6b.  Ducted mode (Fig.11)

 

 Insert flexible pipe and secure flue tape to air outlet 

with suitable duct tape.

 

 NOTE: For ducted mode we recommended to 

extend the flue pipe through the roof cladding(with 

appropriate flashing) to an external roof cowl, venting 

the exhaust externally.

 

 To ensure optimum performance of the rangehood, 

the use of bends should be avoided. Straight, rigid 

and short ducting is recommended to use. All ducting 

must be fire retardant.
