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.

2

3.These fireplaces must be installed with either Security Chimneys model FTF8 (8" [203mm] inside diameter) or FTF10 (10" [250mm] 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.Toensureasafefireplacesystemandtoprevent 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 a 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 an that 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.

NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.

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.

PRECAUTIONS

Note: These fireplace systems are not difficult to install. However, in the interest of safety, it is recommended that the installer be a qualified or certified “tradesman” familiar with commonly accepted fireplace installation and safety techniques as well as prevailing local codes.

The most important areas of concern dealing with the installation of factory-built fireplaces are clearances to combustible materials, proper assembly of component parts, height of the chimney system, the proper use of accessories supplied by the manufacturer and the techniques employed in using finishing materials applied to the wall surrounding the fireplace, hearth extensions and wall shields. Each of these topics will be covered in thorough detail throughout this manual. Please give each your special attention as you progress with your installation.

INTRODUCTION

General Information

These fireplaces are conventional radiant heat fireplaces with standard bar grates, optional outside combustion air kits and optional decorative glass doors.

These fireplaces have been tested and listed by Omni Test Labs (Report No.116-F-20-4) to U.L. standard 127. These units are intended for installation in residential homes and other buildings of conventional construction including commercial, not in mobile homes.

Note: Illustrations shown reflect “typical” installations with nominal dimensions and are for design and framing reference only. Actual installations may vary due to individual design preferences. However, always maintain minimum clearances to combustible materials and do not violate any specific installation requirements.

These fireplace systems are designed for installation in accordance with the National Fire Protection Standard for chimneys, fireplaces and solid fuel burning appliances; NFPA 211 and in accordance with codes such as the BOCA Basic/National Codes, the Standard Mechanical Code and the Uniform Building Codes.

WARNING: FAILURE TO USE MANUFACTURE PROVIDED PARTS, VARIATIONS IN TECHNIQUES AND CONSTRUCTION MATERIALS OR PRACTICES OTHER THAN THOSE DESCRIBED IN THIS MANUAL MAY CREATE A FIRE HAZARD AND VOID THE LIMITED WARRANTY.

CLEARANCES AND HEIGHT

REQUIREMENTS

The fireplace may be placed on or near normal construction materials*. The combustion air kit, firestop spacer and roof flashings (not chase flashings) may be placed directly on or against normal construction materials*. The chimney requires a minimum 2" (51 mm) air space to combustibles (See **Note). A combustible mantle may be installed 12" (305 mm) above the opening of the fireplace as per NFPA 211, Section 7-3.3.3. In Canada the minimum is 18" (457 mm) above the opening.

The fireplace and chimney system must be enclosed when installed in or passing through a living area where combustibles or people may come in contact with it. This is important to prevent possible personal injury or fire hazard.

For questions, please call your distributor or the manufacturer. Special restrictions apply to the front and facing of the fireplace and nearby walls (See pages 16, 17 and 18 ).

CHIMNEY SYSTEM

These fireplaces are designed and code listed for use with Security's FTF8 and FTF10 chimney System only. Always use Security's FTF8 and FTF10 chimney components with these fireplaces. Do not modify or alter these components as this may cause a potential serious hazard and void the Warranty.

*Construction Materials:

 

• framing materials

• paneling

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

Check the operation of the damper. The damper is controlled through the use of a control lever located within the firebox opening at the top center just behind the firebox lintel (Figure 3 ). The control lever snaps into place at the extreme range of motion, up and back in the closed position. When pulled forward and down, the damper is open.

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.Connect house wiring to the fireplace for later attachment of optional blower.

4.Install optional outside combustion air kit.

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

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

7.Assemble and attach optional glass door assembly.

Study the three dimensional illustration (Figure 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 RESULT 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 appliance is as follows: sides and back - ¹⁄ " (13 mm), floor - 0" (0 mm), adjacent wall - 12" (305 mm), ceiling - 37 ¹⁄ " (953 mm).

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.

Step 2. Insert the provided metal safety strips, beneath the fireplace as illustrated (Figures 6, 7 and 8 ). The safety strips should overlap ¹⁄ " for continual coverage of the floor.

