LOCATION
In selecting the location, the aesthetic and
functional use of the appliance are primary
concerns; however, vent system routing to the
exterior and access to the fuel supply are also
important.
CAUTION: Due to high temperatures, the ap-
pliance should be located out of traffic and
away from furniture and draperies (Figure 2).
AVERTISSEMENT : En raison des tem-
pératures élevées, l’appareil devrait
être installé dans un endroit où il y a peu
de circulation et loin du mobilier et des
tentures (Figure 2).
The location also should be free of electrical,
plumbing, or other heating/air conditioning
ducting.
These direct-vent appliances are uniquely
suited for installations requiring a utility shelf
positioned above the fireplace. Utility shelves like
these are commonly used for locating television
sets and decorative plants.
The minimum height from the base of the appli-
ance to the underside of combustible materials
used to construct a utility shelf in this fashion
is shown in Figure 7 on Page 9.
Be aware that this is a heat-producing ap-
pliance. Objects placed above the unit are
exposed to elevated temperatures.
Do not insulate the space between the appli-
ance and the area above it.
The appliance should be mounted on a fully
supported base extending the full width and
depth of the unit. The appliance may be located
on or near conventional construction materials.
However, if installed on combustible materials,
(such as carpeting or vinyl tile), a metal or
wood barrier covering the entire bottom surface
must be used.
COLD CLIMATE INSULATION
For cold climate installations, seal all cracks
around the appliance with noncombustible
material and wherever cold air could enter the
room. If the floor is above ground level, it is
especially important to insulate outside chase
cavity between studs and under the floor on
which the appliance rests. Gas line holes and
other openings should be caulked or stuffed
with unfaced fiberglass insulation.
If the fireplace is being installed on a cement
slab in cold climates, a sheet of plywood or
other raised platform can be placed under-
neath to prevent cold transfer to the fireplace
and into the room. It also helps to sheetrock
inside surfaces and tape for maximum air
tightness and caulk firestops.
MANUFACTURED HOME
REQUIREMENTS
This appliance may be installed in an after-
market, permanently located manufactured
home and must be installed in accordance

3" (76 mm) above any horizontal/inclined vent component.
See Step 1 ("FRAMING") on Page 10 for clearance requirements to
the nailing flanges on each side of the unit and any adjacent screw
heads.
The appliance should be mounted on a fully supported base extending
the full width and depth of the unit. The appliance may be located on
or near conventional construction materials; however, if installed on
combustible materials, such as carpeting, vinyl tile, etc., a metal or wood
barrier covering the entire bottom surface must be used.
Min. Height of Combustible Enclosure
To provide for the lowest possible combustible enclosure (or shelf)
surface, the venting should be routed in a way to minimize obstructions
to the space above the appliance. Do not insulate the space between the
appliance and the area above it (see Figure 7).
Wall Finishes / Surrounds / Mantels
Note: Combustible wall finish materials and/or surround materials must
not be allowed to encroach the area defined by the appliance front faces
(black sheet metal). Never allow combustible materials to be positioned
in front of or overlapping the appliance face. See Pages 29 and 30.
Non-combustible materials, such as surrounds and other appliance trim,
may be installed on the appliance front face only if they do NOT cover
any portion of the removable glass panel.
Vertical installation clearances to combustible mantels vary according
to the depth of the mantel. See Figure 8. Mantels constructed of non-
combustible materials may be installed at any height above the appliance
opening.
Note: Use high-temperature paint (rated 175°F or higher) on the underside
of the mantel.

Proper Sizing of Gas Line
Properly size and route the gas supply line
from the supply regulator to the area where the
appliance is to be installed per requirements
outlined in the National Fuel Gas Code, NFPA
54 - latest edition (USA) or CAN/CSA-B149.1
- latest edition (Canada).
IMPORTANT: It is critical that a licensed
installer perform this step strictly per
NFPA.
