DETERMINING REMOTE BLOWER DUCTS AND FITTINGS

High levels of air flow provide better performance.  For
best results, use larger duct and keep the duct length as
short as possible.

The VTR1000Q remote blower requires a 10" diameter
round duct to match the inlet ring.  You will need to transition
from other duct sizes to achieve the 10" diameter.  Be sure
to use proper transitions from one size duct to another.

NOTE:   You need to calculate the equivalent lengths of
straight duct for each elbow or transition you use. See
Blower Duct Sizing Section, Page 15 to 17.

Select type of adapter (Figure 21) based on ducting
options (Fig 22).
