• 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.
• Installing the fireplace in a basement is not recommended.
• 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 4 and 5.
• Install the outside 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
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.
In cold climates, Hearth & Home Technologies recommends that the chase be well insulated using batt type insulation between the joists.
Construction of the chase may vary with the type of building. These instructions are not substitutes for the requirements of local building codes. Local building codes MUST be checked.
Chases should be constructed in the manner of all outside walls of the home to prevent cold air drafting problems.
The chase should not break the outside building envelope in any manner. All outer walls need to be insulated.
Building codes require false ceiling and ceiling firestops/ attic shields at each floor of the chase or every 10 ft (3048 mm) of clear space to control spread of fire.
Walls, ceiling, base plate and cantilever floor at the first level of the chase should be insulated (see Figure 3.3.)
Vapor and air infiltration barriers should be installed in the chase as per regional codes for the rest of the home. Additionally, Hearth & Home Technologies recommends that the inside surfaces be drywalled and taped (or the use of an equivalent method) for maximum air tightness.
Holes and other openings should be caulked with high temperature caulk or stuffed with unfaced fiberglass insulation.
WARNING! You must install false ceilings and ceiling firestops at each floor of the chase or every 10 ft
(3.05 m) to control spread of fire.

Figure 3.3 Chase Assembly
Insulation in the outside walls of the chase
WARNING! Risk of Fire! You must maintain a minimum
2 in. (51 mm) air space clearance to insulation and other materials surrounding the chimney system.
• Insulation and other materials must be firmly secured to prevent accidental contact with chimney system.
• The chase must be properly blocked to prevent blown insulation or other combustibles from entering and making contact with fireplace or chimney.
• Failure to prevent contact between insulation or other materials and chimney system may cause overheating and fire.
Three examples of chase applications are shown in Figure 3.4.
1. Fireplace and chimney enclosed in an exterior chase.
2. Chimney offset through exterior wall and enclosed in chase.
3. Chase constructed on roof.
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).
• 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 3.3. This will help reduce heat loss from the home around the fireplace.
Note: In cooler climates, all chase walls should be insulated.

D. Frame the Fireplace
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 is 7 1/2”. If you want a higher raised hearth the fireplace must be placed on a platform.
WARNING! Risk of Fire. A raised hearth extension built flush with the fireplace opening or less than 4 in. (102 mm) below the fireplace opening requires the fireplace be installed on a non-combustible surface.
WARNING! Risk of Fire! Comply with all minimum clearances specified.
• A minimum 1/2 in. (13 mm) air clearance must be maintained at the back and 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 minimum air space clearances to combustibles. DO NOT pack required air spaces with insulation or other materials.
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. Any framing across the top of the fireplace must be above the level of the top standoffs. (No recess above standoffs.)
2 in. (51 mm) min. air space clearance from chimney.
The finished cavity depth must be no less than 21 3/8 in.
(543 mm) from the finished backwall to the outside of front wall framing. Framing must extend straight up all the way to the ceiling.
CAUTION! Risk of Cuts/Abrasions. Wear protective gloves and safety glasses during installation. Sheet metal edges are sharp.
E. Secure and Level the Fireplace
This fireplace may be placed on either a combustible or noncombustible continuous flat surface. Follow the instructions for framing in Section 3. Slide the fireplace into position. Be sure to provide the minimum 1/2 in. air clearance at the sides and 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.
Level the fireplace and shim as necessary.
WARNING! Risk of Fire! Prevent contact with sagging, loose insulation.
• DO NOT install against vapor barriers or exposed insulation.
• Secure insulation and vapor barriers.
• Provide minimum air space clearances at the sides and back of the fireplace assembly.

