DRYER INSTALLATION WITH SEPARATE EXHAUST (PREFERRED)
DRYER INSTALLATION WITH SEPARATE EXHAUST
(PREFERRED)
For Exhaust Duct less than 14 feet (5 m) and 2 elbows equivalent
and less than 0.3 (8 mm) inches 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, the heat loss can be another 25 Btu/h (6.3 kcal/h) for
each cubic foot per minute (cfm) used.
EXAMPLE:
A 125 lb. dryer with 2000 cfm (3400 m 3 /h) = heat
loss of 50,000 Btu/h (12,600 kcal/h).
3. Zero inches clearance to combustible material allowed on sides
and at points within 4 inches (102 mm) of front on top.
4. Heat loss into laundry room from dryer fronts only is about
60 Btu/h (15.2 kcal/h) per square foot.
