Note: For combustible material refer to

Figure 48 on page 26.

These appliances are designed to operate on

natural or propane gas only.

This installation manual will help you obtain a

safe, efficient, dependable installation for your

appliance and vent system.

The Installation must conform to local codes

or, in the absence of local codes, with the

National Fuel Gas Code, ANSI Z223.1/NFPA

, or the

Natural Gas and Propane Installa-

tion Code, CSA B149.1

. The appliance, when

installed, must be electrically grounded in

accordance with local codes or, in the ab-

sence of local codes, with the

National Elec-

trical Code, ANSI/NFPA 70

, or the

Canadian

Electrical Code, CSA C22.1

These appliances are listed by Omni-Test

Laboratories for installation in bedrooms and

mobile homes.

WARNING: 1) FIRE HAZARD: DO NOT

PLACE ANY COMBUSTIBLE MATERIAL

OVER THE FIREPLACE OPENING. 2) DOOR

FRONT ACCESSIBILITY: ANY NON-COM-

BUSTIBLE FINISHING MATERIAL AREAS

THAT PROTRUDE MORE THAN 1" FROM

THE FACING SHOULD MAINTAIN A 9"

CLEARANCE TO THE FIREPLACE OPEN-

ING. SEE FIGURE 7, PAGE 6 FOR DETAILS.

NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.

Test gage connections are provided on the

front of the gas control valve (identified IN

for the inlet and OUT for the manifold side).

Do not use these appliances if any part has

been under water. Immediately call a quali-

fied, professional service technician to inspect

the appliance and to replace any parts of the

control system and any gas control which

have been under water.

Ne pas se servir de cet appareil s'il a été plongé

dans l'eau, complètement ou en partie. Appeler

un technicien qualifié pour inspecter l'appareil et

remplacer toute partie du système de contrôle et

toute commande qui ont été plongés dans l'eau.

These appliances feature a comfort control

valve which allows remote control of tem-

perature, fan and flame appearance. These

appliances also use a spark ignitor (piezo)

that allows the appliance's pilot gas to be lit

without the use of matches. This system

provides continued service in the event of a

power outage.

These appliances must not be connected to a

chimney or flue serving a separate solid fuel

burning appliance.

Carbon Monoxide Poisoning: Early signs of

carbon monoxide poisoning are similar to

the flu with headaches, dizziness and/or

nausea. If you have these signs, obtain

fresh air immediately. Turn off the gas sup-

ply to the appliance and have it serviced by

a qualified professional, as it may not be

operating correctly.

LOCATION

In selecting the location, the aesthetic and func-

tional use of the appliance are primary concerns.

However, vent system routing to the exterior and

access to the fuel supply are also important.

Consideration should be given to traffic ways,

furniture, draperies, etc., due to elevated surface

temperatures (

see Figure 2

Typical Locations

The location should also be free of electrical,

plumbing or other heating/air conditioning duct-

ing. 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.

Do not insulate the space between the appli-

ance and the area above it. See

Figure 3

. 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 3

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 materi-

als. However, if installed on combustible ma-

terials, such as carpeting, vinyl tile, etc., a

metal or wood barrier covering the entire bot-

tom surface must be used.

APPLIANCE AND VENT CLEARANCES

These appliances are approved with zero clear-

ance from spacers to combustible materials on

all sides (as detailed in

Table 2

), with the

following exception: When the unit is installed

with one side flush with a perpendictular side

wall, the wall perpendicular to the opposite side

of the appliance front face must not extend

more than five inches beyond the front edge of

the unit. In addition, when the unit is recessed,

the side walls surrounding the unit must not

extend more than five inches beyond the front

edge of the unit. Refer to

Step 3. INSTALL THE VENT SYSTEM

General Information

These instructions should be used as a guide-

line 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/CGA-B149.1 and -

B149.2 in Canada.

These fireplaces are designed, tested

and listed for operation and installation

with, and only with, Secure Vent™ Direct

Vent System Components, Secure Flex™

Flexible Vent Components manufactured

by Security Chimneys International and

Z-FLEX™ Model GA Venting Systems listed

to UL1777 and ULCS635 manufactured by

Flexmaster Canada Limited.

These approved vent system components

are labeled for identification.

DO NOT

use any other manufacturer's vent

components with these appliances.

