1.1.1. Facade exhaust system (vertical facade)An NSHEV consisting of electromotive drive and the SHEV opening in the facade can, for example, be installedwith a chain drive or rack and pinion drive:Chain drive SHEV opening nSHEVRack and pinion drive SHEV opening nSHEVA wind sensitive control system is mandatory!1.1.2. Roof exhaust systemAn NSHEV consisting of electromotive drive and the SHEV opening in the roof can, for example, be installed witha rack and pinion drive:Rack and pinion drive SHEV opening nSHEVNSHEVs in the roof are subject to special installation conditions. These conditions are specified in Section 1.2.A wind sensitive control system is NOT required!The entire NSHEV must pass all individual tests in the facade and roof area. The tested components such as theelectromotive drive must not be replaced with other components.12Section A
1.2. Installation conditions for roof NSHEVsWe differentiate in general between two types of NSHEV in the roof:1. Single flaps with or without wind deflectors2. Dual single flaps with wind deflectorsNSHEVs as a single flap in the roof can be installed with and without wind deflectors and are subject to specialinstallation conditions. Single flaps can only be used in the roofs depicted. Minimum clearances are defined toensure that the NSHEV functions correctly. If these distances are not observed, the NSHEV no longer achievesthe specified aerodynamic efficiency.1.2.1. Single flap without wind deflectorsAt an angle of installation of [α] 30° to 45°Distance of the NSHEV to the roof ridge [dimension A]:Distance of the upper edge of the flap to the roof ridge [dimension F]:At an angle of installation of [α] 46° to 60°Distance of the NSHEV to the roof ridge [dimension A]:Distance of the upper edge of the flap to the roof ridge [dimension F]:750 mm ≤ A ≤ 1500 mm≤ 250 mm500 mm ≤ A ≤ 1500 mm≤ 500 mm1.2.2.

At nominal sizes of HCM ≤ 1.0 m, the entire opening angle range between 15° and90° can be used. The opening angle is limited to max. 30° for nominal sizes above HCM > 1.0 m.Section A13
