1. Locate the unit in the framing, rough in the gas
(preferably on the right side of the unit). Locate
the centerline of the termination and mark wall
accordingly. Cut an square hole in the wall - see
chart (inside dimension).
Note: If installing termination on a siding
covered wall, a vinyl siding stando
or vinyl furring strips must be used
to ensure that the termination is not
recessed into the siding.
2. Level the replace and fasten it to the framing
using nails or screws through the nailing strips.
3. Assemble the vent assembly by applying Mill-Pac
to the inner ue collar of the termination and
slipping the inner ex liner over it at least 1-3/8"
(35mm). Fasten with the 3 screws (drilling pilot
holes will make this easier). Apply Mill-Pac to
the outer ex pipe and slip it over the outer ue
collar of the vent terminal at least 1-3/8"(35mm)
and fasten with the 3 screws.

NOTE: Horizontal sections must be
supported at intervals not exceeding
3 feet (0.9 meter). (Flame picture
and performance will be aected by
sags in the liner).
4. Separate the 2 halves of the wall thimble and
securely fasten the one with the tabs to the
outside wall making sure that the tabs are
on top and bottom. Fasten the other thimble
half to the inside wall. The thimble halves slip
inside each other and can be adjusted for 2
x 4 or 2 x 6 walls.
5. Slip the assembled liner and termination
assembly through the thimble making sure the
termination cap faces up (there are markings
on the cap that show which way is up). This
will position the termination cap with proper
down slope for draining water. Fasten the cap
to the outer wall with the 4 supplied screws.
6. Pull the centre inner and outer ex liner out
enough to slip over the ue collars of the
replace. (You may wish to cut the liner
shorter to make it more workable.) Do not
bend liner more than 90º. The liners must
slip over the collars a minimum of 1-3/8".
7. Apply Mill-Pac over the replace inner ue
collar and slip the inner ex liner down over
it and attach with 3 supplied screws.
8. Do the same with the outer ue collar and
outer ex liner.
9. Apply a bead of silicone between the thimble
and termination and around the outer edge
of the terminal at the wall in order to keep
the water out.
IMPORTANT: Do not locate termination
hood where excessive snow or ice
buildup may occur. Be sure to check
vent termination 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.
* Clearances noted below must be maintained;
except when passing through a wall, ceiling or
at the termination where the use of a restop or
wall thimble reduces clearance to 1-1/2" (38mm).

Horizontal Terminations - Flex Vent 5" x 8" (Non Power Vent)

16 | City Series CB50E Direct Vent Gas Fireplace
Venting Introduction (Non Power Vent)
The CB50E uses the "balanced ue" technology co-axial system. The inner liner vents products of combustion to the outside while the outer liner draws
outside combustion air into the combustion chamber, thereby eliminating the need to use heated room air for combustion and losing warm room air up
the chimney.
The gas appliance and vent system must be vented directly to the outside of the building, and never be attached to a chimney serving a separate solid fuel
or gas burning appliance. Each direct vent gas appliance must use it's own separate vent system. Common vent systems are prohibited.
Venting Arrangement for Horizontal Terminations (Rigid and Flex)
The diagram shows all allowable combinations of vertical runs with horizontal terminations, using one 90oelbow (two 45o elbows equal one 90oelbow).
• Maintain clearances to combustibles as listed in "Clearances" section
• Horizontal vent must be supported every 3 feet.
• Firestops are required at each oor level and whenever passing through a wall.
• A vent guard should be used whenever the termination is lower than the specied minimum or as per local codes.
VENT RESTRICTOR SETTING:
Vent restrictor factory set at Set 0.
Refer to the "Vent Restrictor Position" section for details on how to change the vent restrictor from the factory setting of Set 0 to Set 3 if required.

Horizontal Terminations - Rigid Pipe 5" x 8" (Non Power Vent)
The minimum components required for a basic horizontal
termination are:
1 Horizontal Termination Cap
1 Rigid Pipe Adaptor (770-994)
1 Wall Thimble
1 Length of pipe to suit wall thickness
(see chart)
Wall thickness is measured from the back standos to the inside
mounting surface of termination cap. For siding other than vinyl
furring strips may be used, instead of the vinyl siding stando, to
create a level surface to mount the vent terminal. The Terminal
must not be recessed into siding. Measure the wall thickness
including furring strips.
If a Vinyl Siding Stando is required (it must be used with vinyl
siding), measure to outside surface of wall without siding and
add 2 inches.
When using Rigid Vent other than
Simpson Dura-Vent, 3 screws must be
used to secure rigid pipe to adaptor.
This product has been evaluated by Intertek
for using a Rigid Pipe Adaptor in conjunction
with Duravent Direct-Vent, Selkirk Direct-Temp,
Ameri Vent Direct Venting, ICC Excel Direct,
Olympia Ventis DV, and Security Secure Vent
systems. Use of these systems with the Rigid
Pipe adaptor is deemed acceptable and does not
aect the Intertek WHI listing of components.
WARNING:
Do not combine venting components from
dierent venting systems.
However use of the the AstroCapTM and FPI
Riser is acceptable with all systems.
The FPI AstroCapTM and FPI Riser Vent terminal are certied for installations using FPI venting systems as well as Simpson Dura-Vent®Direct Vent, American

