Step 2: Preparing The Wall - Thermador HMCB36FS Installation Manual

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 duct-
work.
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.
l 6" approx. 50.3 inches
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 out-
let on the hood.

Step 2: PREPARING THE WALL
