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.

Be aware that this is a heat producing ap-

pliance. Objects placed above the unit are

exposed to elevated temperatures.

Do not insulate the space between the ap-

pliance and the area above it (see Figure 8

on Page 8).

The minimum height from the base of the appli-

ance to the underside of combustible materials

used to construct a utility shelf in this fashion

is shown in Figure 8 on Page 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.

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

other raised 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.

MANUFACTURED HOME

This appliance may be installed in an aftermar-

ket permanently located, manufactured home

and must be installed in accordance with the

manufacturer's instructions and the Manufac-

tured Home Construction and Safety Standard,

Appliance And Vent Clearances

The appliance is approved with zero clearance to com-

bustible 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).

See Note

in Figure 8.

** 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.

*** Note: To ensure proper ﬁt of the facade (required - sold

separately). The appliance base will need to be elevated

3/4" minimum above the ﬂoor to allow for the proper

ﬁt of the facade (i.e. use 3/4" board as platform).

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 appli-

ance 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 the table in Figure 8.

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 al-

low combustible materials to be positioned in front of or

overlapping the appliance front face.

Non-combustible materials, such as surrounds and other

appliance trim, may be installed on the appliance front face

with these exceptions: they must not cover any portion

of the glass or the air gaps above the glass door.

Vertical installation clearances to combustible mantels

vary according to the depth of the mantel. Mantels

constructed of non-combustible materials may be

installed above the appliance opening as outlined in

Figure 9.

NOTE: We recommend the use of high temperature

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

mantel.

NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.

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 but must not be sup-

ported 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 fram-

ing members using the unit's nailing ﬂanges

each side of the ﬁreplace front (see Figure 11).

Use 8d nails or their equivalent.

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).

Notes:

• All appliances are factory-equipped with

a ﬂexible gas line connector and 1/2 inch

shutoff valve (see Figure 39 on Page 24).

• 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 24).

• Apipejointcompoundratedforgasshouldbe

used on the threaded joints. Ensure propane

resistant compounds are used in propane

applications. Be very careful that the pipe

compound does not get inside the pipe.

• Itisrecommendedtoinstallasedimenttrap

in the supply line as close as possible to the

appliance (see Figure 39). 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 pen-

etrations 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.

Never use galvanized or plastic pipe. Refer

to Table 6 for proper sizing of the gas sup-

ply line, if black iron pipe is being used. Gas

lines must be routed, constructed and made

of materials that are in strict accordance with

local codes and regulations. We recommend

that a qualiﬁed individual such as a plumber or

gas ﬁtter be hired to correctly size and route

the gas supply line to the appliance. Installing

a gas supply line from the fuel supply to the

appliance involves numerous considerations of

materials, protection, sizing, locations, controls,

pressure, sediment, and more. Certainly no one

unfamiliar and unqualiﬁed should attempt sizing

or installing gas piping.

Step 2. ROUTING GAS LINE

Route a 1/2" (13 mm) gas line along the inside

of the left side framing 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 con-

nector and 1/2 inch shutoff valve. (See Step 6

on Page 24).

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 vent 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.

The vent system may not service multiple ap-

pliances, 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.

Select Venting System - Horizontal or Verti-

cal

With the appliance secured in framing, de-

termine 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 in the tables

on Page 32.

VERTICAL TERMINATION SYSTEMS (ROOF)

See Figures 16, and 24 through 26 on

Pages 14 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 ap-

plications 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-

ﬁed in ANSI Z223.1-(latest edition) (In Canada,

the current CAN/CSA-B149 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 16)

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

32 - 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.

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 18). Push the vent component against

the collar until it fully engages, then twist the

component clockwise, running the dimples

down and along the incline channels until they

seat at the end of the channels.

The unitized design of the Secure Vent com-

ponents will engage and seal both the inner

and outer pipe without the need for sealant or

screws. If desired a #6 x 1/2" screw may be

used at the joint, but it is not required as the

pipe will securely lock when twisted.

C. Attach vent components to each other - Other

vent sections may be added to the previously

installed section in accordance with the require-

ments 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 lock-

ing dimples are aligned with the inlets of the four

incline channels of the previous section.

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 18).

All of the appliances covered in this document

are ﬁtted with collars having locking inclined

channels. The dimpled end of the vent compo-

nents ﬁt over the appliance collar to create the

positive twist lock connection.

Align the dimple (four places) of the

upper vent section with the opening

of the locking incline channel on the

lower vent section or appliance col-

lar. Twist vent component clockwise

to engage and seal until arrow and

dimple align.

is indicated by the alignment of the arrow and

dimple as shown in Figure 18.

D. Install ﬁrestop/spacer at ceiling - When

using Secure Vent, use SV4.5VF ﬁrestop/spacer

at ceiling joists; 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 may be used to obtain the

required clearances indicated here (order

H3907, SV4.5ARSA, Attic insulation shield

with adjustable height from 12"-22"). See

installation accessories table on Page 32.

