IMPORTANT: PLEASE READ AND

UNDERSTAND THESE RULES TO

FOLLOW FOR SAFETY.

1. Before starting your fireplace installation, read these installation instructions carefully to be sure you understand them completely and in entirety. Failure to follow them could cause a fireplace malfunction resulting in serious injury and/or property damage.

2. Always check your local building codes. The installation must comply with all local, regional, state and national codes and regulations.

3. These fireplaces must be installed with

Security Chimneys FTF10 [10" (254mm) inside diameter] Chimney System only. These systems are intended for use in any application where a traditional masonry type fireplace would apply. The chimney system must always vent to the outside of the building.

4. To ensure a safe fireplace system and to prevent the build-up of soot and creosote, inspect and clean the fireplace and chimney prior to use and periodically during the heating season.

5. Use solid fuel only. DO NOT use artificial wax based logs, chemical chimney cleaners or flame colorants in your fireplace.

6. DO NOT use charcoal or coal under any circumstances.

7. NEVER use gasoline, gasoline-type lantern fuel, kerosene, charcoal lighter fluid, or similar liquids to start or “freshen up” a fire in this fireplace. Keep any flammable liquids at safe distance from the fireplace.

8. NEVER leave children unattended when there is a fire burning in the fireplace.

9. Always keep flue damper open when heat is present in the fireplace.

10. Before servicing, allow the fireplace to cool. Always shut off any electricity or gas to the fireplace while working on it. This will prevent any possible electrical shock or burns.

11. This fireplace is not intended to heat an entire home or be used as a primary heat source. It is designed to ensure homeowner comfort by providing supplemental heat to the room.

12. Always ensure that an adequate supply of replacement combustion air from the outside of the house is accessible to the fire to support normal combustion. Fireplaces consume large volumes of air during the normal combustion process. In the event the home is tightly sealed with modern energy efficient features, the optional combustion air kit may not provide all the air required to support combustion.

The manufacturer is not responsible for any smoking or related problems that may result from the lack of adequate combustion air. It is the responsibility of the builder/contractor to ensure that adequate combustion air has been provided for the fireplace.

13. DO NOT use a fireplace insert or any other products not specified herein by the manufacturer for use with this fireplace. All gas log sets must be operated with the damper clamped open, including unlisted “vent free” log sets.

Listed “vent-free” log sets may be operated with the damper closed.

14. "Smoke free” operation is not warranteed nor are we responsible for inadequate system draft caused by mechanical systems, general construction conditions, inadequate chimney heights, adverse wind conditions and/or unusual environmental factors or conditions beyond our control.

15. Never, under any circumstances, install a fireplace, chimney component or any accessories, that has visible or suspected physical damage as a result of handling or transportation. These items should be inspected by your distributor or qualified factory representative to ensure safe condition. When in doubt, consult your distributor.

16. For additional safety considerations and complete operating instructions, refer to the

Care and Operation Manual provided with the fireplace.

LOCATION OF FIREPLACE

Carefully select the proper location for heat circulation, aesthetics, chimney obstructions and clearance to side wall(s). With proper preplanning, a slight adjustment of a few inches can save considerable time and expense later during construction and assembly.

Hearth

Chase Enclosure

A chase is a vertical box-like structure constructed to surround the fireplace and chimney.

Refer to

Figure 2 for a typical chase configuration. As with all chimney installations, avoid overhead obstructions such as trees, power lines, etc. A chase should be constructed and insulated just like any outside wall. In a cold climate, we recommend the base of the chase should also be insulated between the solid continuous floor beneath the fireplace and the chase bottom. Chase insulation in a cold climate installation is not required for safety.

ASSEMBLY OUTLINE

Before You Start

Check the inventory list to be sure you have all necessary parts in good usable condition. Also check for any concealed damage.

Check the operation of the damper. The damper is controlled through the use of a damper rod inside the top center of the firebox opening, behind the lintel (Figure 3).

• To CLOSE the damper, PUSH the damper rod

UP and BACK (toward the rear of the fireplace), until locked in position.

• To OPEN the damper, PULL the damper rod

FORWARD (toward the front of the fireplace) and DOWN, until locked in position.

Optional

Outside Chase

Carefully consider the position of the fireplace opening with respect to the location of adjacent or nearby stairwells, bath or kitchen exhaust fans and/or return air registers for forced air furnaces/air conditioners that could cause a smoking fireplace condition if the house is tightly insulated.

