3. MAKE-UP AIR. Adequate make-up air must be supplied to replace air exhausted by
dryers on all types of installations. Provide a minimum air opening to the outside for each
dryer as follows:
Dryer Model Make-up Air Volume/Time Make-up Air Opening Size (minimum)
DN0030E_ 690 CFM (19.5 m
3
/minute) 1 ft² (0.10 m
2
)
DN0050E_ 700 CFM (19.8 m
3
/minute) 1.25 ft² (0.12 m
2
)
DN0080E_ 850 CFM (24.1 m
3
/minute) 1.25 ft² (0.12 m
2
)
This is a net requirement of effective area. Screens, grills or louvers, which will restrict the
flow of air, must be considered. Consult the supplier to determine the free area equivalent for
the grill being used.
The source of make-up air should be located sufficiently away from the dryers to allow an
even airflow to the air intakes of all dryers. Multiple openings should be provided.
The operation of this appliance may affect the operation of gas appliances, which take their
air for safe combustion from the same room. Adequate ventilation must be provided to avoid
back flow of gasses from other appliances in the same room. All gas appliances should be
tested with the Dexter dryer in operation and all the windows and doors closed. If in doubt,
consult the appliance manufacturer(s).
