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.
Due to high temperatures, the appliance should be located out of traffic and away from furniture
and draperies (Figure 3).
En raison des températures élevées, l’appareil devrait être installé dans un endroit où il y a
peu de circulation et loin du mobilier et des tentures (Figure 3).
The location should also 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
directly above the fireplace. Utility shelves like these are commonly used for locat-ing television
sets and decorative plants.
COLD CLIMATE INSULATION
For cold climate installations, seal all cracks
around your appliance with noncombustible
material and wherever cold air could enter
the room. It is especially important to insulate
outside chase cavity between studs and under
floor on which appliance rests, if floor is above
ground level. Gas line holes and other open-
ings 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
otherraised platform can be placed underneath
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.

MINIMUM CLEARANCES TO COMBUSTIBLES
Appliance And Vent Clearances
The appliance is approved with zero clearance to combustible materials on all sides (as detailed
in Table 5), with the following exception: When the unit is installed with one side flush with a
wall, the wall on the other side of the unit must not extend beyond 6" from the front edge of
the unit as shown in Figure 9.
*Note: 3" (75 mm) above any horizontal/inclined vent component.
**Note: See Page 10, Step 1 and Figure 12 for clearance requirements to the nailing ange
located at each side of the unit and any screw heads adjacent to it.
- A hearth extension is not
required with this appliance. If a hearth exten-
sion is used, do not block the lower control
compartment door. Any hearth extension used
is for appearance only and does not have to
conform to standard hearth extension instal-
lation requirements.
Shelf Height - To provide for the lowest pos-
sible shelf surface, use the alternate rear vent
outlet,theventingattachedtothetopventshould
be routed in a way to minimize obstructions to
the space above the appliance. Do not insulate
Figure 8). The minimum height
from the base of the appliance to the underside
of combustible materials used to construct a
utility shelf in this fashion is shown in Figure 8.
The appliance should be mounted on a fully
supported base extending the full width and
depth of the unit. The appliance may be located
onornearconventionalconstructionmaterials.
However, if installed on combustible materials,
such as carpeting, vinyl tile, etc., a metal or
woodbarriercoveringtheentirebottomsurface
must be used.
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
face (black sheet metal). Never allow combus-
tible materials to be positioned in front of or
overlapping the appliance face (see Figure 66
on Page 36) and Figure 9 on page 9.
Minimum clearance requirements include any
projections such as shelves, window sills,
mantels, etc. above the appliance.
Non-combustible materials, such as surrounds
and other appliance trim, may be installed on
the appliance face with these exceptions: they
must not cover any portion of the removable
glass panel or control compartment.
Vertical installation clearances to combustible
mantels vary according to the depth of the
mantel. See Figure 7. Mantels constructed of
non-combustible materials may be installed
at any height above the appliance opening;
however, do not allow anything to hang below
the fireplace hood.
Note: We recommend the use of high tem-
perature paint (rated 175° F or higher) on the
underside of the mantel.

IMPORTANT: If propane is used, be aware that
if tank size is too small (i.e. under 100-lbs, if
this is the only gas appliance in the dwelling.
Ref. NPFA 58), there may be loss of pressure,
resulting in insufficient fuel delivery (which
can result in sooting, severe delayed ignition
or other malfunctions). Any damage resulting
from an improper installation, such as this,
is not covered under the limited warranty.
Step 3. PREPARING THE APPLIANCE

Proper Sizing of Gas Line
Properly size and route the gas supply line from
thesupply regulator to the area wheretheappli-
anceistobeinstalledperrequirementsoutlined
in the National Fuel Gas Code, NFPA 54—latest
edition (USA) or CAN/CSA-B149.1—latest edi-
tion (Canada).
Never use galvanized or plastic pipe. Refer to
Table 6 for proper sizing of the gas supply 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
andregulations. Werecommendthataqualified
individual such as a plumber or gas fitter be
hired to correctly size and route the gas supply
line to the appliance.
Also see Figures 13 and 14.
Figure 21 - Route Gas Line
Step 2. ROUTING GAS LINE
Route a 1/2" (13 mm) gas line to the left side
of the appliance as shown in Figure 21. Gas
lines must be routed, constructed and made
of materials that are in strict accordance with
local codes and regulations. All appliances
are factory-equipped with a flexible gas line
connector and 1/2 inch shutoff valve.

Use only approved venting components. See Approved Vent
Components on Page 4.
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.

Secure Flex, use SF4.5VF firestop/spacer. If
there is living space above the ceiling level, the
firestop/spacermust be installed on the bottom
side of the ceiling. If attic space is above the

may help to obtain the required clearances
indicated here. See installation accessories
tables on pages 38 and 39.
Analyze the vent routing and determine the
quantities of vent sections and number of
elbowsrequired.Refer toVerticalVentFigures
and Tables on page 18 to select 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
Effective Vent Length Chart Table 7 on page
18 for an aid in selecting length combinations.
Elbows are available in 90° and 45° configura-
tions. Refer to Figure 30 for the SV4.5E45 and
SV4.5E90 elbow dimensional specifications.
Where required, a telescopic vent section
may be used to provide the installer
withanoption 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 7-1/2" (191 mm). The SV4.5LA is fitted with
a locking inclined channel end (identical to a
normalventsectioncomponent) andaplainend
with 3 pilot holes. Slip the plain end over the
locking channel end of a standard SV4.5 vent
component the required distance and secure
with three screws.
combustible materials for all vertical elements.
A. Frame ceiling opening - Use a plumb line
from the ceiling above the appliance to locate
center of the vertical run. Cut and/or frame an
opening, 10-1/2" x 10-1/2" (267mm x 267mm)
inside dimensions, about this center mark
(Figure 26 ).
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 inlet of
the four inclined channels on the collar (refer to
Figure 27 ). 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. The unitized
design of the Secure Vent components will
engage and seal both the inner and outer pipe
withouttheneedforsealantorscrews. Ifdesired
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.
Note: An elbow may also be attached to the
appliance collar. Attach in the same manner
as you would a vent section.
B. Attach vent components to appliance - Se-
cure Vent®SV4.5 direct vent system compo-
nents are unitized concentric pipe components
featuring positive twist lock connections (see
Figures 27 and 28 ).
All of the appliances covered in this document
are fitted with collars having locking inclined

ponents fit over the appliance collar to create
the positive twist lock connection.

If the vent system extends more than 5' (1.5
m) above the roof flashing, stabilizers may be
necessary. Additional screws may be used at
section joints for added stability. Guide wires
may be attached to the joint for additional sup-
port on multiple joint configurations.
G.Continueinstallationofhorizontal/inclined
sections - Continue with the installation of the
straight vent sections in horizontal/inclined run
as described in Step C. Install support straps
every 5' (1.52 m) along horizontal/inclinedvent
runs using conventional plumber’s tape. It is
very important that the horizontal/inclined

meter) of horizontal vent.Use a carpenter’s
level to measure from a constant surface and
adjust the support straps as necessary.
It is important to maintain the required clear-
the bottom for all horizontal/inclined runs.
F.Changeventdirectiontohorizontal/inclined
run - At transition from or to a horizontal/in-
clined 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.
only so as to avoid the possiblity of unlocking
anyofthepreviouslyconnectedventsections.
See Figure 30.
E. Support the vertical vent run sections -
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 (2.4m) 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
theframingmemberswithnailsorscrews.Loop
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. Refer to
