Hotpoint HTU30 manual Installing your Cooker Hood, MOUNTING Mounting Height, Thermal Cut-Out

Installing your Cooker Hood

NOTE: The hood is more efficient in the exhaust mode, therefore this position should be selected during the warmer months of the year when no heating is being used. When the room is being heated, if the recirculation position is selected heat will not be wasted.

MOUNTING

Mounting Height:

When installed above an electric cooking appliance the minimum distance between the surface of the hob elements and the lower grille of the cooker hood must be 650mm. When installed above a gas cooking appliance the minimum distance between the surface of the hob pan supports and the lower grille of the cooker hood must be 750mm.

The minimum distance for installation above a high level grill is 400mm.

The distance between the underside of adjoining wall cabinet and the worktop must not be less than 400mm.

If the cooker hood is installed for use above a gas appliance then the provision for ventilation must be in accordance with the gas safety (Installation and use) regulations. Detailed recommendations are contained in the following British Standard Codes of Practice BS6172, BS5440 and BS6891 Current Edition.

NOTE: This hood has been designed and approved for installation over an electric hob with a maximum input of 7kW or a gas hob with a maximum input of 10kW when fitted in accordance with the heights recommended above.

THERMAL CUT-OUT:

WARNING-The fan motor of this appliance incorporates a thermal cut-out device which will operate if the hood is installed below the minimum recommended heights listed above, or if the motor becomes overheated.

If the cut-out device is activated, switch off the fan motor and allow the hood to cool. The cut-out device will reset itself when the fan motor has cooled significantly.

Note: the hood is more effective when installed in extraction (ducting) mode.

Mounting beneath cabinets on the Wall: Before fitting the hood beneath any type of wall cabinet/canopy housing, ensure it is firmly fixed to the wall in accordance with the manufacturer’s instructions. Before drilling, care should be taken to check for electric cables, water pipes or gas pipes on the wall to which the cabinet/canopy is to be fitted.

The hood may be fixed to any rigid vertical surface. If the hood can only be fixed to a hollow construction plaster or partition board structure, then the wall must be sufficiently reinforced to be quite rigid in the area of the housing mounting system.

IMPORTANT: The exhaust air must not be expelled through a smoke or waste-gas chimney which is in use or through a shaft used for ventilating rooms or into the cavity of a cavity wall or into a cupboard above the cooker hood.

If the room contains a flued fuel burning appliance, such as a gas or oil fired central heating boiler which is not of the ‘Balanced Flue’ type, you should make sure that there is an adequate air inlet into the room at all times so that fumes from the boiler are not drawn back into the room by the cooker hood.

For secure operation and to prevent discharge gas from coming back in, the vacuum must not exceed 0.04mbr.

This may be done by making sure the air inlet into the room passes through non-closing openings such as air recycling wall boxes, doors, windows or with other technical measures.