When locating the fireplace, consideration must be given to combustibles and final finishing.

See

Figure 5 and confine the final location of combustible finish materials to the “Safe Zone.”

ASSEMBLY STEPS

Note: The following steps represent the normal sequence of installation. Each installation is unique, however, and might require a different sequence.

1. Position firebox prior to framing or into prepared framing.

2. Install the chimney system.

3. Install optional outside combustion air kit.

4. Plumb gas line if a decorative gas appliance will be used. (Gas connections should only be performed by an experienced, licensed/certified tradesman.)

5. Complete the installation, finish wall material, surround and hearth extension to your individual taste.

6. Assemble and attach optional glass door assembly.

Study the three dimensional illustration (

Fig-

ure 1 ) to get a general idea of each element of your fireplace system.

PRE-INSTALLATION NOTES

The fireplace may be installed directly on a combustible floor or raised on a platform of an appropriate height. Do not place fireplace on carpeting, vinyl or other soft floor coverings. It may, however, be placed on flat wood, plywood, particle board or other hard surfaces.

Be sure fireplace rests on a solid continuous floor or platform with appropriate framing for support and so that no cold air can enter the room from under the fireplace.

The fireplace may be positioned and then the framing built around it, or the framing may be constructed and the fireplace positioned into the opening.

Usually, no special floor support is needed for the fireplace, however, to be certain:

1. Estimate the total weight of the fireplace system including chimney and surround materials such as brick, stone, etc., to be installed. Shipping weights for the fireplace may be found on page 18.

2. Measure the square footage of the floor space to be occupied by the system, surrounds and hearth extensions.

3. Note the floor construction, i.e. 2 x 6’s, 2 x 8’s or 2 x 10’s, single or double joists, type and thickness of floor boards.

4. Use this information and consult your local building code to determine if you need additional support.

CAUTION: DO NOT BLOCK THE HEAT-CIRCU-

LATING AIR INLET AND OUTLET PORTS ON

CIRCULATING MODELS. DOING SO MAY RE-

SULT IN A POTENTIAL FIRE HAZARD.

If you plan to raise the fireplace and hearth extension, build the platform assembly then position fireplace and hearth extension on top.

Secure the platform to the floor to prevent possible shifting.

CLEARANCES

Minimum clearance to combustibles for the fireplace is as follows; sides and back – 1/2"

(13mm), combustible floor – 0" (0mm), adjacent wall 18" (457mm), adjacent shielded wall

(

K factor of .84 or less 40" W x 40" H ) 12"

(305mm), ceiling – 37-1/2" (953mm). Refer to page 17 for more detail.

Note: Clearance at the nailing flange for both fireplace models is 0" (0mm).

Note: Adjacent wall considerations are for an adjacent wall on only a single side. Walls should not be placed at minimum distance at both sides of the fireplace.

INSTALLING THE FIREPLACE

Step 1. Slide the fireplace into prepared framing or position fireplace in its final position and frame later.

The fireplace may not be recessed into a combustible floor. Maintain the floor to hearth clearance established by the fireplace lower front face.

Note: Safety strips are not required when fireplace rests on a noncombustible surface.

Note: Install the hearth extension only as illustrated (see Figures 43 and 44).


5

The safety strips should extend from front of the fireplace at least 1-1/2" and should extend to be at least flush with the sides. In the event a wooden support is used to elevate the fireplace above the floor, a “Z” type safety strip should be fabricated and used to protect the front surface of the wood support as well as the floor beneath the hearth extension ( Figures 8 and 9 ). The safety strips should be tacked down to prevent possible movement.

Note: The “Z” type safety strip is not supplied.

Note: The nailing flange and the area directly behind the nailing flange is exempt from the clearances described on the fireplace clearance label.

For Canadian Installations, Proceed with Steps 6 through 9

Step 6. Attach the cold climate kit, Model

FTF10-CCK1-LD, around the chimney collar with the screws provided ( Figure 19 ).

Step 7. Connect the 4" (102 mm) Class 0 air duct provided, to the collar on the chimney collar enclosure with the screws provided in the kit’s hardware package.

Step 8. Route the Class 0 air duct out the back or side wall, up through the ceiling or floor joists to an outside wall. The duct inlet should be located above snow level or above any anticipated snow level.

Enclosure Box

Step 2. Using standard construction framing techniques, construct openings for the chimney through the ceiling(s) and roof or through an outside chase. All framing must maintain the minimum air space clearance at all times.

