Always userigid-type metalductsonly.
Flexible ductscouldrestrict air flow by up to 50%,
Alsouse calculation (onright) to compute total

andcaps.
ALWAYS, when possible, reduce thenumberof
transitions andturns.If longductrun is required,
increase duct s izefrom6"to 7 or 8". If a reducer
is used, i nstalla longreducerinstead ofa pancake
