Installation Prior to Installation Locate the Fireplace Keep the following factors in mind when selecting a location for the fireplace: Fireplace clearance requirements (review “General Clearances” section on page 16). Heat release and air intake requirements (review “Heat Release” section on page 17 and “Air Intake Opening” section on ... -
Page 9: Third Trip To Site: Startup
Securing the Fireplace The fireplace has nailing flanges attached to the face of the fireplace (see figures below). The nailing flanges are to be attached into the framing upon installation. It is crucial to the finishing that the fireplace is stable, level, and plumb. For added stability (though not required), re-use the shipping brackets to secure the legs of the fireplace to floor/platform. -
Page 10: Post-Installation
In addition, the installer must review and explain the following to the owner: Safety warnings Fireplace operation Warranty requirements Maintenance requirements Glass is hot during and after operation. If any questions or concerns arise, owner must contact the local Ortal dealer/installer for support. ... -
Page 11: Building Around The Fireplace
Building Around the Fireplace Building Checklist The following building checklist is a quick reference for a typical Wilderness 77H series fireplace installation. This list is not exhaustive and does not supplement thorough review of the installation manual. Fireplace Location: Ensure the location allows for min. 16” clearance from viewing area to furniture and other combustibles. -
Page 12: Framing
Framing Framing Requirements Fireplace chase may be framed with either combustible (typically wood studs) or non-combustible framing (typically metal studs). Any framing within 10 ” from the top of the fireplace glass (viewing area) must be non-combustible. Any framing after that point may be combustible. -
Page 13: Framing Dimensions
Framing Dimensions The following diagrams are for illustrative purposes only. There are multiple approved framing scenarios. A flush application is not the only permitted application. The fireplace may be recessed into the wall. Refer to diagrams and values below and in the following pages for details. - Page 14 Wilderness 77H Corner (RS/LS) Series Fireplace Glass Glass Height Length Depth Stand-Off Legs Length Height 77H RS/LS ” ” ” ” ” 78 ¾” ” Screened 77H RS/LS ” ” ” ” ” " ” Double Glass Framing 77H RS/LS 77H RS/LS Fireplace Screened...

Page 16: General Clearances
General Clearances Viewing Area Clearance Zone The viewing area clearance zone is an area that extends perpendicular from the fireplace viewing area. The depth of the viewing area clearance zone depends on the combustibility of the material in question. Distance is measured from the fireplace heat barrier. Non-Combustible Materials Must be minimum 12 inches from fireplace viewing area. -
Page 17: Heat Release
Heat Release A heat release is an opening in the fireplace chase that allows the heat inside the chase to passively circulate into an interior room. This heat is generated convectively as the fireplace heats up. It is separate from exhaust heat produced in the combustion chamber of the fireplace. - Page 18 Vertical Heat Release: Split Front Vertical Heat Release: Full Side The heat release is oriented vertically and split between the two The heat release is oriented vertically. Entire heat release sides of the chase. is on one side of the fireplace chase. Split Front Vertical Heat Release Full Vertical Heat Release on One Side Sprinkler Clearance to Heat Release...
-
Page 19: Air Intake Opening
Air Intake Opening For fireplaces with a double glass heat barrier only, an air intake opening must be incorporated into the framing and finish around the fireplace. The air intake opening is essential to maintain cool air flow between the double glass panels by allowing the double glass fans to circulate room air through the glass panels and up into the chase. -
Page 20: Air Intake For A Platform
Air Intake for a Platform NOTE: Please refer to the “Chase Floor/Platform” section on page 12 for details on platform construction. -
Page 21: Mounting A Tv/Artwork
The decision to install a television above an Ortal fireplace is up to the discretion of the owner. TV and art manufacturers may specify that their product should not be installed on, near or above a heat source. Ortal will not be held liable for any adverse effects on a TV, artwork or other equipment located near the Ortal fireplace. - Page 22 Recessed TV/Artwork When the TV is mounted on a wall that recesses over fireplace, the TV must be at least 12 inches from the top of the fireplace glass viewing area. At 12 inches above the fireplace viewing area, maximum possible recess is 5 inches. A deeper recess will interfere with required clearances to venting.
-
Page 23: Access Area Requirements
Access Area Requirements An access panel, or some other form of clear access, is required at each of the following two locations for servicing purposes: Power Vent Control Box Power Vent Fan Box Prior to installation, fireplace dealers/installers should work with the owner, builder, project architects and/or interior designers to determine the best size and location of their access panel depending on project design needs. -
Page 24: Chase Area Minimum
Chase Area Minimum To ensure the convective heat within the chase passively moves to the heat release at an optimal rate, all parts of the interior of the chase must at least the same size as the fireplace heat release (see “Heat Release” section on page 17 to determine your model’s required heat release size) at size at any given point. -
