Connection for air extraction
Important: To avoid the danger of toxic fumes, please observe the Warning and Safety instructions. This is especially crucial when using the rangehood at the same time as another heating appliance which relies on air from the same room. The rangehood should be installed according to local and national building regulations. Seek approval from the building inspector where necessary.
–Only use smooth pipes or flexible hoses made from
–When using an external motor, make sure that the exhaust ducting is sufficiently rigid. The external motor can cause an underpressure which can result in the exhaust ducting distorting.
To achieve the greatest possible air extraction with the lowest noise level, please note the following:
–To ensure efficient air extraction, the diameter of the exhaust ducting should not be less than 150 mm.
–If flat ducting is being used, the
If exhaust ducting with a diameter of less than 150 mm, or if flat ducting is used, the noise level of the rangehood will increase and extraction will be less efficient.
–All ducting, pipework and fittings must be of
–The exhaust ducting should be as short and straight as possible.
–Only use wide radius bends.
–The exhaust ducting should not be kinked or compressed.
–Ensure that all connections are strong and airtight.
