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 the front edge of the unit.
In addition, when the unit is recessed, the side walls surrounding the unit must not extend beyond
the front edge of the unit (see Figure 3).

*Note: 3 in. (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.

Mantel Depth

Top of
Appliance

inches (millimeters)

Hearth Extension - A hearth extension is not

required with this appliance. If a hearth exten­sion 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 instal­lation requirements.

Shelf Height - To provide for the lowest pos-

sible shelf surface, use the alternate rear vent
outlet, the venting attached to the top vent 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 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
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.

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.

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 tem­perature paint (rated 175° F or higher) on the
underside of the mantel.

DETAILED INSTALLATION STEPS

The appliance is shipped with all gas controls
and components installed and pre-wired.

1 - Remove the shipping carton.
2 - Remove the top radiant panel (refer to
Figure 11 ).
3 - Lift the pressure relief plates and remove
the cardboard from underneath each of
them.
4 - Open the control compartment access

panel, by actuating the spring-loaded magnetic
catches securing the panel, gently depressing
the outer top corners of the panel until the
catches "pop" the panel free and allowing it to
swing out and down to open.
5 - Remove the bottom control compartment
access panel by compressing the spring­loaded hinge pin on the left side until it
disengages from the left cabinet panel hole.
Pull the panel away from the fireplace. See

Figure 56 on page 30.

6 - Remove the modesty panel by pulling the
bottom right corner of the modesty panel out
slightly to disengage the snap-fit feature; lift the
modesty panel by the tab on the panel's right
end, pull the right end of the panel away from
the cabinet and then pull the panel diagonally
out of the left side cabinet panel slots. (In
the above procedure, reverse the words "left"
and "right" for EDVCR models). Remove the
modesty panel carefully, so that none of the
wires become loose or disconnected.
7 - Open the two latches (located under the
firebox floor) securing the glass enclosure
panel. Remove the panel by tilting it outward
at the bottom and lifting it up. Set the door
aside protecting it from inadvertent damage.

See Figure 63 on page 34.

TYPICAL INSTALLATION SEQUENCE

The typical sequence of installation is outlined
below. However, each installation is unique
and may result in variations to the steps
described.

See the page numbers references in the follow­ing steps for detailed procedures.

Step 1. (Page 10) Construct the appliance
framing. Position the appliance within the
framing and secure with nailing brackets (refer
to Figure 12).

a. Millivolt Appliances – Install the operating
control switch (not factory provided) and bring
in electrical service line for forced air-circulating
blower (optional equipment).
b. Electronic Appliances – Field wire and install
operating control switch.

Step 6. (Page 28) Install blower kit (optional
equipment).

Step 7. (Page 28) Make connection to gas
supply.

Step 8. (Page 29) Verifying appliance opera-
tion.

Step 9. (Page 30) Install the logs, decorative
volcanic stone and glowing embers.

Before proceeding it may be helpful to remove
the log set form the firebox and remove the
embers and volcanic stone from the control
compartment. Refer to the following steps:

1. Remove the front glass enclosure panel

(see Removing and Installing Glass Enclosure
Panels on Page 34).

2. Remove log set box from firebox. Next,
remove embers and volcanic stone from con­trol compartment. Handle logs carefully to

prevent breakage.

Step 1. FRAMING

Frame these appliances as illustrated in Figures

13 (EDVST), 14 (EDVPF), 15 (EDVCL) or 16

(EDVCR). All framing details must allow for
a minimum clearance to combustible framing
members as shown inTable 5 on page 9. If the
appliance is to be elevated above floor level, a
solid continuous platform must be constructed.
Headers may be in direct contact with the
appliance top spacers but must not be sup­ported by them or notched to fit around them.
All construction above the appliance must be
self supporting, DO NOT use the appliance for
structural support.

Figure 12 - Nailing Flanges

NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.

Side Nailing Flanges

The fireplace should be secured to the framing
at the side(s) and/or rear of the unit using the
factory-provided nailing flanges. Install the
nailing flanges - 8 (EDVST), 4 (EDVPF, EDVCL
and EDVCR) - as shown in Figure 12 using the
existing screws.