CAUTION: ALLOW A MINIMUM 2" (51 MM)

CHIMNEY AIR SPACE TO COMBUSTIBLE FRAM-

ING MEMBERS THROUGHOUT VERTICAL AND/

OR OFFSET CHIMNEY INSTALLATIONS.

A minimum 2" (51 mm) air space must be reserved for all combustible and noncombustible materials extending for any continuous length surrounding the chimney.

Reference Figures 15 and 16 and charts “Framing Dimensions for Ceiling and Roof,” which specify minimum ceiling and roof dimensions.

For new construction, to determine chimney center line, use plumb line from ceiling or roof above fireplace to the center of fireplace flue collar.

For remodeling, plumb to the center of the fireplace flue collar from the ceiling or roof above. Drive a nail through the ceiling or roof from below to mark position. Mark and cut a hole in the ceiling (around the nail) ( Figure 20 ). Then plumb from ceiling or roof directly above the cut hole to determine roof hole position.

Figure 19

Note: If the fireplace is installed against an inside wall, the Class 0 air duct may be extended into a ventilated attic space at least 18"

(457 mm) above the attic floor. Secure the duct hood to a vertical post with the inlet positioned downward. Ensure that nothing blocks the hood opening. This duct must never terminate higher than the fireplace chimney.

Step 9. Cut or frame a hole through the outside wall for the installation of the duct inlet hood. A

4-1/2" (114 mm) diameter hole is required.

Feed the loose end of the flexible duct through the hole cut for the inlet hood and attach to the collar on the inlet hood using (2) two screws.

Insert the hood into the opening. Secure in place with nails driven through the holes in hood flange. Seal with noncombustible waterproof silicon type caulking. If additional duct is needed, use Class 0 metallic air duct.

INSTALLING THE CHIMNEY SYSTEM

Step 1. Check the flue damper for proper operation. When the flue damper is in the fully closed position, the damper control lever is pushed all the way to the rear of the firebox.

When the damper is in the fully open position, the flue damper control lever is pulled all the way to the front of the firebox.

Figure 20

Note: The optional collar duct kit, Model FTF10-

CDK, should be installed after the chimney has been attached to the flue collar.


Step 3. Position the appropriate firestop spacer at the ceiling and nail temporarily with two (2) 8d nails. Use a flat firestop spacer,

Model F10FS-2, for the FTF10 system if chimney penetrates vertically. If the chimney penetrates through the ceiling at a 30

°

angle (offset chimney) then use a 30

°

firestop spacer, Model

F10FS30-2. Use one nail on opposite sides of the firestop to hold in position. Nail permanently, using at least two (2) more 8d nails, after the chimney sections have been assembled through the firestop spacer and after necessary adjustments have been made. The firestop spacer must be secured in place by at least four

(4) 8d nails when completely installed.

Note: If there is a room above the ceiling level, the firestop spacer must be installed on the bottom side of the ceiling. If an attic is above the ceiling level, the firestop spacer must be installed on the top side of the ceiling joists

(Figures 21 and 22 ).

Note: For Canadian installations, all chimney installed outside the building must be constructed with galvalume (outer sections only) effective

January 1, 1992. The appropriate model designations are located in the back of this manual.

The FTF10 chimney system is a two piece chimney that snap locks together from the fireplace up. Always start with the inner flue section. With the lanced end up, snap lock the joint into the matching collar on top of the fireplace. At all subsequent joints, the upper flue section fits into the lower or preceding flue section. Each section snaps together by means of locking tabs (9 tabs per joint). Check each section by pulling up slightly from the top to ensure proper engagement before installing succeeding sections. If the flue has been installed correctly, it will not separate when tested. Also, the inner flue joint where each section is joined should be tight and flat without gaps (

Figure 26 ).

Note: All chimney sections are constructed with a unique locking tabs and hem design, which ensures and immediate, tight assembly between sections. Plan your chimney requirements carefully before assembly, as the chimney is difficult to disassemble after installation. If disassembled, the tabs might become damaged. Be certain that the tabs are properly formed to ensure they engage properly.

Note: Assemble one component of chimney at a time (inner section first; then outer section last) before preceding with the next complete section.

Continue to assemble the chimney up through framed opening. Assemble just enough to penetrate the roof flashing openings ( Figure 28 ).