Never use galvanized or plastic pipe. Refer
to Table 6 for proper sizing of the gas sup-
ply line, if black iron pipe is being used. Gas
lines must be routed, constructed and made
of materials that are in strict accordance with
local codes and regulations. We recommend
that a qualified individual such as a plumber or
gas fitter be hired to correctly size and route
the gas supply line to the appliance. Installing
a gas supply line from the fuel supply to the
appliance involves numerous considerations of
materials, protection, sizing, locations, controls,
pressure, sediment, and more. Certainly no one
unfamiliar and unqualified should attempt sizing
or installing gas piping.
Note:
• All appliances are factory-equipped with
a flexible gas line connector and 1/2 inch
shutoff valve (see Figure 35 on Page 23).
• See Massachusetts Requirements on Page
4 for additional requirements for installations
in the state of Massachusetts in the USA.
• The gas supply line should not be connected
to the appliance until Step 6 (Page 23).
• A pipe joint compound rated for gas should be
used on the threaded joints. Ensure propane
resistant compounds are used in propane
applications. Be very careful that the pipe
compound does not get inside the pipe.
• It is recommended to install a sediment trap
in the supply line as close as possible to
the appliance (see Figure 35 on Page 23).
Appliances using Propane should have a
sediment trap at the base of the tank.
• Check with local building ofcial for local
code requirements (i.e. are below grade
penetrations of the gas line allowed?, etc).

Step 2. ROUTE GAS LINE
NOTICE: For indoor/outdoor installations,
the CONTROL SIDE of the fireplace must
be installed on the INDOOR side.
Route a 1/2" (13 mm) gas line along the inside
of the right side framing as shown in Figures 13
and 14. Gas lines must be routed, constructed
and made of materials that are in strict accor-
dance with local codes and regulations.
All appliances are factory-equipped with a
flexible gas line connector and 1/2 inch shutoff
valve (see Step 6 on Page 23).
The incoming gas line should be piped into the
valve compartment and connected in one of the
two methods as shown in Figure 35 on Page 23.
Step 3. INSTALL VENT SYSTEM
General Information
These instructions should be used as a guide-
line and do not supersede local codes in any
way. Install venting according to local codes,
these instructions, the current National Fuel
Gas Code (ANSI-Z223.1) in the USA or the
current standards of CAN/CGA-B149.1 and
-B149.2 in Canada.
These fireplaces are designed, tested and
listed for operation and installation with,
and only with, Secure Vent™ (SV4.5) Direct-
Vent System Components, manufactured by
Security Chimneys International. These ap-
proved vent system components are labeled
for identification. DO NOT use any other
manufacturer's vent components with these
appliances.
Ensure clearances are in accordance with
local installation codes and the requirements
of the gas supplier.
Dégagement conforme aux codes d’installa-
tion locaux et aux exigences du foumis-
seunde gaz.
Use only approved venting components. See
Approved Vent Components on Page 2.
These fireplaces must be vented directly
to the outside.
The vent system may not service multiple
appliances, and must never be connected to a
flue serving a solid fuel burning appliance. The
vent pipe is tested to be run inside an enclosed
wall (such as a chase). There is no requirement
for inspection openings in the enclosing wall at
any of the joints in the vent pipe.
Venting System
With the appliance secured in framing, de-
termine vent routing and identify the exterior
termination location. The following sections
describe horizontal (exterior wall) vent applica-
tions. A list of approved venting components
is shown on Page 32.
IMPORTANT NOTE REGARDING
PROPANE INSTALLATIONS
Using a propane tank smaller than
100 lbs may create pressure loss and
insufficient fuel delivery, which can
cause sooting, severe delayed ignition,
or other malfunctions (ref. NPFA 58).
Any damage as a result of insufficient
tank size or other improper installation is
NOT covered under the limited warranty.

INNOVATIVE HEARTH PRODUCTS • SEE-THROUGH POWER VENT DV GAS FIREPLACES (MontebelloSTTYN) • INSTALLATION INSTRUCTIONS
VENT SECTION LENGTHS
Determine the number of straight vent sections
required. 4-1/2" (114 mm), 10-1/2" (267 mm),
22-1/2" (572 mm), 34-1/2" (876 mm) and 46-
1/2" (1181 mm) net section lengths are available.
