Viking DCH - Manual (Page 4)

Proper installation/ ducting is
extremely important to ensure
maximum performance. Use a qualified
and trained installer.
DUCTING
• 460 CFM interior (blower
included)
• Check with a qualified and
trained installer for local
codes and makeup air
requirements, if any.
• Max. duct run length—50’
(152.4 m)
o Duct run length is for
general reference only;
for longer duct runs,
increase duct size and
contact a qualified and
trained installer.
o Straight runs and
gradual turns are best; for
example, each 90° elbow
is equivalent to 5’ – 10’
(1.52 – 3.05 cm) of
straight run.
• 7” round duct
o Never use flexible duct; it
creates back pressure/air
turbulence and greatly
reduces performance.

Note: All CFMs are based on tests with 0.1 static pressure. Without applying static pressure (some brands do not), CFM could be
greatly overstated.
