2. Locating Fireplace & Chimney

Location of the fireplace and chimney will affect perfor mance.

• Install within the warm airspace enclosed by the building envelope. This helps to produce more draft, especially during lighting and die-down of the fire.

• Penetrate the highest part of the roof. This minimizes the effects of wind loading.

• Locate termination cap away from trees, adjacent structures, uneven roof lines and other obstructions.

• Minimize the use of chimney offsets.

• Consider the fireplace location relative to floor and ceiling and attic joists.

• Take into consideration the termination requirements in

Sections 5 and 6.

• Install the outside air kit and CAK (chimney air kit) with the intake facing prevailing winds during the heating season.

• Ensure adequate outdoor air for all combustion appliances and exhaust equipment.

• Ensure furnace and air conditioning return vents are not located in the immediate vicinity of the fireplace.

• Avoid installing the fireplace near doors, walkways or small isolated spaces.

• Recessed lighting should be a “sealed can” design.

• Attic hatches weather stripped or sealed.

• Attic mounted duct work and air handler joints and seams taped or sealed.

C. Construct the Chase

WARNING! Risk of Fire! DO NOT seal area between fire stop opening and chimney pipe except where they enter the attic or leave the warm air envelope of the home (use

600° F sealant).

WARNING! Risk of Fire! You must maintain a minimum 2 in. (51 mm) air space clearance to insulation and framing surrounding the chimney system.

A chase is a vertical boxlike structure built to enclose the fireplace and/or its vent system. Vertical chimneys that run on the outside of a building must be installed inside a chase. See Figure 3.4.

Construction of the chase may vary with the type of build ing. Local building codes MUST be followed.

Hearth & Home Technologies recommends:

- The inside surfaces be drywalled and taped (or the use of an equivalent method) for maximum air tightness to the false ceiling.

- In cold climates, the walls of the chase should be insulated to the level of the false ceiling as shown in

Figure 3.3. This will help reduce heat loss from the home around the fireplace.

- Holes and other openings should be caulked with high temperature caulk or stuffed with unfaced fiber glass insulation.

• Requirements for constructing the chase:

- A firestop spacer and attic insulation shield should be installed at the false ceiling.

- The chase must be properly blocked to prevent blown insulation or other combustibles from entering and making contact with fireplace or chimney.

- The chase top must be constructed of noncombustible material.

• The chase is constructed using framing materials much the same as the walls in your home. A variety of siding materials may be used including brick, stone, veneer brick, or standard siding materials.

• In constructing the chase, several factors must be considered:

- Maintain a 2 in. (51 mm) air space around the chimney.

- The chase top must be constructed of noncombustible material.

- In cold climates, a firestop spacer and attic insulation shield should be installed in an insulated false ceiling at the 8 ft. (2438 mm) level above the fireplace assembly. This reduces heat loss through the chase.

- In cold climates, the walls of the chase should be insulated to the level of the false ceiling as shown in

Figure 3.4. This will help reduce heat loss from the home around the fireplace.

D. Frame the Fireplace

WARNING! Risk of Fire! Comply with all minimum clear ances specified.

• A minimum 1/2 in. (13 mm) air clearance must be maintained at the back and 1 in. (25 mm) to the sides of the fireplace assembly.

• Chimney sections at any level require a 2 in. (51 mm) minimum air space clearance between the framing and chimney section.

WARNING! Risk of Fire! You must comply with all mini mum air space clearances to combustibles. DO NOT pack required air spaces with insulation or other materials.


NOTICE: Hearth extension design must be determined before installation of fireplace.

If the fireplace is placed on the floor, the maximum height of a finished raised hearth (constructed of non-combustible material) is 5-3/4 in. (147 mm). If a higher raised hearth is preferred, the fireplace must be placed on a platform.

NOTICE: Wiring for fans must be done before framed enclosure is completed. If using the Heat-Zone-WD-C

Kit, it also must be installed before enclosure is complete.

Standoffs are attached to the fireplace.

NOTE: Before framing up the chase, consider where and how the chimney will run. If there are obstacles that might be in the way, it maybe necessary to make the chase larger than shown to allow for offsets to be used.

Refer to offset chart on page 24.

