to ensure homeowner comfort by providing supplemental heat to its immediate area.

11. Keep screens closed after feeding ﬁ re to

keep embers from ﬂ ying out ot ﬁ replace.

12.INDOOR INSTALLATIONS:

• Always ensure that an adequate supply of replacement combustion air from the outside of the house is accessible to the ﬁ re 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 efﬁ cient features, the optional outside air kit may not provide all the air required to support combustion.

NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.

• 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 ﬁ replace.

• An Outside Air Cover (provided) or an Out- side Air Kit Gate, model OAKG-OD (optional) must be installed to prevent signiﬁ cant cold air inﬁ ltration.

13. Always ensure that the air inlet to the ﬁ replace is free from debris and any other obstructions that can block the entrance of air.

14. DO NOT use a ﬁ replace insert or any other product not speciﬁ ed by Lennox for use with this ﬁ replace. 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.

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

16.Never, under any circumstances, install a ﬁ replace, chimney component or any accessories, that has visible or suspected physical damage as a result of handling or transportation.

PRECAUTIONS

The most important areas of concern dealing with the installation of factory-built ﬁ replaces 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 ﬁ nishing materials applied to the wall surrounding the ﬁ replace, 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.

Note: These ﬁ replace systems are not difﬁ cult to install. However, in the interest of safety, it is recommended that the installer be a qualiﬁ ed or certiﬁ ed “tradesman” familiar with commonly accepted ﬁ replace installation and safety techniques as well as prevailing local codes.

INTRODUCTION General Information

These ﬁ replaces are traditional radiant heat ﬁ replaces with standard bar grates, optional Outside Air Kits (required for outdoor installations) and optional Operable Bi-Fold Stainless Outdoor Glass Doors and Weather Cover.

These appliances are approved for installation indoors or outdoors.

Indoors: These appliances are approved for installation in residential homes and other buildings of conventional construction including commercial, not in manufactured homes(see Figure 5).

Outdoors: These appliances are approved for installion against an outside wall of a house, or as a freestanding ﬁ replace on the porch, patio, or located in the yard (see Figure 6). The Outdoor Fireplace must be enclosed to prevent impact damage to the outside of the ﬁ replace. Build an outside enclosure out of standard building materials, being careful to maintain the minimum air clearances speciﬁ ed in these Installation Instructions. When installing the ﬁ replace as a freestanding unit on your porch, patio or backyard, it must also be enclosed to prevent impact damage to the ﬁ replace. However, the enclosure must now be ﬁ nished on all four (4) sides. The exterior of the enclosure may be ﬁ nished in a textured plywood, a wood clapboard siding, brick, or a cultured stone.

Vinyl siding is not recommended for use on the front of the ﬁ replace due to the heat the unit produces. This can cause the vinyl siding to deteriorate.

Note: Illustrations shown reﬂ ect “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 speciﬁ c installation requirements.

These ﬁ replaces have been tested and listed by OMNI-Test Laboratories, Inc. (Report No. 116-F-35-2) to U.L. 127 (USA) and U.L.C. S610 (Canada). These units are intended for indoor and outdoor installations as speciﬁ ed in this manual.

For installations in Canada, the chimney clearance to combustibles must be 2 inches and the Cold Climate Kit must be installed.

WARNING

Do not pack or ﬁ ll required air spaces with insulation or other material. No material is allowed in these areas.

AVERTISSEMENT

Ne remplissez pas les espaces libres d’une matière isolante ou de tout autre type de matériel. Aucun matériel n’est permis dans ces espaces vides.

WARNING

If insulation is used, the ﬁ replace must not be placed directly against it. Insulation or vapor barriers, if used, must ﬁ rst be covered with gypsum board, plywood, particle board or other material to assure insulation and vapor barriers remain in place.

AVERTISSEMENT

Si un isolant est utilisé, il ne doit pas venir en contact avec le foyer. L’isolant ou le coupe vapeurs, si utilisée, doit d’abord être couvert d’un panneau de gypse, contreplaqué, panneau de particules ou d’un autre matériel pour s’assurer que l’isolant et le coupe vapeurs demeurent en place.

