DETAILED INSTALLATION STEPS

TYPICAL INSTALLATION SEQUENCE

The typical sequence of installation follows,

however, each installation is unique resulting

in variations to those described.

See the Page numbers references in the follow-

ing steps for detailed procedures.

Step 1. (Page 10) Construct the appliance fram-

ing. Position the appliance within the framing and

secure with nailing fl anges.

Step 2. (Page 10) Route gas supply line to appli-

ance location.

Step 3. (Page 13) Install the vent system and

exterior termination.

Step 4.(Page 25) Field Wiring

a. Millivolt Appliances – Install the OFF/ON

burner control switch.

b. Electronic Appliances – Connect 120 VAC

electrical power to the appliance receptacle.

Step 5. (Page 26) Install blower kit (optional

equipment).

Step 6. ( Page 27) Make connection to gas

supply.

Step 7. (Page 28) Checkout appliance operation.

Step 8. (Page 28) Install embers, volcanic stone

and embers.

Step 9. (Page 29) Install glass enclosure pan-

els.

Step 10.(Page 29) Adjust burner primary air shutter

to achieve proper fl ame appearance.

Step 11 (Page 30) Install the decorative trim and

hoods.

Step 1. FRAMING

Frame these appliances as illustrated in Figures

13 & 14. All framing details must allow for a

minimum clearance to combustible framing

members as shown in Table 7 on Page 9.

1. Remove the shipping carton.

2. Remove the top louvered panel and locate the

pressure relief plates.

3. Lift the pressure relief plates and remove

the cardboard from beneath each plate (be

careful not to damage the white gasket). See

Figure 10.

Figure 12 - 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 B149 - latest edition

(Canada). Never use galvanized or plastic pipe.

Refer to Table 8 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 qualifi ed individual such as a plumber

or gas fi tter 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 unqualifi ed should attempt sizing

or installing gas piping.

Table 8

Notes:

• All appliances are factory-equipped with a

fl exible gas line connector and 1/2 inch shutoff

valve (see Figure 47 on Page 27).

• See Massachusetts Requirements on Page

3 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 27).

• 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 47). Appliances using

Propane should have a sediment trap at the

base of the tank.

• Check with local building offi 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 insuffi cient 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 2. ROUTING GAS LINE

Route a gas line along the inside of the right side

framing as shown in Figure 12. Gas lines must

be routed, constructed and made of materials

that are in strict accordance with local codes

and regulations.

If the appliance is to be elevated above fl oor

level, a solid continuous platform must be

constructed. Headers may be in direct contact

with the appliance top spacers but must not be

supported by them or notched to fi t around them.

All construction above the appliance must be

self supporting, DO NOT USE THE APPLIANCE

FOR STRUCTURAL SUPPORT.

Side Nailing Flanges

The fi replace should be secured to the fram-

ing at the side(s) of the appliance using the

factory-provided nailing fl anges. Install the 8

nailing fl anges as shown in Figure 11 using the

existing screws. Position the fi replace within

the framing. When required, the tabs may be

bent 90 degrees by hand or with the assistance

of a hammer. Use wood screws to secure the

nailing fl anges to the framing. See Table 7 on

Page 9 for clearances of framing members

to cabinet parts. The nailing fl ange itself can

directly contact framing.

Floor Nailing Tabs - Secure the fi replace to the

fl oor as shown in Figure 11.

Figure 11 - Nailing Flanges

Remove these screws and use them

when installing nailing fl anges.

Nailing Flanges

Turn nailing tabs down and secure to fl oor with 8d

nails or other appropriate fasteners on both sides of

appliance which do not have viewing glass panels.

Step 3. INSTALL THE VENT SYSTEM

These instructions should be used as a guideline and do not supersede

local codes in any way. Install vent according to local codes, these instruc-

tions, 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.

• Use only approved venting components. See Approved Vent Compo-

nents, Page 2.

• These fi replaces must be vented directly to the outside.