Always maintain 2" minimum air space to combustible materials and always check each chimney joint (inner and outer) to ensure proper engagement. Check vertical alignment of chimney so that it projects from the roof in true vertical position.

Figure 28

Security's chimney sections do not need to be screwed together. Additional reinforcement is not necessary except in certain offset conditions (refer to page 12,

Figure 39 ).

Step 5. The height of vertical chimney pipe supported only by the fireplace must not exceed 30'. Chimney heights above 30' must be supported by a Model FTF10-S4 stabilizer installed at 30' intervals.

Note: The Model FTF10-S4 adds 3" net effective height to the total chimney system.

Install the Model FTF10-S4 stabilizer by fitting inner section down into respective section of proceeding flue pipe and locking outer stabilizer section into place over the outer chimney pipe. Position for proper clearance through framed opening and nail straps securely (under tension in “shear”) into place on framing. Use

8d nails. Attach successive lengths of chimney pipe directly to stabilizer using same techniques as described in Step 4 (

Figure 29 ).

Note: Do not apply excessive pressure to any subsequent chimney sections following the stabilizer when installing. Ensure each subsequent chimney section is securely attached by testing as noted in Step 4.

Step 6. Select the proper Security Chimneys roof flashing based on pitch of roof. Use chart below for selection:

Step 8. The standard Security FTF10 roof flashing assemblies include a storm collar. Slide the storm collar over outer chimney, rest on flashing spacers and align with top surface of flashing. Insert tab in slot, pull tight and bend tab back over slot. Seal storm collar to outer chimney with roof caulking or mastic around entire circumference of pipe. Also add extra roof caulking to the tab/slot area to seal completely against water penetration ( Figure 32 ). Check all joints very carefully to ensure no water intrusion can take place.

Next, slide roof flashing over extended chimney section that previously has been installed above the roof opening in Step 4. FTF10 flashings require flashing spacers. Slide flashing all the way down until the flashing base rests flat on the roof ( Figure 30 ). Again, check the vertical position of the chimney and the 2" minimum air space to combustibles.

Note: Do not caulk or seal the ventilating openings.

Step 7. Secure flashing by nailing along the perimeter into roof using 8d nails. If shingled roof, slide upper end and sides of roof flashing under shingles (trim if necessary), seal the top and both sides of the flashing to the roof with roof caulking. Cover nail heads with roof caulking ( Figure 31 ).

Figure 32

Step 9. Security Chimneys locking bands,

Model FLB, may be required if the chimney extends too high above the roof flashing. As a general rule, if the chimney extends more than

6' above the roof flashing, the use of locking bands is advisable to strengthen the chimney assembly. Align the locking band at the chimney joint. Locking bands wrap around pipe joints equally covering the joints of both pipe sections. Use the nut provided and TIGHTEN snugly. Do not overtighten as this might damage the chimney section ( refer to Figure 29 ).

Note: If chimney extends more than 8' above roof surface, guy wires are also recommended.

Use three (3) guy wires, attach to locking band assembly, extend and secure to roof in a triangular pattern (Figure 33 ). Guy wires are not supplied by the manufacturer.

Step 10. Installing a FTF10 CTDTM Round

Termination:

1. Hold the FTF10 CTDTM over the top of the last chimney section installed (

Figure 34 ).

2. Center the inner slip section into inner flue pipe and slip down.

3. Center the outer locking section over outer flue pipe. Push down until all locking tabs are firmly engaged and locked.

4. Pull up slightly on CTDTM to ensure the locking joint is firmly engaged and locked.

Using a FTF10-CT1 Chase Termination:

Refer to specific installation instructions included with FTF10-CT1 chase terminations for clearance and installation details.

Using a FTF10-CT2 Chase Termination:

Refer to specific installation instructions included with FTF10-CT2 chase terminations for clearance and installation details.

(508mm)

Note: It is recommended that all exterior exposed metal fireplace components; such as terminations, flashings, storm collars and/or flue be painted with a premium quality, high temperature, rust preventative paint designed for metal. This is especially important when installations are made in abnormally adverse or corrosive environments; such as near lakes, oceans or in areas with consistently high humidity conditions. Consult the paint manufacturers instructions for proper preparation and application.

TEN FOOT RULE SUMMARY

The minimum chimney height above the roof and/or to adjacent walls and buildings is specified by all major building codes.

If the horizontal distance from the peak of the roof is less then 10', the top of the chimney must be at least 2' above the peak of the roof.

