SAFETY RULES:

WARNING

To avoid the risk of damaging ﬁ replace materials and increasing the risk of ﬁ re, do not use the ﬁ replace to cook or warm food.

1. Before starting your ﬁ replace installation,

read these installation instructions carefully to be sure you understand them completely and in entirety. Failure to follow them could cause a ﬁ replace 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 ﬁ replaces must be installed with

Security Chimneys FTF8 (8" inside diameter) Chimney System only. These systems are intended for use in any application where a traditional masonry type ﬁ replace would apply. The chimney system must always vent to the outside of the building.

4. To ensure a safe ﬁ replace system and to

prevent the build-up of soot and creosote, inspect and clean the ﬁ replace and chimney prior to use and periodically during the heating season.

5. Burn approved fuels only as deﬁ ned in the

Homeowner's Care and Operation Manual.

6. DO NOT use charcoal or coal under any

circumstances.

7. NEVER use gasoline, gasoline-type lantern

fuel, kerosene, charcoal lighter ﬂ uid, or similar liquids to start or “freshen up” a ﬁ re in this ﬁ replace. Keep any ﬂ ammable liquids a safe distance from the ﬁ replace.

8. NEVER leave children unattended when there

is a ﬁ re burning in the ﬁ replace.

9. Always keep ﬂ ue damper open when heat is

present in the ﬁ replace.

10.Before servicing, allow the ﬁ replace to cool.

Always shut off any electricity or gas to the ﬁ replace while working on it. This will prevent any possible electrical shock or burns.

11.This ﬁ replace is not intended to heat an

entire home or be used as a primary heat source. It is designed to provide aesthetics and limited 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 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 combustion air kit (provided) 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 ﬁ replace.

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 the manufacturer of this Superior appliance for use with this ﬁ replace. All gas log sets must be operated with the damper clamped open.

WARNING

This ﬁ replace has not been tested with an unvented gas log set. To reduce risk of ﬁ re or injury, do not install an unvented gas log set into this ﬁ replace.

15."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.

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. These items should be inspected by your distributor or qualiﬁ ed factory representative to ensure safe condition. When in doubt, consult your distributor.

INTRODUCTION General Information

These ﬁ replaces are conventional heat circulating appliances with standard grates, outside combustion air kit and standard decorative glass doors. The BCD36MH model is ﬁ tted with a blower and is available as an option for model BC36MH.

The grate included properly positions the ﬁ re and limits the amount of fuel. IF A REPLACEMENT

GRATE IS NEEDED REPLACE THE GRATE WITH MODEL 87L20

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 Warnock Hersey (Report No. J99025865A) to U.L. standard 127. These units are intended for installation in manufactured homes. These units may also be installed in buildings of conventional construction including commercial, providing all instructions provided herein are strictly adhered to.

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.

TYPICAL INSTALLATION

ONLY.

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 ﬁ re hazard and void the limited warranty.

WARNING

Do not pack or ﬁ ll required air spaces with insulation or other material. No material is allowed in these areas. Secure the airspace around the chimney with the ﬁ restop/thimble before completing the installation. Maintain 1" clearance between chimney and thimble.

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.

When complete these ﬁ replace systems consists of four basic “sub-systems”:

1. The Fireplace

2. The Chimney and Termination

3. Glass Doors

4. Combustion Air Kit

The minimum installed height of the completed ﬁ replace system is 10' 6". The maximum height is 40' 0". See the Chimney Height section on Page 3 for more information.

The ﬁ replace 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 ﬁ re hazard.

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

CHIMNEY SYSTEM

These ﬁ replaces are designed and code listed for use with Security Chimneys FTF8 chimney system only. Always use Security Chimneys FTF8 chimney components with these ﬁ replaces. Do not modify or alter these components as this may cause a potential serious hazard and void the Warranty.

Chimney Enclosure

Construct a box-like framed structure to enclose the ﬁ replace and chimney within the conﬁ nes of the manufactured home, not necessarily above the roof line.

As with all chimney installations, avoid overhead obstructions such as trees, power lines, etc. The chimney/ﬁ replace enclosure should be constructed and insulated just like any outside wall. In a cold climate, we recommend the base of the chimney/ﬁ replace enclosure should also be insulated between the solid continuous ﬂ oor beneath the ﬁ replace and the chase bottom. Insulation in a cold climate installation is not required for safety.

