Configuring the
room ventilation
opening
 Rooms in which rotary irons and tumble dryers are operated
must have an induced ventilation system (e.g., ventilation slots in
windows and doors, wall openings with grilles, or opened windows
or skylights).
For example1
A duct diameter of 6"(150mm) was specified in example1. Accord-
ing to this duct diameter, a room ventilation opening with a size of
17'5"(531cm) is required. The edge length is 91/16"(230mm) (see
Table3).
For example2
A total duct diameter of 811/16"(220mm) was specified. According
to this duct diameter, a room ventilation opening with a size of
37'4"(1,140cm) is required. The edge length is 1413/16"(377mm)
(see Table3).
For example3
Since in this case the tumble dryer is connected to a central air sup-
ply, additional ventilation openings are not needed.
