Viking VWH - Manual (Page 5)

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
o For 300 – 1,200 CFM—50’
(15.2 m)
o For 1,500 CFM—75’
(22.9 m)
o Duct run length is for
general reference only;
always use 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 for 300 – 600
CFM; 10” for 900 – 1500 CFM
o Never use flexible duct; it
creates back pressure/air
turbulence and greatly
reduces performance.
GAS

ELECTRICAL
• Hardwire direct with two-wire
with ground

* 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 2-wire with 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.
