For Exhaust Duct more than 14 feet (5 m) and 2 elbows equivalent
and more than 0.3 inches (8 mm) static pressure.
1. Make-up air from outside building may enter enclosure from top
or side walls.
(See Dryer Make-Up Air Requirements Chart)
2. Use constant diameter duct with area equal to the sum of dryer
duct areas.
EXAMPLE:
6-8 in. (153-204 mm) diameter duct = 1-19.6 in.
(26-498 mm) diameter duct in area. Use 20 in. (508 mm)
diameter duct or diameter to match tube-axial fan.
3. Enclosure (plenum) with service door. This separates the dryer air
from 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:
110 lb. dryer, 2000 cfm (3400 m
3
/h) =
50,000 Btu/h (12,600 kcal/h) loss.
4. Zero inches clearance to combustible material allowed on sides
and at points within 4 inches (102 mm) of front on top.
5. Heat loss into laundry room from dryer fronts
only
is about
60 Btu/h (16 kcal/h) per square foot.
6. Flange mounted, belt driven tube-axial fan. Fan must run when
one or more dryers are running
.
See suggested Automatic
Electrical Control Wiring Diagram on page 23.
Must meet
local electrical codes. Fan air flow (cfm) is equal to sum of dryer
air flows, but static pressure (SP) is dependent on length of pipe
and number of elbows.
7. Barometric bypass damper—Adjust to
closed flutter position
with all dryers and exhaust fan running. Must be located within
enclosure.
CAUTION
Never
install hot water heaters or other gas appliances in the
same room as dryers.
Never
install cooling exhaust fans in the
same room as dryers.
CAUTION
Never exhaust dryers with other types of equipment.
