Planning notes
- Air extraction operation in combination with remote fan units AR 400/401 or recirculation mode with AR 413.
- Please refer to page xxx for recommended configurations of downdraft ventilations and remote fan units and the needed ducting elements.
- Maximum cooktop width between two VL: 60 cm.
Maximum distance between cut-outs: 5 cm. - The air baffle LS 330 000 is mandatory for installation next to gas appliances to avoid hazard of fire by saturated grease filters.
- Do not operate VL 431/430 next to VG 411 gas wok.
- When installing a ventilation hood with air extraction mode or recirculation outlet in another area of room air (e.g. cellar) and a chimney-vented fireplace, the hood's power supply line needs a suitable safety switch.
- Store the control electronics box (250 x 145 x 54 mm) for VL 431 in the lower cabinet.
- For installation in stone or light-coloured plastic worktops, use sealing tape (part No. 322793).
- For maximum duct lengths use Gaggenau flat rectangular ducts AD 8… or Naber-System Compair flow. Other flat ducts are not permitted!
- Duct connection downwards or sidewards:
DN 125 cylindrical included.
Optional DN 125/150 flat rectangular duct with connection piece AD 824/854 042 (installation accessory). - Connection of 2 VL with ducting
2x DN 125 cylindrical or 2x DN 125/150 rectangular at remote fan AR 4.. .
For leading through the floor DN 150 cylindrical with connection of 2 DN 125 cylindrical use Y-joint AD 754 044. - Please ensure when installing the exhaust air ducting that no sharp bends are caused and that the cross-section of the ducting is not constricted in any way.
- For downdraft configurations with maximum lengths of exhaust air ducts go to Rodun at www.gaggenau.com.
