Ventilation systems

• The length of ducting and number of bends will effect performance and should therefore be kept to a minimum.
• Long runs of flexible duct are not recommended for use on cooker hoods.
• Ducting components have a simple push fit connection. Flat channel can be easily cut to length using a hacksaw.
• When installing a flat to round adaptor, it is important that the flat side is fixed uppermost. The flap operation of a grille/fan would otherwise be obstructed.
• When installing a circular through-the-wall duct a core drill can be used.