Position the fireplace within the framing. When
required, the flanges may be bent 90 degrees by
hand or with the assistance of a hammer. Use
wood screws to secure the nailing flanges to
the framing. See Table 5 on page 9 for clear-
ances of framing members to cabinet parts in
the nailing flange area. The nailing flange itself
is exempt from these clearances.

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).

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
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.

Notes:

• All appliances are factory-equipped with

a flexible gas line connector and 1/2 inch
shutoff valve.

• 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 7 (Page 28).

• 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. 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).

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
VENT COLLAR

WARNING

Failure to reinstall and securely
tighten vent seal cap screws
could result in leakage of flue
products into the living space.
Vent seal cap must remain
securely installed on unused
vent collar. Failure to do so
could result in leakage of flue
products into living space.

REMOVE VENT SEAL CAP
(From the vent that will be used only)

Top Vent Installations - See Figure 22
Side Vent Installations - See Figure 23

Preparing the Appliance Vent Collar

Each of the appliances' two vent collars are
sealed with a seal cap which must be removed
from the vent collar being used. Refer to Figure
22 for top vent installations and Figure 23 for
side vent installations and the following steps to
prepare the appropriate collar for use.

From the vent collar being used, remove the
two screws securing the vent seal cap. Twist
the cap counterclockwise. Pull it away from
the appliance and discard, along with the piece
of insulation.

VENT RESTRICTOR INSTALLATION

A vent restrictor may be needed when vertically terminating the vent

system above the roof (when using the appliance top vent), install a vent

If needed, install the restrictor as shown, either from inside or outside the

restrictor in the top vent of the fireplace outlet.

unit, in the inner fireplace collar.

Restrictor

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.

Installation of Vent Restrictor

A vent restrictor may be needed with this appliance. The restrictor is
installed in the appliance top flue outlet as shown in Figure 24, either
before adding vent, from above, or after installation of vent from below,
within the firebox. The restrictor is self securing through a positive
friction fit.

Determine the venting for the appliance. If the vent run will include at

least 8 feet of vertical rise, then install the restrictor in the appliance
collar before connecting any vent (Refer to Figure 24 ). Place the

restrictor inside the appliance vent collar and press in place.

Note: The restrictor is included within the firebox.

Select Venting System - Horizontal or Vertical

With the appliance secured in framing, determine vent routing and identify
the exterior termination location. The following sections describe vertical
(roof) and horizontal (exterior wall) vent applications. Refer to the section
relating to your installation. A list of approved venting components are

shown on Pages 38 and 39.

VERTICAL TERMINATION SYSTEMS (ROOF)

See Figure 25 and Figures 35 through 39
on Pages 19 and 20 and their associated
Vertical Vent Tables which illustrate the various
vertical venting configurations that are possible
for use with these appliances. Secure Vent™
pipe applications are shown in these Figures;
Secure Flex™ pipe may also be used. A Vertical
Vent Table summarizes 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.

Both these vertical vent systems terminate
through the roof. The minimum vent height
above the roof and/or adjacent walls is speci­fied in ANSI Z223.1-(latest edition) (In Canada,
the current CAN/CSA-B149.1 installation code)
by major building codes. Always consult your
local codes for specific requirements. A general
guide to follow is the Gas Vent Rule (refer to

Figure 5 on Page 6).

Vertical (Straight) Installation

(Figure 25)

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 (see Tables on this page and
Page 38 - Rigid Vent Sections). Plan the vent
lengths so that a joint does not occur at the
intersection of ceiling or roof joists. 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 Vertical Vent Figures
and Tables on page 16 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
16 for an aid in selecting length combinations.

Elbows are available in 90° and 45° configura­tions. Refer to Figure 30 for the SV4.5E45 and
SV4.5E90 elbow dimensional specifications.

