  • Page 9: General Guidelines

    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.
  • Page 10: Gas Valve Access Panel

    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 ...