F. Protective Metal Hearth Strips
WARNING! Protective metal hearth strips MUST be installed on combustible surfaces. DO
NOT cover metal strips with combustible materials.
Sparks or embers may ignite flooring.
WARNING! High temperatures, sparks, embers 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.
• Locate the two protective metal hearth strips measuring approximately 26 in. x 4 in. (660 mm x 102 mm) included with this fireplace.
• Slide each metal strip 2 in. (51 mm) under front edge of fireplace.
• Overlap strips in the middle of fireplace opening by 1 in.
(25 mm) minimum.
• Metal strips must extend beyond the front and sides of the fireplace opening by at least 2 in. (51 mm),
Figure 3.6).
• Protect the front of a platform elevated above the hearth extension with metal strips (not included with fireplace) per Figure 3.6. See Section 7 f or hearth extension instructions.

G. Outside Air Kit (optional)
If you install an outside air kit, Hearth & Home Technologies recommends you utilize the shortest duct run to optimize the performance of the outside air kit. The outside air inlet hood should be positioned 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 3.8 and 3.9 when placing the outside air inlet hood.
The outside air kit is installed on the left hand side of the fireplace.
• Cut a 4 in. (102 mm) hole in outside wall to accommodate air piping.
• Use 4 in. (102 mm) flex (not supplied) to directly connect outside air to fireplace intake. Insulate the pipe to prevent frost condensation.
• 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 Cuts/Abrasions. Wear protective gloves and safety glasses during installation. Sheet metal edges are sharp.

B. Offsets/Returns
• Use an offset/return to bypass overhead obstructions.
• An offset and return can be used as a single entity or separated by chimney section(s).
Risk of Fire! DO NOT use offset/returns greater than 30°. Chimney draft will be restricted and could cause overheating and fire. Secure offsets with screws ( not to exceed 1/2” / 13 mm in length) Secure returns with strapping.
Straight chimney sections may be secured with screws. Keep chimney sections from separating or twisting.
• Measure the shift needed to avoid the overhead obstruction. Refer to dimension A in Figure 4.2.
• Find the appropriate A dimension listed in Table 4.3. The B dimension coinciding with the A dimension measurement in
Table 4.3 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.

Example:
Your “A” dimension from Figure 4.2 is 14-1/2 in.
(368 mm). Using Table 4.3 the dimension closest to, but not less than 14-1/2 in. (368 mm) is 14-1/2 in. (368 mm) using 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.

Figure 5.1 Typical Chimney System - Guidelines for Chimney System Installation
18 Heat & Glo • RH36/RH42 • 4044-194 Installation Manual • Rev D • 10/09/13
B. Assemble Chimney Sections
Use only those components described in this manual.
Substitute or damaged chimney components could impair safe operation and cause overheating and fire.
Attach either a straight chimney section or an offset to the top of the fireplace (depending on your installation requirement). Chimney sections are locked together by pushing downward until the top section meets the stop bead on the lower section.
The inner flue is placed to the inside of the flue section below it. The outer casing is placed outside the outer casing of the chimney section below it. See Figure 5.2.
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 section 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 sections together. Do
NOT penetrate inner flue.
WARNING! You MUST use screws (provided) to fasten offset/returns to chimney sections to keep the chimney parts from twisting. Failure to do so could cause fire.
• Fasten offset/returns to chimney sections. Insert the screws (provided) through the predrilled holes. Do NOT penetrate inner flue.
• Secure chimney returns with hanger straps provided; fasten to studs or joists.
• Vertical straight runs of chimney must be supported every
35 ft (10.7 m).
C. Install Chimney Air Kit
• Required in Canada.
• Follow instructions included with accessory.
Figure 5.2 Assembling Chimney Sections
WARNING! Risk of Fire! DO NOT install substitute or damaged chimney components.
Heat & Glo • RH36/RH42 • 4044-194 Installation Manual • Rev D • 10/09/13 19
D. Secure Offset/Return
When offsets and returns are joined to straight pipe sections, they must be locked into position with the screws provided* (outer only), using the predrilled holes. 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 5.3.
* Use # 6 or # 8 sheet metal screw, or larger, no longer than 1/2 in. (13 mm).
WARNING! Risk of Fire!
• 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.