The unit can be positioned with the standoffs touching combustible walls or framing but DO NOT pack insulation or other materials in the air space between the fireplace and wall.

Figure 3.5 shows a typical framing (using 2 x 4 lumber) of the fireplace, assuming combustible materials are used. All required clearances to combustibles around the fireplace must be adhered to. See Figure 3.2. (No recess above fire place.)

14 1/2 in. (368 mm) for

CAUTION! Risk of Cuts/Abrasions. Wear protective gloves and safety glasses during installation. Sheet metal edges are sharp.

NOTE: Before framing up the chase, consider where and how the chimney will run. If there are obstacles that might be in the way, it may be necessary to make the chase larger than shown to allow for offsets to be used. Refer to offset chart on page 24 if needed.

E. Secure and Level the Fireplace

This fireplace may be placed on either a combustible or noncombustible continuous flat surface. Follow the instruc tions for framing in Section 3. Slide the fireplace into posi tion. Be sure to provide the minimum 1 in. air clearance at the sides and 1/2 in. at the back of the fireplace.

The fireplace should be positioned so the face of the noncombustible material on the fireplace will be flush with the face of the drywall on the walls. See Figure 3.6.

Level the fireplace and shim as necessary. Secure the fire place (using the pallet mounting brackets located on either side of the fireplace) to the sub floor.

2 x 4s must be used for the header and framing above the header to maintain pipe clearances.

H. Non-Combustible Facing Board

(Provided)


Follow these instructions exactly.

Facing materials must be installed properly to prevent fire.

No materials may be substituted without authorization by

Hearth & Home Technologies.

TOOLS NEEDED: Powered drill with #2 Phillips head bit; caulking gun.

Only non-combustible materials (supplied with fireplace) may be used to cover the metal fireplace front.

All boards are pre-drilled for your convenience.

Boards MUST be attached in the following order: bottom, sides, and then the top, red-painted side out.

The top and bottom board should each have a hang tag attached. Leave them attached for referral for the finishing operation.

• Attach the bottom board to the bottom of the fireplace outer shell with enclosed screws, ensuring the board is centered. DO NOT remove hang tags . Attach the side pieces to the outer shell and framing members. See

Figure 3.11.

• Center and attach the top board to the outer shell and framing members.

DO NOT remove hang tags.

1/8 in. of the facing material may be visible after finishing materials are applied. This 1/8 in. must be painted or the red will show.

I. Outside Air Kit

An outside air kit must be used for combustion. Hearth &

Home Technologies recommends you utilize the shortest duct run and install a P-Trap (see Figure 3.18) to optimize the performance of the outside air kit with a maximum length of 40 ft. The outside air inlet hood should be posi tioned in a manner that will not allow snow, leaves, etc. to block the inlet. In some installations the air duct may need to be run vertically. In such an installation, a 3 ft (914 mm) height difference must be maintained from the top of the uppermost chimney section to the outside air inlet hood.

Refer to Figures 3.19 and 3.20 when placing the outside air inlet hood.

NOTE: The minimum cross-sectional area of the inlet hood is 17.5 square inches.

The outside air kit comes installed on the right hand side of the fireplace but may be moved to the other side by fol lowing these steps:

1. Remove outside air collar (Figure 3.12) and the outside air cover plate (Figure 3.13).

2. Install the cover plate on the right side and the collar on the left side.

3. Open and remove the lower access panel.

4. Remove the two (2) outer screws (Figure 3.16) to allow the outside air box to be removed.

5. Pull the outside air box straight out. See Figure 3.17.

6. On the left side, remove the cover plate two (2) screws.

See Figure 3.14.

AFTER finishing materials are applied. This 1/8 in. must be painted or the red will show.

7. Install the cover plate on the right side where the outside air box was and install the outside air box in through the hole on the left side where the cover plate was.

►

• Cut a 6-1/2 in. (165 mm) hole in outside wall to accommodate air piping.

• Use 6 in. (152 mm) UL181 Class1 or Class 0 rigid or flexible ducting (not supplied) to directly connect outside air to fireplace intake. Insulate the pipe to prevent frost condensation. See Figure 3.18.

