SAFETY INFORMATION FOR USERS OF LP GAS
Propane (LP-Gas) 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 precautions which can protect both you and your family from an
accident. Read them carefully now, then review them point
LP-GAS WARNING ODOR
If a gas leak happens, you should be able to smell the gas because of the odorant put in the LP-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.
• LP-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
reghters declare them to be safe.
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 LP-Gas is colorless, and it can fade under some
circumstances. For example, if there is an underground leak, the
movement of the gas through soil can lter the odorant. Odorants
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 information, please
contact your gas supplier.
• Use your neighbor’s phone and call a trained LP-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 reghters check for escaped
gas. Have them air out the area before you return. Properly
trained LP-Gas service people should repair the leak, then
check and relight the gas appliance for you.
in LP-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.
LP-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 LP-Gas. Your local LP-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 LP-Gas has a weak or abnormal odor, call your
LP-Gas Dealer.
• If you are not qualied, do not light pilot lights, perform
service, or make adjustments to appliances on the LP-Gas
system. If you are qualied, consciously think about the odor
of LP-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 LP-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 LP-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 relling. 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 exist, a
periodic sniff test of the gas is advisable. If you have any
question about the gas odor, call your LP-Gas dealer. A
periodic sniff test of the LP-Gas is a good safety measure
under any condition.
• If, at any time, you do not smell the LP-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 LP-Gas.
• If you experience a complete “gas out,” (the container is under 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 orices. If this
occurs, 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
relled before it is completely empty.

Installing a New Main Gas Cock
Each appliance should have its own manual gas cock.
A manual main gas cock 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 liqueed 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 millivolt gas controls are 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.
When using copper or ex connector use only approved ttings.
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 (3.5kPa).
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 (3.5kPa).
Attention! If one of the procedures results in pressures in excess
of 1/2 psig (14" w.c.) (3.5 kPa) on the replace gas valve, it will
result in a hazardous condition.
Checking Manifold Pressures
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. (.871kPa) at the valve outlet
with the inlet pressure to the valve from a minimum of 4.5" w.c.
(1.120kPa) for the purpose of input adjustment to a maximum of
14.0" w.c. (3.484kPa). Propane gas models will have a manifold
pressure approximately 10.0" w.c. (2.49kPa) at the valve outlet
with the inlet pressure to the valve from a minimum of 10.8" w.c.
(2.68kPa) for the purpose of input adjustment to a maximum of
14.0" w.c. (3.484kPa).

To Use the Vent Graph (Figure 17)
1. Determine the height of the center of the horizontal vent
pipe. Using this dimension on the Sidewall Vent Graph,
locate the point it intersects with the slanted graph
line.
2. From the point of this intersection, draw a vertical line
to the bottom of the graph.
3. Select the indicated dimension, and position the unit in
accordance with same.
EXAMPLE A:
If the vertical dimension from the oor of the unit is 35 feet,
the horizontal run to the outer wall ange must not exceed
6.5 feet.
EXAMPLE B:
If the vertical dimension from the oor of the unit is 6.5
feet, the horizontal run to the outer wall ange must not
exceed 14.5 feet.
Special Note: For each 45 degree elbow installed in the
horizontal run, the length of the horizontal run MUST be
reduced by 18" (45cm). This does not apply if the 45 degree
elbows are installed on the vertical part of the vent system.
Reduce 3' for every 90° elbow.
Example: According to the chart the maximum horizontal
vent length is 20' and if two 45 degree elbows are required
in the horizontal vent it must be reduced to 17'.
The maximum number of 45 degree elbows permitted per
side wall installation is two (2). These elbows can be installed
in either the vertical or horizontal run.
Note: On vertical venting the rst elbow does not get
counted.
Note: Flue heat shield must be installed for venting
applications with less than two feet of vertical pipe off the
top of the replace.

Below Grade Installation
When it is not possible to meet the required vent terminal clearances
of 12" (305mm) above grade level, a snorkel kit is recommended. It
allows installation depth down to 7" (178 mm) below grade level.
The 7" (178 mm) is measured from the center of the horizontal
vent pipe as it penetrates through the wall.
Ensure the sidewall venting clearances are observed. If venting
system is installed below ground, we recommend a window well
with adequate and proper drainage to be installed around the
termination area.

