• To convert areas to square meters (m2 ), multiply square feet by 0.0929.
• Single vent units: Frame must be ≤ 10 Ft2.
• Rough Opening = Frame Dimension + 1/2".
• Two high or two wide vent unit composites: Frame must be ≤ 20 ft2.
• Keep frame dimensions to the nearest 1/8" increment.
• Transom over vent composites: Lower unit frame must be ≤ 10 ft2.
• 48 Ft2 max size limitation
• Large Fixed over vent: Vent frame must be ≤ 10 ft2.
• Vent width > 29-1/2", the height must be ≤ 59-1/2
Maximum overall composite ≤ 32 ft2.
• Vent height > 59-1/2", the width must be ≤ 29-1/2 • Tempered glass must measure ≥ 18-1/2" diagonally. • If glass width to height ratio is > 5 to 1, then unit must be tempered. • Bronze annealed glass is limited to 22 ft2 glass size (actual glass).