Where required, a telescopic vent section
(SV4.5LA) may be used to provide the installer
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 7-1/2" (191 mm). The SV4.5LA is fitted with
a locking inclined channel end (identical to a
normal vent section component) and a plain end
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.

Maintain a minimum 1" (25 mm) clearance to
combustible materials for all vertical elements.
Clearances for all horizontal elements are 3"
(76 mm) on top, 1" (25 mm) on sides and 1"
(25 mm) on the bottom.

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 ).

B. Attach vent components to appliance ­Secure 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
channels. The dimpled end of the vent com­ponents fit over the appliance collar to create
the positive twist lock connection.

Figure 27

Figure 28

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
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.

Note: An elbow may also be attached to the
appliance collar. Attach in the same manner
as you would a vent section.

NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.

C. Attach vent components to each other

- Other vent sections may be added to the

previously installed section in accordance with
the requirements of the vertical vent figures
and tables. 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 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 28.

D. Install firestop/spacer at ceiling (Figure

29 ) - When using Secure Vent, use SV4.5VF
firestop/spacer at ceiling joists; when using
Secure Flex, use SF4.5VF firestop/spacer. 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
(96K94) may be used to obtain the required
clearances indicated here. See installation
accessories tables on pages 38 and 39.

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.

Twist elbow sections in a clockwise direction
only so as to avoid the possiblity of unlocking
any of the previously connected vent sections.

See Figure 30.

H. Frame roof opening - Identify location for
vent at the roof. Cut and/or frame opening per
Roof Framing Chart and Figure 31.

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 utiliz­ing field provided support straps (conventional
plumber's tape). Secure the plumber's tape to
the framing members with nails or screws. 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

Figure 29.

I. Install the roof flashing - Extend the vent
sections through the roof structure. Install the
roof flashing over the vent section and posi­tion such that the vent column rises vertically
(use carpenters level) (Figure 32 ). Nail along
perimeter to secure flashing or adjust roofing
to overlap the flashing edges at top and sides
only and trim where necessary. Seal the top
and both sides of the flashing with waterproof
caulking.

Figure 33

K. Install the vertical termination - The final
step involves installation of the SV4.5CGV-1
Vertical Termination. Extend the vent sections
to the height as shown in the "Vertical vent ter­mination section" on page 6. The SV4.5CGV-1
Vertical Termination (Figure 34 ) installs in the
exact same fashion as any other Secure Vent
section. Align the termination over the end of
the previously installed section, adjusting the
radial alignment until the four locking dimples
of the termination are aligned with the inlets of
the four incline channels of the last vent section.
Push the termination down until it fully engages,
then twist the termination clockwise running the
dimples down and along the incline channels
until they seat at the end of the channels.

18

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 5' (1.52 m) along horizontal/inclined vent
runs using conventional plumber’s tape. It is

very important that the horizontal/inclined
run be maintained in a straight (no dips) and
slightly elevated plane in a direction away
from the fireplace 1/4" per foot (20 mm per

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 clear­ances 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.

Figure 32

J. Install the storm collar - Install the storm
collar, supplied with the flashing, over the vent/
flashing joint. See Figure 33. Loosen the storm
collar screw. Slide collar down until it meets
the top of the flashing. Tighten the adjusting
screw. Apply non-combustible caulking or
mastic around the circumference of the joint
to provide a water tight seal.

NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.

Figure 34

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 sup­port on multiple joint configurations.

Note: Secure Vent (rigid vent pipe) is shown
in the figures; Secure Flex (flexible vent pipe)
may also be used.

Note: It is very important that the horizontal/
inclined run be maintained in a straight (no
dips) and recommended to be in a slightly

elevated plane, in a direction away from the
fireplace of 1/4" rise per foot (20 mm per meter)

which is ideal, though rise per foot run ratios
that are smaller are acceptable all the way down
to at or near level.

Note: SV4.5VF (Secure Vent), SF4.5VF (Secure
Flex) firestop/spacer must be used anytime vent
pipe passes through a combustible floor or ceil­ing. SV4.5HF (Secure Vent), SF4.5HF (Secure
Flex)firestop/spacer must be used anytime vent
pipe passes through a combustible wall.