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

 Notes (Table 2)

• Outdoor ﬁ replace system less than 15 feet height must be a minimum of 10 feet away from a building or combustible structure. The 10 foot rule applies on all cases (see ten foot rule summary on Page 15).

• The system height may be reduced to a single length of FTF8-48 pipe and termination with either the FTF8-CTD or FTF8-CTDT for a minimum height on a complete system of 7' 3." The ﬁ replace must be installed as a Freestanding system and located a minimum of 10' away from any building or structure (refer to Figure 1).

• The minimum height will vary when using other Firecraft or Lennox Terminations.

Chase Enclosure

A chase is a vertical box-like structure constructed to surround the ﬁ replace and chimney. Refer to Figure 4 for a typical chase conﬁ guration. 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 ﬂ oor beneath the ﬁ replace and the chase bottom. Chase insulation in a cold climate installation is not required for safety.

Note: Do not insulate the chase cavity with blown or ﬁ ll type insulation materials.

Note: Local codes may not require ﬁ restopping at the ceiling levels for outside chase installations. However, it is recommended for safety and the reduction of heat loss.

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 ﬁ rebox opening at the top center in front of the ﬁ rebox lintel (Figure 3). The control lever snaps into place at either extreme of its range of motion. When locked in position all the way to the right, the damper is open. When locked in position all the way to

the left, the damper is closed.

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 ﬁ rebox prior to framing or into

prepared framing.

2. (Outdoor Installations) Waterproof the

ﬁ replace. See Waterprooﬁ ng The Fireplace on Page 6.

3. Install the chimney system.

4. Install an outside air cover or an airgate kit, if

ﬁ replace is being installed indoors (optional accessory, see Page 23 for ordering information). The Airgate kit is required on all

INDOOR installations when an outside air kit is installed. The Airgate Kit is NOT approved for use on outdoor installations.

5. Install outside air kit (provided). This kit

is required on ALL outdoor installations (optional for indoor installations).

6. Plumb gas line if a decorative gas appliance

will be used. (Gas connections should only be performed by an experienced, licensed/ certiﬁ ed tradesman).

7. Complete the installation, ﬁ nish wall mate-

rial, surround and hearth extension to your individual taste.

8. Assemble and attach optional glass door

assembly.

Study the illustration of the installation, Figures 1 & 2, to get a general idea of each element of your ﬁ replace system.

PRE-INSTALLATION NOTES

The ﬁ replace may be installed directly on a combustible ﬂ oor or raised on a platform of an appropriate height. Do not place ﬁ replace on carpeting, vinyl or other soft ﬂ oor coverings. It may, however, be placed on ﬂ at wood, plywood, particle board or other hard surfaces. Be sure ﬁ replace rests on a solid continuous ﬂ oor or platform with appropriate framing for support (and for indoor installation ensure that no cold air can enter the room from under the ﬁ replace).

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

Usually, no special ﬂ oor support is needed for the ﬁ replace, however, to be certain:

1. Estimate the total weight of the ﬁ replace system including chimney and surround materials such as brick, stone, etc., to be installed. Shipping weight for the ﬁ replace may be found on Page 9 (see Product Reference Information).

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

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

4. Use this information and consult your local

building code to determine if you need additional support.

If you plan to raise the ﬁ replace and hearth extension, build the platform assembly then position ﬁ replace and hearth extension on top. Secure the platform to the ﬂ oor to prevent possible shifting.

WATERPROOFING THE FIREPLACE

Outdoor Installations

Although the ﬁ replace is designed to drain to the front most of the water from rain and other sources that may enter the hearth area, condensation and unusual conditions may cause water to collect inside the ﬁ replace bottom.

To prevent water collection, the builder must provide a means to drain water from under

the ﬁ replace by building or installing a water collector of the builder's choice before positioning the ﬁ replace on its location.

INDOOR INSTALLATIONS ONLY

Outside Air Cover

If the optional outside air kit is not required in an indoor installlation, you must install the outside air cover to close the opening for the outside air kit (see Figure 8, Photo C).

