Step 2. ROUTING GAS LINE

Route a 1/2" (13 mm) gas line to the left side of the appliance as shown in Figure 15. Gas lines must be routed, constructed and made of materials that are in strict accordance with local codes and regulations. All appliances are factory-equipped with a ﬂexible gas line connector and 1/2 inch shutoff valve. (See Step 6 on Page 27).

3-1/8"

(79 mm)

5-5/8"

(143 mm)

Also see Figures 13 and 14.

Figure 15 - Route Gas Line

Proper Sizing of Gas Line

Properly size and route the gas supply line from the supply regulator to the area where the appliance is to be installed per requirements outlined in the National Fuel Gas Code, NFPA 54 - latest edition (USA) or CAN/CSA-B149.1

- latest edition (Canada).

Never use galvanized or plastic pipe. Refer to Table 6 for proper sizing of the gas supply line, if black iron pipe is being used. Gas lines must be routed, constructed and made of materials that are in strict accordance with local codes and regulations. We recommend that a 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.

code requirements (i.e. are below grade penetrations of the gas line allowed?, etc).

IMPORTANT: If propane is used, be aware that if tank size is too small (i.e. under 100-lbs, if

this is the only gas appliance in the dwelling.

Ref. NPFA 58), there may be loss of pressure,

resulting in insufﬁcient fuel delivery (which can result in sooting, severe delayed ignition

or other malfunctions). Any damage resulting

from an improper installation, such as this, is not covered under the limited warranty.

Step 3. PREPARING THE APPLIANCE VENT COLLAR

WARNING

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

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

Top Vent Installations - See Figure 16 Side Vent Installations - See Figure 17

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 16 for top vent installations and Figure 17 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.

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

restrictor in the top vent of the ﬁreplace outlet.

unit, in the inner ﬁreplace collar.

Restrictor

Use only approved venting components. See Approved Vent Components on Page 2.

These ﬁreplaces must be vented directly to the outside.

The vent system may not service multiple appliances, and must never be connected to a ﬂue serving a solid fuel burning appliance. The vent pipe is tested to be run inside an enclosed wall (such as a chase). There is no requirement for inspection openings in the enclosing wall at any of the joints in the vent pipe.

Installation of Vent Restrictor

A vent restrictor may be needed with this appliance. The restrictor is installed in the appliance top ﬂue outlet as shown in Figure 16, either before adding vent, from above, or after installation of vent from below, within the ﬁrebox. The restrictor is self securing through a positive friction ﬁt.

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

least 8 feet of vertical rise, then install the restrictor in the appliance collar before connecting any vent (Refer to Figure 19 ). Place the

restrictor inside the appliance vent collar and press in place.

Note: The restrictor is included within the ﬁrebox.

Select Venting System - Horizontal or Vertical

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

shown on Pages 37 and 38.

VERTICAL TERMINATION SYSTEMS (ROOF)

See Figure 19 and Figures 29 through 34 on Pages 18, 19 and 20 and their associated

Vertical Vent Tables which illustrate the various vertical venting conﬁgurations that are possible for use with these appliances. Secure Vent™ pipe applications are shown in these Figures; Secure Flex™ pipe may also be used. A Vertical Vent Table summarizes each system’s minimum and maximum vertical and horizontal length values that can be used to design and install the vent components in a variety of applications.

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

Figure 5 on Page 6).

Vertical (Straight) Installation

(Figure 19)

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 37 - Rigid Vent Sections).

Vertical (Offset) Installation

Analyze the vent routing and determine the quantities of vent sections and number of elbows required. Refer to Vertical Vent Figures and Tables on page 15 to select the type of vertical installation desired. Vent sections are available in net lengths of 4-1/2" (114 mm), 10-1/2" (267 mm), 22-1/2" (572 mm), 34-1/2" (876 mm) and 46-1/2" (1181 mm). Refer to the Effective Vent Length Chart on page 15 for an aid in selecting length combinations. Elbows are available in 90° and 45° conﬁgurations. Refer to Figure 24 for the SV4.5E45 and SV4.5E90 elbow dimensional speciﬁcations.

