Make-Up Air Requirements

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.

Make-Up Air Dos and Don’ts

Do

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

NOTE: Each dryer pocket must have 40 square inches (260 cm2) 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.

Installation

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.