Step 3. Refer to ﬁ replace drawings and speciﬁ cations (see Figures 18, 19 & 20) for framing dimensions and details. Frame appliance enclosure as illustrated in Figure 18.

Note: The framed depth, 20 5/8" (524 mm) from a framed wall, must always be measured from a ﬁ nished surface. If a wall covering such as drywall is to be attached to the rear wall, then the 20 5/8" (524 mm) must be measured from the drywall surface. It is important that this dimension be exact.

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

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

Consult all local codes.

A minimum 1"* air space must be reserved for all combustible materials extending for any continuous length surrounding the chimney.

*Note: 2" clearance to combustibles required in Canada. 2” déblayage aux combustibles exigés au Canada.

Reference Figures 19 & 20 and charts Framing Dimensions for Ceiling and Roof, which specify minimum ceiling and roof dimensions.

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

Notes: Indoor Installations: If there is a room above

ceiling level, ﬁ restop spacer must be installed on the bottom side of the ceiling. If an attic is above ceiling level, ﬁ restop spacer must be installed on top side of ceiling joist (Figures

29 & 30).

Outdoor Installations: If patio installation

requires that a chimney passes through a roof or room above, be sure to comply with all local building codes.

Room Above

Step 9. Cut or frame a hole through the outside

of the enclosure for the installation of the duct inlet hood per the instructions on Page 8.

INSTALLING THE CHIMNEY SYSTEM

Step 1. Before continuing, check the operation

of the damper, as described on Page 5, (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.

In new construction, to determine chimney center line, use plumb line from roof or ceiling above ﬁ replace to center of ﬂ ue collar on ﬁ replace.

For remodeling, plumb to center of ﬂ ue collar from ceiling above, drive nail through ceiling from below to mark position, then mark and cut to passage from above ceiling (around nail) (see Figure 28). Then plumb from ceiling or roof level directly above hole which has just been completed.

Step 4. Note: Chimney sections are constructed

with a unique locking tab design, which ensures an immediate, tight assembly between sections. Plan your chimney requirements carefully before assembly as chimney is difﬁ cult to disassemble after installation. If disassembled, the tabs might become damaged. Be certain tabs are properly formed to ensure locking tabs engage properly.

The Security Chimney's FTF8 chimney system is a two piece chimney, which snap together from the ﬁ replace up. Start with the inner ﬂ ue section with the lanced end up, snap lock it in to the matching collar on top of the ﬁ replace. At all subsequent joints, the upper ﬂ ue section ﬁ ts into the preceding ﬂ ue section. Each piece snaps together by means of locking tabs (9 locking tabs per joint). Check each piece by pulling up slightly from the top to ensure proper engagement before installing the next section. If the ﬂ ue has been installed correctly, it will not separate when you test it. Also, the inner ﬂ ue joint where each section is joined should be tight and ﬂ at without gaps (Figure 34).

Note: Assemble one component of chimney at a time (inner section ﬁ rst, then outer section last) before proceeding with the next complete section.

Continue to assemble the chimney up through framed opening. Assemble just enough to penetrate the roof ﬂ ashing openings (Figure

36). Always maintain 1"* minimum air space to insulation and construction materials. 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.

Step 5. The height of vertical chimney pipe supported only by the ﬁ replace must not exceed 30'. Chimney heights above 30' must be supported by a Model FTF8-S4 stabilizer installed at 30' intervals.

Note: The Model FTF8-S4 adds 3" net effective height to the total chimney system.

Install the Model FTF8-S4 stabilizer by ﬁ tting inner section down into respective section of proceeding ﬂ ue 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 (see Figure 37).

*Notes:

• 2" clearance to combustibles required in Canada.

NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.

Roof Ridge

FTF8-S4 Stabilizer

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 ﬂ ashing based on pitch of roof. Use chart below for selection:

Roof Pitch Model

Flat to 6/12

6/12 to 12/12

Next, slide roof ﬂ ashing over extended chimney section that previously has been installed above the roof opening in Step 4. FTF8 ﬂ ashings require ﬂ ashing spacers. Slide ﬂ ashing all the way down until the ﬂ ashing base rests ﬂ at on the roof (Figure 38). Again, check the vertical position of the chimney and the 1"* minimum air space to combustibles.

