5 Overview and Checklist This manual provides information, diagrams, instructions and recommendations related to preparing a building site for installation of an ORTAL fireplace and vent. ORTAL fireplaces must be installed in accordance with the ORTAL Installation and Operation Manuals and applicable codes. An authorized dealer will install the direct vent pipe, make gas and power connections, and provide fire stopping or thimble where direct vent pipe penetrates the wall or ceiling of the chase. Installation must be performed by an ORTAL Authorized Installer. Installation by any other party invalidates the warranty. Keep the following tips in mind as you plan the project: Do not allow delivery of the ORTAL fireplace to your jobsite until building is enclosed and ready for installation. Protect the fireplace against damage throughout construction. Notify authorities having jurisdiction to inspect work before the chase is enclosed (if required). Project Planning Checklist Review the following requirements and tips carefully as you plan the project. Fireplace Model and Size: Ensure that the fireplace delivered matches the model and size in the order. Gas Type: Check whether you will be working with propane or with natural gas. Optional Features: Clarify whether the project will include features such as Double Glass fan assisted (upgrade from screen barrier) Power Vent System Wall Control Switch Power Heat Release System Fireplace Location and Venting: Make sure that adequate space is provided to vent the fireplace from its desired location to the termination outside of the structure. For details, refer to Airflow: Description and Guidelines on page 9. Access Panel for Control Valve: See Gas Valve Access Panel on page 10. Gas Supply Line: Must run to fireplace valve location and include shutoff to allow for flex line to be attached to valve. The line must have a manual shutoff in the same room as the fireplace (within 4 of the fireplace, or per local code). Power Location: Provide a single gang 120v 15 amp outlet in the same area as the valve behind the access panel. The unit requires a 6v transformer supplied with the fireplace to run without batteries. Heat Release Air Return to Room: Make sure the size of the heat release is verified and located. For details, refer to Sizing Guidelines for Air Intake and Heat Release on page 9. Ortal Builder's Manual 5

6 Air Intake (required for double glass models): Make sure the size of the air intake is verified and located. For details, refer to Sizing Guidelines for Air Intake and Heat Release on page 9. Platform Height: This determines the height of the viewable glass opening. For specific unit dimensions, see the CAD drawings on the ORTAL website. Type X Sheetrock in Chase Area: All combustible framing in the chase area must be completely covered with 5/8 Type X drywall or its equivalent. All weight must be supported by the framing and transferred to the fireplace. No building material should be attached to the fireplace, with the exception of the Type X drywall (or its equivalent) in a flush install. It may be secured to the unit with 1" self tapping screws 2 ½ up from the drywall lip spaced 16'' on center. Non combustible Areas: Maintain a 2 clearance on sides and back of the firebox to the Type X drywall (or its equivalent). Final Wall Finish: Wall finish materials should be reviewed with your dealer to ensure that clearances and materials conform to ORTAL clearance requirements. For more information, refer to Finishing Details on page Ortal Builder's Manual

7 Firebox Clearances This Builder s Manual is based on installation of front facing ORTAL fireplaces. To install other ORTAL fireplace styles, modify the instructions per ORTAL Framing Dimensions. Maintain clearances as shown in the figures below. Clearances are to non combustible materials, or 5/8 Type X fire rated drywall or its equivalent.

9 General Guidelines Before you begin, read the following guidelines about airflow and the gas valve. Airflow: Description and Guidelines An ORTAL fireplace requires two airflow paths, for: Exhaust and combination air Cool wall air The exhaust and combination air path involves the direct vent exhaust system, which consists of the air inside the firebox and the direct vent pipe. A direct vent pipe has an inner and outer channel. Hot exhaust gases (mostly carbon dioxide and water vapor) escape through the inner channel. Fresh outdoor air (providing oxygen for the fire) is drawn in through the outer channel, where it captures most of the heat escaping through the inner channel. Cool wall air flow refers to the heat release system and air intake. The chase enclosing an ORTAL fireplace must have a heat release above the fireplace. This allows for the heat buildup within the fireplace chase to be released back into the living space, which helps keep the fireplace wall cool. Fireplaces with the double glass feature must have an air intake. Room air is drawn between the glass, into the chase and then is returned to the room through the heat release. These airflows, along with radiant heat from the front of the fireplace, maximize the heating performance of an ORTAL fireplace and contribute to its energy efficiency. Cool Wall Airflow Intake ORTAL fireplaces with double glass require an intake located below elevation of the fireplace. The air intake can be a grille or louver, or an opening on the underside of the chase. For screen units, the screen serves as the air intake. Heat Release A heat release mechanism is required for all built in models. The heat release must be interior. It should be located a maximum of 6 inches from the top of the fireplace chase. It can be a grille or louver, or a gap between the top of the chase wall and the ceiling. Sizing Guidelines for Air Intake and Heat Release The minimum free area (net area after grillwork or screens are subtracted) should be: Ortal Models 40 to 130: 124 sq.inches or more Ortal Models 150 to 200: 200 sq.inches or more Ortal Model 250: 250 sq.inches or more Other Models: Check with ORTAL Ortal Builder's Manual 9

