INSTALATION
Drill a 25mm dia. hole through the external leaf at a slightly upward angle.
Position the front louvres horizontally using the ‘top’ marker on the flange as a guide.
Firmly push Rytons Retro Weep Vent into the pre-drilled hole, ensuring that the front louvres are kept horizontal at all times, until the external flange sits tight and flush with the wall (may be tapped lightly into position using a rubber mallet).
As cavity vents space according to current regulations at the top and bottom of the cavity wall to ventilate the cavity and assist in the drying out of the wall. Lower ventilators should be placed below the dpc, unless cavity trays are used when they should be positioned above the tray. Vertically stagger vents when placing them above and below horizontal fire stops.
As weep hole ducts space every fourth brick to drain cavities above and below the dpc, and above lintels and cavity trays. At least two weep holes should be provided over an opening, ie lintel.Installation
