•
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).
