NEW YORK CITY, NY AND MASSACHUSETTS REQUIREMENTS

These appliances are approved for installation in the following USA locations listed in the following:

Massachusetts -

Installation of these fireplaces are approved for installation in the US state of Massachusetts if the following additional requirements are met -

•Installation and repair must be done by a plumber or gas fitter licensed in the Commonwealth of Massachusetts.

•The flexible gas line connector used shall not exceed 36 inches (92 centimeters) in length.

•The individual manual shut-off must be a T-handle type valve.

NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.

Massachusetts Horizontal Vent Requirements

In the Commonwealth of Massachusetts, horizontal terminations installed less than seven (7) feet above the finished grade must comply with the following additional requirements:

•A hard wired carbon monoxide detector with an alarm and battery back-up must be installed on the floor level where the gas fireplace is installed. The carbon monoxide detector must comply with NFPA 720, be ANSI/UL 2034 listed and be IAS certified.

•A metal or plastic identification plate must be permanently mounted to the exterior of the building at a minimum height of eight (8) feet 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.”

New York City, New York

These fireplaces are approved for installation in New York City in the US state of New York.

Cold Climate Insulation

For cold climate installations, seal all cracks around the appliance with noncombustible material and wherever cold air could enter the room. It is especially important to insulate outside chase cavity between studs and under floor on which the appliance rests, if floor is above ground level.

Gas line holes and other openings should be caulked or stuffed with unfaced fiberglass insulation. If the fireplace is being installed on a cement slab, in cold climates, a sheet of plywood or other raised platform can be placed underneath to prevent conducting cold up into the room. It also helps to sheetrock inside surfaces and tape for maximum air tightness and caulk firestops.

Location

In selecting the location, the aesthetic and functional use of the appliance are primary concerns. However, vent system routing to the exterior and access to the fuel supply are also important. Consideration should be given to traffic ways, furniture, draperies, etc., due to elevated surface temperatures (see Figure 4 ). The location should also be free of electrical, plumbing or other heating/air conditioning ducting.

These direct vent appliances are uniquely suited for installations requiring a utility shelf positioned directly above the fireplace. Utility shelves like these are commonly used for locating television sets and decorative plants. Be aware that this is a heat producing appliance. Objects placed above the unit are exposed to elevated temperatures.

NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.

To provide for the lowest possible shelf surface use the alternate rear vent outlet with attached venting routed in a way to minimize obstructions to the use of the space above the appliance. Do not insulate the space between the appliance and the area above it. See Figure 9. 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 9.

The appliance should be mounted on a fully supported base extending the full width and depth of the unit. The appliance may be located on or near conventional construction materials. However, if installed on combustible materials, such as carpeting, vinyl tile, etc., a metal or wood barrier covering the entire bottom surface must be used.

Step 3. Install the Vent System

General Information

Useonlyapprovedventingcomponents. 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 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.

WARNING

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

Installation of Vent Restrictor

Aventrestrictormaybeneededwiththisappliance, installventrestrictor(provided)intheappliancetop flue outlet as shown in Figure 16 (SSDVT-3328 ) or rear flue outlet as shown in Figure 17 (SSDVR3328 ). It is held in place by friction, only.

Vent Restrictor Installation

(Top Vent)

A vent restrictor may be needed when vertically terminating the vent system above the roof (when using the appliance top vent), install vent restrictor in the top vent of the fireplace outlet on SSDV-3328 series models. If needed, install the restrictor orientated as shown, either from inside or outside the unit,in the inner fireplace collar.

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 is shown on Pages 32 through 34.

Vertical Termination Systems (Roof)

Figure 21 (Page 15), and Figures 26 to 30 (Pages 17 and 18) and their associated Vertical Vent Tables 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-1 B149 installation code) by major building codes. Always consult your local codes for specific requirements. A general guide to follow is the Gas Vent Rule (refer to

Figure 5 on Page 7).

Vertical (Straight) Installation

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 Table 11 and Page 32 - Item 3). Plan the vent lengths so that a joint does not occur at the intersection of ceiling or roof joists. Refer to the Vent Section Length Chart.