Note: Two 45 degree elbows may be used in
place of one 90 degree elbow. The same rise
to run ratios, as shown in the venting figures
for 90 elbows, must be followed if 45 degree
elbows are used.

Note: An elbow is acceptable as 1 foot of
vertical rise, except where an elbow is the
only vertical component in the system. (See
Figure 44 on page 23 ).

HORIZONTAL (OUTSIDE WALL)
TERMINATION SYSTEM

Figures 40, and Figures 43 to 48 on pages
23 to 25 and their associated Horizontal Vent

Table illustrate the various horizontal venting
configurations that are possible for use with
these appliances. Secure Vent pipe applications
are shown in these figures; Secure Flex pipe
may also be used. A Horizontal Vent Table sum­marizes 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.

Both of these horizontal vent systems terminate
through an outside wall. Building Codes limit or
prohibit terminating in specific areas. Refer to

Figure 6 and page 7 for location guidelines.
Secure Vent SV4.5 direct vent system components

are unitized concentric pipe components featuring
positive twist lock connection, (refer to Figure 28
on page 17). 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. It is recommended
that you plan the venting so that a joint does not
occur in the ceiling or roof joists. Allow for elbows
as indicated in Figure 30 on page 18.

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 Figures
13, through 16 on page 11. Cut and/or frame an
opening, 10-1/2" x 12-1/8" (267 mm x 308mm)
inside dimensions, about this 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 opening, 10-1/2" x 10-1/2" (267 mm x 267
mm) inside dimensions, about this center (refer
to Figure 26 on page 17 ).

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 27 on page 17 ).

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.

Figure 40 -TYPICAL HORIZONTAL VENT INSTALLATION

The unitized design of the Secure Vent compo-
nents will engage and seal both the inner and
outer pipe elements with the same procedure.
Sealant and securing screws are not required.

Note: An elbow may also be attached to the
appliance collar. Attach in the same manner
as you would a vent section.

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 28 on page 17.

F. Install firestop/spacer at ceiling -

When using Secure Vent, use SV4.5VF firestop/
spacer at ceiling joists; when using Secure Flex,
use SF4.5VF firestop/spacer. 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.

G. Support the vertical run sections -

On the vertical run, support the venting sys­tem every 8 feet (2.4m) above the fireplace
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 29 on page 17.

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 possiblity of unlocking any
of the previously connected vent sections.
See Figure 30 on page 18.

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 5 ft. (1.52 m) along horizontal/inclined
vent runs using conventional plumber’s tape.
See Figure 40, it is very important that the

horizontal/inclined run be maintained in a
straight (no dips) and recommended to be in
a slightly elevated plane, in a direction away
from the fireplace of 1/4" rise per foot (20 mm

per meter) which is ideal, though rise per foot
run ratios that are smaller are acceptable all the
way down to at or near level. 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 clear­ances 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

to point where the terminus of the last section
is within 7 in. (178 mm) to 11-1/4 in. (286
mm) inboard of the exterior surface to which
the SV4.5 HT termination is to be attached, see
Figure 42. 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 42, refer to Table 8 on page 23. This table
lists the additional venting components needed
(in addition to the termination and adapter) for
a particular range of wall thicknesses.

K. Attach termination adapter - Attach the
adapter (adapter - SV4.5RCH - provided with the
termination) to the vent section or telescoping
vent section), elbow or appliance collar as shown
in Figure 41 in the same manner as any SV4.5
vent component (refer to Step E).

L. Install Firestop/Spacer at exterior wall

- When using the square termination, install

SV4.5HF (Secure Vent), SF4.5HF (Secure Flex)
Firestop/Spacer 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

41, and nail into place.