Some local jurisdictions may require the gap

between the outer wall of the vent system

and the firestop penetration opening to be

sealed. This is not a requirement of the

listing of this product, however this gap may

be sealed using aluminized tape or similar

non-combustible material.

The vent system may not service multiple appli-

ances, and must never be connected to a flue

serving a solid fuel burning appliance. The vent

pipe is tested to be run inside an enclosing 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 Vertical

With the appliance secured in framing, deter-

mine vent routing and identify the exterior

termination location. The following sections

describe vertical (roof) and horizontal (exte-

rior wall) vent applications. Refer to the sec-

tion relating to your installation. A list of

approved venting components is shown in

the two tables on page 27.

VERTICAL TERMINATION SYSTEMS (ROOF)

Figure 15, and Figures 25 through 27 on

pages 12 and 15

and their associated

Vertical Vent Tables illustrate the various verti-

cal 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-

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

the current CAN-1 B149 installation code) by

major building codes. Always consult your

local codes for specific requirements. A gen-

eral guide to follow is the Gas Vent Rule (refer

Figure 11

on page 9).

Massachusetts And New York City, NY

above grade and be directly in line with the

horizontal termination. The sign must read, in

print size no less than one-half (1/2) inch in

size, GAS VENT DIRECTLY BELOW. KEEP

CLEAR OF ALL OBSTRUCTIONS.

These fireplaces must be vented directly

to the outside.

Step 2. ROUTING GAS LINE

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

of the right side framing as shown in

Figure 13

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 flex-

ible gas line connector and 1/2" inch shutoff

valve. (See step 5 on page 21).

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 17

All of the appliances covered in this document are

fitted with collars having locking inclined chan-

nels. The dimpled end of the vent components fit

over the appliance collar to create the positive

twist lock connection.

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 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.

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 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 previ-

ously 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.

component clockwise running the dimples down

and along the incline channels until they seat at

the end of the channels. This seating position

is indicated by the alignment of the arrow and

dimple as shown in

Figure 18.

D. Install firestop/spacer at ceiling - When using

Secure Vent, use SV4.5VF firestop/spacer at ceil-

ing 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 appro-

priate 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.

E. Support the vertical vent run sections -

Support the vertical portion of the venting sys-

tem every 8 feet (2.4m) above the fireplace vent

outlet using field provided support straps (con-

ventional 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.

Where required, a telescopic vent section

(SV4.5LA) may be used to provide the in-

staller with an option in installing in tight and

confined spaces or where the vent run made

up of fixed length pieces develops a joint in a

undesirable location, or will not build up to the

required length. The SV4.5LA Telescopic Vent

Section has an effective length of from 1-1/2"

(38 mm) to 7-1/2" (191 mm). The SV4.5LA is

fitted with a locking inclined channel end (iden-

tical 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 16

14 NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.

Figure 21

Figure 22

Figure 24

Figure 23

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 termina-

tion section" on page 9. The SV4.5CGV-1 Ver-

tical Termination (

Figure 24

) installs in the exact

same fashion as any other Secure Vent section.

Align the termination over the end of the previ-

ously installed section, adjusting the radial align-

ment until the 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.

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 22

). Nail along perim-

eter to secure flashing or adjust roofing to over-

lap the flashing edges at top and sides only and

trim where necessary. Seal the top and both

sides of the flashing with waterproof caulking.

If the vent system extends more than 5' (1.5 m)

above the roof flashing, stabilizers may be nec-

essary. 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.

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

J. Install the storm collar - Install the storm

collar, supplied with the flashing, over the

vent/flashing 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 caulk-

ing or mastic around the circumference of the

joint to provide a water tight seal.

Storm

Figure 20

F. Change vent direction to horizontal/in-

clined run - At transition from or to a horizon-

tal/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

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 (Se-

cure Flex) firestop/spacer must be used any-

time 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 com-

bustible 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.

TYPICAL HORIZONTAL VENT INSTALLATION

Figure 28

Secure Vent SV4.5 direct vent system compo-

nents are unitized concentric pipe components

featuring positive twist lock connection, (

refer to

Figure 17

on page 13). 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. Plan the

vent lengths so that a joint does not occur at the

intersection of ceiling or roof joists. Make al-

lowances for elbows as indicated in

Figure 20

on page 13

. Maintain a minimum 1" (25 mm)

clearance to combustibles on the vertical sec-

tions. 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

Figure 4

on page 5. Cut and/or frame an

opening, 10-1/2" x 12-1/8" (267 mm x 267

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 16

on page 12 ).

