Whenever possible, install the ironer along an outside wall where duct length can be kept to a minimum, and
make-up air can be easily accessed. The construction must not block the airow at the rear of the ironer.
Doing so would prevent adequate air supply to the ironer combustion.
For maximum efciency, ironer air must be exhausted to the outdoors by the shortest possible route.
Never connect an ironer duct at a 90° angle to the collector dust (see picture below).
Doing so will cause excessive back pressure, resulting in poor performance.
Never connect two ironer exhaust ducts directly across from each other at the point of
entry to the collector dust.
