qualied service person. Some people are more affected
by carbon monoxide than others. These include pregnant
women, people with heart or lung disease or anemia,
those under the inuence of alcohol, and those at high
altitudes.
Propane/LP gas and natural gas are both odorless. An
odor-making agent is added to each of these gases. The
odor helps you detect a gas leak. However, the odor added
to these gases can fade. Gas may be present even though
no odor exists.

Consult local building codes before beginning the
installation. The installer must make sure to select the
proper vent system for installation. Before installing vent
kit, the installer must read this replace manual and vent
kit instructions.
Only a qualied installer/service person should install vent-
ing system. The installer must follow these safety rules:
• Wear gloves and safety glasses for protection.
• Use extreme caution when using ladders or when on
rooftops.
• Be aware of electrical wiring locations in walls and
ceilings.
The following actions will void the warranty on your vent-
ing system:
• Installation of any damaged venting component.
• Unauthorized modication of the venting system.
• Installation of any component part not manufactured
or approved by Vermont Castings Group.
• Installation other than permitted by these instruc-
tions.
Your replace is approved to be vented either through the
side wall, or vertical through the roof.
•
• Flexible UL1777 listed venting may be used in any vent-
ing application where rigid direct vent components can
be used. All restrictions, clearances and allowances that
pertain to the rigid piping apply to the exible venting.
Flex kits may not be modied. Flex kits may be added to
the end of a vent run made of rigid vent sections using
pipe manufacturer's approved ex to pipe adapters. This
may occur only if doing so does not violate any of the
venting length, height, routing, horizontal to vertical ratio
requirements or clearance considerations detailed in this
manual.
• Venting terminals shall not be recessed into a wall or sid-
ing.
• Select the amount of vertical rise desired. All horizontal
run of venting must have 1/4" rise for every 12" (305 mm)
of run towards the termination below 71/2 feet of vertical
rise. With 71/2 feet (2.3 m) or more vertical rise off top of
replace, the horizontal run may run level. NEVER run
vent piping downward.
• Horizontal venting which incorporates the twist lock pipe
must be installed on a level plane without an inclining or
declining slope.
• Horizontal venting which incorporates the use of ex
venting shall have an inclining slope from the unit of 1”
(25 mm) per 24” (610 mm).
There must not be any obstruction such as bushes, gar-
den sheds, fences, decks or utility buildings within 24”
(610 mm) from the front of the termination hood.
Do not locate termination hood where excessive snow or
ice build up may occur. Be sure to check vent termina-
tion area after snow falls, and clear to prevent accidental
blockage of venting system. When using snow blowers,
make sure snow is not directed towards vent termination
area.
It is imperative the vent termination be located observing
the minimum clearances as shown on following page.

When using twist lock pipe it is not necessary to use seal-
ant on the joints.
To join twist lock pipes together, simply align the beads of
the male end with the grooves of the female end, twisting
the pipe until the ange on the female end contacts exter-
nal ange on the male end. It is recommended that you
secure the joints with three (3) sheet metal screws, how-
ever, this is not mandatory with twist lock pipe. Figure 17
To make it easier to assembly the joints, we suggest put-
ting a lubricant (Vaseline or similar) on the male end of the
twist lock pipe prior to assembly.

The Vent Graph should be read in conjunction with the
following vent installation instructions to determine the re-
lationship between the vertical and horizontal dimensions
of the vent system.
1. Determine the height of the center of the horizontal
vent pipe exiting through the outer wall. Using this di-
mension on the Sidewall Vent Graph, Figure 20, locate
the point intersecting 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 re-
place in accordance with same.
If the vertical dimension from the oor of the unit is 11’ (3.4
m) the horizontal run to the face of the outer wall must not
exceed 14’ (4.3 m).
If the vertical dimension from the oor of the unit is 7’ (2.1
m), the horizontal run to the face of the outer wall must not
exceed 8’ (2.4 m).

