4. HOOD EXHAUST DUCT
When the hood is vented to the outside, a hood exhaust duct is required. All ductwork
must be metal; absolutely do not use plastic duct. Check that all connections are made
securely. Please read the following carefully:
Exhaust connection: The hood exhaust has been designed to connect to a standard 3-1/4"
x 10" rectangular duct. If round duct is required, a rectangular-to-round adapter must be
used.
Rear exhaust: If a rear or
horizontal exhaust is to be used,
care should be taken to align the
exhaust with the space between
the studs, or wall should be
prepared at the time it is
constructed by leaving enough
space between wall studs to
accommodate exhaust.
Maximum duct length: For
satisfactory air movement, the
total duct length of 3-1/4" X 10" rectangular or 6"diameter round duct should not exceed
140 feet.
Elbows, adapters, wall, roof caps, etc. present additional resistance to air flow and are
equivalent to a section of straight duct which is longer than their actual physical size.
When calculating the total length, add the equivalent lengths of all transitions and
adapters plus the length of all straight duct sections. Figure 4 shows the approximate feet
of equivalent length of some typical ductwork parts. Use the values in parentheses for
calculating airflow resistance equivalent, which should total less than 140 feet.
5. TOOLS RECOMMENDED FOR INSTALLATION

1-1/2" Wood Bit or Metal Hole Cutter (if metal cabinet is used)
