Planning Information

Proper installation of ducting is extremely

important to ensure maximum performance

from any ventilation product.

•

All CFMs are based on tests at 0.1 static

pressure: without applying static pressure, CFM

would be greatly overstated.

• Straight runs and gradual turns are best; for

example, each 90º elbow is equivalent to 5-10

feet (1.52-3.05 cm) of straight run.

• Never use flexible duct; it creates back pressure/air

turbulence and greatly reduces performance.

• Proper performance is dependent on proper

ducting; make sure that a qualified and trained

installer is used.

• Check with a qualified and trained installer or

local codes for makeup air requirement, if any.

• Max. amp rating for hoods includes

recommended ventilator kit rating; all products

must be hard wired direct with 2-wire with ground.

Plan where the duct work will be located. Install

proper-sized duct work, and roof or wall cap for the

type of blower you are using. Recommended hood

locations for the most common installations are

shown. Adjust your measurements for various heights

of ceilings, soffits, cabinets, or ranges/rangetops.

Check Framing

NOTE: Because of the weight of the hood make sure

that the mounting screws are driven into the framing

and not just the drywall. It may be necessary to drill

additional holes in the canopy for proper alignment.

Electrical Supply

Run 120 VAC electrical wiring from service panel

to installation location. See Specifications pages

for the maximum amp requirements.