Refer to the Vent Section Length Chart.
Vertical (Offset) Installation
Analyze the vent routing and determine the
quantities of vent sections and number of
elbows required. Refer to Figures 21 and 22
on Page 17 showing vent run requirements to
aid in selecting the type of vertical installation
desired. Vent sections are available in net lengths
of 4-1/2" (114 mm), 10-1/2" (267 mm), 22-1/2"
(572 mm), 34-1/2" (876 mm) and 46-1/2" (1181
mm). Refer to the Vent Section Length Chart
for an aid in selecting length combinations.
Elbows are available in 90° and 45° configura-
tions. Refer to Figure 20 on Page 16 for the
SV4.5 E45 and SV4.5 E90 elbow dimensional
specifications.
Where required, a telescopic vent section
(SV4.5LA) may be used to provide the in-
staller with an option in installing in tight and
confined spaces or where the vent run made
up of fixed length pieces develops a joint in a
undesirable location, or will not build up to the
required length. The SV4.5LA Telescopic Vent
Section has an effective length of from 1-1/2"
(38 mm) to 6-3/4" (171 mm). The SV4.5LA is
fitted with a dimpled end (identical to a normal
vent section component) and a plain end with
3 pilot holes. Slip the dimpled end over the
locking channel end of a standard SV4.5 vent
component the required distance and secure
with three screws.
Maintain a minimum 1" (25 mm) clearance
to combustible materials for all vertical ele-
ments. Clearances for all horizontal elements
are 3" (76 mm) on top, 1" (25 mm) on sides
and 1" (25 mm) on the bottom.

Note: Proper venting support is very important.
The weight of the vent must not be supported
by the fireplace in any degree.
Support the vertical portion of the venting
system every 8 feet (2.4 m) above the fireplace
vent outlet. One method of support is by utiliz-
ing field provided support straps (conventional
plumber's tape). Secure the plumber's tape to
the framing members with nails or screws.
Strap the tape around the vent, securing the
ends of the tape to the framing. If desired,
sheet metal screws #6 x 1/2" length may be
used to secure the support straps to the vent
pipe (see Figure 19).
F. Change vent direction to horizontal/inclined
run. At transition from or to a horizontal/inclined
run, install the SV4.5 E45 and SV4.5 E90 elbows
in the same manner as the straight vent sec-
tions. The elbows feature a twist section to
allow them to be routed about the center axis
of their initial collar section to align with the
required direction of the next vent run element.
Twist elbow sections in a clockwise direction
only so as to avoid the possibility of unlocking
any of the previously connected vent sections
(see Figures 18 and 20).
B. Attach adaptor (with probe) to appliance
collar. Secure Vent™ SV4.5 direct-vent sys-
tem components are unitized concentric pipe
components featuring positive twist lock con-
nections (see Figure 18).
All of the appliances covered in this document
are fitted with collars having locking inclined
channels. The dimpled end of the adaptor fits
over the appliance collar to create the positive
twist lock connection.
The unitized design of the Secure Vent com-
ponents will engage and seal both the inner
and outer pipe without the need for sealant or
screws. If desired a #6 x 1/2" screw may be
used at the joint, but it is not required as the
pipe will securely lock when twisted.
C. Attach vent components to each other. Other
vent sections may be added to the previously
installed section in accordance with the require-
ments shown in Figures 21 and 22 on Page 17.
To add another vent component to a length of
vent run, align the dimpled end over the inclined
channel end of the previously installed section,
adjusting the radial alignment until the four
locking dimples are aligned with the inlets of
the four incline channels of the previous section.
Push the vent component against the previ-
ous section until it fully engages, then twist
the component clockwise running the dimples
down and along the incline channels until they
seat at the end of the channels. This seating
position is indicated by the alignment of the
arrow and dimple as shown in Figure 18.