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 17

on page 13).

G. Support the vertical run sections -

See Section E on page 13.

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 compo-

nents will engage and seal both the inner and outer

pipe elements with the same procedure. Sealant

and securing screws are not required.

E. Attach vent components to each other -

Other vent sections may be added to the previ-

ously 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 lock-

ing 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 13.

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.

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. Use a carpenter’s

level to measure from a constant surface and

adjust the support straps as necessary.

Both of these horizontal vent systems terminate

through an outside wall. Building Codes limit or

prohibit terminating in specific areas. Refer to

Figure 14

on page 10 for location guidelines.

Figure 28, and Figures 31 to 33 on pages 16,

18 and 19

and their associated Horizontal Vent

Table illustrate the various horizontal venting

configurations that are possible for use with

these appliances. Secure Vent pipe applica-

tions are shown in these figures; Secure Flex

pipe may also be used. A Horizontal Vent Table

summarizes each system’s minimum and maxi-

mum vertical and horizontal length values that

can be used to design and install the vent

components in a variety of applications.

HORIZONTAL (OUTSIDE WALL)

TERMINATION SYSTEM

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 re-

quired direction of the next vent run element.

Twist elbow sections in a clockwise direc-

tion only so as to avoid the possiblity of

unlocking any of the previously connected

vent sections. See

Figure 20

Remember to maintain 1" (25 mm) clear-

ance to combustibles, framing members,

and attic or ceiling insulation when running

vertical chimney sections.

IMPORTANT: The vent termination is hot

while in operation and for a period of time

following use of the fireplace. To prevent

contact with hot surfaces, we recommend

the use of a Termination Guard. 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.

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

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 within 5 in. (127 mm) to 9-1/4 in. (235 mm)

inboard of the exterior surface to which the

termination is to be attached, see

Figure 30

. 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

, refer to

Table 3 on page 18

. 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 tele-

scoping vent section), elbow or appliance col-

lar 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 square termination, install

SV4.5HF (Secure Vent), SF4.5HF (Secure Flex)

Firestop/Spacer over the opening at the exte-

rior 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 the framing).

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 termina-

tion with the arrow pointed upwards. Secure

the termination to the exterior wall.

Orient the housing of the termination with the

VERTICAL OR HORIZONTAL VENTING USING

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 circum-

stances 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 con-

siderations 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 appli-

ance collar, adjusting the radial alignment until

the four locking dimples of the adapter are

aligned with the inlets of the four incline chan-

nels of the last vent section or collar. Push on

the adapter until it fully engages, then twist the

adapter 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 adapter as

follows (

also see

Figure 34

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 adapter collar, approxi-

mately 1/2 inches from the end.

3. Pull and extend the inner flexible vent pipe.

4. Slide the inner flex pipe over the adapter

collar. Ensure the flexible vent pipe completely

engages the adapter collar to a distance of 1³⁄₄

inch 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 adapter

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 adapter collar

just below the gear clamp to provide additional

security to the connection.

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 adapter collar; to the grooves of the

collar which extend approximately 1 inch from

the end and to the flat surface, approximately

1³⁄₈ inches from the end.

3. Pull and extend the outer flexible vent pipe.

4. Slide the outer flex pipe over the adapter

collar. Ensure the flexible vent pipe completely

engages the adapter collar to a distance of 1³⁄₄

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 adapter

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

adapter 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 flexible vent to bend in a radius tighter than

5" (127 mm). Refer to

Figure 35

. Support

horizontal sections of flex with metal straps at

2 foot (0.61 m) intervals.

Note:

Secure Flex

vent must be attached to

Secure Flex

terminations only. DO NOT

substitute

Secure Vent

terminations or the

Secure Vent

adapter for

Secure Flex

compo-

nents. The collars of

Secure Flex

termina-

tions and adapters have a different circum-

ference 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.

D. Attach Flex Vent to Termination -

Secure Flex components can be purchased

separately and attached to bulk lengths of

Secure Flex flexible tubing cut to size at the

job site. When using this method connect the

flex vent only to Flex Vent terminations, not

Secure Vent terminations. Secure the flexible

vent to the Secure Flex terminations in the

same manner (see

Figure 34)

as it was at-

tached to the adapter.
