Dryer Installation With Separate Exhaust (Preferred)
For ductwork less than 14 feet (5 m) and 2 elbows equivalent and less than
0.3 inches (.8 mbar) static pressure:
NEVER exhaust the dryer into a chimney.
NEVER install wire mesh screen over the exhaust or make-up air
area.
NEVER exhaust into a wall, ceiling, or concealed space.
1. Make-up air opening from outside the building may enter the enclosure
from the top or side walls.
(See Dryer Make-Up Air Chart on page 22)
2. Enclosure (plenum) with service door. This separates the dryer air from the
room comfort air. If dryers use room air instead of outside air, additional
heat loss can be another 25 Btu/h (6.3 kcal/h) for each cubic foot per minute
(cfm) (.03m³/min.) used.
3. The installation clearance from all combustible material is 0" ceiling
clearance for the first 4" (102 mm) from the front of the dryer. After the
first 4" (102 mm), the ceiling clearance required is 6" (153 mm). The rear
clearance required is 0", and the side clearance is 0" .
4. Heat loss into laundry room from dryer front panels is about 60 Btu/h per
square foot (15 kcal/h per 0.1m²).
