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 cm
2
) 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.