F8F6

Figure 39

Step 8. The standard Security FTF8 roof ﬂ ashing assemblies include a storm collar. Slide the storm collar over outer chimney, rest on ﬂ ashing spacers and align with top surface of ﬂ ashing. 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 40). Check all joints very carefully to ensure no water intrusion can take place.

Step 7. Secure ﬂ ashing by nailing along the perimeter into roof using 8d nails. If shingled roof, slide upper end and sides of roof ﬂ ashing under shingles (trim if necessary), seal the top and both sides of the ﬂ ashing to the roof with roof caulking. Cover nail heads with roof caulking (Figure 39).

*Note: 2" clearance to combustibles required in Canada.

Figure 40

Step 9. Security Chimneys locking bands, Model FLB, may be required if the chimney extends too high above the roof ﬂ ashing. As a general rule, if the chimney extends more than 6' above the roof ﬂ ashing, 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 40).

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 (see Figure 41). Guy wires are not supplied by the manufacturer.

3. Center outer locking section over outer ﬂ ue pipe. Push down until locking tabs are ﬁ rmly engaged.

4. Pull up slightly on CTD to ensure locking joint has ﬁ rmly engaged.

Using a FTF8-CTD, FTF8-CTDT (or CTDTM) Chase Termination:

Refer to specific installation instructions (750,014M) included with the FTF8-CTDT (or 750,205M for FTF8-CTDTM) chase termination for clearance and installation details.

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

1. Determine total vertical height of the ﬁ replace installation. This dimension is the distance from the surface the ﬁ replace 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 ﬁ restop spacers, stabilizers, roof ﬂ ashing, etc.

3. The effective heights of the components are:

Note: It is recommended that all exterior exposed metal ﬁ replace components; such as terminations, ﬂ ashings, storm collars and/or ﬂ ue 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 speciﬁ ed 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 ﬁ replace not draft properly (refer to Figure 43).

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 ﬂ ue center to ﬂ ue 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 44).

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 ﬂ ue into the other.

FTF8 CHIMNEY COMPONENT CALCULATIONS

* Required for every 30' of vertical chimney and/or 10' of offset chimney.

4. Determine amount of chimney height required by subtracting total combined height of all preselected components (ﬁ replace 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 Chimneys 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 ﬁ rst component used off the top of the ﬁ replace ﬂ ue collar.

NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.

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 45). 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 46). Example: If C cannot exceed 10'.

= 10' then C2

If an offset exceeds 6' in length, each chimney joint beyond the ﬁ rst 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 47).

A 1/8" diameter hole must be drilled in the chimney joint using a 1/8 " diameter drill. The hole should be drilled in center of joint overlap (Figure 48). Be sure to drill only through the outer chimney casting. Do not puncture the inner ﬂ ue.

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 ﬂ ue 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 FTF8-30 offset elbow in place of a FTF8-E30 return elbow.

OFFSET CALCULATIONS

Step 1. Use the Offset Chart (Table 4) to deter-

mine 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.

Step 3. Use Elevation Chart as job estimator only. Add necessary ﬁ restop spacers and stabilizers as required. Firestop spacers must be used as shown in Figures 31 & 32 and stabilizers as shown in Figure 37.

Gas Line Connection

Install a 1/2" gas supply line through ﬁ replace wall for connection to a decorative gas appliance inside the ﬁ rebox. Outside, the gas supply line connects to a gas shut-off valve recessed ﬂ ush into the wall or ﬂ oor. The valve should be controlled by a removable valve key for safety.

Always plumb gas line installation per local codes. Check all connections with a gas leak detection solution for leaks (which will bubble if present). Never test any gas line connection with a match or open ﬂ ame.

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 ﬁ replaces, 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.

Table 4

Vent Free Appliances

This unit has been tested and approved to ANSI/IAS/AGA Z21.11.2 for use with unvented gas appliances for INDOOR INSTALLATIONS ONLY and complies with the standard for Factory-Built ﬁ replaces, UL 127, when installed with unvented gas log sets.

