or having it relled
before it is completely empty.

Each appliance should have its own manual gas shut-off valve.
A manual main gas shut-off valve should be located in the vicinity
of the unit. Where none exists, or where its size or location is not
adequate, contact your local authorized installer for installation
or relocation.
Compounds used on threaded joints of gas piping shall be resistant
to the action of liqueed petroleum gases. The gas lines must be
checked for leaks by the installer. This should be done with a soap
solution watching for bubbles on all exposed connections, and if
unexposed, a pressure test should be made.
Never use an exposed ame to check for leaks. Appliance must
be disconnected from piping at inlet of control valve and pipe
capped or plugged for pressure test. Never pressure test with
appliance connected; control valve will sustain damage!
NOTE: The gas control is equipped with a captured screw type
pressure test point, therefore it is not necessary to provide a 1/8"
test point up stream of the control.
A gas valve and ground joint union should be installed in the gas
line upstream of the gas control to aid in servicing. It is required by
the National Fuel Gas Code that a drip line be installed near the gas
inlet. This should consist of a vertical length of pipe tee connected
into the gas line that is capped on the bottom in which condensation
and foreign particles may collect.
When using copper or ex connector use only approved ttings.
Always provide a union so that gas line can be easily disconnected
for burner servicing.
The appliance and it's individual shut off valve must be disconnected
from supply piping system during any pressure testing of that system
at test pressures in excess of 1/2 psig (3.5 kPa).
The appliance must be isolated from the gas supply piping system
by closing its individual manual shut off valve during any pressure
testing of the gas supply piping system at test pressures equal to
or less than 1/2 psig (3.5 kPa).
CAUTION
If one of the procedures results in pressures in excess of
1/2 psig (14" w.c.) (3.5 kPa) on the stove gas valve, it will
result in a hazardous condition.
Checking Manifold Pressure
Both Propane and Natural Gas valves have a built-in pressure
regulator in the gas valve. Natural Gas models will have a manifold
pressure of approximately 3.5" w.c. (.871 kPa) for maximum input or
1.7" w.c. (.423 kPa) for minimum input at the valve outlet with the inlet
pressure to the valve from a minimum of 5.0" w.c. (1.245 kPa) for the
purpose of input adjustment to a maximum of 10.5" w.c. (2.615 kPa).
Propane Gas models will have a manifold pressure approximately
10.0" w.c. (2.49 kPa) for maximum input or 5.9" w.c. (1.469 kPa)
for minimum input at the valve outlet with the inlet pressure to the
valve from a minimum of 11.0" w.c. (2.739 kPa) for the purpose of
input adjustment to a maximum of 13.0" w.c. (3.237 kPa).
A 1/8" (3 mm) N.P.T. plugged tapping, accessible for test gauge
connection, is located on the outlet side of the gas control.

42603-4-0421 Page 9
In selecting a location for installation, it is necessary to provide ad-
equate accessibility clearances for servicing and proper operation.

Sidewall Venting
The maximum vertical and horizontal distances are 25 feet and 12
feet, respectively. Vertical dimensions are based on top of stove to
centerline of pipe. Horizontal dimensions are based on centerline
of pipe to termination.
Under no circumstances should combustible materials (including
siding) be closer than 3" from the top of the 6 5/8" pipe or closer
than 1" on the sides and bottom.
Cutting the Hole
After the appliance has been positioned in its permanent location,
the hole through the exterior wall of the house can be cut. This
hole needs to be 10" high x 9" wide for 4 x 6 pipe and 12-1/2 high
x 10-1/2 wide for 5 x 8 pipe with its center line determined by the
amount of vertical arise and horizontal run of the termination. When
locating the hole it must be noted that the bottom of the cap must
be 12" above the ground level, and top of the cap must be no less
than 18" below a combustible projection, and no closer than 9" to
any wall running parallel to vent termination.

To Use the Vent Graph
EXAMPLE A:
If the vertical rise from the appliance outlet is 21 feet, the horizontal
run to the outer wall ange of the vent termination must not exceed
4 feet with one 90° elbow.
EXAMPLE B:
If the vertical rise from the appliance outlet is 14 feet, the horizontal
run to the outer wall ange of the vent termination must not exceed
11 feet with one 90° elbow.
VENTING STOVE (CONT'D)
SPECIAL NOTE: For each 45 degree elbow installed in the horizontal
run, the length of the horizontal run MUST be reduced by 18 inches
(457.2 mm). This does not apply if the 45 degree elbows are installed
on the vertical rise of the vent system.
Example: According to the chart the maximum horizontal run is 12
feet and if two 45 degree elbows are required in the horizontal run
it must be reduced to 9 feet.
The maximum number of 45 degree elbows permitted per side
wall installation is two. These elbows can be installed in either the
vertical rise or horizontal run.

