Installation

Vent system must terminate to the outside
(roof or side wall).
DO NOT terminate the vent system in an
attic or other enclosed area.
DO NOT use 4” (10.2 cm) laundry-type
wall caps.
Use metal/aluminum ducting only. Rigid
metal/aluminum ducting is recommended.
Always keep the duct clean to ensure
proper airflow.
Calculate the following figures before
installation:
1. Distance from the floor to the ceiling.
*(less than 108").
2. Distance between the floor to the
countertop/stove. (Recommend* 28”
to about 36”).
3. Distance between the countertop/stove
to the range hood. (Recommended 28"
to ~31").
4. Height of range hood body and chimney
covers combined. (Extension available*)
A distance of 28” to 31” is recommended
between stove top and the bottom of
range hood.
"28" is the lowest recommended for safe
operation; 31" is only recommended for
efficient operation, but can be mounted
higher."
It is recommended that the range hood be
vented vertically through the roof through
6” (15.24 cm) or larger round
metal/aluminum vent work.
The size of the vent should be uniform.
Use no more than three 90° elbows.
For best results, attempt to make a
minimum of 24" (61 cm) of straight vent
between the elbows if more than one
elbow is used.
DO NOT install two elbows together.
The length of vent system and number of
elbows should be kept to a minimum to
provide efficient performance.
The vent system must have a damper.
If roof or wall cap already has a damper,
DO NOT use the supplied damper
(if applicable).
