Product Information

Full details

The Manthorpe Adjustable Hit & Miss Air Vent Grille is designed for homeowners and DIY enthusiasts looking to manage airflow in internal spaces like larders, cupboards, and wardrobes. Its primary benefit is the intuitive sliding mechanism that allows for precise control over ventilation, helping to minimize drafts when full airflow isn't needed. However, it is important to note that this specific model is strictly for general ventilation and must not be used to ventilate gas appliances.

FAQs

Can I use this for a gas boiler?

No. This product is not safety-rated for the ventilation of gas appliances.

What are the dimensions of the aperture?

The grille is designed for a standard 9-inch by 6-inch (228.6mm x 152.4mm) brick opening.

Does it come with fixing screws?

Yes, it is designed for concealed screw-fixing to ensure a neat, professional finish.

What is the total free ventilation area?

The unit provides a free ventilation area of 4,680mm2.

Is the flyscreen removable?

The flyscreen is integral to the unit, meaning it is built into the design to prevent insect entry.

Can this be painted?

While the finish is a clean white, it is generally intended to be used as-is, though some users choose to use plastic-compatible spray paint.

Troubleshooting

The sliding mechanism feels stiff.

Check for debris accumulation within the tracks and wipe with a dry cloth to clear any obstruction.

The vent does not sit flush against the wall.

Verify that the wall surface is level and that no mortar or debris from the brickwork is preventing a flat contact.

Setup, Compatibility & Care

To install, ensure your wall aperture measures exactly 9 inches by 6 inches. The unit should be positioned over the opening, aligned, and secured using the appropriate screw fixings. Because the fixings are concealed, it is recommended to use the pilot holes provided on the frame to avoid cracking the plastic. Regarding care, the unit is low maintenance; simply wipe the surface with a soft, damp cloth to remove dust. If the flyscreen becomes clogged with fine debris over time, you may need to unscrew the unit to clear the mesh from the rear side, ensuring consistent airflow performance.