Where required, a telescopic vent section (SV4.5LA) may be used to provide the installer with an option in installing in tight and conﬁned spaces or where the vent run made up of ﬁxed length pieces develops a joint in a undesirable location, or will not build up to the required length. The SV4.5LA Telescopic Vent Section has an effective length of from 1-1/2" (38 mm) to 7-1/2" (191 mm). The SV4.5LA is ﬁtted with a locking inclined channel end (identical to a normal vent section component) and a plain end with 3 pilot holes. Slip the plain end over the locking channel end of a standard SV4.5 vent component the required distance and secure with three screws.

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

A. Frame ceiling opening - Use a plumb line

from the ceiling above the appliance to locate center of the vertical run. Cut and/or frame an opening, 10-1/2" x 10-1/2" (267mm x 267mm) inside dimensions, about this center mark (Figure 20 ).

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 21). Push the vent component against the collar until it fully engages, then twist the component clockwise, running the dimples down and along the incline channels until they seat at the end of the channels. The unitized design of the Secure Vent components will engage and seal both the inner and outer pipe without the need for sealant or screws. If desired a #6 x 1/2" screw may be used at the joint, but it is not required as the pipe will securely lock when twisted.

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

NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.

C. Attach vent components to each other

- Other vent sections may be added to the

previously installed section in accordance with the requirements of the vertical vent ﬁgures and tables. To add another vent component to a length of vent run, align the dimpled end over the inclined channel end of the previously installed section, adjusting the radial alignment until the four locking dimples are aligned with the inlets of the four incline channels of the previous section.

Push the vent component against the previous section until it fully engages, then twist the component clockwise running the dimples down and along the incline channels until they seat at the end of the channels.This seating position

is indicated by the alignment of the arrow and dimple as shown in Figure 22.

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 (96K94) may be used to obtain the required clearances indicated here. See installation accessories tables on pages 37 and 38.

run - At transition from or to a horizontal/inclined run, install the SV4.5E45 and SV4.5E90 elbows in the same manner as the straight vent sections. The elbows feature a twist section to allow them to be routed about the center axis of their initial collar section to align with the required direction of the next vent run element.

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

See Figure 24.

H. Frame roof opening - Identify location for vent at the roof. Cut and/or frame opening per Roof Framing Chart and Figure 25.

E. Support the vertical vent run sections -

Note - Proper venting support is very important. The weight of the vent must not be supported by the ﬁreplace in any degree.

Support the vertical portion of the venting system every 8 feet (2.4m) above the ﬁreplace vent outlet. One method of support is by utilizing ﬁeld provided support straps (conventional plumber's tape). Secure the plumber's tape to the framing members with nails or screws. Loop the tape around the vent, securing the ends of the tape to the framing. If desired, sheet metal screws #6 x 1/2" length may be used to secure the support straps to the vent pipe. See Figure 23.

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 26 ). Nail along perimeter to secure ﬂashing or adjust rooﬁng to overlap the ﬂashing edges at top and sides only and trim where necessary. Seal the top and both sides of the ﬂashing with waterproof caulking.

Figure 27

K. Install the vertical termination - The ﬁnal step involves installation of the SV4.5CGV-1 Vertical Termination. Extend the vent sections to the height as shown in the "Vertical vent termination section" on page 6. The SV4.5CGV-1 Vertical Termination (Figure 28 ) 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.

G. Continue installation of horizontal/inclined sections - Continue with the installation of the

straight vent sections in horizontal/inclined run as described in Step C. Install support straps every 5' (1.52 m) along horizontal/inclined vent runs using conventional plumber’s tape. It is

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

meter) of horizontal vent. Use a carpenter’s level to measure from a constant surface and adjust the support straps as necessary.

It is important to maintain the required clearances to combustibles: 1" (25 mm) at all sides for all vertical runs; and 3" (76 mm) at the top, 1" (25 mm) at sides, and 1" (25 mm) at the bottom for all horizontal/inclined runs.

Figure 26

J. Install the storm collar - Install the storm collar, supplied with the ﬂashing, over the vent/ﬂashing joint. See Figure 27. Loosen the storm collar screw. Slide collar down until it meets the top of the ﬂashing. Tighten the adjusting screw. Apply non-combustible caulking or mastic around the circumference of the joint to provide a water tight seal.

NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.

Figure 28

If the vent system extends more than 5' (1.5 m) above the roof ﬂashing, stabilizers may be necessary. Additional screws may be used at section joints for added stability. Guide wires may be attached to the joint for additional support on multiple joint conﬁgurations.

