HOOD EXHAUST DUCT

When the hood is vented to the outside, a hood
exhaust duct is required. All ductwork must be
metal; do not use plastic duct. Check that all con-
nections are secure. Please read the following
carefully:

Exhaust connection

The hood exhaust has been designed to connect
to a standard 3 ⁄ in x 10 in (82.5 mm x 254 mm)

rectangular duct. If round duct is required, a rect-
angular-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 accommo-
date the exhaust.

Maximum duct length

For satisfactory air movement, the total duct
length of 3
rectangular or 6 in (152 mm) diameter round duct
should not exceed 140 feet (42.67 meters).
Elbows, adapters, wall and roof caps present ad-
ditional 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 tran-
sitions 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 (42.67 meters).
