Acoustic Vent Sleeve Installation Guide
Introduction
The purpose of this document is to give guidance to approved contractors and suppliers who are engaged in the fire stopping of service penetrations in fire rated structures using the Astro Acoustic Vent Sleeve
All service holes through ceilings must be fire stopped to prevent the passage of fire, smoke and hot gases.
Prevent the spread of fire, smoke and hot gases through a building by containing it in the compartment of origin.
Maintain the integrity of escape routes from a building.
Reduce loss or damage to property from the effect of fire and smoke.
Maintain pressure differential between compartments and ventilation channels.
The Astro Acoustic Vent Sleeve
The Astro Acoustic Vent Sleeve has been developed to provide maximum protection for holes created by the introduction of the most popular sizes of polymeric recessed ceiling fans and vents with minimal installation time.
In a fire situation, the sleeve expands internally to crush the spigot of the fan / vent and create an effective barrier against both heat and flames. Unlike other “Intumescent” materials the Astro Acoustic Vent Sleeve do not need additional support and will only expand inwards.
Installation
Step
One
Use OD of sleeve as a template and cut a hole in ceiling to provide a snug fit
Step
Two
* Place sleeve and spigot extension, if required, onto the fan / vent spigot.
* The spigot extension is not required unless the spigot length of the fan / ventis not long enough to attach to the hose or rigid ducting with the sleeve fitted. The spigot extension can be shortened for “tight” ceiling voids.
Step
Three
Attach flexible hose to spigot.
Step
Four
Ease the fan and sleeve into the ceiling cut out and locate with rigid ducting if required. Attach fan / vent to ceiling in the normal way.