Note: Local codes may not require ﬁ restopping at the ceiling levels for outside chimney enclosure 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.

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.

Figure 4

WARNING

This fireplace and chimney system is not approved for use in a bedroom or any room used for sleeping.

Carefully consider the position of the ﬁ replace 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 ﬁ replace condition if the house is tightly insulated.

When locating the ﬁ replace, consideration must be given to combustibles and ﬁ nal ﬁ nishing. See Figure 5 and conﬁ ne the ﬁ nal location of combustible ﬁ nish materials to the "Safe Zone".

DO NOT permanently place furniture or other items such as decorative pillows within 60" of the ﬁ replace front face.

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. Install the chimney system.

3. Connect house wiring to the fireplace

for blower (blower is optional for model BC36MH).

4. Install the 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/ certiﬁ ed tradesman).

6. Complete the installation, ﬁ nish wall mate-

rial, surround and hearth extension to your individual taste.

Study the three dimensional illustration (Figure

1) 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 so 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 weights for the ﬁ replace may be found on Page 7.

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.

CAUTION

Do not block the heat-circulating air inlet and outlet ports. Doing so may result in a potential ﬁ re hazard.

CAUTION

The structural integrity of the manufactured home ﬂ oor, wall, ceiling and roof must be maintained.

The ﬁ restop thimble supplied with the unit must be used on a manufactured home installation. The ﬁ restop thimble must extend completely though the roof cavity to the outermost plane of the roof (See Figures 16, 17 and 18). Maintain 1" clearance between the thimble and the chimney.

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.

CLEARANCES

Minimum clearance to combustibles for the appliance is as follows: sides and back - 1" (25 mm), ﬂ oor - 0" (0 mm), adjacent wall - 12" (305 mm), ceiling - 37-1/2" (953 mm).

INSTALLING THE FIREPLACE

IMPORTANT: Plated polished brass glass doors may have a plastic covering over all brass pieces for protection during shipping and handling. The plastic covering should be removed after installation of the ﬁ replace before its use. Under the plastic covering is a protective lacquer coating which should not be removed. In some instances, if it is removed, irreversible damage to the brass ﬁ nish could occur.

Step 1. Slide the ﬁ replace into prepared framing

or position ﬁ replace in its ﬁ nal position and frame later.

The ﬁ replace may not be recessed into

a combustible ﬂ oor. Maintain the ﬂ oor to hearth clearance established by the ﬁ replace lower front face.

Step 2. Insert the provided metal safety strips,

beneath the ﬁ replace as illustrated (Figures 6 through 9). The safety strips should overlap 1/2" for continual coverage of the ﬂ oor.

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

Step 4. Fireplace should be secured to side

framing members using the full length nailing tabs at the top and bottom of the ﬁ replace front face. Use screws, 8d nails or equivalent fasteners (Figure

13). This manufactured home model is also provided with ﬂ oor brackets used to secure the ﬁ replace to the ﬂ oor to prevent shifting in transit.

Note: The use of ﬂ oor brackets are optional. They are included (unbent) inside the Combustion Air Kit package, located inside the ﬁ rebox. Refer to Figure 8 for suggested bracket placement.

Reference Figures 10 and 11 and their charts for framing dimensions at Ceilings and Roofs.

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) (Figure 14). Then plumb from ceiling or roof level directly above hole which has just been completed.

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 ﬁ rebox wrapper to the framing at the closest point of contact, directly adjacent to the ﬂ ange.

INSTALLING THE CHIMNEY SYSTEM

Step 1. Before continuing, check the operation

of the damper, as described on Page 4, (refer to Figure 2).

Step 2. Using standard construction fram-

ing 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 1" chimney air space to framing members throughout chimney installation. A minimum 1" air space must be maintained from all insulation and building materials extending for any continuous length surrounding the chimney.

Figure 14

Step 3. Position appropriate thimble/ﬁ restop

spacer combination at ceiling and nail temporarily with two (2) 8d nails or equivalent fasteners (see Figures 16, 17 and 18). Use one fastener on opposite sides to hold thimble/ﬁ restop spacer combination in position. Nail permanently, using at least two (2) more fasteners, after chimney sections have been assembled through the thimble/ﬁ restop spacer combination and after any necessary adjustments have been made. Firestop spacer must be secured by at least four (4) fasteners when completely installed.

