available duct run when using elbows, transitions

and caps.

ALWAYS, when possible, reduce the number or

transitions and turns. If long duct run is required,

increase duct size.

If turns or transitions are required; install as far

away from insert duct output and as far apart,

between the two as possible.

Minimum mount height between range top to

cabinet bottom should be no less than 26”.

Maximum mount height should be no higher than

36”.

It is important to install the liner at the proper

mounting height. Liners mounted too low could

dimensions in FIG. 1.

3. Install liner into custom hood. FIG. 2, Page 11.

WARNING: Make sure the surface you are securing the

liner to is capable of holding the weight of AK90. Failure

to do so may cause personal injury or damage to cooking

surface or counter. Wood blocking may need to be added

to cabinet base if additional support is needed.

4. Secure front panel to custom hood. FIG. 3, Page 11