• Insulating the pipe isn’t required but will help prevent frost condensation.

• Use the supplied outside air inlet hood.

• Seal between the wall and the pipe with silicone to prevent moisture penetration and air leaks.

• Seal between the outside air inlet hood and the house with silicone to prevent air infiltration.

CAUTION! Risk of Fire or Asphyxiation! DO NOT draw outside combustion air from wall, floor or ceiling cavity, or enclosed spaces such as an attic or garage.

• DO NOT place outside air inlet hood close to exhaust vents or chimneys. Fumes or odor could be drawn into the room through the fireplace.

• Locate outside air inlet hood to prevent blockage from leaves, snow/ice, or other debris. Blockages could cause combustion air starvation.


CAUTION! Risk of Cuts/Abrasions. Wear protective gloves and safety glasses during installation. Sheet metal edges are sharp.

Figure 5.1 Chimney Requirements


B. Offsets/Returns

A 30° Elbow (measured from the vertical) is the largest that can be used in an offset. A 30° Elbow may not be combined with another Elbow to make a steeper offset (e.g. two 30° Elbows are not allowed to be put together to form a 60° elbow.).

Avoid Elbows if possible. A totally vertical chimney is more efficient. When Elbows are necessary to avoid obstructions such as rafters, ridgepoles, or joists, you are only allowed to use 2 pair of Elbows in any one chimney system. Horizontal runs of chimney violate building code and are not allowed.

• An offset and return can be used as a single entity or separated by chimney section(s).

WARNING! use offset/returns greater than 30° from vertical. Chimney draft will be restricted and could cause overheating and fire.

• Measure the shift needed to avoid the overhead obstruction. Refer to dimension A in Figure 5.2.

• Find the appropriate A dimension listed in Table 5.3. The B dimension coinciding with the A dimension measurement in

Table 5.3 represents the required vertical clearance needed to complete the offset/return.

• Read across the chart to find the number of chimney sections/model numbers needed between the offset and return.

A

B

Example:

Your “A” dimension from Figure 5.2 is 14-1/2 in. (368 mm). Using Table 5.3 the dimension closest to, but not less than 14-1/2 in. (368 mm) is 14-1/2 in. (368 mm) us ing a 30° offset/return.

You determine from the table that you need 34-1/8 in.

(867 mm) (Dimension “B”) between the offset and return.

The chimney component that best fits your application is one SL324.

B. Assemble Chimney Sections

WARNING! Risk of Fire! DO NOT install substitute or damaged chimney components.

Use only those components described in this manual.

Attach either a straight chimney section or an offset to the top of the fireplace starting with the inner flue followed by the outer casing. Continue this order until termination cap is reached (depending on your installation requirement).

Chimney sections are locked together by pushing down ward until the top section meets the stop bead on the lower section.

The inner flue is placed to the inside of the flue section be low it. The outer casing is placed outside the outer casing of the chimney section below it. See Figure 6.2.

NOTICE: Chimney sections cannot be disassembled once locked together. Plan ahead!

• Lock chimney sections and/or offsets/returns together by pushing downward until the top section meets the stop bead on the lower section.

• Pull on the top of each section as installed to make sure it is fully engaged and will not separate.

• You may use #6 or #8 sheet metal screws no longer than 1/2 in. (13 mm) to fasten chimney outer sections together. Do NOT penetrate inner flue.

• Vertical straight runs of chimney must be supported every

35 ft (10.7 m).

• Place the box on top of the fireplace around the chimney pipe, push both pieces together and secure with screws provided.

• Use the pre-punched holes in the tabs as guides and drill holes through the fireplace top.

• Secure the CAK4A in place. See Figure 6.3.

• Seal around the kit at the flue and at the top of the can with high temp caulk with a minimum rating of 500 degrees. See Figure 6.3.

When using the chimney air kit (CAK) and the outside air kits, it is recommended that you install a P trap as shown in Figure 6.4 by bending the flex duct, or using 90° elbows if using rigid duct to help prevent air circulation when the fireplace is not in use. In colder climates, it is strongly recommended to use an insulated duct.

D. Secure Offset/Return


• Secure offsets with screws (not to exceed 1/2 in./13 mm

In length).

