Double Glass Requirements

When installing a double glass ORTAL appliance, 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 appliance
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:
Series 40-130: Minimum 124 sq. in. of free air space
Series 150-200: Minimum 200 sq. in. of free air space
Series 250: Minimum 250 sq. in. of free air space
These air space values are the minimum required; they can always be greater. The air intake can be in the
form of a ventilation grill (louver), gap, or toe kick. If using a grill, 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 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.