Vertical Sidewall Installations
Important! Minimum clearance between vent pipes and combustible
materials is one inch (25 mm) on, bottom and sides and three inches
(51 mm) on top.
Important! When vent termination exits through foundation less
than 20" below siding outcrop, the vent pipe must ush up with the
siding. 46-DVA-HC termination cap must also be used.
Information on Various Venting Routes and Components
Important: It is always best to locate the appliance in such a way
that minimizes the number of offsets and horizontal vent length.
Since it is very important that the venting system maintain its balance
between the combustion air intake and the ue gas exhaust, certain
limitations as to vent congurations apply and must be strictly
adhered to.
The graph showing the relationship between vertical and horizontal
side wall venting will help to determine the various vent lengths
allowable.
The horizontal vent run refers to the total length of vent pipe from
the vent elbow of the appliance to the face of the outer wall.

Installing Vent Components
Begin the vent system installation by installing the rst Simpson
Duravent component on the top of the appliance with a 45° elbow
and rotate the vent elbow to the desired position then add horizontal
and vertical pipe lengths and then a horizontal or vertical termination
kit. Elbows can be added where necessary. See Pages 11 through
15 for venting requirements.
Simpson Duravent vent system components lock into place by
sliding the concentric pipe section with four equally spaced interior
beads onto the appliance collar or previously installed component
end with four equally spaced indented sections. When the internal
beads of each starting 6 5/8 inch outer pipe line up, rotate pipe
section clockwise 90° (approximately 3 inches). The vent pipe is
now locked together.
Continue adding components per the pre-planned vent system
conguration. Be certain that each succeeding vent component
is securely tted and locked into the preceding component in the
vent system.

Installing Firestops
Firestops are required for safety whenever the vent system passes
through an interior wall, an exterior wall, or a ceiling. These restops
act as a rebreak heat shield and as a means to insure that minimum
clearances are maintained to the vent system.
Horizontal runs in the vent system which pass through either interior
or exterior walls, require the use of wall restops on both sides of
the wall through which the vent passes.
Position the restops on both sides of the 9-1/8 inch x 11 inch hole
for 4 x 6 inch pipe and 10-1/2 x 10-1/2 inch hole for 5 x 8 inch pipe,
previously cut. Secure with nails or screws. Continue the vent run
through the restops. See Figure 15.

Vertical runs of this system which pass through ceilings require the
use of one ceiling restop at the hole in each ceiling through which
the vent passes.
Position a plumb bob directly over the center of the vertical vent
component and mark the ceiling to establish the center point of the
vent. Drill a hole or drive a nail through this center point and check
the oor above for any obstructions such as wiring or plumbing
runs. Reposition the appliance and vent system, if necessary, to
accommodate ceiling joists and/or obstructions.
Cut a 9 inch x 9 inch hole through the ceiling, using the center point
previously marked. Frame the hole with framing lumber the same
size as the ceiling joists. See Figure 16. If the area above the ceiling
is NOT an attic, position and secure the ceiling restop (46DVA-FS)
on the ceiling side of the previously cut and framed hole. See Figure
17. If the area above the ceiling IS an attic, position and secure
the restop on top of the previously framed hole. See Figure 18.
NOTE: Remove insulation from the framed area in the attic before
installing the restop and/or vent stop and/or vent pipes.

NOTE: Termination cap should pass through the wall restop from
the exterior of the building. Adjust the termination cap to
its nal exterior position on the building.
WARNING
Termination cap must be positioned so that the arrow is
pointing up.
Using the termination cap in the center of the square hole, attach
the termination cap with the four wood screws provided. Before
attachment of the termination, run a bead of silicone sealant rated
above 250°F on its outside edge too, so as to make a seal to that
exterior wall.
NOTE: Wood screws can and should be replaced with appropriate
fasteners for use on stucco, brick, concrete or other types
of siding.
CAUTION
If exterior walls are nished with siding (vinyl, aluminum, etc.),
it is necessary to install the vinyl siding shield (46DVA-VSS).
Vinyl siding shield (46DVA-VSS) will be installed between the vent

vent termination bolts onto the at portion of the vinyl siding standoff,
so an air space will exist between the wall and the termination cap. Figure 19

