How To Install An Extractor Fan For The Kitchen

Installation Communication & Guide For Cooker Hoods & Extractors

Basic installation requirements for each type of extractor are detailed below:

Visor hood extractors:

The standard cooker hood is the most basic type and can be installed as a free-standing unit, or mounted underneath a bridging unit of measurement. All standard extractors can be used as extraction or re-circulation devices.

Integrated hood extractors:

These products are designed to supplant a bridging unit as role of a continuous run of units. Generally, the fixings for these extractors allow for some manual alignment both vertically and horizontal to line up exactly with the run of units. When fixing the fascia, care should be taken not to damage the runner mechanism.

Canopy hoods extractors:

Awning extractors are designed to fit into decorative chimney canopies. When installing these units, allowance should be made on the hinge side of the extractor and space provided for the filter encompass to swing down.

Chimney hood extractors:

Decorative chimney and designer extractors mount in a space between units. Normally, there should exist a gap between the edges of the extractor and whatever adjacent cabinets (50mm is typical). When installing these products, do not silicone to the wall and do not tile the products in; in the result of service beingness required, the product may need to exist removed from the wall.

Electric Connection

Annotation that nigh extractors are grade II protection against electric shock and exercise not require an earth.

Of import!

The isolation switch for whatever extractor should exist accessible after installation. The mains connection should non be made backside any fitted chimney sections unless a separate isolation switch is provided.

Extraction Rates & Venting

Any extractor should be capable of extracting between 6 and 12 times the volume of the room, which can be calculated as Room width 10 Room length x Ceiling superlative in metres and and then dividing the extraction charge per unit of the product by the volume calculated.

The maximum practical length of ducting is 6m and booster fans may be needed where the effective length is greater than this. When computing the effective length, assume whatsoever 90o bend is equivalent to 1.2m of straight ducting.

Glotech supplies a range of ducting through our EasiDuct range in 125 and 150mm sizes. The greater the ducting size, the more efficient the extractor will run, with lower noise.

Installation Heights When Fitted Above Hobs

When fitting extractors, the main consideration is the clearance summit betwixt the extractor and any hob fitted below. There is no minimum legal requirement when installing extractors above electric hobs, but the instructions for use supplied with both hob and extractor dictate the recommended minimum peak.

Notwithstanding, when fitting extractors above gas hobs the minimum top stated in the instructions booklets for both the hob and extractor needs to be met. Unless specific exclusions are specified in the extractor instructions then the higher of the heights given in the two instruction booklets must be used. In the case of gas appliances, failure to observe the correct installation requirements may lead to the installation being reported to RIDDOR and may delay whatsoever installation sign-off.

Important!

The width of any hob must not be greater than the width of the extractor installed to a higher place it. (Cylindrical & lantern mode extractors are the but exceptions)

Fixing the Unit to the Wall or Ceiling:

Some products are supplied with generic wall plugs and fixing screws. These may not be suitable for use with the wall or ceiling you wish to gear up the product to. Always ensure that yous utilise appropriate fixings. We cannot be held responsible for issues arising from wrong plumbing equipment to support surfaces.

When Using the Extractor as a Re-apportionment Device:

It is of import to remember that charcoal filters will exist required to remove any cooking odours if the extractor is to be used for re-apportionment but. Note that these volition crave periodic replacement (typically between iii and half dozen months).
