The cooktop is equipped with a dual-range
blower. The blower is factory-set to operate at
the “Low” range (equivalent duct lengths of
30-feet (9.1 m) or shorter. If the equivalent
duct length exceeds 30-feet, the blower must
be set to operate at the “High” range (see page
1-9).
Do not change the blower to “High” if
the equivalent duct length is under 30-feet.
This will cause excessive noise and condi-
tioned air loss.
To use the following chart, list the number of
each piece, and the length of straight ductwork
that you intend to use. Multiply the equivalent
length by the number of pieces. Add the totals
to get the total equivalent length of your duct
system. Two duct system configuration ex-
amples are shown on the following page.
