PRIOR TO INSTALLATION
For optimum hood efficiency:
❑ Short, smooth duct pipe.
❑ As few bends in the ducting as possible.
❑ Diameter of ducting to be as large as
possible and no tight bends in ducting.
If long, rough exhaust-air ducting, many ducting
bends or smaller pipe diameters are used, the air
extraction rate will no longer be at an optimum
level and there will be an increase in noise.
IMPORTANT: The manufacturer of the hood
accepts no liability for complaints which can
be attributed to the design and layout of the
ductwork.
❑ Round pipes:
We recommend
Internal diameter: 6”.
❑ Flat ducts must have an internal cross-section that
equates to that of round pipes.
There should be no sharp bends.

❑ If pipes have different diameters:
Insert sealing strip.
❑ For exhaust-air mode, ensure that there is an
adequate supply of fresh air.
CONNECTING A l 6” EXHAUST-AIR DUCT:
❑ Mount the duct directly onto the air outlet on the hood.

Step 2: PREPARING THE WALL
❑ The wall must be flat and perpendicular.
❑ Ensure that the wall is capable of providing a firm hold
for mounting screws and plugs.