M. Install the desired termination -

1. Install the square termination (SV4.5HT-2)-

For the last step , from outside the exterior wall,
slide the collars of the termination onto the
adapter (the outer over the outer and the inner
inside the inner) until the termination seats
against the exterior wall surface 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

horizontal termination must not be recessed
into the exterior wall or siding by more than

the 1-1/4" (32 mm) as shown in Figure 42.

IMPORTANT: The vent termination is hot
while in operation and for a period of
time following the use of the fireplace.
To prevent contact with hot surfaces,
we recommend the use of a Termina-
tion Guard. See Page 39. This can be
purchased at your local dealer.

Figure 42

Horizontal terminations have been designed to perform in a wide range of weather
conditions. Our terminations meet or exceed industry standards.

When selecting the locations of your horizontal terminations, do not place the termination
where water from eaves and adjoining rooflines may create a heavy flow of cascading water
onto the termination cap. If the cap 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 installation instructions for the termination, including the
use of silicone caulking where required.

Note: Two 45 degree elbows may be used in place of one 90 degree
elbow. The same rise to run ratios, as shown in the venting figures for
90 elbows, must be followed if 45 degree elbows are used.

Note: It is very important that the horizontal/inclined run be maintained

in a straight (no dips) and recommended to be in a slightly elevated
plane, in a direction away from the fireplace of 1/4" rise per foot (20

mm per meter) which is ideal, though rise per foot run ratios that are
smaller are acceptable all the way down to at or near level.

Note: SV4.5VF (Secure Vent), SF4.5VF (Secure Flex) firestop/spacer must
be used anytime vent pipe passes through a combustible floor or ceiling.

SECURE FLEX KITS AND COMPONENTS

Secure Flex venting kits and components may
be used in any venting application where rigid
Secure Vent (SV4.5) direct vent components
can be used. All restrictions, clearances and
allowances that pertain to the rigid piping apply
to the flexible venting. Secure Flex kits may

not be modified; also, under no circumstances
may separate sections of flex pipe be joined
together. Secure Flex kits may be added to
the end of a vent run made up of rigid Secure
Vent (SV4.5) vent sections provided that doing

so does not violate any of the venting length,
height, routing, horizontal to vertical ratio re­quirements or clearance considerations detailed
in this manual.

Secure Flex kits come with an included adapter
that can be fitted to the appliance collar or the
inclined channel end of the last Secure Vent
(SV4.5) vent section in a rigid system in the
exact same fashion as any other Secure Vent
section. Align the dimpled end of the adapter
over the previously installed section or appliance
collar, adjusting the radial alignment until the

TEST ALL CONNECTIONS FOR GAS LEAKS
(FACTORY AND FIELD):

WARNING

Never use an open flame to
check for leaks.

Step 7. CONNECTING GAS LINE

Make gas line connections. All codes require a
shut-off valve mounted in the supply line. Figure
55 illustrates two methods for connecting the
gas supply. The flex-line method is acceptable
in the U.S., however, Canadian requirements
vary depending on locality. Installation must
be in compliance with local codes. A sediment
trap is recommended in the gas piping within
the home to prevent moisture and debris in the
line from damaging the valve.

These appliances are equipped with a gas flex
line for use (where permitted) in connecting the
unit to the gas line. A gas flex line is provided
to aid in attaching the direct vent appliance to
the gas supply. The gas flex line can only be
used where local codes permit. The flex line
is rated for both natural and propane gas. A
manual shut off valve is also provided with
the flex line.

The gas control valve is located in the lower
control compartment.

To access the valve open the lower control
compartment door (see Figure 56 ) by pushing
in the right top corner of the door. (The door
is hinged at the bottom.) Remove the bottom
compartment door by sliding the hinge pin,
located at the door’s left side, to the right until
it disengages from the left corner post hole.
Pull the door diagonally to the left, away from
the fireplace.

The lower control compartment door on the
side opposite the valve lifts on and off.

The millivolt control valve has a 3/8"
(10 mm) NPT thread inlet port. The electronic
control valve has a 1/2" (13 mm) NPT thread
inlet port and is fitted with a 1/2" x 3/8" (13 mm x
10 mm) NPT fitting.

