Make-Up Air Requirements
It is important that the laundry room has adequate
make-up air for the unit(s). A dryer exhausts 180 cfm
(measured at back of the unit) and sufficient make-up
air must be supplied to replace the air exhaust by the
unit.
Make-Up Air Dos and Don’ts
Do
● Supply adequate air for ventilating air and drying
air.
NOTE: Each dryer pocket must have 260 cm
2
(40 square inches) of unobstructed flow of make-up
air for proper operation.
● Energy efficient buildings with low air
infiltration rates should be equipped with an air
exchanger that can accommodate on demand
make-up air needs in the laundry room. These
devices can be obtained through your building
contractor or building material suppliers.
Don’t
● Draw make-up air from a room containing a gas
fired water heater.
● Draw make-up air from a room containing a dry
cleaner or a hair salon.
Exhaust Direction
The dryer can be exhausted to the outdoors through the
back, left, right or bottom of the unit.
Unit is shipped from factory ready for rear exhaust; no
kits required.
Exhausting the unit through sides or bottom can be
accomplished by installing Directional Exhaust Kit
528P3, available as optional equipment at extra cost.