Special instructions with regards to mantel installations must be taken into consideration when installing such appliances.

The unit has been tested for use with any unvented log sets having a maximum rating of 26,000 BTU in Indoor installations only. The minimum mantel conﬁ guration for these log sets are outlined in Figure 52.

Log sets with 40,000 BTU may be installed provided that no combustible mantel projections are placed lower than 18 inches from the ﬁ replace opening.

These ﬁ replaces have been marked with a maximum rating of 26,000 BTU to assure that homeowners do not exceed the allowable limits for all allowed installations of mantels. That limit may be increased to 40,000 BTU, provided that the mantel installed complies with the 18-inch limitation and a copy of these instructions are available.

IMPORTANT

Allow minimum 1"* chimney air space to combustible framing members throughout vertical or offset chimney installation.

ATTENTION

Permettez 1 minimal” * l’espace aérien de cheminée aux membres encadrants combustibles partout dans vertical ou à l’installation de cheminée de rejeton.

WARNING

Unvented Gas Log Sets are not approved for use with ﬁ replaces installed outdoors. The materials and components will deteriorate prematurely if installed outside. Refer to the log manufacturer’s literature for limitations and exceptions.

AVERTISSEMENT

Les ensembles de bûches à gaz sans conduit d’évacuation ne sont pas approuves pour l’usage avec des foyers installes a l’exterieur. Les materiaux et les composantes se deterioreront prematurement si installees a l’exterieur. Referezvous a la litterature du fabricant des buches pour les limites et les exceptions.

CAUTION

Plumbing connections should only be performed by a qualiﬁ ed, licensed plumber. Main gas supply must be off when plumbing gas line to ﬁ replace or performing service.

ATTENTION

Les raccordements de tuyauterie devraient seulement etre effectues par un plombier qualiﬁ e et autorise. La valve d’alimentation de gaz principale doit etre fermee lors de l’installation ou de l’entretien de ce foyer.

If you’re installing a gas line, connect it before the ﬁ replace is framed and enclosed in the ﬁ nished 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 INSIDE 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 sufﬁ cient diameter for the gas line to ﬁ t 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, INTERIOR AND EXTERIOR OF FIREPLACE, TO SEAL.

Glass Doors

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

CAUTION

Certain glass doors overlap the black metal facing of the ﬁ replace. IF the ﬁ replace has been faced with noncombustible materials, there might not be sufﬁ cient clearance to install the glass doors of your choice. Ensure adequate clearance is maintained at all times so as not to interfere with the installation and operation of glass doors.

*Note: In Canada, a 2” clearance to combustibles is required.

* Note : Au Canada, po. de jeu 2 aux combustibles est exigé.

NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.

ATTENTION

Certaines portes de verre recouvrent le revêtement noir en métal du foyer. SI la façade du foyer a été recouverte avec des matériaux non-combustibles, il se pourrait qu’il n’y ait pas sufﬁ sament de dégagement pour installer les portes de verre de votre choix. Assurez d’avoir un dégagmet sufﬁ sant à tout moment aﬁ n de ne pas interférer avec l’installation et l’opération des portes de verre.

COLD CLIMATE INSULATION

If you live in a cold climate, it is especially important to seal all cracks around the ﬁ replace 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 ﬁ replace to avoid cold air intrusion. Use noncombustible caulking material only on ﬁ replace 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 ﬁ replace or against chimney sections. If gas logs are installed, the gas line holes and other openings should be caulked with high temperature caulk or stuffed with unfaced ﬁ berglass insulation.

Note: A 1"* air space must be preserved for all insulation and construction 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 ﬂ oor if the ﬂ oor is above ground level. Do not place insulation directly against the ﬁ replace or chimney system.

FIREPLACE FINISHES

Mantels and Trim

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

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

These ﬁ replaces may sit directly on a combustible surface. A 1"* air space is required between insulation and building materials and the chimney. A 1" air space is required between combustible framing and ﬁ replace outer wrapper.

In Canada, the minimum height for a combustible mantel is 18" (457 mm) above the ﬁ replace opening. Figure 51 shows typical Canadian installations. Combustible mantels and trim may be installed 12" above the ﬁ replace opening as per NFPA 211-latest edition and Figure 52. 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.