28

Secure all joints tightly using appropriate
tools and sealing compounds (ensure propane
resistant compounds are used in propane
applications).

All codes require a shut-off valve mounted
in the supply line. The orientation of the
shut-off valve should face the front. Figure
55 illustrates two methods for connecting the
gas supply. A sediment Trap is recommended
to prevent moisture and debris in the gas line
for damaging the valve.

Turn on gas supply and test for gas leaks, us­ing a gas leak test solution (also referred to as
bubble leak solution).

Note: Using a soapy water solution is an
effective leak test solution but it is not recom­mended, because the soap residue that is left
on the pipes/fittings can result in corrosion
over time.

A. Light the appliance (refer to the lighting

instructions label in the control compartment
or in the Care and Operation Instructions
manual).

B. Brush all joints and connections with the gas

leak test solution to check for leaks. If bubbles
are formed, or gas odor is detected, turn the
gas control knob (off/pilot/on) to the “OFF”
position. Either tighten or refasten the leaking
connection, then retest as described above.

C. When the gas lines are tested and leak free, be

sure to rinse off the leak testing solution.

Step 8. VERIFYING APPLIANCE OPERA­TION

Turn on burner and observe the individual
tongues of flame on the burner. Make sure
all ports are open and producing flame evenly
across the burner. If any ports are blocked, or
partially blocked, clean out the ports.

With gas line installed run initial system
checkout before closing up the front of the unit.
Follow the pilot lighting instructions provided
in the Care and Operation Instructions manual.
For piezo igniter location see Figure 56 on
Page 30 (millivolt appliances only).

Note: Lighting Instructions are also found on
the literature tag tied to the gas piping next
to the gas valve. To access the tag, open the
lower control compartment door (Figure 56)
by pushing in simultaneously the left and right
top corners of the door. (The door is hinged at
the bottom). Remove the bottom compartment
door by sliding the hinge pin, located at the
door’s left side, to the right until it disengages
from the left corner post hole. Remove the
modesty panel. To remove the modesty panel,
slide the panel forward until it contacts the
cabinet bottom panel, then lift straight up and
tilt forward. Remove the modesty panel care­fully, so that none of the wires become loose
or disconnected.

When first lighting the appliance, it will take a
few minutes for the line to purge itself of air.
Once purging is complete, the pilot and burner
will light and operate as indicated in the instruc­tion manual.

Subsequent lighting of the appliance will not
require such purging. Inspect the pilot flame (re­move logs, if necessary, handling carefully).

Figure 56

Millivolt Appliance Checkout

The pilot flame should be steady, not lifting
or floating. Flame should be blue in color with
traces of orange at the outer edge.

The top 3/8" (10 mm) at the pilot generator
(thermopile) and the top 1/8" minimum (tip)
of the quick drop out thermocouple should be
engulfed in the pilot flame.

The flame should project 1" (25 mm) beyond the
hood at all three ports (see Figure 57). Replace
logs if removed for pilot inspection.

To light the burner; turn “ON” the remote wall
switch and rotate the gas valve control knob
counterclockwise to the “ON” position (“ON”
will be at the top side of the valve).

To light the burner, turn ‘ON’ the unit mounted

Figure 63

Step 11. BURNER ADJUSTMENTS

Flame Appearance and sooting

Proper flame appearance is a flame which is
blue at the base and becomes yellowish-orange
in the body of the flame.

When the appliance is first lit, the entire
flame may be blue and will gradually turn
yellowish-orange during the first 15 minutes
of operation. If the flame remains blue, or if
the flame is orange with evidence of sooting
(black tip), the air shutter opening may need
to be adjusted.

If the air shutter opening is closed too far,
sooting may develop. Sooting is indicated by
black puffs developing at the tips of very long
orange flames. Sooting results in black deposits
forming on the logs, appliance inside surfaces
and on exterior surfaces adjacent to the vent
termination.

