Provision must be made for enough air for combustion and ventilation. (Check governing codes and ordinances.) See “Recessed Area and Closet Installation Instructions” in the “Stacked Washer/Gas Dryer Location” and “Stacked Washer/ Electric Dryer Location” sections.
A 4" (102 mm) outlet hood is preferred. However, a 21⁄2"
(64 mm) outlet exhaust hood may be used. A 21⁄2" (64 mm) outlet creates greater back pressure than other hood types. For permanent installation, a stationary vent system is required.