D. Install firestop/spacer at ceiling. When
using Secure Vent, use SV4.5VF firestop/spacer
at ceiling joists. If there is living space above
the ceiling level, the firestop/spacer must be
installed on the bottom side of the ceiling. If
attic space is above the ceiling, the firestop/
spacer must be installed on the top side of the
joist. Route the vent sections through the framed
opening and secure the firestop/spacer with
8d nails or other appropriate fasteners at each
corner. Remember to maintain 1" (25 mm)
clearance to combustibles, framing members,
and attic or ceiling insulation when running
vertical chimney sections. Attic insulation
shield (H3907) may be used to obtain the
required clearances indicated here. See
installation accessories on Page 32. The gap
between the vent pipe and a vertical firestop
can be sealed with non-combustible caulking.
E. Support the vertical vent run sections.
To attach a vent component to the adaptor on
appliance collar, align the dimpled end over the
adaptor collar, adjusting the radial alignment
until the four locking dimples are aligned with the
inlet of the four inclined channels on the collar
(refer to Figure 18). Push the vent component
against the collar until it fully engages, then twist
the component clockwise, running the dimples
down and along the incline channels until they
seat at the end of the channels.
G. Continue installation of horizontal/inclined
sections. Continue with the installation of the
straight vent sections in horizontal/inclined run
as described in Step C. Install support straps
every 3' (914 mm) along horizontal/inclined
vent runs using conventional plumber’s tape
(see Page 17, Figure 21).
Figure 19
It is important to maintain the required clear-
ances to combustibles: 1" (25 mm) at all sides
for all vertical runs; and 3" (76 mm) at the
top, 1" (25 mm) at sides, and 1" (25 mm) at
the bottom for all horizontal/inclined runs.
NOTICE: It is important to install
horizontal runs on a steady, (i.e., no
“dips”), slightly positive incline of
approximately 1/4 inch rise-per-foot (20
millimeters rise-per-meter) horizontal,
in a direction away from the fireplace.
(Slightly smaller rise-per-foot run ratios
are acceptable.) Use a carpenter’s level
to measure from a constant surface, and
adjust support straps as necessary.

D. Attach vent components to appliance.
To attach a vent component to the appliance
collar, align the dimpled end over the collar,
adjusting the radial alignment until the four
locking dimples are aligned with the inlets of
the four incline channels on the collar (refer
to Figure 18 on Page 16).
Push the vent component against the collar
until it fully engages, then twist the compo-
nent clockwise, running the dimples down
and along the incline channels until they
seat at the end of the channels. The unitized
design of the Secure Vent components will
engage and seal both the inner and outer pipe
elements with the same procedure. Sealant
and securing screws are not required.
E. Attach vent components to each other.
Other vent sections may be added to the
previously installed section in accordance
with the requirements of the vent tables.
To add another vent component to a length
of vent run, align the dimpled end of the
component over the inclined channel end of
the previously installed section, adjusting the
radial alignment until the four locking dimples
are aligned with the inlets of the four incline
channels of the previous section. Push
the vent component against the previous
section until it fully engages, then twist the
component clockwise running the dimples
down and along the incline channels until they
seat at the end of the channels. This seating
position is indicated by the alignment of
the arrow and dimple as shown in Figure
18 on Page 16.
F. Install firestop/spacer at ceiling.
When using Secure Vent, use SV4.5VF fire-
stop/spacer at ceiling joists. If there is living
space above the ceiling level, the firestop/
spacer must be installed on the bottom side
of the ceiling. If attic space is above the ceil-
ing, the firestop/ spacer must be installed
on the top side of the joist. Route the vent
sections through the framed opening and
secure the firestop/spacer with 8d nails or
other appropriate fasteners at each corner.
Remember to maintain 1" (25 mm) clear-
ance to combustibles, framing members,
and attic or ceiling insulation when running
vertical chimney sections.
