Pre-Installation Instructions
Ducting Options
The method of ducting should be carefully considered before installing the rangehood. The guide below
recommends the ducting components to use for all common ducting configurations - through the top of the
home (for the roof and eaves) and through the wall of the home. It is recommended to use the 2M Ø180mm
flexi ducting included and the Ø 180mm wall duct outlet. This will achieve the best extraction rate and
lowest noise level for the hood. In situation where a 150mm outlet is required then the 180mm to 150mm
adaptor can be used at the end of the 2M x 180mm flexi ducting that is included with this rangehood. From
here 150mm ducting can be used to carry through to the outlet to enable fitment of the required 150mm
duct outlet. If Ø180mm ducting can be used the entire way, this will achieve the best possible result for
these rangehoods. NOTE: These rangehoods cannot be operated in recirculation mode.
Extra lengths and/or bends may be required, depending on the length required and whether there is any
structural material in the run e.g. rafters. As stated above, if additional ducting is required then Ø180mm is
optimal but 150mm can be used in conjunction with the 180mm ducting supplied via the use of the 180mm
to 150mm adaptor. NOTE: The shorter the duct length, the better the performance.
