• A minimum of 8” round (standardforthisrangehood)rectangularduct6”x10”(purchasedseparately)

mustbeusedtomaintainmaximumairowefciency.

• Alwaysuserigidtypemetal/aluminumductsifavailabletomaximizeairowwhenconnectingtoprovided

duct.

• PleaseuseDuct Run Calculation below to compute total available duct run when using elbows, transitions

and caps.

• ALWAYS,whenpossible,reducethenumberortransitionsandturns.Iflongductrunisrequired,increase

ductsizefrom8”to9”or10”.Ifareducerisused,installalongreducerinsteadofapancakereducer.Re-

ducingductsizewillrestrictairowanddecreaseairow,thusreduceductsizeasfarawayfromopeningas

possible.

• Ifturnsortransitionsarerequired:Installasfarawayfromopeningandasfarapart,between2,aspossible.

• Minimum mount height between stove top to hood bottom should be no less than 28-inch*.

• Maximummountheightbetweenstovetoptohoodbottomshouldbenohigherthan36-inch*.

• Itisimportanttoinstallthehoodatthepropermountingheight.Hoodsmountedtoolowcouldresultinheat

Duct Run Calculation:

Recommendedmaximumrun

8” 50 ft

Ventpiecededuction

Each90ºelbowused 9ft

Each45ºelbowused 5 ft

Each8”to3/14x10”transitionused 7ft

Sidewallcapwithdamper 0 ft

Roof cap 0 ft

Duct Run Calcuation example:

One roof cap, two 90º elbow, and one 45º elbow used:

0ft + 9ft + 9ft + 5ft = 23ft used.

Deduct 23ft from 50ft, 27ft maximum available for

straight duct run.
