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 soffit) and through the rear of the home. 150mm round ducting should be used in conjunction
with this model rangehood. Alternatively this rangehood can be operated in recirculation mode (see Recirculation
mode pg 6).
The highlighted area in the table below gives the recommended Uniduct item numbers for different
mounting and outlet options.

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.
Please note that this chart is designed as a guide.
