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 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 underneath
to prevent conduction of cold transferring to
the fireplace and into the room. It also helps to
sheetrock inside surfaces and tape for maximum
air tightness and caulk firestops.

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 locat­ing television sets and decorative plants.

NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.

Be aware that this is a heat producing ap­pliance. Objects placed above the unit are
exposed to elevated temperatures.

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.

**Note: See Page 9, Step 1 for clearance requirements to the nailing
flange located at each side of the unit and any screw heads adjacent
to it.

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 possible shelf surface, 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.

Wall Finishes / Surrounds / Mantels

Note: Combustible wall finish materials and/or surround materials must
not be allowed to en-croach the area defined by the appliance front
face (black sheet metal). Never allow combustible materials to be

positioned in front of or overlapping the appliance face (see Figure
55 on Page 34).

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.

Vertical installation clearances to combustible mantels vary accord­ing to the depth of the mantel. See Figure 9. 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.

DETAILED INSTALLATION STEPS
Step 1. FRAMING

Frame these appliances as illustrated in Figures
13 and 14 on Pages 10 and 11 (Figure 14

applies to corner framing installations only).

All framing details must allow for a minimum
clearance to combustible framing members as
shown in Table 5 on Page 8.

If the appliance is to be elevated above floor level,
a solid continuous platform must be constructed
below the appliance.

Headers may be in direct contact with the appli­ance top spacers when they are bent up vertically

maintaining the 3" clearance to the replace top,

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.

The fireplace should be secured to the side

framing members using the unit's nailing

flanges - one top and bottom on each side of
the fireplace front. See Figure 12. Use 8d nails
or their equivalent.

Step 2. ROUTING GAS LINE

Route a 1/2" (13 mm) gas line to the left side

of the appliance as shown in Figure 15. 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. (See
Step 6 on Page 26).

Figure 15 - Route Gas Line

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).

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 qualied 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

unqualied 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 Figure 40 on Pagec 26).

• 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 26).

• 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. INSTALL THE VENT SYSTEM

General Information

These instructions should be used as a
guideline 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/CSA-B149.1
in Canada.

Ensure clearances are in accordance with
local installation codes and the requirements
of the gas supplier.

Dégagement conforme aux codes d'installation
locaux et aux exigences du foumisseunde
gaz.

Use only approved venting components.
See Approved Vent Components on

Page 2.

These fireplaces must be vented directly
to the outside.

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
16, 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 16). Place the restrictor inside the ap-
pliance vent collar and press in place.

Note: The restrictor is included within the
firebox.

Vent Restrictor Installation

(Top Vent)

A vent restrictor may be needed when vertical­ly terminating the vent system above the roof
(when using the appliance top vent), install
vent restrictor in the top vent of the fireplace
outlet on all SLDVT series models. If needed,

install the restrictor orientated as shown,

either from inside or outside the unit,in 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.

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 36

and 37.

VERTICAL TERMINATION SYSTEMS (ROOF)

See Figure 17 on Page 13 and Figures 25 through
27 on Pages 16 and 17 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 speci-

ed 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 17)

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

35 - 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.

Figure 17

Effective Vent Length

Note: Convert inches into metric equivalent
measurement, as follows:

Millimeters (mm) = Inches x 25.4
Centimeters (cm) = Inches x 2.54

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 Pages 16 and 17 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

Vent Section Length Charts on Page 13 for an
aid in selecting length combinations. Elbows are

available in 90° and 45° congurations. Refer
to Figure 21 on Page 15 for the SV4.5E45 and
SV4.5E90 elbow dimensional specications.

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 tted 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 18).

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

Figure 19).

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.

Align the dimple (4 places) of the
upper vent section with the opening
of the locking incline channel on
the lower vent section or appliance
collar. Twist vent component
clockwise to engage and seal until

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 19). 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 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.

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 19.

D. Install firestop/spacer at ceiling - When us-

ing Secure Vent™, use SV4.5VF restop/spacer

at ceiling joists; when using Secure Flex™, use

SF4.5VF restop/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 (H3907) may be used
to obtain the required clearances indicated
here. See installation accessories Pages 35

and 36. The gap between the vent pipe and a
vertical firestop can be sealed with non-com­bustible caulking.

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 replace

vent outlet.

SUPERIOR DIRECT-VENT GAS FIREPLACES • MODELS SLDVT-30/35/40/45 • INSTALLATION INSTRUCTIONS

One method of support is by utilizing eld 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 20.