G. Support the vertical run sections.
On the vertical run, support the venting
system every 8 feet (2.4m) above the fire-
place vent outlet with field provided support
straps (Plumber's tape). Attach the straps
to the vent pipe and secure to the framing
members with nails or screws. See Figure
19 on Page 16.
H. Change vent direction.
At transition from or to a horizontal/inclined
run, install the SV4.5E45 and SV4.5E90
elbows in the same manner as the straight
vent sections. The elbows feature a twist
section to allow them to be routed about the
center axis of their initial collar section to
align with the required direction of the next
vent run element. Twist elbow sections in
a clockwise direction only so as to avoid
the possibility of unlocking any of the
previously connected vent sections (see
Figures 18 and 20 on Page 16).
I. Continue installation of horizontal/inclined
sections.
Continue with the installation of the straight
vent sections in horizontal/inclined run as
described in Step E. Install support straps
every 3 feet (1914 mm) along horizontal/
inclined vent runs using conventional
plumber’s tape.
See Figure 21 on Page 17.
HORIZONTAL (OUTSIDE WALL)
TERMINATION SYSTEM
See Figures 21 and 22 on Page 17 illustrating
the various horizontal venting configurations
that are possible for use with these appliances.
The table in Figure 22 on Page 17 shows each
system’s minimum and maximum vertical and
horizontal length values that can be used to
design and install the vent components in a
variety of applications.
The horizontal vent system terminates through
an outside wall. Building Codes limit or prohibit
terminating in specific areas. Refer to Figure 3
on Page 6 for location guidelines.
Secure Vent™ SV4.5 direct-vent system com-
ponents are unitized concentric pipe compo-
nents featuring positive twist lock connection,
(refer to Figure 18 on Page 16). All of the
appliances covered in this document are fitted
with collars having locking inclined channels.
The dimpled end of the vent components fit
over the appliance collar to create the positive
twist lock connection.
A. Plan the vent run.
Analyze the vent routing and determine the
types and quantities of sections required
4-1/2" (114 mm), 10-1/2" (267 mm), 22-1/2"
(572 mm), 34-1/2" (876 mm) and 46-1/2"
(1181 mm) net section lengths are available.
Make allowances for elbows as indicated in
Figure 20 on Page 16.
Maintain a minimum 1" (25 mm) clearance
to combustibles on the vertical sections.
Clearances for the horizontal runs are; 3"
(76 mm) on top, 1" (25 mm) on sides, and
1" (25 mm) at the bottom.
B. Frame exterior wall opening.
Locate the center of the vent outlet on the
exterior wall according to the dimensions
shown in Figure 11 on Page 11.
Cut and/or frame an opening, 10-1/2" x 12-
1/8" (267 mm x 308 mm) inside dimensions,
with 7-1/2" above center and 5-5/8" below
center.
C. Frame ceiling opening.
If the vertical route is to penetrate a ceiling,
use plumb line to locate the center above
the appliance. Cut and/or frame an open-
ing, 10-1/2" x 10-1/2"(267 mm x 267 mm)
inside dimensions, about this center (refer
to Figure 17 on Page 16).
NOTICE: It is important to install
horizontal runs on a steady, (i.e., no
“dips”), slightly positive incline of
approximately 1/4 inch rise-per-foot (20
millimeters rise-per-meter) horizontal,
in a direction away from the fireplace.
(Slightly smaller rise-per-foot run ratios
are acceptable.) Use a carpenter’s level
to measure from a constant surface, and
adjust support straps as necessary.
Installing Power Vent Termination
J. Assemble vent run to exterior wall.
If not previously measured, locate the cen-
ter of the vent on the exterior wall. Prepare
an opening as described in this manual.
Assemble the vent system to a point where
the terminus of the last section is within 8
inches of the outside wall surface where
the power vent is to be mounted (refer to
Figure 24 on Page 19).
If the terminus of the last section is not
within this distance, use the telescopic vent
section SV4.5LA, as the last vent section.