Positioning the Fireplace
Determine the exact position of the appliance so the direct vent
termination will be centered (if possible) between two (2) studs. This
will avoid any extra framing. All vent kit pipes should be assembled
on the unit after the unit is moved into the nal position.
Cutting the Hole (Figure 23)
After the replace has been positioned in its permanent location,
the hole through the exterior wall of the house can be cut. This hole
must be 12" (305 mm) high x 10" (254 mm) wide with its center
line determined by the amount of vertical rise and horizontal run of
the termination. See Figure 23. When locating the hole it must be
noted that the bottom of the cap must be 12" (305 mm) above the
ground level, and top of the cap must be no less than 18" (457 mm)
below a combustible projection, and no closer than 9" (229 mm) to
any wall running parallel to vent termination. See Figure 24.

Step-By-Step Installation For Flex DV Kit
1. Unpack vent components and check all items for shipping
damage.
2. For this venting system to operate as designed it is dependent on the use of all parts and procedures detailed in these
instructions. Failure to follow these instructions may potentially affect the performance of this vent system and the attached appliance.
3. As per the replace manufacturer’s instructions, replace the
existing 6 5/8” diameter replace vent adapter with the 7”
diameter ex vent replace adapter included in the vent kit.
Install the adapter collar with the screws removed from the
standard replace collar. Refer to the replace manual for additional information on the vent collar removal and installation.
4. Once the replace location has been determined, mark the
ceiling where the ex vent will pass through. Cut an opening
for installation of the restop thimble assembly. The opening must measure a minimum of 9-1/2” x 9-1/2” square. See
Figure 29.
5. Next, determine the location for the cutout in the roof opening. This opening must be large enough to provide a minimum 1” air space clearance from the vertical vent pipe to any
combustible framing.
6. Install the Firestop/Thimble assembly to the framed opening
in the ceiling using common nails or screws.
Note: The thimble assembly is adjustable up or down as
needed within the restop. It is also designed with a pivoting
restop for use with 0 - 3/12 pitch cathedral ceilings.
7. To begin vent system assembly, rst layout all the vent components on the oor in the order in which they will be as-
sembled.
8. Stretch the 4” diameter inner ex ue and 7” diameter outer
ex vent to the maximum length of 6 feet.
9. Install the spring spacers provided around the 4” diameter
ex ue at 1 foot intervals, then slide the ue pipe with spacers into the 7” diameter outer ex vent pipe. Make sure the
springs are spaced evenly starting at 12 inches from the re-
place collar. See Figure 30.

10. With the ex vent assembly and the 48” long hard pipe components laid out on the oor, begin securing these parts to-
gether. First, apply a generous bead of silicone sealant to the
inside of the 4” diameter ex ue (not the end with the preinstalled connector), then slide the ex ue over the 4” diameter hard pipe ue. Be sure to overlap at least 1-1/4”. Secure
this connection with a 4” diameter band clamp provided. Be
careful not to damage or tear the ex ue when tightening
clamp.
11. Repeat the connection process for the outer 7” diameter ex
vent to hard pipe connection. Use silicone sealant at this joint
also, overlap at least 1-1/4”, then secure the joint with the 7”
diameter band clamp provided. Be careful not to damage or
tear the ex vent pipe when tightening the clamp.
12. While the venting is still on the oor, assemble the roof jack
components as shown in Figure 31 and pre-install the roof
jack assembly to the hard pipe approximately 18” from the
top end of the hard pipe.
13. Now the pre-assembled vent system may be carried to the
roof, then lowered through the roof cutout opening (see step
5). Feed the ex vent end down through the roof opening and
restop/thimble assembly installed in steps 4 through 6.
14. Secure the roof support assembly to the roof sheathing with
at least (4) nails/screws through each support bracket. Check
that the combustible clearances through the roof framing will
maintain at least a 1” clearance from the vent pipe.
15. Determine how high the vent terminal should be located
above the roof line based on the roof pitch information shown
in Figure 33. Adjust the vent system height by loosening the
pre-installed roof support pipe clamp and sliding the vent
pipe up or down as pre-determined, then re-tighten the pipe
clamp. Install a couple of sheet metal screws through the pipe
clamp into the outer hard vent pipe to lock in place.
16. Check to make sure that the bottom end of the ex vent is
long enough to reach the replace adapter collars. If too long,
trim off the extra ex vent not needed.