• Secure returns with strapping.

• Straight chimney sections may be secured with screw

(not to exceed 1/2 in./13 mm In length) at the joints.

• Keep chimney sections from separating or twisting.

When offsets and returns are joined to straight pipe sec tions, they must be locked into position with screws (outer only). To prevent gravity from pulling the chimney sections apart, the returns and the chimney stabilizers have hanger straps for securing these parts to joists or rafters. See Figure 6.5.

* Use # 6 or # 8 sheet metal screw, or larger, no longer than 1/2 in. (13 mm).


E. Install Firestops

WARNING! Firestops must be used whenever the chimney penetrates a ceiling/floor.

• Mark and cut an opening in ceiling/floor as shown in

Figure 6.6.

• Frame the opening with the same size lumber used in the ceiling joists.

• Nail the firestop to the bottom of the ceiling/floor joists.

• Provide a means to maintain the required air space between the chimney and insulation or install an attic insulation shield.

WARNING! Risk of Fire! DO NOT seal area between firestop opening and chimney pipe except where they en ter the attic or leave the warm air envelope of the home

(use 600° F sealant).


F. Install Attic Insulation Shield

WARNING! Risk of Fire! You MUST install an attic insu lation shield when there is any possibility of insulation or other combustible material coming into contact with the chimney.

• DO NOT pack insulation between the chimney and the attic insulation shield.

• Failure to keep insulation and other materials away from chimney pipe could cause fire.

• DO NOT offset chimney inside insulation shield.

• Combustible material may come in contact with the attic insulation shield as long as the required clearances are maintained to the chimney pipe.

Installation of a ceiling firestop is required:

Note: In Canada a CAS8 must be installed. See instruc tions provided with kit.

• Refer to Figures 6.6, 6.7, 6.8 and 6.9.

• If the attic shield is pre-rolled continue. If it is a flat part, try and roll it up to aid in wrapping it around the chimney.

• Pre-bend all the tabs in at the top to 45°.

• Wrap the shield (around the chimney if already installed) until you have an overlap and the three holes on each side match up (large holes on top).

• Insert three screws into the matching holes to form a tube starting at the bottom.

• Bend the tabs on the bottom of the tube inward to 90° to maintain chimney air space.

• Rest the insulation shield on the ceiling firestop below.

• Tape off any opening around the bottom.

If you wish to make a custom shield or barrier, follow these guidelines:

• Metal is preferred, although any material stiff enough to hold back the insulation can be used.

G. Roof Penetration

• Refer to Figure 6.10.

• Plumb from roof to center of chimney.

• Drive a nail up through roof to mark center of pipe.

• Measure to either side of nail and mark the 14-1/2 in. x

14-1/2 in. (368 mm x 368 mm) opening required.

• Measure opening on the horizontal; actual length may be larger depending on roof pitch.

• Cut out and frame opening.

Install Flashing

• Assemble chimney so it passes through the framed opening.

• Slip the flashing over the chimney.

Roofing shingles must be below the flashing plate on the lower side of a sloped roof and over the flashing plate on the sides and top.

• Nail the flashing to the roof. Keep gaps between the flashing plate and the roof to a minimum.

• Caulk the flashing plate and roof junction as well as the vertical seam on the flashing. All nail heads must be caulked with a roofing sealant.

• Caulk the overlap seam of any exposed pipe sections that are located above the roof line to prevent leaks.

• The thimble must extend completely through the roof structure shielding combustible materials. Five location holes have been provided to allow for a variety of ceiling/ roof thicknesses. A thimble extension is required when the ceiling/roof thickness exceeds 12-1/2 in. (318 mm).

The extension should overlap the thimble one inch.

• To attach the extension to the thimble, drill 1/8 in. (3 mm) holes through the outer shield of the thimble using the predrilled holes in the extension as guides. Attach the extension to the thimble using the screws provided with the extension.

• Install the thimble assembly and nail it securely to the framing members.

Finishing

A. Template

A cardboard template of the front is printed on the outside of the shipping box. Cut out the template along the outside of the line for use in your installation. If using the cardboard template, it will require 1/4-20 bolts to attach it to the fire place, (NOT INCLUDED). A metal template (see catalog) is available for more durable continued use, remaining ac curate over time. Both measure 1/8 in. (3 mm) larger all the way around than the actual front.

