Actual brick
Fitting Instructions
Preparation
Mark out the locations for the vents and drill a 25mm diameter hole through the external leaf of the wall into the
cavity at a slight upward angle at these points. Ensure that the hole is clear and free of debris before proceeding.
Installation
Align the tube with the hole, making sure to have the chevrons of the front grill pointing upward and the flat edge of
the drip feature horizontal, running parallel with the run of the wall. Push the vent firmly into the hole using the palm
of your hand until the back face of the flange sits flush against the substrate. As the ribs along the length of the tube
grip to hold the product in position it may require more force to push the vent into the hole, it is acceptable to gently
tap the vent into position using a rubber mallet.
Requirements
The vents can be positioned at high or low level to suit the required detail, and should be placed at both high and
low level to achieve a cross flow venitilated cavity if required. To suit the following requirements:
NHBC Standards 2008 - 650mm² free airflow every 1.2m - Space the G952 at 480mm centres.
Scottish Building Regulations 2007 - 300mm² free airflow every 1.2m - Space the G952 at 1m centres

Accepted Answer

They do not have an insect mesh however the louvered grill is designed to deter insects from entering the cavity.