The vent system must NOT service multiple appliances, and must never

be connected to a fl ue serving a solid fuel burning appliance. The vent

pipe is tested to be run inside an enclosure (such as a chase). There is

no requirement for inspection openings in the enclosure at any of the

joints in the vent pipe.

REMOVE VENT SEAL CAP

(From the vent that will be used only)

Top Vent - See Figure 15 and Side Vent - See Figure 16

Preparing the Appliance Vent Collar

Each of the appliances' two vent collars are sealed with a seal cap which

must be removed from the vent collar being used. Refer to Figure 15

for top vent installations and Figure 16 for side vent installations and

the following steps to prepare the appropriate collar for use.

From the vent collar being used, remove the two screws securing the

vent seal cap. Twist the cap counterclockwise. Pull it away from the

appliance and discard, along with the piece of insulation.

VENTING SYSTEM - HORIZONTAL OR VERTICAL

With the appliance secured in framing, determine vent routing and identify

the exterior termination location. The following sections describe vertical

(roof) and horizontal (exterior wall) vent applications. Refer to the section

relating to your installation. A list of approved venting components is

shown on Pages 31 and 32.

VERTICAL TERMINATION SYSTEMS (ROOF)

See Figure 18 and Figures 27 to 31 and their

associated Vertical Vent Tables illustrate the

vertical venting confi gurations that are allowed

to be used with these appliances. Secure Vent

pipe applications are shown in these fi gures;

Secure Flex pipe may also be used. See Page

24. 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. In the USA, the minimum

vent height above the roof and/or adjacent walls

is specifi ed in ANSI Z223.1 (latest edition); in

Canada, by the current CAN-1 B149 installation

code. It is also specifi ed in major building codes.

Always consult your local codes for specifi c

requirements. A general guide to follow is the

Gas Vent Rule (refer to Figure 4 on Page 7).

Vertical (Straight) Installation

Determine the number of straight vent sec-

tions 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 Table 10 and Page 31 - Item

3). Plan the vent lengths so that a section joint

does not occur within the space defi ned by

ceiling joists or roof rafters. Refer to the Vent

Section Length Chart.

Another method, where the vent is not adjacent

to a wall, is illustrated in Figure 22. Here,

support straps (96K93) and support plates

(96K92) can be used to support the weight

of the vent.

D. Install fi restop / spacer at ceiling - When

using Secure Vent, use SV4.5VF fi restop / spacer

at ceiling joists; when using Secure Flex, use

SF4.5VF fi restop / spacer. If there is living space

above the ceiling level, the fi restop / spacer must

be installed on the bottom side of the ceiling.

If attic space is above the ceiling, the fi restop /

spacer must be installed on the top side of the

joist. Route the vent sections through the framed

opening and secure the fi restop / 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 ver-

tical chimney sections. Attic insulation shield

(96K94) may be used to obtain the required

clearances indicated here. See installation

accessories o n Pages 31 and 32.

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 fi replace in any degree.

Support the vertical portion of the venting

system every 8 feet (2.4 m) above the fi replace

vent outlet. One method of support is by utiliz-

ing fi 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. See Figure 21.

Vertical (offset) Installation

Analyze the vent routing and determine the

number of vent sections and elbows required.

Refer to Vertical Vent Figures and Tables on

Pages 17 and 18 to select the type of vertical

installation desired. Refer to the Vent Section

Length Charts on Page 14 for an aid in se-

lecting vent length combinations. Elbows are

available in 45° and 90° confi gurations. Refer

to Figure 23 for the SV4.5E45 and SV4.5E90

elbow dimensional specifi cations.

Where required, a Telescopic Vent Section

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

with an option in installing in tight and confi ned

spaces or where the vent run made up of fi xed

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 fi 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 ele-

ments 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 19).

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 20). Push the vent component

against the collar until it fully engages, then

twist the component clockwise, running the

dimples down and along the incline channels

until they seat at the end of the channels. The

unitized design of the Secure Vent components

will engage and seal both the inner and outer

pipe without the need for sealant or screws.