Note: This 1/8 in. of the non-combustible material must be painted or the red will be visible.

Tools Required: 5/32 in. Allen wrench.

• Remove the screws from the fascia and remove fascia from the fireplace (if installed). Save the screws. Store the fascia in a safe, protected area to prevent scratching or other damage.

• Install the template on the front of the fireplace (Figure

8.1) with screws removed or provided.

NOTE: Do not over tighten the screws, just tighten up the template enough so that it comes in contact with the outer flanges on the front of the fireplace.

You are now ready to continue your installation with the desired decorative material. The template also serves as a protective covering and prevents damage to the front of the fireplace.

D. Finishing the Hearth Extension

WARNING! Risk of Fire! High temperatures, sparks, em bers or other burning material falling from the fireplace may ignite flooring or concealed combustible surfaces.

• Protective metal hearth strips MUST be installed.

• Hearth extensions MUST be installed exactly as specified.

A hearth extension must be installed with all fireplaces to protect the combustible floor in front of the fireplace from both radiant heat and sparks.

• You MUST use a hearth extension with this fireplace.

• Refer to Figure 8.6 for minimum dimensions.

• This fireplace has been tested and approved for use with a hearth extension insulated to a minimum R value of

1.03.

• The hearth extension material MUST be covered with tile, stone or other non-combustible material.

• Manufactured hearth materials will usually have a published R value (resistance to heat) or k value

(conductivity of heat). Refer to the formula in Table 8.1 to convert a k value to an R value,

• Refer to Table 8.2 for hearth extension insulation alternatives.

Figure 8.8 Raised Hearth Extension to Bottom of Fascia


Hearth extensions are to be installed only as illustrated to prevent high temperatures from occurring on concealed combustible materials.

Vinyl Flooring

Vinyl Flooring is sensitive to heat. A 48 inch minimum depth hearth extension is recommended when using vinyl flooring up to the wall. See Figure 8.8.

Notice: Clearances that do not meet the minimum guidelines could result in damage or buckling to the vi nyl flooring and is done at the installer’s risk.

Hearth and Home Technologies does not recommend adhesive based vinyl flooring due to thermal expan sion. Floating-style flooring can be used, but will reach temperatures up to 110°F in a room with ambient tem peratures of 70°F. Consult flooring specifications to en sure compatibility.

E. Non-Combustible Sealant Material

• After completing the installation of non-combustible facing board in the required non-combustible zone and the non-combustible finishing material over that, remove the template.

• A bead of non-combustible sealant must be used to close off any gaps at the top and sides between the fireplace and non-combustible facing (Figure 8.9) to prevent cold air leaks and the risk of fire. Large gaps can be bridged with fiberglass rope gasket.

• When installation of the decorative material is complete, replace/install the fascia and fireplace doors.

• Maintain clearances.

• Use only non-combustible material below standoffs, material such as cement board is acceptable.

• Framing or finishing material used on the front of the fireplace closer than the minimums listed, must be constructed entirely of non-combustible materials

(i.e., steel studs, concrete board, etc.).

Hearth & Home Technologies is not responsible for discoloration, cracking or other material failures of finishing materials due to heat exposure or smoke.

• Choose finishing materials carefully.

Seal around finishing material to fireplace.

Fireplace Setup

A. Firebrick Placement

The firebox of your fireplace is lined with high quality fire brick, which has exceptional insulating properties.

Do not use a grate; simply build a fire on the firebox floor.

Do not operate the fireplace without bricks. Make sure bricks are installed as shown.

IMPORTANT: Be certain you have the proper brick in the correct location. Measure the brick size for accuracy.

- Remove new brick set from box and lay out to diagram as shown in Figure 9.1

.

- Lay bottom bricks in firebox.

- Install rear bricks on the top of the bottom bricks. Slide top of bricks under clip on back of firebox wall and push bottom of brick back.

- Install side bricks. Slide top of brick under clips on side of firebox and push the bottom of the brick until it is flush with the side of the firebox.
