Ortal USA Fireplaces with Double Glass (DG)
Maintaining cool air flow between the glass panels and through the chase
cavity.
In order to maintain air flow between the glass panels and to allow cool “outside” air (room air
from outside the firebox) to enter into the chase cavity, an opening must be provided in the
exterior finish surface underneath the firebox. Please refer to the attached sketch and the criteria
below.
Please make sure this detail is included prior to closing the wall surface below the fireplace.
Air Opening Q & A:
Q. How much of an opening needs to be provided?
A. If the unit is in series 40-130, including Space Creator 75 and 120, the total opening
surface area must be a minimum of 124 sq in. If the unit is in series 150-200, the total opening
surface area must be a minimum of 200 sq in. There may be more than one opening, but the total
area needs to achieve this amount. It is recommended to have more than one opening location for
better air flow.
Q.
If your fireplace is standing on a raised platform above the floor, where should the
opening be placed?
A. The opening(s) can be above or below the platform, but must be below the bottom
surface of the firebox (not including the legs). Sketch #1 shows the opening between the platform
and the underside of the firebox. Sketch #2 shows the opening between the platform and the sub-
floor in which case there must be an opening in the platform allowing air passage through the
platform surface into the void below the firebox.
Q. Why are these openings required?
A. Ortal’s standard units bring outside air through the firebox top frame into the chase.
The exterior double glass panel closes the access for air flow through this channel. Therefore, air
flow needs to be maintained from the bottom of the firebox frame.
Q. Should this application be provided for standard units without double glass?
A. It is not required as air flow is maintained from passage around the glass panel to the
firebox frame. However, it cannot hurt and is a benefit to have additional air circulation in the
chase if this air access point is added below the firebox, as well.
NOTE:
Power requirement:
Please make sure to prepare 110 volt 20 amps dedicated power line (outlet)
at the bottom area of the unit to provide power for the fan which circulates air between the panels
and through the chase.