If desired a #6 x 1/2" screw may be used at the

joint, but it 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 20.

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 20). All of the appliances covered in this

document are fi tted with collars having locking

inclined channels. The dimpled end of the vent

components fi t over the appliance collar to cre-

ate the positive twist lock connection.

If the vent system extends more than 5 feet

(1.5 m) above the roof fl 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 sup-

port on multiple joint confi gurations.

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 feet (1.52 m) along horizontal / inclined

vent runs using conventional plumber’s tape.

See Page 19, Figure 32. 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 fi replace 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.

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 23.

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 24.

K. Install the vertical termination - The fi nal

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" (Page 7, Figure 4). The

SV4.5CGV-1 Vertical Termination (Figure 26)

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.

I. Install the roof fl ashing - Extend the vent

sections through the roof structure. Install the

roof fl ashing over the vent section and position

such that the vent column rises vertically (use

carpenters level - see Figure 25). Nail along

perimeter to secure fl ashing or adjust roofi ng

to overlap the fl ashing edges at top and sides

only and trim where necessary. Seal the top

and both sides of the fl ashing with waterproof

caulking.

J. Install the storm collar - Install the storm

collar, supplied with the fl ashing, over the vent /

fl ashing joint. See Figure 25. Loosen the storm

collar screw. Slide collar down until it meets

the top of the fl ashing. Tighten the adjusting

screw. Apply non-combustible caulking or

mastic around the circumference of the joint

to provide a water tight seal.

See Figure 32, and Figures 35 to 40 and

their associated Horizontal Vent Table which

illustrates the horizontal venting confi gura-

tions that are allowed to be used with these

appliances. Secure Vent pipe applications are

shown in these fi gures; Secure Flex pipe may

also be used (see Page 24). 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 specifi c areas. Refer to

Figure 6 on Page 8 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 20 on Page 15). All of the appli-

ances covered in this document are fi tted with

collars having locking inclined channels. The

dimpled end of the vent components fi t 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 section joint does not occur

within the space defi ned by ceiling joists, roof

rafters or wall studs. Make allowances for elbows

as indicated in Figure 23 on Page 16.

by the alignment of the arrow and dimple as

shown in Figure 20 on Page 15.

F. Install fi restop / spacer at ceiling -

When using Secure Vent, use SV4.5VF fi restop

/ spacer at ceiling joists; when using Secure

Flex, use SF4.5VF fi restop / spacer. If there is

living space above the ceiling level, the fi restop/

spacer must be installed on the bottom side of

the ceiling. If attic space is above the ceiling,

the fi restop/ spacer must be installed on the

top side of the joist. Route the vent sections

through the framed opening and secure the

fi restop / spacer with 8d nails or other ap-

propriate fasteners at each corner.

Remember to maintain 1" (25 mm) clearance

to combustibles, framing members, and attic

or ceiling insulation when running vertical

chimney sections. Attic insulation shield

(96K94) may be used to obtain the required

clearances indicated here. See installation

accessories Tables on Pages 31 and 32.

G. Support the vertical run sections -

See Step 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 direc-

tion 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 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 32. 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 fi replace 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.

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 exte-

rior wall according to the dimensions shown in

Figures 13 & 14 on Pages 11 & 12.

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 19 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

20 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.

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.

IMPORTANT

The vent termination is hot while

in operation and for a period of

time following the use of the fi re-

place. To prevent contact with hot

surfaces, we recommend the use

of a Termination Guard. See Items

12 and 13 on Page 31. This can be

purchased at your local dealer.

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.