For wall thicknesses greater than that shown
in Figure 24 on Page 19, refer to Table 8
(Page 19) for the additional venting compo-
nents needed (in addition to the termination
and adaptor) for a particular range of wall
thicknesses.
K. Attach termination adaptor.
Attach the adaptor (SV4.5RCH, provided
with the power vent kit) to the vent section
telescoping vent section, or elbow, as shown
in Figures 23 and 24 on Page 19 in the same
manner as any SV4.5 vent component.

NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.
L. Install Firestop/Spacer at exterior wall.
Install SV4.5HF Firestop/Spacer, provided
with the power vent kit, over the opening at
the exterior side of the framing, long side
up, with the 3 inch spacer clearance at the
top as shown in Figure 23, and nail into
place.
(The Firestop/Spacer may also be installed
over the opening at the interior side of the
framing).
M. Install the Power Vent termination.
For the last step, from outside the exterior
wall, slide the collars of the termination onto
the adaptor (the outer inside the outer and
the inner outside the inner) until the termi-
nation seats against the exterior wall sur-
face to which it will be attached. Orient the
housing of the termination with the arrow
pointed upwards. Secure the termination
to the exterior wall. The termination must
not be recessed into the exterior wall or
siding by more that the 1-1/4” (32 mm) as
shown in Figure 24.Figure 23: Installing Power Vent Horizontal Termination

The Power Vent termination has been
designed to perform in a wide range of
weather conditions. Our terminations meet
or exceed industry standards.
When selecting the location of your ter-
mination, do not place the termination
where water from eaves and adjoining
roof lines may create a heavy flow of
cascading water onto the terminations. If
the termination must be placed where the
possibility of cascading water exists, it is
the responsibility of the builder to direct
the water away from the termination cap
by using gutters or other means.
Take care to carefully follow the Instal-
lation Instructions for the termination,
including the use of silicone caulking
where required.

Step 4. FIELD WIRING
CAUTION: Label all wires prior to disconnection when servic-
ing controls. Wiring errors can cause improper and dangerous
operation.
ATTENTION: Au moment de l'entretien des commandes,
étiquetez tous les fils avant de les débrancher. Des erreurs
de cáblage peu-vent entraîner un fonctionnement inadéquat
et dangereux.
Verify proper operation after servicing.
S'assurer que l'appareil fonctionne adé-quatement une fois
l'entretien terminé.
CAUTION: Ground supply lead must be connected to the wire
attached to the green ground screw located on the outlet box.
See Figures 32 and 33 on Page 22. Failure to do so will result
in a potential safety hazard. The appliance must be electrically
grounded in accordance with local codes or, in the absence of
local codes, the National Electrical Code, ANSI/NFPA 70-latest
edition (In Canada, the current CSA C22-1 Canadian Electrical
Code).

Route Wiring
NOTE: Electrical wiring must be performed by a qualified electrician.
• Install the strain relief in the hole provided on the right side of replace
for the electrical wiring (refer to Figure 25).
Standard Instruction (For use when access to the termination is
difficult because of height or other reasons).
• Locate a locally procured electrical junction box within reach of the
termination wiring pigtail (refer to Figure 28 on Page 21) and route
the pigtail to the junction box as the termination is installed.
• Route 14 gauge AWG grounded Romex wiring (not provided) from
the fireplace to the just installed junction box close to the termina-
tion. Ensure the wiring is safety plated to prevent damage by framing
nails and finish drywall screws. Route the wire into the lower control
compartment and cut to length before installing the terminals. Install
provided wiring hardware on the ends of the Romex wire.
• Refer to Figure 29 on Page 21 and install the electrical hardware on
the ends of the Romex wiring. Male terminals on the Black and White
wires, and ring terminals on the ground wire.
• Using standard electrical practices and the terminals provided, con-
nect the three wires of the Romex cable to the termination pigtail
within the Electrical junction box. Ensure ground.
• The replace end of the Romex will be addressed in Connecting The
Power Vent To The Fireplace Control System.
