DUCTING SYSTEM
DUCT REQUIREMENTS
The supply duct system, including the number
and type of registers, will have much more
effect on the performance of the system than
any other factor. The duct must be suffi ciently
large to conduct an adequate amount of air to
each register.
Air ducts should be installed in accordance
with the standards of the National Fire Protec-
tion Association "Standard for Installation of Air
Conditioning and Ventilation Systems" (NFPA
90A), "Standard for Installation of Residence
Type Warm Air Heating and Air Conditioning
Systems" (NFPA 90B), these instructions, and
all applicable codes.
