Fire dampers must be fitted as per national and local fire regulations.
Page 13 Installation Considerations Ducting 1. Connection of unit vents and ducts should be taped or sealed to prevent air leakage, and should com- ply to relevant guidelines and regulations. 2. The two outdoor vents should face downward toward the outside to prevent any rain water ingress. (angle 1/100 1/50).