Page 18

VERTICAL VENT FIGURES/TABLES

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

Note: It is very important that the horizontal/in- clined run be maintained in a straight (no dips)

and recommended to be in a slightly elevated plane, in a direction away from the ﬁreplace of

1/4" rise per foot (20 mm per meter) which is ideal, though rise per foot run ratios that are smaller are acceptable all the way down to at or near level.

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

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

Note: An elbow is acceptable as 1 foot of

vertical rise, except where an elbow is the only vertical component in the system. (See Figure 38 on page 22 ).

HORIZONTAL (OUTSIDE WALL) TERMINATION SYSTEM

Figures 34, and Figures 37 to 42 on pages 22 to 24 and their associated Horizontal Vent

Table illustrate the various horizontal venting conﬁgurations that are possible for use with these appliances. Secure Vent pipe applications are shown in these ﬁgures; Secure Flex pipe may also be used. A Horizontal Vent Table summarizes each system’s minimum and maximum vertical and horizontal length values that can be used to design and install the vent components in a variety of applications.

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

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

are unitized concentric pipe components featuring positive twist lock connection, (refer to Figure 21 on page 16). All of the appliances covered in this document are ﬁtted with collars having locking inclined channels. The dimpled end of the vent components ﬁt over the appliance collar to create the positive twist lock connection.

A. Plan the vent run - Analyze the vent routing and determine the types and quantities of sections required 4-1/2" (114 mm), 10-1/2" (267 mm), 22-1/2" (572 mm), 34-1/2" (876 mm) and 46-1/2" (1181 mm) net section lengths are available. It is recommended that you plan the venting so that a joint does not occur in the ceiling or roof joists. Allow for elbows as indicated in Figure 24 on page 17.

Maintain a minimum 1" (25 mm) clearance to combustibles on the vertical sections. Clearances for the horizontal runs are; 3" (76 mm) on top, 1" (25 mm) on sides, and 1" (25 mm) at the bottom.

B. Frame exterior wall opening -

Locate the center of the vent outlet on the exterior wall according to the dimensions shown in Figures 13 & 14 on pages 11 & 12. Cut and/or frame an opening, 10-1/2" x 12-1/8" (267 mm x 308mm) inside dimensions, about this center.

C. Frame ceiling opening - If the vertical route is to penetrate a ceiling, use plumb line to locate the center above the appliance. Cut and/or frame an opening, 10-1/2" x 10-1/2" (267 mm x 267 mm) inside dimensions, about this center (refer to Figure 20 on page 16 ).

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 21 on page 16 ).

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.

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 22 on page 16.

F. Install ﬁrestop/spacer at ceiling -

When using Secure Vent, use SV4.5VF ﬁrestop/ spacer at ceiling joists; when using Secure Flex, use SF4.5VF ﬁrestop/spacer. If there is living space above the ceiling level, the ﬁrestop/ spacer must be installed on the bottom side of the ceiling. If attic space is above the ceiling, the ﬁrestop/ spacer must be installed on the top side of the joist. Route the vent sections through the framed opening and secure the ﬁrestop/spacer with 8d nails or other appropriate fasteners at each corner.

Remember to maintain 1" (25 mm) clearance to combustibles, framing members, and attic or ceiling insulation when running vertical chimney sections.

H. Change vent direction - At transition from or to a horizontal/inclined run, install the SV4.5E45 and SV4.5E90 elbows in the same manner as the straight vent sections. The elbows feature a twist section to allow them to be routed about the center axis of their initial collar section to align with the required direction of the next vent run element. Twist

elbow sections in a clockwise direction only so as to avoid the possiblity of unlocking any of the previously connected vent sections. See Figure 24 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 34, 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.

IMPORTANT: The vent termination is hot while in operation and for a period of time following the use of the ﬁreplace. To prevent contact with hot surfaces, we recommend the use of a Termina- tion Guard. See Page 38. This can be purchased at your local dealer.

Figure 36

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.

HORIZONTAL VENT FIGURES/TABLES

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

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

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

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

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

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

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 circumstances may separate sections of ﬂex pipe be joined together. Secure Flex kits may be added to the end of a vent run made up of rigid Secure Vent (SV4.5) vent sections provided that doing

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

Secure Flex kits come with an included adapter that can be ﬁtted to the appliance collar or the inclined channel end of the last Secure Vent (SV4.5) vent section in a rigid system in the exact same fashion as any other Secure Vent section. Align the dimpled end of the adapter over the previously installed section or appliance collar, adjusting the radial alignment until the 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 ﬂexible vent to the adapter as follows (see Figure 43):

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, approximately 1/2 inch 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 1-3/4 inches from the end, and that it is free from damage or tears.

