ADDITIONAL INSTALLATION INSTRUCTIONS
Rangehood Installation
Exercise care when a rangehood is installed in an area where a gas burner is operating. Depending on the size of
the room, the rangehood may draw from the room air that is necessary for proper combustion of the burner. All
Blanco rangehoods are used for indoor application only.
Overhead Clearances.
Any combustible construction, rangehood or exhaust fan shall be installed accordance with the manufactures
instructions. However, in no case shall the clearance between the highest part of the HOB of the cooking appliance
(including the trivets for gas cookers) and a rangehood be less than 600mm or, for an overhead exhaust fan , 750mm
Rangehoods may be ducted in two ways:
1. Ducted to the atmosphere (outside).
2. Recirculating.
We recommend ducting to the atmosphere to ensure optimum performance. Recirculating the air back into the room
should only be used when outside extraction is not possible. To ensure maximum performance when ducting it is
important the ducting that carries the fumes away, be as short and as straight as possible.
When incorporating a rangehood in the design of a kitchen the following points need to be considered to
achieve the most benefit from the rangehood.
1. Ducting from a rangehood carrying the exhaust air, should not exceed a length of three (3) metres.
2. For ducted installation we recommend using galvanised or similar metal type flue pipe. PVC pipe is not
recommended.
3. Ducting containing a 90° degree bend will encounter a loss in efficiency of approximately 35%. Additional 90°
degree bends can cause losses of up to 15% per bend.
4. Ducting size should always comply with the manufacturers specification.
5. We recommend carbon filters be used when re-circulating the air into the room. There will be some loss of air
movement when carbon filters are fitted.