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 end 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

SV4.5HT-2 termination is to be attached, see

Figure 34. If the end of the last section is not

within this distance, use the telescopic vent sec-

tion SV4.5LA, as the last vent section. For wall

thicknesses greater than that shown in Figure

34, refer to Table 11 on Page 21. 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 (SV4.5RCH - provided with the termi-

nation) to the vent section or telescoping vent

section), elbow or appliance collar as shown

in Figures 33 & 34 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

33, and nail into place. The Firestop / Spacer

may also be installed over the opening at the

interior side of the framing.

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

Install the square termination - For the last

step , from outside the exterior wall, slide the

collars of the termination onto the adapter 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 34.

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 roofl ines may create a heavy fl ow 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.

VERTICAL OR HORIZONTAL VENTING USING

SECURE FLEX 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 fl exible venting. Secure Flex kits may

not be modifi ed; also, under no circumstances

may separate sections of fl ex pipe be joined

together.

Using adapter (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 adapter that

can be fi tted 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 adapter over

the previously installed section or appliance

collar, adjusting the radial alignment until the

four locking dimples of the adapter are aligned

with the inlets of the four incline channels 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 fl exible vent to the adapter as fol-

lows (see also Figure 41):

A. Install the Inner Flex Pipe -

1. Install the small gear clamp loosely around

the inner fl exible 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, approximately

1/2 inch from the end.

3. Pull and extend the inner fl exible vent pipe.

4. Slide the inner fl ex pipe over the adapter col-

lar. Ensure the fl exible vent pipe completely

engages the adapter 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 fl exible vent to the adapter

inner collar approximately 3/4 inch from the

end of the fl ex.

6. Install three screws 120 degrees apart through

the fl exible 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 fl exible 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 fl at surface,

approximately 1-3/8 inches from the end.

3. Pull and extend outer fl exible vent pipe.

4. Slide the outer fl ex pipe over the adapter col-

lar. Ensure the fl exible vent pipe completely

engages the adapter 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 fl exible vent to the adapter

outer collar approximately 3/4 inch from the

end of the fl ex.

6. Install three screws 120 degrees apart

through the fl exible vent pipe and into the

adapter collar just below the gear clamp to

provide additional security to the connec-

tion.

C. Route Flex Vent -

Ensure that the fl ex vent is properly routed to

provide the required clearance. Do not allow the

fl exible vent to bend in a radius tighter than 5"

(127 mm). Refer to Figure 42. Space out the

internal fl ex vent spacers evenly - approximately

every 6 inches - and avoid kinking of inner pipe.

Support horizontal sections of fl 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 Se-

cure Flex fl exible tubing cut to size at the job

site. Secure the fl exible vent to the Secure Flex

terminations in the same manner (see Figure

41) as it was attached to the adapter.

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 components. The collars of Secure

Flex terminations and adapters 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 fl exible vent.

TEST ALL CONNECTIONS FOR GAS LEAKS

(FACTORY AND FIELD):

Turn on gas supply and test for gas leaks using a

gas leak test solution (also referred to as bubble

leak solution). Note: Using a soapy water solution

(50% dish soap, 50% water) is an effective leak

test solution but it is not recommended, because

the soap residue that is left on the pipes/fi ttings

can result in corrosion over time.

WARNING

Never use an open fl ame to check for leaks.

Turn on gas supply and test for gas leaks using

a gas leak test solution.

A. Light the appliance (refer to the lighting

instructions label in control compartment

or homeowner's manual).

B. Brush all joints and connections with the gas

leak test solution to check for leaks. If bubbles

are formed, or gas odor is detected, turn the

gas control knob (off/pilot/on) to the “OFF”

position. Either tighten or refasten the leaking

connection, then retest as described above.

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

sure to rinse off the leak testing solution,

D. Turn on burner then observe the individual

tongues of fl ame on the burner. Make sure

all ports are open and producing fl ame evenly

across the burner. If any ports are blocked, or

partially blocked, clean out the ports.

Note:The gas supply line must be installed in

accordance with building codes by a qualifi ed

installer approved and/or licensed as requed by

the locality. In the Commonwealth of Massachu-

setts, installation must be performed by a licensed

plumber or gas fi tter.