If the horizontal distance from the chimney edge to the peak of the roof is more than 10' a chimney height reference point is established on the roof surface 10' horizontally from the chimney edge. The top of the chimney must be at least 2' above this reference point. In all cases, the chimney cannot be less then 3' above the roof at the edge of the chimney.

The 2' in 10' rule is necessary in the interest of safety but does not ensure smoke-free operation. Trees, buildings, adjoining roof lines, adverse wind conditions, etc., may require a taller chimney should the fireplace not draft properly ( see Figure 35 ).

MULTIPLE TERMINATIONS

If more than one termination is located in the same chase or within the same general proximity, we suggest they should be separated in distance at least 24" horizontally from flue center to flue center and stacked or staggered vertically at least 18" apart, from the termination of one smoke exit to the termination of another smoke exit ( Figure 36 ).

This suggestion is provided in the interest of better operation. If the terminations are located too close to each other, smoke may migrate from one flue into the other.

CALCULATIONS

The minimum installed height of the completed fireplace system is 15' 0". The maximum height is 60' 0".

To determine the number of chimney sections and chimney components required, follow these steps:

1. Determine total vertical height of the fireplace installation. This dimension is the distance from the surface the fireplace sets on to the point where smoke exits from the termination.

2. Determine the number of chimney components required, except chimney sections. This would include firestop spacers, stabilizers, roof flashing, etc.

4. Determine amount of chimney height required by subtracting total combined height of all pre-selected components (fireplace and chimney components from total desired height.)

Reference Vertical Elevation Chart and determine the number of chimney sections (quantity and length) required.

SPECIAL OFFSET INSTRUCTIONS

To clear any overhead obstructions, you may offset your chimney system using Security's

30

°

offset and return elbows. Use two elbows an offset elbow to initiate the offset and a return elbow to terminate it. A 30

°

offset elbow, angling in any direction, may be the first component used off the top of the fireplace flue collar.

The offset and return elbows may be attached together, or a section or sections of chimney may be used between, but do not exceed 20' in total length between elbows. If sections of pipe exceed 10' between elbows, a chimney stabilizer must be used at the midpoint (

Figure

37 ). The stabilizer support straps must be attached under tension (in shear) to structural framing members above. When two sets of elbows are used, the maximum combined length of chimney used between elbows cannot exceed 20' ( Figure 38 ). Example: If C

1

10' then C

2

cannot exceed 10'.

=

If an offset exceeds 6' in length, each chimney joint beyond the first 6' of offset to the return elbow, must be secured by a No. 8 x 1/2" sheet metal screw located at the underside of the joint ( Figure 39 ).

A 1/8" diameter hole must be drilled in the chimney joint using a 1/8" diameter drill. Hole should be drilled in center of joint overlap ( see

Figure 40 ). Be sure to drill only through the outer chimney casting. Do not puncture the inner flue.

Maximum offset of chimney system is 30

°

.

Two offsets must not be assembled to form a

60

°

offset. However, two sets of offset and return elbows may be used on a single flue system, provided the total height of the system exceeds 25'.

Return elbow support straps must be securely attached under tension (in shear) to structural framing members above. Do not substitute a

FTF10-30 offset elbow in place of a FTF10-E30 return elbow.

OFFSET CALCULATIONS

Step 1. Use Offset Chart to determine amount of horizontal offset (A) and height (B) for various chimney section assemblies.

Step 2. Use “Height of Chimney Only” column in The Vertical Elevation Chart to determine combinations of chimney used above return elbow to achieve desired heights. Reference

Components Effective Height Chart in vertical elevation chart section on page 13.

Step 3. Use Elevation Chart as job estimator only. Add necessary firestop spacers and stabilizers as required. Firestop spacers must be used as shown in

Figures 23 and 24 and stabilizers as shown in Figure 29.

INSTALLING OFFSETS

First, review the Offset Elevation Chart and

Figure 41 for reference.

Step 1. Determine the offset distance where chimney is to pass through the first ceilingdimension “A.” To find this point on your ceiling, first determine the center point for a vertical chimney following the instructions for vertical installation.

Measure height to the ceiling from the top of fireplace-dimension “B.” Use the appropriate

Offset Elevation Chart to find dimension “A.”

Mark point where you will drive your nail to show the center point for your offset ceiling cut.

Step 2. Proceed by using the Straight Up Installation Instructions for cutting and framing ceiling and roof openings.

