Appliances and Flue Clearances: Overview
The appliance is approved with maintained minimum clearance to combustible materials, as shown in the
diagrams provided in this chapter.
Non-combustible materials, such as surrounds and other appliance trim, may be installed on the appliance face
as long as the minimum clearances are maintained between the appliance and the non-combustible material.
Surrounding material is not allowed to transfer weight to the unit or be connected in any way to the unit, with
the exception of the Gyprock Fyrchek drywall (or its equivalent) in a flush install. It may be fastened to the frame
with 2.5cm self-tapping drywall screws 40cm on center, with a minimum of 6.5cm from the glass lip. It must not
transfer weight to the fireplace, or cover any portion of the removable glass panel or the control compartment.
The minimum clearances (air space) to combustible materials must be adhered to. It is of the greatest
importance that the fireplace and flue system be installed only in accordance with these instructions.
Concepts and Definitions
x
Access Panels: These are typically required for all ORTAL fireplaces. They allow for efficient and
comfortable access to the fireplace receiver and valves, which is required to service the unit(s). Also,
access panels can be uniquely placed and designed to not disturb the aesthetic incorporation of the
fireplace to its surrounding living space. The size of the Access Panel may vary, but in all cases must
allow the fireplace technician to effectively access and service the valve and receiver if required.
However, access panels are not the only option for servicing the fireplace operation mechanisms. A
technician may also service the fireplace controls by going through the firebox. This procedure requires
removing the glass panel(s), taking out the interior design media and lifting the grill, burner and bottom side
(explosion valve) of the unit. The technician would then return all these fireplace components when service is
complete.
Fireplace dealers/installers are advised to consult with their clients, project architects and/or interior
designers regarding the advantages and disadvantages of each service option.
x
Framing and Drywall: Fireplace chase may be framed with metal studs or wood studs. Wood must be
covered completely with non-combustible material and have the gaps sealed with a non-combustible
fire sealant. We recommend using 16mm Gyprock Fyrchek fire rated drywall or its equivalent for the
enclosure of the fireplace chase. The framing of the fireplace chase wall must be designed to carry the
entire weight of the wall. Plan to include weight of other finish materials placed on the drywall.
x
Heat Release: Heat release is required for all models except the Console Appliances. This allows for
heat building up within the fireplace chase to be released back into the space, helping to keep the
fireplace wall cool. It must be located at the top of the fireplace chase and be placed a maximum of 15
cm below the fireplace chase ceiling. It can be located on the front, sides or back of the fireplace chase,
as long as it is being released into an interior space and not outdoors. A minimum air space is required
per series:
x
Minimum 0.13 sq. meter. of free air space for Series 150-200
x
Minimum 0.16 sq. meter. of free air space for Series 250
These air space values are the minimum required- they can always be greater. The heat release can be added
as a louver or as a reveal. If using a louver, make sure that the free airspace allowed in the louvered area is
equal or greater than the minimum number of square meters required per unit.