F. Change vent direction to horizontal/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.

Twist elbow sections in a clockwise direction
only so as to avoid the possibility of unlocking

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 ft. (1.52 m) along horizontal/inclined

vent runs using conventional plumber’s tape.

See Page 18, Figure 28. 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.

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 23). 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.

J. Install the storm collar - Install the storm
collar, supplied with the flashing, over the
vent/ashing joint (see Figure 23). 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.

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" in Figure 5 on Page 6.
The SV4.5CGV-1 Vertical Termination (Figure

24) can be installed 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
are seated at the end of the channels.

Figure 24

If the vent system extends more than 5 feet

(1.5m) above the roof ashing, 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.

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.

H. Frame roof opening - Identify location for
vent at the roof. Cut and/or frame opening per
Roof Framing Chart (Figure 22).

See Figure 28 on Page 18, and Figures 29
through 34 on Pages 19 through 22 and their

associated Horizontal Vent Table which illustrate
the various horizontal venting congurations

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 7 on Page 7 for location guidelines.

Example: If 20 feet total (H+H1)

horizontal vent run is needed, then
4 feet minimum of (V) vertical vent
will be required.

V

This table shows a 1(V) to 5(H)
ratio. For every 1 foot of (V)
vertical, you are allowed 5 feet
of (H+H1) horizontal run up to
a maximum total horizontal run
of 20 feet.

An elbow is acceptable as 1 foot
of vertical rise except where
an elbow is the only vertical
component in the system (see
Figure 31).

Secure Vent SV4.5 direct-vent system compo­nents are unitized concentric pipe components
featuring positive twist lock connection, (refer

to Figure 19 on Page 14). 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 vent lengths
so that a joint does not occur at the intersection

of ceiling or roof joists. Make allowances for

elbows as indicated in Figure 21.

B. Frame exterior wall opening -

Locate the center of the vent outlet on
the exterior wall according to the dimen­sions shown in Figure 13 on Page 10. Cut

and/or frame an opening, 10-1/2" x 12 1/8"
(267 mm x 308mm) inside dimensions, about

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 18 on Page 14).

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 (see Figure 19 on Page 14).

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 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 pre-

viously 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.

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 19 on Page 14.

F. Install firestop/spacer at ceiling ­When using Secure Vent, use SV4.5VF restop/

spacer at ceiling joists; when using Secure Flex,

use SF4.5VF restop/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 ­See Section E on Page 15.

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.

SV4.5L6/12/24/36/48

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
Figure 19 on Page 14).

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 28. 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.

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.

Use a carpenters level to measure from a
constant surface and adjust the support straps
as necessary.

J. Assemble vent run to exterior wall - If not
previously measured, locate the center of the
vent at the exterior wall. Prepare an opening as
described in Step B. Assemble the vent system
to point where the terminus of the last section is
located relative to the exterior surface to which
the termination is to be attached as shown in
Figure 30 and Table 8.

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
30, refer to Table 8 on Page 20. This Table lists

the additional venting components 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 termi­nation) to the vent section or telescoping vent
section), elbow or appliance collar as shown in
Figure 29 in the same manner as any SV4.5
vent component (refer to Step E).

L. Install Firestop/Spacer at exterior wall -

When using the 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 29, and nail into place.

(The Firestop/Spacer may also be installed over
the opening at the interior side of framing).

M. Install the Termination (SV4.5HT-2 or
SV4.5HTSS)

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 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 30.

time following the use of the fireplace.
To prevent contact with hot surfaces,
we recommend the use of a Termina-
tion Guard. See Page 37. This can be
purchased at your local dealer.

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.

VERTICAL OR HORIZONTAL VENTING USING
 KITS AND COMPONENTS

Secure Flex™ venting kits and components may

be used in any venting application in place of rigid

Secure Vent™ (SV4.5) direct-vent components.

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.

Using adaptor (SV4.5RF), 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 adaptor that
can be fitted to 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 adaptor over the previously installed
section or appliance collar, adjusting the radial
alignment until the four locking dimples of the
adaptor are aligned with the inlets of the four
incline channels of the last vent section or collar.
Push on the adaptor until it fully engages, then
twist the adaptor clockwise running the dimples
down and along the incline channels until they
seat at the end of the channels.

