Viking DTWN - Manual (Page 4)

Proper installation/ducting is extremely
important to ensure maximum
performance. Use a qualified and
trained installer.
DUCTING
• Check with a qualified and
trained installer or local codes
for makeup air requirements, if
any.
• Max. duct run length
o For 300 – 1,200 CFM—50’
(152.4 m)
o For 1,500 CFM—75’ (22.9 m)
o 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” (17.8 cm) round duct for
300 – 600 CFM; 10” for 900 –
1500 CFM
o Never use flexible duct; it
creates back pressure/air
turbulence and greatly
reduces performance.

Installation Requirements
* A 1,200 CFM interior- or exterior-power ventilator should be used when installed over range/rangetop with gas char-grill.
** It is recommended that the 1,500 CFM ventilator be used with longer duct runs.
Note: Maximum amp rating for hoods includes recommended ventilator kit rating. All products must be hard wired with two-wire ground. An interior- or
exterior-power ventilator kit must be purchased for installation with all 18”H. hoods.

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.
