It is important that the laundry room has adequate 
make-up air for the dryer(s). A dryer exhausts 220 cfm 
(measured at back of the dryer) and sufficient make-up 
air must be supplied to replace the air exhausted by the 
dryer.

●

Supply adequate air for ventilating air, drying air 
and gas dryer combustion air. 

●

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.

●

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.

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.
