Installation
1. Fit to a combination airbrick by simply cutting the front section off between the pre-moulded cut lines and pushing on to the back of the brick (see diagram A).
2. Fit to a telescopic underfloor vent by pushing the adapter into the back, allowing a 4” soil pipe/drainage pipe to be fitted to the adapter (see diagram B).
3. Bricklaying should continue as normal although care should be taken to keep the airflow passage clear of mortar droppings.
4. If the square/round adapter is to be built in above DPC, a suitable cavity tray should be fitted over the ventilator.
5. Should be used in conjunction with a combination airbrick or a telescopic underfloor vent.