When installed as a rear vent unit this appliance may be
vented directly to a termination located on the rear wall
behind the appliance.
• Only Vermont Castings Group approved venting com-
ponents are approved to be used in these applications
(Refer to ‘Venting Components’ listed for different in-
stallation requirements).
• The maximum horizontal distance between the rear of
the appliance (or end of the transition elbow in a cor-
ner application) and the outside face of the rear wall is
20” (508 mm). Figure 22
• Only one 45° elbow is allowed in these installations.
• Minimum clearances between vent pipe and combus-
tible materials are as follows:
Top - 3” (76 mm)
- except at outside wall 1" (25 mm)
Sides - 1” (25 mm)
Bottom - 1” (25 mm)

Locate and cut the vent opening in the wall.
For combustible walls rst frame in opening. Figure 26
When using ex vent, the opening will have to be
measured according to the 1” (25 mm) rise in 24” (610
mm) vertical run.
Cut a 9B\,”H x 9B\,” W (244 x 244
mm) hole through the exterior wall and frame as shown.
Figure 23
Hole opening should be 7Z\x”
(191 mm) diameter.
Secure restop to the inside frame, center in the 9B\," x
9B\," vent opening.
Measure the horizontal length requirement for the venting
including a 2” (51 mm) overlap, i.e. from the elbow to the
outside wall face plus 2” (51 mm). Figure 22
Install the 4” (102 mm) vent to the appliance collar and
secure with 3 sheet metal screws. Install the 7” (178 mm)
vent pipe to the appliance collar and secure with 3 sheet
metal screws. It is not necessary to seal this connection.
If a 45° elbow is being used attach the elbow to the appli-
ance in the same manner then attach the venting to the
elbow.
Guide the venting through the vent hole as you place the
appliance in its installed position. Guide the 4” (102 mm)
and 7” (178 mm) collar of the vent termination into the
outer ends of the venting. Do not force the termination. If
the vent pipes do not align with the termination, remove
and realign the venting at the appliance ue collars. Fig-
ure 24. Attach the termination to the wall as outlined in the
instruction sheet supplied with the termination.

Install the 4” (102 mm) ex vent pipe to the appliance col-
lars described in “General Information Assembling Vent
Pipes”, Page 14. If the installation requires a 45° angle,
grasp the vent pipe close to the appliance collar and bend
to 45°. DO NOT exceed 45°. Figure 25
Install the 7” vent pipe in the same manner as Step 2.
There must be a 1/2” (13 mm) rise in a 12” (305
mm) length of ex vent.
Assemble the ex vent to the collars on the termination as
you did on the appliance.

The Vent Graph, showing the relationship between verti-
cal and horizontal side wall venting, will help to determine
the various dimensions allowable.
When vent termination exits through foundations less
than 20” (508 mm) below siding outcrop, the vent pipe
must ush up with the siding.
It is best to locate the replace in such a way that mini-
mizes the number of offsets and horizontal vent length.
The horizontal vent run refers to the total length of vent
pipe from the ue collar of the replace (or the top of the
Transition Elbow) to the face of the outer wall.
Horizontal plane means no vertical rise exists on this por-
tion of the vent assembly.
• The maximum number of 90° elbows per side wall in-
stallation is three (3). Figure 27
• If a 90° elbow is tted directly on top of the replace
ange the maximum horizontal vent run before the ter-
mination or a vertical rise is 36” (914 mm). Figure 28
• If a 90° elbow is used in the horizontal vent run (level
height maintained) the horizontal vent length is re-
duced by 36” (914 mm). Figures 29 & 30. This does
not apply if the 90° elbows are used to increase or
redirect a vertical rise. Figure 27
36CFDV Series Gas Fireplace
20 20305832
According to the vent graph (Page 16) the
maximum horizontal vent length in a system with a 7Z\x’
(2.3 m) rise is 20’ (6 m) and if a 90° elbow is required in
the horizontal vent it must be reduced to 17’ (5.2 m).
In Figures 23 & 24, dimension A plus B must not be great-
er than 17’ (5.2 m)
• The maximum number of 45° elbows permitted per in-
stallation is six (6). These elbows can be installed in
either the vertical or horizontal run.
• For each 45° elbow installed in the horizontal run, the
length of the horizontal run MUST be reduced by 18”
(457 mm). This does not apply if the 45° elbows are
installed on the vertical part of the vent system.
• The maximum number of elbow degrees in a system is
270°. Figure 31

Elbow 2 = 45°
Elbow 3 = 45°
