Thermador HMCN42FS, HMCN36FS For optimum hood efficiency, CONNECTING A l 8” EXHAUST-AIRDUCT

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: 8”.

❑Flat ducts must have an internal cross- section that equates to that of round pipes.

There should be no sharp bends. l 8” approx. 50.3 inches2

❑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 8” EXHAUST-AIR DUCT:

❑Mount the duct directly onto the air out- let 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.
