IMPORTANT SAFETY INFORMATION

23340-2-1007Page 4
Some people cannot smell well. Some people cannot smell the
odor of the chemical put into the gas. You must find 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 filter the odorant. Odorants
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.
Propane (LP-Gas) is a flammable gas which can cause fires
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
accident. 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 read-
ing the following information, you feel you still need more
information, please contact your gas supplier.
• Learn to recognize the odor of LP-Gas. Your local LP-Gas
Dealer can give you a “Scratch and Sniff” pamphlet. Use it to
find 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 qualified, do not light pilot lights, perform service,
or make adjustments to appliances on the LP-Gas system. If
you are qualified, 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 filled and allowed to set too
long before refilling. 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 orifices. 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 refilled
before it is completely empty.
• 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 firefighters
declare them to be safe.
• Use your neighbor’s phone and call a trained LP-Gas service
person and the fire 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 firefighters 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.
SOME POINTS TO REMEMBER
NO ODOR DETECTED - ODOR FADE
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!

The gas pipeline can be brought in through the right or left side of
the appliance. Consult the current National Fuel Gas Code, ANSI
Z223.1 CAN/CGA-B149 (.1 or .2) installation code.
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 liquefied 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 flame 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.
On direct ignition valves, hex plugs may be replaced with hose fittings
for pressure checks, then reinstalled before operating fireplace.
When using copper or flex connector use only approved fittings.
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 fireplace 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).

Note: Since some municipalities have additional local codes, it is
always best to consult your local authority and installation code.
The use of the following gas connectors is recommended:
— ANS Z21.24 Appliance Connectors of Corrugated Metal Tubing
and Fittings.
— ANS Z21.45 Assembled Flexible Appliance Connectors of
Other Than All-Metal Construction
The above connectors may be used if acceptable by the authority
having jurisdiction. The state of Massachusetts requires that a flexible

Converting flue take-off to rear venting
When switching out the flue and inlet vent collars to run horizontally
off the rear vent, the following steps must be taken.
1. Remove the inlet vent collar (8 screws) and flue collar (4 screws)
from the top of the fireplace, and set to the side.
2. Remove the inlet cover plate and flue cover plate located on the
back of the fireplace. These will be used to close the top flue
and inlet openings.
3. Insert the insulation retainer bracket and insulation into the top
flue pipe before reinstalling the flue cover plate over the top flue
with 4 screws.
4. Reinstall the inlet cover plate over the top inlet opening with 4
screws. See illustration above..
5. Install the flue collar assembly to the rear flue with 4 screws.
6. Install the inlet vent collar to the rear of the fireplace with 8
screws.
7. This completes the conversion for a rear vent application.
Note: for top vented installations, the insulation and retainer are
to be removed from the flue pipe and discarded.

Note: For finishing to top of fireplace, refer to Figure 12.
Figure 12
Attention: Add 3-3/4" to “A” dimensions when using a flush
mantel base.
Attention: If a base or mantel is not used and the appliance is
installed directly on carpeting, tile or other combustible material
other than wood flooring, it shall be installed on a metal or wood
panel extending the full width and depth of the appliance. The
vertical dimension in Figure 12 must be adjusted when a metal or
wood panel is placed beneath the appliance.
Finishing (Figures 13 and 14)
Finish the walls with the material of your choice. Figure 3 on
page 8 shows the minimum vertical and corresponding maximum
horizontal dimensions of mantels or other combustible projections
above the top front edge of the fireplace.
Only non-combustible materials may be used to cover the black
fireplace front.
Warning: When finishing the fireplace never obstruct
or modify the air inlet/outlet louvers in any manner.
Provide adequate clearances around air openings into the
combustion chamber.
Caution: If the joints between the finished wall and the fireplace
surround (top and sides) are sealed, a 300°F minimum sealant
material must be used. These joints are not required to be sealed.
Only non-combustible material (using 300°F minimum adhesive if
needed), can be applied as facing to the fireplace surround.
Flush Mount Mantel Installation (Figure 11)
The fireplace must extend 3/4" beyond finished wall surface when
using a flush mount mantel. Refer to Figure 11 to locate nailing
flanges on fireplace sides. Mark and drill two (2) 1/8" holes into
fireplace side to mount each nailing flange. Use eight (8) 1/2" hex-
head screws supplied in hardware package to attach nailing flanges
to fireplace sides.
Figure 11
Attention: When fireplace is installed in optional full cabinet mantel
or corner mantel the (4) four nailing flanges shown in Figure 11 will
not be installed on the side of outer casing. The fireplace will be
attached to the full cabinet mantel or corner mantel with the (2) two
nailing flanges located on the top of the outer casing assembly.
Framing (Figure 12)
Fireplace framing can be built before or after the fireplace is set in
place. Framing should be positioned to accommodate wall covering
and fireplace facing material. The fireplace framing should be
constructed of 2 x 4 lumber or heavier. The framing headers may
rest on the fireplace standoffs. Refer to Figure 12 for minimum
framing dimensions.
CAUTION: MEASURE FIREPLACE DIMENSIONS AND
VERIFY FRAMING METHODS, AND WALL COVERING
DETAILS BEFORE FRAMING CONSTRUCTION