Note: 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 thimble must be installed on the bottom side of ceiling joist (Figure 15).

NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.

Figure 16

Firestop Thimble

Ensure the thimble penetrates the roof opening. The thimble must extend completely through the ceiling or roof cavity to the outermost plane of the roof. Note: Thimble extensions (F8-TE26) are available from your dealer for constructions in which the distance between the outside of the roof and the inside of the ceiling exceeds 13". The thimbles and their extensions provide for zero clearances to combustibles and must be used at the ceiling/roof in manufactured homes (Figures 17 and 18).

Step 4. Note: Chimney sections are con-

structed 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 Chimneys 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 19).

Thimble Cathedral Ceiling

Use Adjustable Thimble FM8-AT1 For All Ceiling Piches, From Flat To 3/12 Pitch.

Outer pipe section installs in just the opposite way; the lanced end goes down and each new section goes OVER the outside of the previous section installed (Figure 20).

Locking Tab s (Lances)

Figure 20

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

21). Maintain 1" minimum air space to insula- tion and building 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 21

Security's chimney sections do not need to be screwed together. Additional reinforcement is not necessary except in certain offset conditions (refer to Page 13, Figure 35).

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 (Figure 22).

FTF8-S4 Stabilizer

Figure 22

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 FTF8

Flat to 6/12 F8-F6

6/12 to 12/12 F8-F12

Table 2

Next, slide roof ﬂ ashing over extended chimney section that previously has been installed above the roof opening in Step 4. Slide ﬂ ashing all the way down until the ﬂ ashing base rests ﬂ at on the roof (Figure 23). Again, check the vertical position of the chimney and the minimum air space to combustibles.

FTF8 Chimney

Figure 19

Step 5. The height of vertical chimney pipe sup-

ported 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.

Step 7. Secure ﬂ ashing by nailing along the

perimeter into roof using 8d nails or equivalent fasteners. 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 fastener heads with roof caulking

(Figure 24).

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 26). Guy wires are not supplied by the manufacturer.

4. Pull up slightly on CTD to ensure locking

joint has ﬁ rmly engaged.

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.

Step 8. The standard Security Chimneys 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 25). Check all joints very carefully to ensure no water intrusion can take place.

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 (Figure 28).

2' (610mm) Min.

Step 9. FTF 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 25).

FTF8 CHIMNEY COMPONENT CALCULATIONS

The minimum installed height of the completed ﬁ replace system is 10' 6". The maximum height is 40' 0" when the chimney is exposed.

Air Space

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'.

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 thimbles, extensions, roof ﬂ ashing, etc.

3. The effective heights of the components are:

The Fireplace = 37” FTF8-12 = 10-1/4” FTF8-18 = 16-1/4” FTF8-24 = 22-1/4” FTF8-36 = 34-1/4” FTF8-48 = 46-1/4” FTF8-CTD Termination = 6”

4 Determine amoun of chimney height required

by subtracting total combined height of all pre-selected 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

Chimney 30° Offset through Floor or Ceiling

It may be necessary to assemble the chimney at 30° when passing through the ﬂ oor or ceiling area. Use the F8FS30-2 ﬁ restop spacer as shown in Figure 29. Support the chimney at ﬂ oor or ceiling penetration with a FTF8 stabilizer if distance of chimney below ceiling is 10' or more. Maintain 1" minimum air space to combustibles from chimney sections. The chimney must pass vertically through the attic space.

Figure 29

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 ﬁ rst component used off the top of the ﬁ replace ﬂ ue 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 (see Figure 30). 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' (see Figure 31). Example: If C C2 cannot exceed 10'.

= 10' then

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 (see Figure 33).

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 33). Be sure to drill only through the outer chimney casting. Do not puncture the inner ﬂ ue.

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 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.

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 Figure 29 and stabilizers as shown in Figure 22.

INSTALLING OFFSETS

First, review the Offset Elevation Chart and Figure 34 for reference.

Step 1. Determine the offset distance where

chimney is to pass through the ﬁ rst ceiling-dimension “A.” To ﬁ nd this point on your ceiling, ﬁ rst determine the center point for a vertical chimney following the instructions for vertical installation.