10 Gas Valve Access Panel A gas valve should be installed below elevation of the firebox. An access panel is recommended for easy servicing of the gas valve. The panel should be a minimum size of 10 x 10. If a larger panel is required to conveniently reach the valve, increase these dimensions. NOTE:.For power vents, a 12 x 12 panel is recommended. An appropriately sized air intake can be used as an access panel. Refer to Sizing Guidelines for Air Intake and Heat Release on page Ortal Builder's Manual

11 Heat Release and Air Intake Construction The following sections present guidelines and diagrams related to building the heat release and air intake: Safety Precautions on page 11 Working with Reveal or Gap Openings on page 11 Working with Louver or Grill Openings on page 13 Safety Precautions Always adhere to the following guidelines to ensure safety and to protect equipment: Know the building code and consult with authorities having jurisdiction before proceeding. This Builder s Manual contains minimum requirements. You may need to modify details provided to satisfy project requirements. External surfaces of ORTAL fireplaces and areas exposed to radiant heat from fire will get hot. Observe required clearances between the fireplace and combustible materials. Artwork and devices such as TVs, audio speakers and light fixtures to be mounted on the chase or recessed into a wall of the chase must have a double wall of 5/8 Type X fire rated gypsum board (or its equivalent) with a 7/8 high hat channel installed vertically in between to prevent direct heat impact. For more information, refer to TV Detail on page 26. Protect the fireplace against damage throughout the construction period.

Be sure to keep the top of the firebox clear of obstruction and to maintain all clearances. A heat release on top of the shelf is needed only if the shelf surface area exceeds what is shown in the above table 25% in the shelf and 75% in the chase. Two layers of Type X (or its equivalent) below the shelf will help keep the surface temperature down. 30 Ortal Builder's Manual

31 Securing the Unit All built in fireplaces come with legs and with seismic brackets at the top of the firebox. These brackets are an additional way to secure the firebox in the chase while still maintaining the air clearances outlined in this manual. You may use either the seismic brackets or heavy duty steel brackets to mount the firebox to the back chase wall, while still maintaining the required 2'' air clearance. If the seismic brackets do not extend all the way to the chase wall, you may extend metal studs to connect to your seismic brackets. Use the leg shipping brackets to secure to the floor. Freestanding and wall mounted ORTAL fireplaces need to be secured to the wall or the floor. If the fireplace is located against a wall, the wall must be made of non combustible material or covered with 5/8'' Type X gypsum board or its equivalent. Ortal Builder's Manual 31

33 Chase Construction The following sections provide details about each phase of building the chase. NOTE: These guidelines are recommendations. Local Building Codes may supersede these guidelines. Overview of the Construction Process on page 33 Building Back and Side Walls on page 34 Installing the Fireplace and Venting on page 36 Building the Front Walls on page 36 Building the Infill Panel on page 39 Completing Construction on page 41 Overview of the Construction Process The process of building the chase can be divided into five main phases. PHASE 1 STEPS: Frame the back and side walls. Build the platform (if relevant) to the desired height. Cover with 5/8" Type X gypsum board or its equivalent (unless the entire adjacent structure is noncombustible). For details about Phase 1, refer to Building Back and Side Walls on page 34. PHASE 2 STEPS: Install the fireplace and venting. Move the valve to the access panel location. Run gas and electric to the access panel location. For details about Phase 2, refer to Installing the Fireplace and Venting on page 36. PHASE 3 STEPS: Build the front walls and stand them into place. Secure the walls to the structure. For details about Phase 3, refer to Building the Front Walls on page 36. PHASE 4 (relevant for wood framing only): Build and install the infill panel. For details about Phase 4, refer to Building the Infill Panel on page 39. PHASE 5 STEPS: Apply finishes and install accessories. Turn the project over to the customer. For details about Phase 5, refer to Completing Construction on page 41. Ortal Builder's Manual 33

34 Building Back and Side Walls The sections below provide details about framing the back and side walls. If a platform for the fireplace is necessary, it should be built during this stage. Walls, Ceiling and Floor When planning the project, take into consideration whether framing will be non combustible or combustible. Non combustible Framing The wall behind an ORTAL fireplace (either at the back or side of the fireplace) and the ceiling above the unit must be non combustible construction such as concrete, brick, concrete masonry units, or plaster on metal framing and lath. Penetrations in the wall or ceiling, such as electrical boxes, must be removed and patched to assure integrity of the non combustible enclosure. Combustible Framing The first 18'' (minimum) of framing MUST be non combustible (steel studs). Existing walls or ceilings built of combustible materials may be used if the wall or ceiling is covered with 5/8 thick Type X gypsum board or its equivalent. An exception to this rule is when the walls of the chase do not extend all the way to the ceiling and allow a gap for heat release. In this scenario, ½ thick Type X gypsum board (or its equivalent) may be used to match the thickness of gypsum board used on the ceiling outside the chase. 34 Ortal Builder's Manual

