    Product Description

    The Manthorpe 5" Core Drill Vent G900 is designed for use when ventilating a gas appliance, but can also be used for general through wall ventilation.

    The vent can easily be fitted in both refurbishment and new build situations with the use of a 5" (127mm) diameter core drill.

    The kit includes a cowl vent for exterior use, a louvre grille for inside, a 350mm length of pipe duct and an optional anti-draught baffle. This baffle reduces the airflow and also the feel of a draught through the vent.

    The external cowl minimises uncomfortable draughts, reduces noise and light from outside the property and acts as a barrier against wind driven rain whilst providing a free area of 100cm² and is available in both brown and terracotta.

    The Louvre fits on the internal wall and, similarly to the cowl, reduces draughts, noise and light penetration, while providing a free area of 100cm², it is only available in white.

    The G901 large back plate vent covers any masonry damage caused whilst creating the hole for the pipe whether this is with the use of a core drill or by chopping out with a masonry chisel.

    Key Features

    • 100cm² of airflow without draught baffle
    • 70cm² effective airflow with baffle
    • Suitable for ventilating gas appliances
    • Fits through a 5" diameter core drill hole

    Fitting Requirements

    Using a 5" (127mm) core drill and a suitable power drill, cut a hole through the entire thickness of the wall. Feed the pipe through the hole, cut to length where required and insert the baffle is necessary.

    Screw the backplates into the outer wall and inner plasterboard. Align and clip the cowl and louvre grille over the backplates.