Vertical (Offset) Installation

Analyze the vent routing and determine the quantitiesofventsectionsandnumberofelbows required. Refer to Vertical Vent Figures and Tables on Pages 17 and 18 to select the type of vertical installation desired. Vent sections are available in net lengths of 4-1/2" (114 mm), 10-1/2" (267 mm), 22-1/2" (572 mm), 34-1/2 " (876 mm) and 46-1/2" (1181 mm). Refer to the

Vent Section Length Chart on Page 14 for an aid in selecting length combinations. Elbows are available in 90° and 45° configurations. Refer to Figure 22 on Page 16 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 combustiblematerialsforallverticalelements. 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 19 ).

B. Attach vent components to appliance - Secure Vent SV4.5 direct vent system components are unitized concentric pipe components featuring positive twist lock connections (see

Figure 20).

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.

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

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

C. Attach vent components to each other - Other vent sections may be added to the previously installed section in accordance with the requirements of the vertical vent Figures and Tables.

NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.

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 componentclockwiserunningthedimplesdown 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.

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, Pages 32 through 34.

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 firplace 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. Refer to Figure 21.

F. Change vent direction to horizontal/inclined 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 22.

G. Continue installation of horizontal/inclined sections - Continue with the installation of the straight vent sections in horizontal/inclined run as described in Step C. Install support straps every 5 ft. (1.52 m) along horizontal/inclined vent runs using conventional plumber’s tape.

See Page 19, Figure 31. It is very important that the horizontal/inclined run be maintained in a straight (no dips) and recommended to be ina slightlyelevatedplane, inadirection 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 clearances to combustibles: 1" (25 mm) at all sides for all vertical runs; and 3" (76 mm) at the top, 1" (25 mm) at sides, and 1" (25 mm) at the bottom for all horizontal/inclined runs.

H. Frame roof opening - Identify location for vent at the roof. Cut and/or frame opening per Roof Framing Chart and 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 24 ). Nail along perimeter to secure flashing or adjust roofing to overlap the flashing edges at top and sides only and trim where necessary. Seal the top and both sides of the flashing with waterproof caulking.

J.Install the storm collar - Install the storm collar, supplied with the flashing, over the vent/flashing joint. See Figure 24. 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 NOT TO SCALE.

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 7. The SV4.5CGV-1 Vertical Termination (Figure 25) can be installed in the exact same fashion as any other Secure Vent section. Align the termination over the end of the previously installed section, adjusting the radial alignment until the four locking dimples of the termination are aligned with the inlets of the four incline channels of the last vent section. Push the termination down until it fully engages, then twist the termination clockwise running the dimples down and along the incline channels until they are seated at the end of the channels.

Figure 25

If the vent system extends more than 5 feet (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.

VERTICAL VENT FIGURES/TABLES

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

WARNING

Under no circumstances, may separate sections of concentric flexible vent pipe be joined together.

Notes:

•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.

•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.

•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.

•AN ELBOW IS ACCEPTABLE AS 1 FOOT OF VERTICAL RISE EXCEPT WHERE AN ELBOW IS THE ONLY VERTICAL COMPONENT IN THE SYSTEM (See Figure 35).

J. Assemble vent run to exterior wall - If not previously measured, locate the center of the vent at the exterior wall. Prepare an opening as described in Step B. Assemble the vent system to point where the terminus of the last section is located relative to the exterior surface to which the termination is to be attached (see Figures 32 & 33 and Table 12 on Page 21.

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 33 on Page 20 and Table 12 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 (adapter - SV4.5RCH - provided with the termination) to the vent section or telescoping vent section, elbow or appliance collar as shown in Figures 32 & 33 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 32, and nail into place.

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

M. Install the Square Termination (SV4.5HT-2 or SF4.5HT-2)

Install the square termination - For the last step , from outside the exterior wall, slide the collars of the termination onto the adapter (the outer inside the outer and the inner outside the inner) until the termination seats against the exterior wall surface to which it will be attached. Orient the housing of the termination with the arrow pointed upwards. Secure the termination to the exterior wall. The horizontal termination must not be recessed into the exterior wall or siding by more than the 1-1/4" (32 mm) as shown in Figure 33.