Sooting is caused by incomplete combustion
in the flames and lack of combustion air enter­ing the air shutter opening. To achieve a warm
yellowish-orange flame with an orange body
that does not soot, the shutter opening must be
adjusted between these two extremes.

Air Shutter Adjustment Guidelines

• If there is smoke or soot present, rst check

the log set positioning to ensure that the
flames are not impinging on any of the logs.
If the log set is properly positioned and a
sooting condition still exists, then the air
shutter opening should be increased.

• The more offsets in the vent system, the larger

the air shutter opening will need to be.

• An appliance operated with the air shutter

opened too far, may have flames that appear
blue and transparent. These weak, blue and
transparent flames are termed anemic.

• Propane models may exhibit ames which

candle or appear stringy. If this is present
and persists, adjust the air shutter to a more
closed position, then operate the appliance
for a few more minutes to ensure that the
flame normalizes and the flames do not
appear sooty.

The following chart is provided to aid you in
achieving the correct air shutter adjustment
for your installation.

WARNINGS

Glowing Embers (Rockwool)

• Air shutter adjustment should

only be performed by a quali­fied professional service tech­nician.

• Ensure front glass panel are

in place and sealed during
adjustment.

CAUTIONS

• Soot will be produced if the

air shutter is closed too much.
Any damage due to sooting,
resulting from improperly
setting the air shutter, is not
covered under the warranty.

• The air shutter door and

nearby appliance surfaces
are hot. Exercise caution to
avoid injury while adjusting
flame appearance.

Figure 64 - Burner Flame Appearance

1. Refer to Figure 64 for proper flame appearance. To adjust the flame, rotate the adjustment rod toward the back or toward the front of the

fireplace (rod located in the lower control area). Position the air shutter to the factory setting as shown in the table in Figure 65.

2. Light appliance (follow lighting procedure on lighting label in control compartment or see the Care and Operation Manual).

3. Allow the burner to operate for at least 15 minutes while observing the flame continuously to ensure that the proper flame appearance has been

achieved. If the following conditions are present, adjust accordingly.

• If ame appears weak or sooty, adjust the air shutter, incrementally, to a more open position until the proper ame appearance is achieved.

• If ame remains blue, adjust the air shutter, incrementally, to a more closed position until the proper ame appearance is achieved.

4. Leave the control knob (off/pilot/on) in the ON position and the burner OFF/ON switch OFF (and remote switches, if applicable).

5. When satisfied that the burner flame appearance is normal, re-install the lower control compartment door then proceed to finish the installation.

STEP 13. ATTACHING SAFETY-IN-OPERATION WARNINGS
It is the installers responsibility to ensure these warnings are properly affixed during installation. These warning labels are a

critical step in informing consumers of safe operation of this appliance.

ATTACHING SAFETY-IN-OPERATION
WARNINGS

Your fireplace has been furnished with safety
instruction labels that are to be affixed to the
operation and control point of the fireplace. A safety
instruction label should be affixed to the wall switch
plate where the fireplace is turned on and off (See
Figure A) or wall thermostat (See Figure B) and if
used on the remote control handheld transmitter
(Figure C). The warnings should already have been
put in place when the fireplace initial set-up was
completed. If they are not affixed at these spots,
locate the multi-lingual adhesive labels provided with
these instructions and proceed as follows:

1. Locate the wall switch or wall thermostat that
controls the fireplace (verify the switch operates
the fireplace by turning it on and off). Clean the
wall switch plate or wall thermostat thoroughly
to remove any dust and oils. Affix the label to
the surface of the plate of the wall switch that
controls the fireplace (Figure A) or the wall
thermostat (Figure B). Choose the language
primarily spoken in the home.

2. If a remote control is used to control the fireplace,
locate the transmitter and clean it thoroughly
to remove any dust and oils. Affix the label to
the surface of handheld transmitter (Figure C).
Choose the language primarily spoken in the
home.

3. If you are unable to locate the labels, please call
Lennox Hearth Products or your nearest Lennox
Hearth Products dealer to receive additional
safety instruction labels free of charge.
