Double Glass Requirements; Power Requirements; Air Intake Requirements - ORTAL 40 Series Installation And Operation Manual

When installing a double glass Ortal fireplace, it is essential to maintain cool air flow between the glass panels and
through the chase cavity. To maintain air flow between the glass panels and to allow cool room air to enter the chase
cavity, an opening must be provided at or below the level of the double glass fans. This opening, called an air intake,
needs to be made before closing the wall surface below the fireplace.

Power Requirements

Prepare a 110-volt 15-amp dedicated power line (2 gang outlet) to the access panel area (or near the burner area if
an access panel isn't available) to provide power for the double glass fans that circulate cooling air between the
safety barrier glass panels and up through the chase.
The following diagrams show two options for constructing the chase cavity air intake when the fireplace is located
on a platform. Please note that these drawings are not to scale. All fireplace drawings with correct dimensions are
available on our website.

Air Intake Requirements

Each series has a minimum air intake size requirement:
Fireplace Series
These air space values are the minimum required; they can always be greater. The air intake can be in the form of a
ventilation grille (louver), gap, or toe kick. If using a grille, make sure that the net free airspace allowed in the
louvered area is equal or greater than the minimum number of square inches required per unit.
The air intake is not required to be on the front wall of the fireplace. As long as the entire air intake is located at or
below the level of the fans, it can be on the front, the back, or sides of the wall, or any combination thereof on an
interior wall. An air intake cannot be on an exterior wall.