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 Termination Guard. See Items 12 and 13 on Page 32. This can be purchased at your local dealer.

		To help minimize water infiltration it is
		recommended that the Firestop/Spacer
		(SV4.5HF) be installed on the exterior
		side of the wall.

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.

Notes:

•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.

•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.

•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.

•The tables show a 1(V) to 5(H) ratio up to a maximum horizontal run of 20 feet except for installations where an elbow is the only vertical vent section in the system (see Figure 35).

•AN ELBOW IS ACCEPTABLE AS 1 FOOT OF VERTICAL RISE EXCEPT WHERE AN ELBOW IS THE ONLY VERTICAL COMPONENT IN THE SYSTEM. See Figure 35.

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 flexible venting. Secure Flex kits may not be modified; also, under no circumstances may separate sections of flex 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 fitted to the inclined channel end of the last Secure Vent (SV4.5) vent section in a rigid system in the exact same fashion as any other

Secure Vent section.

Align the dimpled end of the 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 also Figure 41):

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. Installthreescrews120degreesapartthrough theflexibleventpipeandintotheadaptercollar justbelowthegearclamptoprovideadditional security to the connection.

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

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

B.Install the Outer Flex Pipe -

1.Install the large gear clamp loosely around the outer flexible vent pipe, push it back out of the way.

2.Apply a bead of Mill-Pac Black (700° F) high temperature sealant - Catalog No. 10K81) to the outer adapter collar; to the grooves of the collar which extend approximately 1 inch from the end and to the flat surface, approximately 1 3/4 inches from the end.

3.Pull and extend 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 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 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 42. Space out the internal flex vent spacers evenly - approximately every 6 inches - and avoid kinking of inner pipe. Support horizontal sections of flex with metal straps at 2 foot (0.61 m) intervals.

NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.

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. See the appropriate sectionsandFiguresshownthroughouttheventing section for their installation requirements.

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 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 adapterforSecureFlexcomponents.Thecollars ofSecureFlexterminationsandadaptershavea differentdiameterthanthatusedwiththeSecure Ventpipe. Additionally,SecureFlexcomponents have an extended length center tube for use in attaching the flexible vent.

*A Sediment Trap is recommended to prevent moisture and debris in gas line from damaging the valve.

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

Figure 46 - GAS CONNECTION

Step 6. Connecting Gas Line

Make gas line connections. All codes require a shut-off valve mounted in the supply line. Figure 46 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.

These appliances are equipped with a gas flex line for use (where permitted) in connecting the appliance 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. See Figure 46 for flex line description. The flex line is rated for both natural gas and propane gas. A manual shut off valve is also provided with the flex line.

The incoming gas line should be piped into the valve compartment and connected (see Figures 46 & 47). 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).

Optional: Seal around the gas line to prevent cold air leakage.

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

WARNING

Never use an open flame to check for leaks.

Turn on gas supply and test for gas leaks using a gas leak test solution (also referred to as bubble leaksolution). Note:Usingasoapywatersolution (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/fittings can result in corrosion over time.

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 flame on the burner. Make sure all ports are open and producing flame evenly across the burner. If any ports are blocked, or partially blocked, clean out the ports.

Step 7. Checking 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 Operation 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 47).

When first 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 flame.

SIT and Honeywell Millivolt Appliance Checkout

The pilot flame should be steady, not lifting or floating. Flame should be blue in color with traces of orange at the outer edge.

NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.

The top 3/8" (10 mm) at the pilot generator (thermopile) and the top 1/8" min (tip) of the quickdropoutthermocoupleshouldbeengulfed in the pilot flame. The flame should project 1" (25 mm) beyond the hood at all three ports (Figure 49 - SIT, Figure 50 - Honeywell).

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 flame on the burner. Make sure all ports are open and producing flame evenly across the burner. If any ports are blocked, or partially blocked, clean out the ports.