E. Install Ceiling Firestops
CAUTION! Ceiling firestops must be used whenever the chimney penetrates a ceiling/floor.
• Chase construction requires ceiling firestops at each floor or every 10 ft. (3.05 m) of clear space.
• The ceiling firestop slows spread of fire and reduces cold air infiltration.
• Install a ceiling firestop whenever chimney penetrates ceiling/floor.
• Mark and cut an opening in ceiling as shown in Figure 5.4.
• Frame the opening with the same size lumber used in the ceiling joists.
• Nail the ceiling firestop to the bottom of the ceiling joists when there is a room above.
• Use an attic insulation shield if the ceiling is insulated.
The ceiling firestop may then be attached above or below the joists.
Figure 5.4 Installing the Ceiling Firestop
WARNING! Risk of Fire! DO NOT seal area between firestop opening and chimney pipe except where they enter the attic or leave the warm air envelope of the home
(use 600° F sealant).
20 Heat & Glo • RH36/RH42 • 4044-194 Installation Manual • Rev D • 10/09/13
► F. Install Attic Insulation Shield
WARNING! Risk of Fire! You MUST install an attic insulation 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.
Installation of a ceiling firestop is required:
• Refer to Figures 5.5, 5.6, 5.7.
• Roll the shield (around the chimney if already installed).
The three holes on each side will match up (large holes on top).
• Insert three screws into the matching holes to form a tube.
• 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.
• Bend the tabs at the top of the shield inward to 90° to maintain the 2 in. (51 mm) air space from the chimney.
Insert three screws

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.
WARNING! Use of cardboard or other materials that can deflect under humidity or other environmental conditions is not recommended.
• The shield or barrier must be tall enough to extend above the insulation and prevent blown-in insulation from spilling into the cavity.
• Maintain specified air spaces around chimney.
• Check instructions and local codes for further details.
Double-check the Chimney Assembly
Continue assembling the chimney sections up through the ceiling firestops as needed. While doing so, be aware of the height and unsupported chimney length limitations given under Section 5.
Check each section by pulling up slightly from the top to ensure proper engagement before installing the succeeding sections. If they have been connected correctly, they will not disengage when tested.

G. Roof Penetration
• Refer to Figure 5.8.
• 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.
• Refer to Chapter 25 of the Uniform Building Code for roof framing details.
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.
H. Install Chase/Chase Top
• You MUST use a chase top in a chase installation.
Chase tops are available from your Heat & Glo dealer or may be field constructed.
• Include a turndown and drip edge to prevent water from seeping into the chase.
• Include a 2 in. (51 mm) soldered, welded or spun collar around pipe opening to keep water out.
• Provide a 1/8 in. (3 mm) gap around the flue pipe.
• Slope the chase top downward away from the opening.
Risk of Fire! DO NOT caulk the pipe to the chase top collar.
• Caulk all seams to prevent leaks.

Finishing
A. Finishing Material
Refer to Sections 1.B. and Sections 1.C. for combustible/ non-combustible materials. Refer to Figure 7.1 for noncombustible zone.
WARNING! You must maintain clearances.
• Do NOT cover metal fireplace front with combustible materials.
• Install combustible materials only to specified clearances on top front and side edges.
• Complete framing and apply facing material (drywall) over framing.
• A bead of 300-deg F minimum non-combustible sealant must be used to close off any gaps at the top and sides between the fireplace and facing to prevent cold air leaks.
• Large gaps can be bridged with fiberglass rope gasket.
• Only non-combustible materials may be used to cover the metal fireplace front.
These surfaces may be covered with non-combustible material.

B. Hearth Extension, Building and Finishing
WARNING! Risk of Fire! High temperatures, sparks, embers 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 7.3 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
7.1 to convert a k value to an R value,
• Refer to Table 7.2 for hearth extension insulation alternatives.
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.
WARNING! Risk of Fire!
• 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.).
WARNING! Risk of Fire!
Hearth extensions are to be installed only as illustrated to prevent high temperatures from occurring on concealed combustible materials.