Note: See Framing and Dimension Chart for the sizes of the ceiling and roof openings. The size of the roof opening varies with the degree of pitch of the roof.


Offset Elbow Assembly

Offset elbows install the same as chimney sections. First, snap the inner section INTO the preceding inner section of flue. Check connection by pulling up slightly to ensure a tight fit.

Next, the outer sections snap lock OVER the preceding outer section of chimney. Again, check outer section by pulling up slightly to ensure proper connection is made.

Return Elbow Assembly

Return elbows install the same way as round terminations and stabilizers:

Step 1. Hold return elbow over top of last chimney section.

Step 2. Center inner slip section into inner flue pipe-slip down.

Step 3. Center outer-locking section over outer chimney pipe. Push down until locking joint has firmly engaged.

Step 4. Pull up slightly on return elbow to ensure locking joint has firmly engaged.

Step 5. Secure support straps to framing members by nailing under tension in sheer

( Figure 42 ).

Return

Elbow

Figure 42

Note: The return elbow assembly performs the same function as a stabilizer. Consider this when determining the need for a stabilizer.

Note: Do not apply excessive pressure to any subsequent chimney section following return elbow assembly when installing. Ensure that each subsequent chimney section is securely attached by testing as noted above.

Combustion Air Kits

You may use the combustion air kit, Model

FOAK-4 or FOAK-4LD, with the LBR/LBC Series fireplaces. Refer to the installation instructions packed with the air kit for specific installation information. The outside air kit must be installed before the fireplace is totally framed and enclosed within the finished walls.

The combustion air kit provides for outside air to be drawn into the fireplace as an aid for combustion. If installed, only one combustion air kit is needed and it will be installed on the left side of the fireplace. If additional length of air duct is necessary, purchase locally available

U.L. Class 0 or Class 1 metallic duct. The duct may extend up to 50' (15.24 m) in any direction.

Note: When installing the air duct vertically,

DO NOT terminate the air duct closer than 3'

(914 mm) below the chimney top.

There is a hand operated shut-off lever located in the left side of the fireplace opening behind the screen. To open, pull all the way. The combustion air damper should be fully open when the fireplace is in use and completely closed when the fireplace is not being used. This will prevent outside cold air from entering the dwelling.

Operate the actuator through several cycles including the "lock position. Ensuring proper operation and freedom of movement. Return the actuator arm to the locked position.

CAUTION: NEVER LOCATE THE AIR INLET

WHERE IT COULD BE BLOCKED BY SHRUBS,

SNOWDRIFTS, ETC. NEVER LOCATE AIR INLET

IN A GARAGE OR IN ANY AREA WHERE THERE

IS ANOTHER FUEL BURNING APPLIANCE OR

PRODUCTS EMITTING COMBUSTIBLE GASES

SUCH AS PAINT, GASOLINE, ETC. IN COLD

CLIMATES IT IS RECOMMENDED THAT THE

COMBUSTION AIR DUCT BE INSULATED.

The outside air ducting may be installed upwards through framing and ceiling joists, with the inlet hood installed through an outside wall. Air ducting may also be installed downward through floor joists and under the dwelling to a ventilated crawlspace not considered part of the living area.

Note: Do Not terminate the combustion air kit in an attic space under any circumstances.

Forced Air Kit

If you are installing the Lennox Forced Air Kit,

Model LFAK-2000, see the instruction sheet provided with the kit for electrical wiring requirements. The fireplace has been pre-wired at the factory but must be connected to main power supply at the time of installation if the

LFAK-2000 is to be installed later. The electrical connections must be made before the fireplace is framed and enclosed in the finished walls.

CAUTION: ELECTRICAL CONNECTIONS

SHOULD ONLY BE PERFORMED BY A QUALI-

FIED, LICENSED ELECTRICIAN. MAIN POWER

MUST BE OFF WHEN CONNECTING FANS TO

MAIN ELECTRICAL POWER SUPPLY OR PER-

FORMING SERVICE.

Variable Speed Wall Switch

Refer to the installation instructions provided with the Variable Speed Wall Switch, Model

VSWS, for installation details.

OPTIONAL EQUIPMENT

CONSIDERATIONS

Gas Line Connection

Always plumb gas line installation per local codes. Check all connections with soap suds; leaks will bubble. Never test any gas line connection with a match or open flame.