Step 6. CONNECTING GAS LINE

Make gas line connections. All codes require a

shut-off valve mounted in the supply line. Figure

47 illustrates two methods for connecting the

as supply. The fl ex-line method is acceptable

in the U.S., however, Canadian requirements

vary depending on locality. Installation must

be in compliance with local codes.

These appliances are equipped with a gas fl ex

line for use (where permitted) in connecting

the appliance to the gas line. A gas fl ex line

is provided to aid in attaching the direct vent

appliance to the gas supply. The gas fl ex line

can only be used where local codes permit.

See Figure 47 for fl ex line description. The fl ex

line is rated for both natural gas and propane

gas. A manual shut off valve is also provided

with the fl ex line.

The incoming gas line should be piped into

the valve compartment and connected (see

Figures 47 & 48). The millivolt control

valve has a 3/8" (10 mm) NPT thread

inlet port. The electronic control valve

has a 1/2" (13 mm) NPT thread inlet port

and is fi tted with a 1/2" x 3/8" (13 mm x

10 mm) NPT fi tting.

Secure all joints tightly using appropriate

tools and sealing compounds (ensure propane

resistant compounds are used in propane

applications).

Optional: Seal around the gas line to prevent

cold air leakage.

Step 8. INSTALLING LOG SET, VOLCANIC

STONE AND GLOWING EMBERS

WARNING

Logs get very hot and will remain

hot up to one hour after gas supply

is turned off. Handle only when

logs are cool. Turn off all elec-

tricity to the appliance before you

install grate and logs.

WARNING

This appliance is not designed to

burn wood. Any attempt to do so

could cause irreparable damage

to the appliance and prove haz-

ardous to your safety.

WARNING

DO NOT attempt to install logs

until the appliance installation

has been completed, the gas line

connected and tested for leaks

and the initial burner operation

has been checked out.

Figure 50

Electronic Appliance Checkout

To light the burner, turn ‘ON’ the OFF/ON switch

(located in the control compartment). Ensure the

igniter lights the pilot. The pilot fl ame should

engulf the fl ame rod as shown in Figure 51.

Observe the individual tongues of fl ame on

the burner. Make sure all ports are open and

producing fl ame evenly across the burner. If

any ports are blocked, or partially blocked,

clean out the ports.

Step 7. CHECK APPLIANCE OPERATION

With the gas line installed, run initial system

checkout before closing up the front of the

appliance. Follow the pilot lighting instructions

provided in the Homeowner's Care and Opera-

tion Instructions. For piezo igniter location see

Figure 48 (millivolt appliances only).

Note: The (pull-out) Lighting instructions label

can be found in the control compartment

(see Figure 48).

When fi 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 lightings

of the appliance will not require such purging.

Inspect the pilot fl ame.

Millivolt Appliance Checkout

The pilot fl ame should be steady, not lifting

or fl oating. 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" min (tip) of the

quick drop out thermocouple should be engulfed

in the pilot fl ame. The fl ame should project 1"

(25 mm) beyond the hood at all three ports

(Figure 50).

To light the burner; rotate the gas valve control knob

counterclockwise to the “ON” position then turn

“ON” the OFF/ON switch (installed at Step 4).

Observe the individual tongues of fl ame on

the burner. Make sure all ports are open and

producing fl ame evenly across the burner. If

any ports are blocked, or partially blocked,

clean out the ports.

The log set foam package is located in the fi rebox

and the bags of decorative volcanic stone and

the glowing embers (rockwool) are located in

the control compartment. Refer to the following

information and Figures 52 and 54 for detailed

placement instructions.

Install the decorative volcanic stone and

glowing embers (rockwool):

Spread the decorative volcanic stone on the

simulated brick fl oor of the fi rebox around

the burners to simulate ashes. Maintain a 1/2

inch (13 mm) gap between the bottom of the

horizontal grate section and the top of the pile

of decorative volcanic stone. Place a few dime-

sized pieces of the glowing ember material

on the pan burner in front of the burned out

area on both sides of the log set. The glowing

embers may touch one another, but should not

overlap each other.