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

Figure 43

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 1-3/8 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 44. Support horizontal sections of ﬂex with metal straps at 2 foot (0.61 m) intervals.

D. Install Firestop/Spacers at ceilings and walls - When Secure Flex penetrates a wall or ceiling, a ﬁrestop/spacer is required: use the SF4.5 VF ﬁrestop/spacer for ceilings and the SF4.5 HF ﬁrestop/spacer for walls.

NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.

See the appropriate sections and ﬁgures shown throughout the venting section for their installation requirments.

Figure 44

E. 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. Secure the ﬂexible vent to the Secure Flex terminations in the same manner (see Figure

43 ) 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 circumference 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.

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

WARNING

Never use an open ﬂame to check for leaks.

Step 7. CONNECTING GAS LINE

Make gas line connections. All codes require a

shut-off valve mounted in the supply line. Figure

50 illustrates two methods for connecting the

gas supply. The ﬂex-line method is acceptable

in the U.S., however, Canadian requirements

vary depending on locality. Installation must

be in compliance with local codes. A sediment

trap is recommended in the gas piping within

the home to prevent moisture and debris in the

line from damaging the valve.

These appliances are equipped with a gas ﬂex

line for use (where permitted) in connecting the

unit to the gas line. A gas ﬂex line is provided

to aid in attaching the direct vent appliance to

the gas supply. The gas ﬂex line can only be

used where local codes permit. Refer to Figure

51 for ﬂex line location. The ﬂex line is rated for

both natural and propane gas. A manual shut off

valve is also provided with the ﬂex line.

The gas control valve is located in the lower

control compartment.

To access the valve open the lower control

compartment door (see Figure 51 ) by pushing

in the right top corner of the door. (The door

is hinged at the bottom.) Remove the bottom

compartment door by sliding the hinge pin,

located at the door’s left side, to the right until

it disengages from the left corner post hole.

Pull the door diagonally to the left, away from

the ﬁreplace.

The lower control compartment door on the

side opposite the valve lifts on and off.

The millivolt control valve has a 3/8"

(10 mm) NPT thread inlet port. The electronic

control valve has a 1/2" (13 mm) NPT thread

inlet port and is ﬁtted with a 1/2" x 3/8" (13 mm x

10 mm) NPT ﬁtting.

Secure all joints tightly using appropriate

tools and sealing compounds (ensure propane

resistant compounds are used in propane

applications).

All codes require a shut-off valve mounted

in the supply line. The orientation of the

shut-off valve should face the front. Figure

50 illustrates two methods for connecting the

gas supply. A sediment Trap is recommended

to prevent moisture and debris in the gas line

for damaging the valve.

Note: Lighting Instructions are also found on

the literature tag tied to the gas piping next

to the gas valve. To access the tag, open the

lower control compartment door (Figure 51)

by pushing in simultaneously the left and right

top corners of the door. (The door is hinged at

the bottom). Remove the bottom compartment

door by sliding the hinge pin, located at the

door’s left side, to the right until it disengages

from the left corner post hole. Remove the

modesty panel. To remove the modesty panel,

slide the panel forward until it contacts the

cabinet bottom panel, then lift straight up and

tilt forward. Remove the modesty panel care-

fully, so that none of the wires become loose

or disconnected.

WARNING

• DO NOT attempt to install the 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.

•

The size and position of the log set was engineered to give the appliance a safe, reliable and attractive ﬂame pattern. Any attempt to use a different log set in the ﬁreplace will void the warranty and will result in incomplete combustion, sooting, and poor ﬂame quality.

• 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 electricity to the appliance before you install grate, volcanic stone, vermiculite, embers and logs.

•

This appliance is not designed to burn wood. Any attempt to do so could cause irreparable damage to the appliance and prove hazardous to your safety.

•

If logs are not installed according to the log installation instructions, ﬂame impingement and improper combustion could occur and result in soot and/or excessive production of carbon monoxide (CO), a colorless, odorless, toxic gas.

Step 11. BURNER ADJUSTMENTS

Flame Appearance and sooting

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

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

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

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