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.
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 9. 10 Ortal Builder's Manual ...

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.
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.
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.
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 ...
