Installation Advice

When fixed at 1 metre centres and at a minimum of 1 metre up from the eaves, a ventilation property equivalent to a 10mm continuous air gap is achieved.

Use product as supplied for the larger slate option (610 x 305mm).

Cut along guide lines for smaller slate option (510 x 255mm).

  • The two roof slates directly beneath the ventilator must be cut to accommodate the felt penetration sleeve on the rear of the slate vent (cut away the minimum possible to achieve a tight fit using the slate ventilator as a template).
  • Cut an X into the felt 200mm x 105mm at the point of the felt penetration sleeve.
  • Fold up/outwards the four triangles flaps to form an aperture of 200 x 105mm which will accommodate the sleeve.
  • Nail the top flaps over the battens.
  • Position the vent and nail into the batten through the nail slots provided.
  • Secure the front of the vent using a copper disc rivet.
  • Connect the pipe adapter kit to the underside of the slate vent if required.