Attach the flexible vent to the adaptor as fol­lows (see also Figure 35):

A. Install the Inner Flex Pipe -

1. Install the small gear clamp loosely around

the inner flexible vent pipe, push it back out
of the way.

2. Apply a bead of Mill-Pac Black (700° F) high
temperature sealant - Catalog No. 10K81

to the inner adaptor collar, approximately
1/2 inch from the end.

3. Pull and extend the inner flexible vent pipe.

4. Slide the inner flex pipe over the adaptor col-

lar. Ensure the flexible vent pipe completely
engages the adaptor collar to a distance of

1 3/4 inches from the end, and that it is free

from damage or tears.

5. Slide the gear clamp down and tighten it
fully to secure the flexible vent to the adaptor

inner collar approximately 3/4 inch from the

end of the flex.

6. Install three screws, 120 degrees apart,
through the flexible vent pipe and into the
adaptor collar just below the gear clamp to
provide additional security to the connec­tion.

Note: Outer Pipe Is Pulled Away To
Show The Detail of The Inner Pipe

APPLY ONLY MIL-PAC BLACK
HIGH TEMPERATURE SEALANT
(Cat. No. 10K81) to the outside
surface of both collars of the
adaptor (be especially careful to
fill the grooves of the outer collar
to be covered by the flexible pipe)
and slide flexible pipe over inner
and outer adaptor collars.

B. Install the Outer Flex Pipe -

1. Install the large gear clamp loosely around

the outer flexible vent pipe, push it back out
of the way.

2. Apply a bead of Mill-Pac Black (700° F) high
temperature sealant - Catalog No. 10K81)

to the outer adaptor collar; to the grooves
of the collar which extend approximately 1
inch from the end and to the flat surface,

approximately 1-3/8 inches from the end.

3. Pull and extend outer flexible vent pipe.

4. Slide the outer flex pipe over the adaptor col-

lar. Ensure the flexible vent pipe completely
engages the adaptor collar to a distance of

1-3/8 inches from the end, and that it is free

from damage or tears.

5. Slide the gear clamp down and tighten it
fully to secure the flexible vent to the adaptor

outer collar approximately 3/4 inch from the

end of the flex.

6. Install three screws, 120 degrees apart,
through the flexible vent pipe and into the
adaptor collar just below the gear clamp to
provide additional security to the connec­tion.

C. Route Flex Vent -

Ensure that the flex vent is properly routed to
provide the required clearance. Do not allow the

exible vent to bend in a radius tighter than 5"
(127 mm). Refer to Figure 36. Space out the

internal flex vent spacers evenly - approximately
every 6 inches - and avoid kinking of inner pipe.

Support horizontal sections of ex with metal
straps at 2 foot (0.61 m) intervals.

E. Attach Flex Vent to Termination -
Secure Flex components can be purchased
separately and attached to bulk lengths of Se­cure Flex exible tubing cut to size at the job
site. Secure the flexible vent to the Secure Flex

terminations in the same manner (see Figure

35) as it was attached to the adaptor.

Note: Secure Flex vent must be attached to Se­cure Flex terminations only. DO NOT substitute
Secure Vent terminations or the Secure Vent
adaptor for Secure Flex components. The col­lars of Secure Flex terminations and adaptors
have a different diameter than that used with
the Secure Vent pipe. Additionally, Secure Flex
components have an extended length center
tube for use in attaching the flexible vent.

Step 6. CONNECTING GAS LINE

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

The flex-line method is acceptable in the U.S.A.
where local codes permit, however, Canadian
requirements vary depending on locality. Instal­lation must be in compliance with local codes.
These appliances are equipped with a gas flex
line for use in connecting the unit to the gas line.
See Figure 40 for flex line description. 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.

GAS CONNECTION

Figure 40

Note: The gas supply line must be installed in accordance with building codes by a quali­fied installer approved and/or licensed as required by the locality. In the Commonwealth
of Massachusetts, installation must be performed by a licensed plumber or gas fitter.

26

Access the valve compartment by removing the

lower control compartment panel (see Figure

41) by lifting and pulling the panel forward.

The panel is mounted on supporting tabs at
the extreme right and left hand sides. Engage
the tabs into the reliefs in the panel.

The millivolt and electronic control valve has a

3/8" (10 mm) NPT thread inlet port.

Secure all joints tightly using appropriate
tools and sealing compounds (ensure propane
resistant compounds are used in propane ap­plications). It is recommended to seal around
the gas line to prevent cold air leakage.

