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 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). Space according to current regulations at the top and bottom of the wall to ventilate the cavity and assist in the drying out of the wall. Lower ventilators should be placed below the dpc. Where cavity trays are used position above the tray. Vertically stagger vents when placing them above and below horizon¬tal fire stops. As weep outlets space every fourth brick to drain cavities above and below the dpc and above lintels and cavity trays.