7. Ensure that the pipe clearances to combustible
materials are maintained (Diagram 55). Install
the termination cap.
Note: If installing termination on a vinyl siding
covered wall, a vinyl siding stando or
furring strips must be used to ensure
that the termination is not recessed
into the siding.
The four wood screws provided should be
replaced with appropriate fasteners for stucco,
brick, concrete, or other types of sidings.
8. Before connecting the horizontal run of vent
pipe to the vent termination, slide the Wall
Thimble over the vent pipe. The wall thimble
is required for all horizontal terminations.
9. Slide the appliance and vent assembly towards
the wall carefully inserting the vent pipe into
the vent cap assembly. It is important that the
vent pipe extends into the vent cap sucient
distance so as to result in a minimum pipe
overlap of 1-1/4 inches (32mm). Secure the
connection between the vent pipe and the vent
cap.
10. Install wall thimble in the center of the framed
hole and attach with wood screws.
Install the vent system according to the
manufacturer's instructions included with the
components.
1. Set the unit in its desired location. Check to
determine if wall studs or roof rafters are in
the way when the venting system is attached.
If this is the case, you may want to adjust the
location of the unit. Rough in the gas preferably
on the right side of the unit and the electrical
(junction block is on the left side) on the left.
2. Direct Vent pipe and ttings are designed with
special twist-lock connections to connect the
venting system to the appliance ue outlet. A
twist-lock appliance adaptor is required.
3. In conjunction with the Approved Vent system,
install the adaptor after the unit is set in its
desired location. Slip the adapter over the
existing inner and outer ue collar. Fasten to
the outer collar only with the 3 supplied screws
(drilling pilot holes will make this easier).
every 3 feet (0.9meter). Wall straps are
available for this purpose.
6. Mark the wall for a square hole.-see chart to left
for size. The center of the square hole should
line up with the center-line of the horizontal
pipe. Cut and frame the square hole in the
exterior wall where the vent will be terminated.
See diagram 54 for center line requirements.
If the wall being penetrated is constructed of
non-combustible material, i.e. masonry block
or concrete, an 8" (203mm) diameter hole is
acceptable.
Notes:
a) The horizontal run of vent must be level,
or have a 1/4 inch rise for every 1 foot of
run towards the termination. Never allow
the vent to run downward. This could cause
high temperatures and may present the
possibility of a re.
b) The location of the horizontal vent
termination on an exterior wall must meet
all local and national building codes, and
must not be blocked or obstructed. See
"Exterior Vent Termination Locations"
section for more details.
4. Level the replace and fasten it to the framing
using nails or screws through the top and side
nailing strips.
5. Assemble the desired combination of pipe and
elbows to the appliance adaptor and twist-lock
for a solid connection.
Note:Forbestresultsandoptimumperformance
with each approved venting system, it
is highly recommended to apply “Mill-
Pac” sealant (supplied) to every inner
pipe connection. Failure to do so may
result in drafting or performance issues
not covered under warranty.

c) Snorkel Terminations:
For installations requiring a vertical rise on the
exterior of the building, 14-inch and 36-inch
tall Snorkel Terminations are available, as well
as the standard Riser Vent. Follow the same
installation procedures as used for standard
Horizontal Termination. NEVER install the snorkel
upside down.
Below Grade Snorkel Installation
If the snorkel termination must be installed below
grade, i.e. basement application, proper drainage
must be provided to prevent water from entering
the snorkel termination. See diagram 56. Do not
attempt to enclose the snorkel within the wall
or any other type of enclosure.

Vertical Terminations - Rigid Pipe 5" x 8" (Non Power Vent)
The minimum components required for a basic vertical termination are:
1 Vertical Termination Cap
1 Rigid Pipe Adaptor (770-994)
1 Ceiling Firestop
1 Flashing
1 Storm Collar
1 Length of pipes to suit wall thickness & vent run
(see chart)
When using Rigid Vent other than
Simpson Dura-Vent, 3 screws must be
used to secure rigid pipe to adaptor.
Galvanized pipe is desirable above the rooine due to its higher corrosion
resistance. Continue to add pipe sections through the ashing until the
height of the vent cap meets the minimum height requirements specied
in table below or local codes. Note that for steep roof pitches, the
vertical height must be increased. A poor draft, or down drafting
can result from high wind conditions near big trees or adjoining
roof lines, in these cases, increasing the vent height may solve the
problem.