Gas line connection may be performed largely
outside of the confines of the control compart­ment and without having to enter the firebox
behind the glass. Proceed as follows:

Acquire the shut-off valve and gas lex line and
pull the assembly forward out of the compart­ment. Separate the shut-off valve from the gas
flex line. Determine the length of pipe needed

to route the gas line from the last tting (shown

in Figure 15 on Page 11) to a point within the
control compartment that will allow the shut­off valve to be easily attached by hand to the
gas flex line.

Using pipe-dressing materials appropriate for
the gas type, securely affix the shut-off valve
to this determined pipe length at a convenient
location outside of the appliance lower control
compartment.

Figure 41

Refer to Figure 42 and insert the last length
of gas pipe with its attached shut-off valve
into the lower control compartment, and pass
it through the gas line access hole on the left
side of the appliance outer wrapper.

Using appropriate materials for the gas type,
thread the last length of pipe into the end of the
gas vent run and tighten in place using a pipe
wrench external to the appliance between the
appliance outer wrapper and the framing.

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

WARNING

Never use an open flame to
check for leaks.

Turn on gas supply and test for gas leaks, us-

ing 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).

For piezo igniter location see Figure 41 on

Page 26 (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 41 on
Page 26) by pulling the panel forward.

When rst 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 ame (remove logs, if neces­sary, handling carefully).

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 ame should project 1" (25 mm) beyond the

hood at all three ports (see Figure 43). 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).

Electronic Appliance Checkout

To light the burner, turn ‘ON’ the unit mounted
On/Off switch or the optional remote wall switch.
Ensure the igniter lights the pilot. The pilot
flame should engulf the flame rod as shown
in Figure 44.

NOTE: Turn off all electricity to the appliance
before you install volcanic stone, embers and
logs.

1. Remove the front glass enclosure panel

(see Removing Glass Enclosure Panels on

Page 31).

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 7. VERIFYING APPLIANCE
OPERATION

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.

or broken.

AVERTISSEMENT

Ne pas utiliser l'appareil si le
panneau frontal en verre n'est
pas en place, est craqué ou
brisé.

Only doors certified with the appliance
shall be used.

Seules des portes certifiées pour cet
appareil doivent être utilisées.

CAUTION: DO NOT abuse glass door by
striking or slamming shut.

1. To access the glass door securing latches,

first open the lower control compartment
door (Figure 50) by lifting and pulling the
bottom panel forward.

2. Pull the latches forward and down to release

them from the door channel.

3. Pull the bottom of the door out a few inches

and grasp it on the right and left. Gently lift
to release the door from its channel above
the door. Pull the door forward.

4. Retrieve the glass door. Visually inspect the

gasket on the backside of the frame. Gasket
surface must be clean, free of irregularities
and seated firmly.

5. Inspect the gasket for defects. Insure it is

properly located. Make sure the bead is not

rolled up into the channel at the top of the
door, but remains flat against the top of the

glass (see Figure 50).

6. Position the door in front of the firebox

opening with the bottom of the door held
away from the fireplace (Figure 50). Hook
the top flange of the door frame over the top
of the firebox frame.

7. Let the bottom of the door frame swing

gently in towards the fireplace ensuring
that the gasket seats evenly as the door
frame draws shut. Fasten the two latches
located underneath the firebox floor to the

door's vee-ange. Close both the latches

securely.

8. Install the hood. Note the location of the three

clips inside the top air channel above the door.
The clips are equally spaced on the top surface
of the air channel opening. Use a screwdriver
to open the clips slightly if needed. Engage
the back edge of the eyebrow into the clips
to secure.

Step 10. 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 rst lit, the entire ame

may be blue and will gradually turn yellowish­orange 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

ame normalizes and the ames do not

appear sooty.

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

Burner Air Shutter Adjustment Procedure

WARNINGS

• 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.

1. Locate adjustment rod and adjust air shutter to the standard set-

ting as shown in Figure 54 (adjustment rod is located in the lower
control compartment).

Figure 52 - Burner Flame Appearance Model SLDVT-40

Note: Move the adjustment rod down to decrease air and up to

increase.

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 (see Figures51, 52 or 53 ). 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 flame appearance is
achieved.

• If ame stays lowered blue, adjust the air shutter, incrementally, to a

more closed position until the proper flame 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 satised that the burner ame appearance is normal, re-

install the lower control compartment door then proceed to finish the
installation.