This provision is intended for connection to a decorative gas appliance incorporating an automatic shut-off device and complying with the

Standard for Decorative Gas Appliances for installation in vented fireplaces, ANSI Z21.60

(1991) or American Gas Association draft requirements for Gas-Fired Log Lighters for Wood

Burning Fireplaces, Draft No. 4 dated August,

1993. Install in accordance with the National

Fuel Gas Code, ANSI Z223.1. This complies with the revised U.L. 127 standard.

Vent Free Appliances

These units have been tested and approved to

ANSI/IAS/AGA Z21.11.2 for use with unvented gas appliances and complies with the standard for Factory-Built fireplaces, UL 127.

The unit has been tested for use with any unvented gas log sets having a maximum rating of 40,000 BTU. The minimum mantle configurations are outlined in Figures 43 and 44.

These fireplaces have been marked with a maximum rating of 40,000 BTU to assure that homeowners do not exceed the allowable limits for all allowed installations of mantles.

NEVER INSTALL AN UNVENTED GAS LOG

SET WITH A BTU GREATER THAN 40,000.

CAUTION: WHEN USING THE DECORATIVE

GAS APPLIANCE, THE FIREPLACE DAMPER

MUST BE SET IN THE FULLY OPEN POSITION.

CAUTION: PLUMBING CONNECTIONS SHOULD

ONLY BE PERFORMED BY A QUALIFIED, LI-

CENSED PLUMBER. MAIN GAS SUPPLY MUST

BE OFF WHEN PLUMBING GAS LINE TO FIRE-

PLACE OR PERFORMING SERVICE.

If you’re installing a gas line, connect it before the fireplace is framed and enclosed in the finished wall. The gas knockout is determined by the indentation located at the bottom and slightly off center in the side refractories. THE

KNOCKOUT IS ALWAYS REMOVED FROM IN-

SIDE THE FIREPLACE. DO NOT REMOVE THE

KNOCKOUT UNLESS YOU ARE INSTALLING A

GAS LINE. If removal is attempted from the outer wrapper, side refractory damage may occur. With a medium-sized hammer, lightly tap the surface of the indentation. The refractory material is very thin in this area and is easily removed. Once a small hole has been made, continue tapping until you have reached sufficient diameter for the gas line to fit through. The entire knockout does not have to be removed.

Remove insulation in the gas line channel.

IMPORTANT: REPACK INSULATION MATERIAL

IN SQUARE HOLE AROUND GAS LINE, INTE-

RIOR AND EXTERIOR OF FIREPLACE, TO SEAL.

Glass Doors

If glass doors are to be installed on these fireplaces, refer to specific installation instructions packed with the glass doors. Use only the doors that are listed for use with these fireplaces. Use of other non-listed glass door on these fireplaces may constitute a potential fire hazard and is not recommended.

CAUTION: CERTAIN GLASS DOORS OVER-

LAP THE BLACK METAL FACING OF THE FIRE-

PLACE. IF THE FIREPLACE HAS BEEN FACED

WITH NONCOMBUSTIBLE MATERIALS,

THERE MIGHT NOT BE SUFFICIENT CLEAR-

ANCE TO INSTALL THE GLASS DOORS OF

YOUR CHOICE. ENSURE ADEQUATE CLEAR-

ANCE IS MAINTAINED AT ALL TIMES SO AS

NOT TO INTERFERE WITH THE INSTALLA-

TION AND OPERATION OF GLASS DOORS.

COLD CLIMATE INSULATION

If you live in a cold climate, it is especially important to seal all cracks around the fireplace opening with noncombustible material and wherever cold air could enter the room.

Surrounding materials must be caulked where it meets the black metal facing of the fireplace to avoid cold air intrusion. Use noncombustible caulking material only on fireplace facing to seal. Also, the outside air inlet duct should be wrapped with noncombustible insulation to minimize the formation of condensation. Do not place insulation materials on top of fireplace or against chimney sections.

Note: A 2" air space must be preserved for all combustible materials extending for any continuous length adjacent to the chimney.

It is especially important to insulate between the studs of an outside chase cavity and under the floor if the floor is above ground level. Do not place insulation directly against the fireplace or chimney system.

The installation of the CCK1 is recommended.

Refer to Steps 6 thru 9 on Page 8.

FIREPLACE FINISHES

It is sometimes best to frame your fireplace after it is positioned and the chimney is installed. Frame enclosure for chimney and fireplace with 2 x 4’s (or heavier) lumber.

Note: The header may rest on the two (2) metal top spacers on top of the unit but the header must not be notched to fit around the spacers.

