Fire Rated EAC
Introduction
This product has been provided with a butterfly closer (Enviroseal) to comply with The Australian
Standards AS3959-2009 Construction of Buildings in bushfire prone areas. Additionally ember
protection consisting of stainless steel mesh is provided as a cover over the filters of the unit.
These product enhancements enable the product to comply with the requirements of
AS3959 - 2009:
•
BAL - 12.5
•
BAL - 19
•
BAL – 29
Achieving the fire rating BAL Codes listed above requires the Enviroseal to be fitted in accordance
with its installation instructions (provided with the Enviroseal).
Note that BAL – 40 and BAL – FZ do not permit the installation of roof mounted evaporative air
conditioners.
The enhanced unit for BAL – 12.5, BAL – 19 & BAL – 29 is identified with a sticker as shown below.
To account for the losses in air flow with the butterfly closer (Enviroseal) and the ember screen
fitted, consideration should be given in the system design and unit size selection to accommodate
losses. Air flow losses could be as high as 20% depending on the system design.