Measure height to the ceiling from

the top of ﬁ replace-dimension “B.” Use the appropriate Offset Elevation Chart to ﬁ nd 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 In-

stallation 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.

Notes:

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

• 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.

OPTIONAL EQUIPMENT CONSIDERATIONS

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 using a gas leak test solution (also referred to as bubble leak solution). Note: Using a soapy water solution (50% dish soap, 50% water) is an effective leak test solution but it is not recommended, because the soap residue that is left on the pipes/ﬁ ttings can result in corrosion over time. 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.

WARNING

This ﬁ replace has not been tested with an unvented gas log set. To reduce risk of ﬁ re or injury, do not install an unvented gas log set into this ﬁ replace.

NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.

CAUTION

When using the decorative gas appliance, the ﬁ replace damper must be set in the fully open position.

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.

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 KNOCK-

OUT 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 ﬁ replace, to seal.

COLD CLIMATE INSULATION

If you live in a cold climate, it is especially important to seal all cracks around the ﬁ replace and wherever cold air could enter the room with noncombustible material. Surround material 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 directly against the chimney sections.

Note: 1" (25 mm) air space must be preserved for all materials extending for any continuous length adjacent to the chimney.

Page 16

Note: A 1" 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 ﬂ oor if the ﬂ oor is above ground level. Do not place insulation directly against the ﬁ replace or chimney system.

Glass Doors

Glass doors have been installed on these ﬁ replaces as standard equipment. Shipping and transit may have moved them out of alignment.

The doors are properly adjusted when the top door trim is in a straight, level line and the gap between the doors is even at the top and bottom. If adjustments are required, grasp the door handle and loosen the lower door pivot pin using a 3/8” open end wrench*. Slide the door panel on the hinge pin until the gap between the upper door trim and upper frame is even. Retighten the lower door pivot pin*. Repeat this procedure for the opposite door if needed (Figure 40).

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 materials of suitable grade and size as dictated by the prevailing constructions standards for the structure in which the ﬁ replace system is to be located within.

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 ﬁ t around the spacers.

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

Combustible mantels and trim may be installed 12" above the ﬁ replace opening as per NFPA 211-latest edition. and Figure 41. 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.

Hearth Extensions and Wall Shields

A hearth extension must be installed with all ﬁ replaces. Its purpose is twofold. It protects a combustible ﬂ oor in front of the ﬁ replace from both radiant heat and sparks and it distinguishes the prescribed hearth extension area from other non-protected surfaces.

The hearth extension must extend 16" beyond the front and 8" beyond both sides of the ﬁ replace opening. 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 resistance that equals or exceeds r=1.19 HR

°F FT

/BTU IN. A minimum 3/8" (10 mm) thick noncombustible material is all that is required over a noncombustible or slab ﬂ oor.

If there is a continuous perpendicular side wall closer than 12" (305 mm) from the ﬁ replace opening, it must be protected with a 24" x 30"x 1/2" (610 mm x 762 mm x 13 mm) wall

shield (see Figure 42) constructed of a durable, noncombustible material having an equal or better (lower k value) insulating value than k = .84 BTU IN/FT

HR °F. A continuous protected side wall can not be closer than 7" (178 mm) from the side of the ﬁ replace opening.

Secure the hearth extension to the ﬂ oor to prevent possible shifting.

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 6 and 7).

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 (kM) x thickness alternate k-value (per inch) of listed material (T

(inches) = kM x TL

) of listed material (kL) material (TL)

*.84

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."

Using the r formula:

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

** If the hearth extension material(s) that is intended to be used is NOT listed on Table 5, the material can still be used if the material(s) is noncombustible. However, the manufacturer of the material must provide either the listed k-value 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 speciﬁ ed in the NFI Certiﬁ cation Manuals).

Note: Also see NFI (National Fireplace Institute) Certiﬁ cation Manuals showing other exceptable caluculation methods and acceptable alternate materials which can be used.

Calculating Minimum Thickness if Multiple Materials are Used

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:

brick

“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:

mortar

“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:

marble

“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

mortar

ee NFI Certiﬁ cation Manuals for expanded explanation on calculating “R values” when multiple materials are used.

WARNING

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

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 3-5/16" above the bottom of ﬁ replace (Figure 43).

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

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 44.