Mantels and Trim

These fireplaces may sit directly on a combustible surface. A 2" air space is required between combustible framing and the chimney. In

Canada, the minimum height for a combustible mantel is 18" (457 mm) above the fireplace opening. Figure 43 shows typical Canadian installations. For installations other than Canada, combustible mantels and trim may either project in front or be flush with the finished wall as per

NFPA 211 section 7-2.3.3. and Figure 44.

If a mantel is of a noncombustible material, it is exempt from these requirements as long as it does not interfere with the installation or operation of glass doors, or block the air circulating opening of the fireplace

Hearth Extensions and Wall Shields

A hearth extension must be installed with all fireplaces. It is to protect the combustible floor in front of the fireplace from both radiant heat and sparks. The hearth extension must extend 12" beyond both sides of the fireplace opening and 20" beyond the front ( see Figure

45 ). Use a hearth extension constructed of a durable noncombustible material having an equal or better (lower k value) insulating value of k = .84 BTU IN/FT

However, the manufacturer of the material must provide either the listed kvalue per inch or r-value per inch with listed thickness so that the minimum thickness required for the hearth can be calculated (per instructions on this

Page and/or as specified in the NFI Certification manuals).

Note: Also see NFI (National Fireplace Institute) Certification Manuals showing other acceptable calculation methods and acceptable alternate materials which can be used.

Note: Any noncombustible material whose k value is less than .84 or whose r value is more than 1.19 is acceptable.

If the fireplace is installed on a combustible floor, use the metal safety strips (provided) on the floor extending half under the fireplace and half under the hearth extension

(refer to Figures 6 & 7).

A wall shield is required where a continuous perpendicular side wall is within 12" of the fireplace opening ( Figure 46 ). Use a 36" W x

36" H wall shield constructed of a durable, noncombustible material having an equal or better (lower k value) insulating value than k =

.54 BTU IN/FT 2 HR

°

F. At no time may a perpendicular side wall be located closer than

9" from the fireplace opening.

If fireplace is installed diagonally across a 90

° corner; no wall shields are required.

Calculating Minimum Thickness if Multiple

Materials are Used

At times it is important to know what combination of materials are acceptable for use as floor protection. The “R values” are used to determine acceptable combinations of materials because “R values” are additive where r and k values are not.

“R value” = 1/k = “r” x thickness of material used

Example: Given that the required “R value” for a suitable floor protector used must be equal to or greater than:

“R” = r

L

x T

L

= 1.19 x 1” = 1.19.”

If it is desired to elevate a marble hearth extension to a level of 5” or more above the floor surface. What combination of noncombustible materials can be used to accomplish this?

If common brick is used so that the 3 1/2” dimension is the height, “R” for the common brick becomes:

brick

“R”

M

= r

M

x T

S

= 0.20 x 3 1/2" = .70

Using 1/2” of mortar to set the brick, “R” for the mortar is calculated as follows:

mortar

“R”

M

= r

M

x T

S

= 0.20 x 1/2" = .10

Next, a 3/4" marble slab set in 1/2" mortar covers the brick, “R” for the marble and mortar becomes:

marble

“R”

M

= r

M

x T

S

= 0.05 x 3/4" = .038

mortar

“R”

M

= r

M

x T

S

= 0.20 x 1/2" = .10

The sum of all “R values” is: .70 + .10 +. 038

+ .10 = .938

This would NOT be an acceptable combination of material for the hearth extension since the total calculated “R value” of the materials used is under the required “R value” of 1.19. An additional layer of insulating materials must be used.

Note: Also see NFI Certification Manuals for expanded explanation on calculating “R values” when multiple materials are used.

FINISH TO YOUR TASTE

There are a wide variety of “finished looks” for these fireplaces, from formal wall decor with elaborate mantels to rustic wood paneling or warm brick facings.

Only noncombustible materials like stone, tile, brick, etc., may overlap the black front facing.

Do not extend these materials beyond the black facing and into the firebox area. Be sure not to interfere with the installation and operation of glass doors or block the upper or lower grilles.

Seal all joints between the black facing and wall surrounds to prevent air intrusion. Use noncombustible caulking material only to seal the black metal facing to the surround material on the finished wall.


Combustible materials may project beyond the sides of the fireplace opening as long as they are kept within the shaded area, as illustrated in Figure 49 for LBR models and

Figure 50 for LBC models.