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

Note: Install the hearth extension only as illustrated.

The safety strips should extend from front of the fireplace at least 1 ¹⁄ " 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.

IMPORTANT: UNDER NO CIRCUMSTANCES CAN THE FIREPLACE TOP SPACERS (FIGURE 6 ) BE REMOVED OR MODIFIED, NOR MAY YOU NOTCH THE HEADER TO FIT AROUND OR BE INSTALLED LOWER THAN THE SPACERS. THE HEADER MAY BE IN DIRECT CONTACT WITH THE TOP SPACERS BUT MAY NOT BE SUPPORTED BY THEM.

Note: The framed depth, 21 ³⁄ " (552 mm) from a framed wall, must always be measured from a finished surface. If a wall covering such as drywall is to be attached to the rear wall, then the 21 ³⁄ " (552 mm) must be measured from the drywall surface. It is important that this dimension be exact.

If the appliance is to be elevated above floor level, a solid continuous platform must be constructed.

The header may rest on the top metal spacers, but must not be notched to fit around them.

Consult all local codes.

For Canadian Installations Proceed with Steps 4 through 7.

Step 4. Attach the chimney collar enclosure kit, Model CCK1, around chimney collar with the screws provided (Figure 10 ).

Step 6. Route the Class 0 air duct out the back wall or side wall, up through the ceiling or floor joists to an outside wall. The air duct should be located above snow level.

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 nothing blocks the hood opening. This air duct must never terminate higher than the chimney.

Step 7. Cut or frame hole through the outside wall for the installation of the duct inlet hood. A 4 ¹⁄" (114 mm) diameter hole is sufficient. Feed the loose end of the flexible air duct through the hole cut for the inlet hood and attach to collar on inlet hood using two (2) screws. Insert hood into opening. Secure in place with nails driven through holes in hood flange. Seal with noncombustible waterproof silicon type caulking. If additional air duct is needed, use Class 0 metallic air duct.

Step 8. Fireplace should be secured to side framing members using the full length nailing tabs at the top and bottom of the fireplace front face. Use 8d nails (Figure 18 ).

8d Nail

Figure 18

Note: The nailing tabs and the area directly behind the nailing tabs are exempt from the clearances described on page 5. Maintain at least 1/2" clearance from the firebox wrapper to the framing at the closest point of contact, directly adjacent to the flange.

Step 1. Before continuing, check the operation of the damper, as described on page 4, (refer to Figure 3 ).

Step 2. Using standard construction framing techniques, construct opening for chimney route up through the ceiling(s) and roof or through an outside chase.

Framing must maintain adequate minimum air space clearance at all times.

CAUTION: ALLOW MINIMUM 2" (51 MM) CHIMNEY AIR SPACE TO COMBUSTIBLE FRAMING MEMBERS THROUGHOUT VERTICAL OR OFFSET CHIMNEY INSTALLATION (SEE **NOTE).

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

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

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

For remodeling, plumb to center of flue collar from ceiling above, drive nail through ceiling from below to mark position, then mark and cut to passage from above ceiling (around nail) (Figure 19 ). Then plumb from ceiling or roof level directly above hole which has just been completed.

NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.

Note: If installing the optional collar duct kit, it should be installed after the chimney has been attached to the flue collar.

Step 3. Position appropriate firestop spacer at ceiling and nail temporarily with two (2) 8d nails. If chimney penetrates ceiling vertically, use flat firestop spacer, Model F8FS-2 for FTF8 system and Model F10FS-2 for the FTF10 system*. If chimney penetrates ceiling at 30° angle (offset chimney), use 30° firestop spacer, Model F8FS30-2 for FTF8 and Model F10FS30- 2 for FTF10 system*. Use one nail on opposite sides to hold firestop spacer in position. Nail permanently, using at least two (2) more 8d nails, after chimney sections have been assembled through the firestop spacer and after any necessary adjustments have been made. Firestop spacer must be secured by at least four (4) 8d nails when completely installed.

Note: If there is a room above ceiling level, firestop spacer must be installed on the bottom side of the ceiling. If an attic is above ceiling level, firestop spacer must be installed on top side of ceiling joist (Figures 20 and 21 ).
