Make-Up Air Requirements

It is important that the laundry room has adequate

make-up air for the dryer(s). A dryer exhausts 180 cfm

(measured at back of the dryer) and sufficient make-up

air must be supplied to replace the air exhausted by the

dryer.

Make-Up Air Dos and Don’ts

● Supply adequate air for ventilating air, drying air

and gas dryer combustion air.

NOTE: Each dryer pocket must have 260 cm

(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 or right of the dryer. EXCEPTION: Gas

dryers cannot be vented out the left side because of

the burner housing.

Unit is shipped from factory ready for rear exhaust; no

kits required.

Exhausting the dryer through sides can be

accomplished by installing a Directional Exhaust Kit

528P3 available as optional equipment at extra cost.