*Note: 2" clearance to combustibles required in Canada.

Note: Do not place any combustible materials on the ﬁ replace face.

Hearth Extensions and Wall Shields

A hearth extension must be installed with all ﬁ replaces. It is to protect the combustible ﬂ oor in front of the ﬁ replace from both radiant heat and sparks. The hearth extension must extend 8" beyond both sides of the ﬁ replace opening and 16" beyond the front (see Figure

53). 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 that equals or exceeds r = 1.19 HR °F FT IN. With these values, determine the minimum thickness/material required using the formula and Table 5 on Page 21.

Note: Any noncombustible material having a thickness of 1" whose k value is less than .84 or whose r value is more than 1.19 is acceptable.

If the ﬁ replace is installed on a combustible ﬂ oor, use the metal safety strips (provided) on the ﬂ oor extending half under the ﬁ replace and half under the hearth extension (refer to Figures 21 & 22).

A wall shield is required where a continuous perpendicular side wall is within 12" of the ﬁ replace opening (Figure 53). Use a 24" W x 30" H x 1/2" wall shield constructed of a durable, noncombustible material having an equal or better (lower k value) insulating value than k = .54 BTU IN/FT perpendicular side wall be located closer than 7" from the ﬁ replace opening.

Methods of Determining Hearth Extension and Wall Shield Equivalents - To determine the thickness required for the alternate

material when either the "k" value or "r" value is known, use either the k formula or r formula.

Example: If Micore 160 is to be used for the hearth extension ﬁ replace,

how thick must this material be?

= k value per inch of alternate material

rM = r value per inch of alternate material

TM = minimum thickness required for alternate material T

= standard thickness of the alternate material

= k value per inch of listed material

rL = r value per inch of listed material

= minimum thickness of listed material

Note: An asterix "*" indicates, it is a value taken from Table 5. Using the k formula:

Minimum k-value (per Inch) of Speciﬁ ed min. thickness of = alternate material (k alternate k-value (per inch) of listed material (T

(inches) = kM x TL

) of listed material (kL) material (TL)

) x thickness

TM (inches) = *.35 x 1" *.84

.416 (inches)= .416 x 1"

Answer - The minimum required thickness of the Micore 160 is .417," therefore round up to nearest standard thickness available which is 1/2."

Calculating Minimum Thickness if Multiple Materials are Used

WARNING

At times it is important to know what combination of materials are acceptable for use as ﬂ oor 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 ﬂ oor protector used must be equal to or greater than:

“R” =

x TL = 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 ﬂ oor 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:

“R”M = rM x TS = 0.20 x 3 1/2" = .70

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

“R”M = rM x TS = 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:

“R”M = rM x TS = 0.05 x 3/4" = .038

“R”M = rM x TS = 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 s

expanded explanation on calculating “R values” when multiple materials are used.

The crack between the ﬁ replace and the hearth extension must be sealed with a noncombustible material.

AVERTISSEMENT

La fente entre le foyer et l’extension d’âtre doit être scellée avec un matériel noncombustible.

WARNING

When installing hearth extension in front of a non-circulating ﬁ replace model, the ﬁ replace must be raised if height of hearth extension exceeds 7" above the bottom of ﬁ replace (Figure 54).

When installing the hearth extension be careful not to block the heat-circulating air inlet grill on circulating models.

AVERTISSEMENT

En installant la prolongation de foyer devant un modèle decirculation de cheminée, la cheminée doit être augmentée si la taille de la prolongation de foyer excède 7”(pouces) au-dessus du fond de la cheminée

(Figure 54).

En installant l’extension d’âtre faites attention à ne pas bloquer la grille d’entrée d’air sur les modèles à circulation d’air.

FINISH TO YOUR TASTE

There are a wide variety of “ﬁ nished looks” for these ﬁ replaces, 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 ﬁ rebox 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 ﬁ nished wall.

Combustible materials may project beyond the sides of the ﬁ replace opening as long as they are kept within the shaded areas illustrated in

Figure 55.