INSTALL Logs, VOLCANIC STONE and

GLOWING EMBERS

Carefully position the ceramic fiber logs and twigs over the burner according to the following steps, while referring to Figure 52.

1.Set the rear log on the raised log support brackets at the rear of the firebox, fitting the slots in the log over the brackets.

2.Position the front log with the pins for the two side twigs in the up position, and the two vertical burner tabs recessed into the two notches at the rear of the log. Check for recessing of brackets into log notches (by touch) to verify correct log placement.

3.Insert the alignment hole of the left twig over the front log's left pin. Rotate the left twig until it just touches the edge of the ember bracket.

4.Insert the alignment hole of the right twig over the front log's right pin. Rotate the right twig until it almost touches the front panel glass.

Note: Proper twig placement is critical in the gaps between the flame peaks and should be positioned so that at no time they impinge the flames.

Glowing Ember/Volcanic Stone Placement

Remove the replacement rockwool (Glowing Embers) from the packaging and tear into quarter size pieces (see Figure 53 ).

Spread rockwool (quarter-sized pieces) on and along the length of the burner screen. Do not use more than is necessary. To many quartersized pieces on the front burner section will cause poor combustion.

When properly positioned, the rockwool will unevenly cover approximately 85% of the burner screen, with no appreciable gaps or openings.

To install Decorative Volcanic Stone, mound up a portion of the volcanic stone in front of the burner in a pattern to suite individual taste.

Figure 52 - Log Set (Shown With Optional Log Rack)

NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.

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 electricity to the appliance before you install grate and logs.

WARNING

DONOTattempttoinstallthelogs until the appliance installation has been completed, the gas line connected and tested for leaks and the initial burner operation has been checked out.

WARNING

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.

WARNING

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

Step 10. Burner Adjustments

Flame Appearance and sooting

Proper flame appearance is a flame which is blue at the base and becomes yellowish-orange in the body of the flame. When the appliance is first lit, the entire flame may be blue and will gradually turn yellowish-orange during the first 15 minutes of operation. If after a short period the flame stays lowered 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 openings 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 yellow- ish-orange flame with an orange body that does not soot, the shutter opening must be adjusted between these two extremes.

NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.

Air Shutter Adjustment Guidelines

•If there is smoke or soot present, first check the log set positioning to ensure that the flames are not impinging on any of the logs. If the log set is properly positioned and a sooting condition still exists, then the air shutter opening should be increased.

•Themoreoffsetsintheventsystem,thelarger the air shutter opening will need to be.

•An appliance operated with the air shutter opened too far, may have flames that appear blue and transparent. These weak, blue and transparent flames are termed anemic.

•Propane models may exhibit flames 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 flame normalizes and the flames do not appear sooty.

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

Air Shutter Adjustment Guidelines:

Amount of	Flame	Air Shutter
Primary Air	Color	Adjustment
If air shutter is	Flame will	Air shutter

WARNING

Airshutteradjustmentshouldonly beperformedbyaqualifiedprofessional service technician.

WARNING

Ensure front glass panels are in place and sealed during adjustment.

CAUTION

Carbon will be produced if the air shutter is closed too much. Any damage due to carboning resulting from improperly setting the air shutter is not covered under the warranty.

Burner Air Shutter Adjustment Procedure

CAUTION

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 compartment).

Note: Move the adjustment rod down to decreases air and up to increases.

2.Light appliance (follow lighting procedure on lighting label in control compartment or see Care and Operations manual).

3.Allow the burner to operate for at least 15 minutes while observing the flame continuously to ensure that the proper flame appearance has been achieved (see Figure 55). If the following conditions are present, adjust accordingly.

•If flame appears weak or sooty, adjust air shutter, incrementally, to a more open position until the proper flame appearance is achieved.

•Ifflamestaysloweredblue,adjust airshutter,incrementally,toamore closed position until the proper flame appearance is achieved.

4.Leave the control knob (off/pilot/on) in the ON position and the burner OFF/ON switch OFF (& remote switches, if applicable).