35 Floor An ORTAL fireplace can be set on wood, concrete, metal and other typical solid floor types. ORTAL fireplaces come with legs that position the unit above the floor or platform on which they are installed. (See shop drawings for height.) To raise an ORTAL fireplace, build a stable platform to which the unit can be secured. This is also the time to make sure power and gas lines are in place. Provide a grounded 120V, 15 Amp single gang box inside the chase for use by the ORTAL installer. Drywall Chase Interior Wood framing inside the chase must be covered with Type X gypsum board or its equivalent. In remodeling projects, apply a layer of Type X gypsum board (or its equivalent) over existing material, unless it is certain that the existing surfaces are 5/8" Type X gypsum board or another acceptable non combustible material. Ortal Builder's Manual 35

36 Installing the Fireplace and Venting ORTAL fireplaces must be installed in accordance with the ORTAL Installation and Operation manuals and applicable codes. Install the direct vent pipe, make gas and power connections, and provide fire stopping or thimble where the direct vent pipe penetrates the wall or ceiling of the chase. Building the Front Walls In most projects, you will probably want to postpone installation of the front wall of the chase. This will allow access for installing drywall inside the chase, positioning the ORTAL fireplace and direct vent pipe, and making necessary connections. Install framing in accordance with building codes and project specifications. All studs are placed 16 inches on center, or per local code. Plan your work carefully, paying particular attention to: Required clearances Blocking for securing the fireplace, direct vent pipes, mantles, drywall, etc. Access panel for the gas valve (Gas Valve Access Panel on page 10) Heat release and air intake (Heat Release and Air Intake Construction on page 11) Direct vent, direct vent strapping, and penetrations through walls and ceiling Recesses for TV, audio speakers, light fixtures, art work, and other items built into chase (if required) Take a moment for a final visual inspection of the chase interior. Remove any construction debris that may be inside the chase. Install conduit, wiring, power outlets, and electrical boxes between framing members with 5/8 Type X or its equivalent on both sides. Building and structural loads must not bear on the ORTAL fireplace. 36 Ortal Builder's Manual

37 Ortal Builder's Manual 37

38 Working with Drywall Cover the metal framing with 5/8" thick Type X gypsum board (or its equivalent) to exterior face of the chase. Exceed these requirements where fire resistance rated construction or other methods are required. Type X gypsum board or its equivalent must comply with ASTM C1396 Specification for Gypsum Board. Provide Level 1 or better finish, in accordance with GA 214 Recommended Levels of Gypsum Board Finish. Do not locate exposed gypsum board joints directly above the fireplace. If corner beads and other drywall trim are required, use metal products where non combustible materials are required. For maximum Cool Wall effect, cover both the interior and exterior of steel studs. 38 Ortal Builder's Manual

39 Building the Infill Panel An infill panel is required only when the design involves wood framing. Follow these steps to complete the infill panel: STEP 1: Build the Infill Panel Build the infill panel flat on the floor. The face that will be inside the chase should be facing up it as it lies on the floor. The infill panel and fireplace should NOT be load bearing. Pay particular attention to the details and clearances required for any recesses for TV or art. Provide blocking for anchorage of TV or heavy artwork, and brace the recess to prevent sagging. For more information, refer to TV Detail on page 26. STEP 2: Drywall the Inside of the Infill Panel Apply 5/8" thick Type X gypsum board or its equivalent to the inside surface of the infill panel. This surface is the top of the panel as it lies on the floor. Ortal Builder's Manual 39

40 STEP 3: Install the Infill Panel Take a moment for a final visual inspection of the chase interior. Remove any construction debris that may be inside the chase. Lift or tilt the infill panel into position. Secure it to the framing of the chase. 40 Ortal Builder's Manual

41 Completing Construction The final stages of construction involve applying finishing and turning the product over to the customer. Adding Finishes and Accessories Now is the time to apply decorative finishes to the exterior of the fireplace chase. For more information about the different finishes, refer to Finishing Details on page 18. Any required accessories, such as mantels, TV mounts, and other features should also be installed at this time.) For more information, refer to Mantel Detail on page 24 and TV Detail on page 26. Observe clearance requirements for combustible materials. Delivering the Product to the Customer Your ORTAL dealer will install interior design media, remove protective materials from and clean exposed surfaces of the fireplace, and perform the start up inspection and initial burning. The dealer will provide the following materials: Ortal Installation and Operation Manual Ortal Fireplace Owner s Manual Executed warranty Operation control(s) Demonstrate operation of the ORTAL fireplace to the customer.