Vertical Terminations
Locate and mark the center point of the venting pipe. Using a nail
on the underside of the roof and drive this nail through this center
point. Make the outline of the roof hole around this center point.
NOTE: Size of the roof hole dimensions depend on the pitch of the
roof. There must be a 1 inch clearance (25 mm) to the vertical pipe
sections. This clearance is to all combustible material.
Cover the opening of the vent pipe and cut and frame the roof hole.
Use framing lumber the same size as the roof rafters and install the
frame securely. Flashing anchored to frame must withstand high
winds. The storm collar is placed over this joint to make a watertight
seal. Non-hardening sealant should be used to completely seal this
ashing installation.
Determining Minimum Vent Height Above the Roof.
WARNING
Major U.S. building codes specify minimum chimney and/or
vent height above the roof top. These minimum heights are
necessary in the interest of safety. These specications are
summarized in Figure 20.
ROOF PITCH H (MINIMUM
FEET METER
FLAT TO 6/12 1.0 0.30
6/12 TO 7/12 1.25 0.36
OVER 7/12 TO 8/12 1.5 0.46
OVER 8/12 TO 9/12 2.0 0.61
OVER 9/12 TO 10/12 2.5 0.76
OVER 10/12 TO 11/12 3.25 0.99
OVER 11/12 TO 12/12 4.0 1.22
OVER 12/12 TO 14/12 5.0 1.52
OVER 14/12 TO 16/12 6.0 1.83
OVER 16/12 TO 18/12 7.0 2.13
OVER 18/12 TO 20/12 7.5 2.27
OVER 20/12 TO 21/12 8.0 2.44

Note that for steep roof pitches, the vent height must be increased.
In high wind conditions, nearby trees, adjoining roof lines, steep
pitched roofs, and other similar factors can result in poor draft, or
down-drafting. In these cases, increasing the vent height may solve
this problem.
When terminating the vent cap near an exterior wall or overhang,
maintain minimum clearances as shown in Figure 20.
General Maintenance
Conduct an inspection of the venting system semi-annually.
Recommended areas to inspect are as follows:
1. Check areas of the venting system which are exposed to
the elements for corrosion. These will appear as rust spots
or streaks and, in extreme cases, holes. These components
should immediately be replaced.
2. Remove the cap and shine a ashlight down the vent. Remove
any bird nests or other foreign material.
3. Check for evidence of excessive condensate, such as water
droplets forming in the inner liner and subsequently dripping
out at joints. Continue condensate can cause corrosion of caps,
pipe and ttings. It may be caused by having excessive lateral
runs, too many elbows and exterior portions of the system being
exposed to cold weather.
4. Inspect joints to verify that no pipe sections or ttings have been
disturbed and, consequently, loosened.Also, check mechanical
supports, such as wall straps or plumbers' tape for rigidity.
Venting terminal shall not be recessed into a wall or siding. A
removable panel or other means must be provided in the enclosure
for visual inspection of the ue connection.
Installing the Vent System in a Chase
A chase is a vertical box like structure built to enclose the gas
appliance and/or it's vent system. Vertical vent runs on the outside of
a building may be, but are not required to be installed inside a chase.
Figure 22
CAUTION
Treatment of restop spacers and construction of the chase
may vary with the type of building. These instructions are
not substitutes for the requirements of local building codes.
Therefore, your local building codes must be checked to
determine the requirements for these steps.
VERTICAL TERMINATION

42603-4-0421Page 20
Ahorizontal pipe support MUST BE used for each 3 feet of horizontal
run. The pipe supports should be placed around 6-5/8 inch diameter
pipe and nailed in place to framing members. There MUST BE a 2
inch clearance to combustibles above 6-5/8 inch diameter pipe and
elbows and 1 inch clearance on both sides and bottom of 6-5/8 inch
to combustibles on all horizontal pipe sections and elbows.
Vertical runs of this vent systems must be supported every 4 feet
above the appliance ue outlet by wall brackets attached to the
6-5/8 inch vent pipe and secured with nails or screws to structural
framing members.
NOTE: When installing this vent system in a chase, it is always good
building practice to insulate the chase as you would the outside walls
of your home. This is especially important for cold climate installations.
Upon completion of building your chase framing, install the vent
system by following the instructions in this manual. Remember to build
the chase large enough so that minimum clearance of combustible
materials (including insulation) to the vent system are maintained.
Vertical Through the Roof Applications
Your Gas Stove has been approved for
a) Vertical installations up to 40 feet of vent run
b) Two sets of 45 degree elbow offsets within these vertical
installations. From 0 to a maximum of 8 feet a vent pipe can be
used between elbows.
c) Wall straps must be used to support offset pipe every 4 feet.
This applications will require that you rst determine the roof pitch
and use the appropriate venting components.
Reassembly and Resealing Vent-Air Intake System
Attach vent pipe to appliance air drop with four 1/2" hex-head screws
in position, replace vertical and horizontal pipe lengths, elbows and
horizontal or vertical termination kit.
All vent system components lock into place by sliding the concentric
pipe section with four equally spaced interior beads onto the
appliance collar or previously installed component end with four
equally spaced indented sections. When the internal beads of each
starting 6 5/8 inch outer pipe line up, rotate pipe section clockwise
90° (approximately 3 inches). The vent pipe is now locked together.
Continue replacing components per the vent system conguration.
Be certain that each succeeding vent component is securely tted
and locked into the preceding component in the vent system.
