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
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
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 air flow
resistance equivalent, which should total less than 140 feet.