To Use the Vent Graph (Figure 20)
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 floor of the unit is 35
feet, the horizontal run to the outer wall flange must not
exceed 6.5 feet.
EXAMPLE B:
If the vertical dimension from the floor of the unit is 6.5
feet, the horizontal run to the outer wall flange 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 first elbow does not get
counted.
Note: LP and Nat gas models can be top vented.

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" (178mm) below grade level.
The 7" (178mm) 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 final position.
Cutting the Hole (Figures 24)
After the fireplace has been positioned in its permanent location, the hole
through the exterior wall of the house can be cut. This hole must be 10"
(254mm) high x 10" (254mm) wide with its center line determined by the
amount of vertical rise and horizontal run of the termination. See Figure
24. When locating the hole it must be noted that the bottom of the cap
must be 12" (305mm) above the ground level, and top of the cap must
be no less than 18" (457mm) below a combustible projection, and no
closer than 9" (229mm) to any wall running parallel to vent termination.

place and survey how best to vent the unit. After the vent configuration has been decided, stretch the flex pipe components out, then trim
off what will not be needed.
Refer to the fireplace installation manual for information on vertical venting requirements. The maximum length of vent when using flex
venting is 35 feet total. Contact your dealer or distributor for information on flex vent extension kits that may be added to the DVVK-
4FV kit, in order to terminate up to 35 feet. Available extension kits include the DVEK-10 (10’ Flex) or the DVEK-25 (25’ Flex) exten-
sion kits. The extension kits include connection hardware.
Installation of the Vertical Flex Termination Kit
WARNING
Ensure that the venting system exits the structure through the roof and does not terminate less than 12 inches (305mm) above the
roof.
WARNING
Refer to your fireplace homeowner’s manual for the minimum and maximum venting requirement of your fireplace prior to installa-
tion. Failure to do so may cause a fire hazard.
WARNING
This flexible pipe termination kit is ONLY for vertical terminations.
WARNING
Any horizontal run section must have a 1/4” rise for every one (1) foot of run towards the vent termination. Never allow the vent pipe
to run downward. This could cause high temperatures and may present a fire hazard. This vertical kit may incorporate two (2) 90 de-
gree bends, but must terminate vertically.
CAUTION
This flex vent kit can be installed either vertically or horizontally off of Direct Vent Series fireplaces but must only terminate verti-
cally.
WARNING
Because of sharp edges, always use gloves when handling the flex vent components.
CAUTION
Vent connections should overlap a minimum of 1” for proper sealing.
CAUTION
Always stretch and secure venting with metal strapping secured with nails (nails and strapping not supplied) to ensure that the flex
vent runs remain true.
INSTALLATION NOTE:
If space permits, it is generally easier to attach venting in the top vent configuration.

23340-2-1007Page 20
1. Unpack vent components and check all items for shipping
damage.
2. For this venting system to operate as designed it is depen-
dent on the use of all parts and procedures detailed in these
instructions. Failure to follow these instructions may poten-
tially affect the performance of this vent system and the at-
tached appliance.
3. As per the fireplace manufacturer’s instructions, replace the
existing 6 5/8” diameter fireplace vent adapter with the 7”
diameter flex vent fireplace adapter included in the vent kit.
Install the adapter collar with the screws removed from the
standard fireplace collar. Refer to the fireplace manual for ad-
ditional information on the vent collar removal and installa-
tion.
4. Once the fireplace location has been determined, mark the
ceiling where the flex vent will pass through. Cut an opening
for installation of the firestop thimble assembly. The open-
ing must measure a minimum of 9-1/2” x 9-1/2” square. See
Figure 27.
5. Next, determine the location for the cutout in the roof open-
ing. This opening must be large enough to provide a mini-
mum 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 firestop. It is also designed with a pivoting
firestop for use with 0 - 3/12 pitch cathedral ceilings.
7. To begin vent system assembly, first layout all the vent com-
ponents on the floor in the order in which they will be as-
sembled.
8. Stretch the 4” diameter inner flex flue and 7” diameter outer
flex vent to the maximum length of 6 feet.
9. Install the spring spacers provided around the 4” diameter
flex flue at 1 foot intervals, then slide the flue pipe with spac-
ers into the 7” diameter outer flex vent pipe. Make sure the
springs are spaced evenly starting at 12 inches from the fire-
place collar. See Figure 28.