The gap between the vent pipe and a vertical

ﬁrestop can be sealed with non-combustible

caulking.

E. Support the vertical vent run sections -

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.

Vertical (Offset) Installation

Analyze the vent routing and determine the

quantities of vent sections and number of el-

bows required. Refer to Vertical Vent Figures

and Tables on Page 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 Chart on Page 14 for an

aid in selecting length combinations. Elbows are

available in 90° and 45° conﬁgurations. Refer

to Figure 20 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) clear-

ance to combustible materials for all

vertical vent components. Clearances for

all horizontal vent components 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" (267 mm x 267

mm) inside dimensions, about this center mark

(Figure 17).

NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.

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

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 clear-

ances to combustibles: 1" (25 mm) at all sides

for all vertical runs; and 3" (76 mm) at the top,

1" (25 mm) at sides, and 1" (25 mm) at the

bottom for all horizontal/inclined runs.

H. Frame roof opening - Identify location for

vent at the roof. Cut and/or frame opening per

Roof Framing Chart and Figure 21.

I. Install the roof ﬂashing - Extend the vent

sections through the roof structure. Install the

roof ﬂashing over the vent section and posi-

tion such that the vent column rises vertically

(use carpenters level) (Figure 22). 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/ﬂashing joint. See Figure 22. Loosen

the storm collar screw. Slide collar down until

it meets the top of the ﬂashing. Tighten the

adjusting screw. Apply non-combustible caulk-

ing or mastic around the circumference of the

joint to provide a water tight seal.

Figure 22

Storm

Flashing

Figure 23

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.

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 ter-

mination section" on Page 6. The SV4.5CGV-1

Vertical Termination (Figure 23) 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.

One method of support is by utilizing ﬁeld pro-

vided 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. See Figure 19.

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

any of the previously connected vent sections

(see Figure 20).

NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.

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. 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 18 on Page 15).

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 27, 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 clear-

ances to combustibles: 1" (25 mm) at all sides

for all vertical runs; and 3" (76 mm) at the top,

1" (25 mm) at sides, and 1" (25 mm) at the

bottom for all horizontal/inclined runs.

Use a carpenter’s level to measure from a

constant surface and adjust the support straps

as necessary.

HORIZONTAL (OUTSIDE WALL) TERMINATION

SYSTEM

See Figures 27, and Figures 30 to 33 on Pages

18, 20 and 21 and their associated Horizontal

Vent Table which illustrate the various horizontal

venting conﬁgurations that are possible for use

with these appliances. Secure Vent™ pipe ap-

plications 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.

Secure Vent SV4.5 direct-vent system compo-

nents are unitized concentric pipe components

featuring positive twist lock connection, (refer

to Figure 18 on Page 15). All of the appli-

ances 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 recom-

mended 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 20 on Page 16.

Maintain a minimum 1" (25 mm) clearance to

combustibles on the vertical sections. Clear-

ances 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 dimen-

sions shown in Figure 12 on Page 10. Cut

and/or frame an opening, 10-1/2" x 12-1/8"

(267 mm x 308 mm) 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 17 on Page 15).

D. Attach vent components to appliance - To

attach a vent component to the appliance collar,

align the dimpled end over the collar, adjust-

ing the radial alignment until the four locking

dimples are aligned with the inlets of the four

incline channels on the collar (refer to Figure

18 on Page 15).

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

previously installed section in accordance with

the requirements of the vent tables. To add

another vent component to a length of vent

run, align the dimpled end of the component

over the inclined channel end of the previously

installed section, adjusting the radial alignment

until the four locking dimples are aligned with

the inlets of the four incline channels of the

previous section.

Push the vent component against the previous

section until it fully engages, then twist the

component clockwise running the dimples

down and along the incline channels until they

seat at the end of the channels. This seating

position is indicated by the alignment of the

arrow and dimple as shown in Figure 18 on

Page 15.

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.

Termination

Horizontal terminations have been designed to perform in a wide range of weather condi-

tions. Our terminations meet or exceed industry standards.

When selecting the locations of your horizontal terminations, do not place the termina-

tion where water from eaves and adjoining rooﬂines may create a heavy ﬂow of cascad-

ing 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.

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 29 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

29, 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 termi-

nation) to the vent section or telescoping vent

section), elbow or appliance collar as shown

in Figure 28 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 28, and nail into place.

(The Firestop/Spacer may also be installed over the

opening at the interior side of the framing).

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 adap-

tor (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 29.

IMPORTANT: The vent termination is hot

while in operation and for a period of time

following the use of the ﬁreplace. Young

children should be carefully supervised

when they are in the same area as a hot

termination. To prevent contact with hot

surfaces, we recommend the use of a

Termination Guard. See Page 32. This

can be purchased at your local dealer.

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.

of 20 feet except for installations where an elbow is the only vertical

vent section in the system (see Figure 30).