Install the unitized log set:

a. The bottom of the log set is notched to ac-

commodate the pilot.

b. Place the log set so that the four inner notches

on the underside of the log set fi t over the

four risers located on the burner ends. See

Figure 52. This procedure is accomplished

primarily by feel, as the log set masks the

burner risers as it is being installed.

c. As a fi nal check for correct log set placement,

check that the four outer notches on the

underside of the log set fi t over the burner

tines as indicated in Figure 52.

WARNING

If logs are not installed according

to the log installation instruc-

tions, fl ame impingement and

improper combustion could

occur and result in soot and/or

excessive production of carbon

monoxide (CO), a colorless,

odorless, toxic gas.

(see Figure 55)

1. Remove the top louver assembly by lifting it

up and pulling it out.

2. Remove the control compartment access

door (see removal instructions on Page 27

- Removing Control Compartment Door).

3. Locate the two (2) latches at the top of the

control compartment. To disengage the two

latches from the bottom vee-fl ange of the

glass enclosure panel, reach for the handles

located towards the back of the latches and

pull the handles down toward the front of

the appliance.

4. Swing the bottom of the door out and raise

it slightly to lift the top fl ange of the door

frame away from the appliance.

Installing Glass Enclosure Panels

(see Figure 55)

1. Visually inspect the gasket on the backside of the

the bottom of the panel with the latches and

close the latches to secure the panel.

4. Reinstall top louver assembly and control

compartment door see installation instructions

on Page 27, Reinstalling Control Compart-

ment Door).

Step 10. BURNER ADJUSTMENTS

Flame Appearance and sooting

Proper fl ame appearance is a fl ame which is

blue at the base and becomes yellowish-orange

in the body of the fl ame. When the appliance

is fi rst lit, the entire fl ame may be blue and will

gradually turn yellowish-orange during the fi rst

15 minutes of operation. If after a short period

the fl ame stays lowered blue, or if the fl ame is

orange with evidence of sooting (black tip), the

air shutter opening may need to be adjusted.

If the air shutter openings closed too far, sooting

may develop. Sooting is indicated by black puffs

developing at the tips of very long orange fl ames.

Sooting results in black deposits forming on the

logs, appliance inside surfaces and on exterior

surfaces adjacent to the vent termination. Soot-

ing is caused by incomplete combustion in the

fl ames and lack of combustion air entering the

air shutter opening. To achieve a warm yellow-

ish-orange fl ame 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, fi rst check

the log set positioning to ensure that the

fl ames 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 fl ames that appear

blue and transparent. These weak, blue and

transparent fl ames are termed anemic.

• Propane models may exhibit fl 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 fl ame normal-

izes and the fl 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

1. Locate adjustment rod and adjust air shutter

to the standard setting as shown in Figure

56 (adjustment rod is located in the lower

control area).

Note: Rotating the adjustment rod coun-

terclockwise decreases air and clockwise

increases air.

2. Light appliance (follow lighting procedure

on lighting label in control compartment or

see homeowners manual).

3. Allow the burner to operate for at least 15

minutes while observing the fl ame continu-

ously to ensure that the proper fl ame appear-

ance has been achieved (see Figure 52). If

the following conditions are present, adjust

accordingly.

• If flame appears weak or sooty, adjust

the air shutter, incrementally, to a more

open position until the proper fl ame

appearance is achieved.

• If fl ame stays lowered blue, adjust the

air shutter, incrementally, to a more

closed position until the proper fl ame

appearance is achieved.

4. Leave the control knob (off/pilot/on) in the

ON position and the burner OFF/ON switch

OFF (& remote switches, if applicable).

5. When satisfi ed that the burner fl ame ap-

pearance is normal, close the lower control

compartment door then proceed to fi nish

the installation.
