To minimise cracking, drill a pilot hole and then core

drill from both sides into the cavity.

NOTE: Horizontal ducting, including ducting in walls should

be arranged to slope slightly downwards away from the

internal grille to prevent backflow of any moisture into the

property.

Use a 102mm dia. Core drill for Airflow 100mm Wallvent.

Use a 127mm dia. Core drill for Airflow 125mm Wallvent.

Measure the wall thickness and cut the duct to length.

The tube should be flush to the inside and outside

surfaces.
