Dryer Installation With Separate Exhaust (Preferred)
DRYER INSTALLATION
WITH SEPARATE EXHAUST
(PREFERRED)
For ductwork less than 14 feet (5) and 2 elbows equivalent and less than
0.3 inches (7.7 mm) 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 Requirements
Chart)
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 6" (153 mm) 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).
