■

Wherever possible, reduce the number of transitions and turns to as 

few sharp angles as possible. Two staggered 45° angles are better 

than one 90°. Keep turns as far away from the hood exhaust as 

possible, with as much space between each bend as possible.

 

■

For best performance, use round duct instead of rectangular when 

possible, especially when elbows are required.

 

■

If multiple elbows are used, try to keep a minimum of 24” of straight 

duct between them. Avoid “S” or “back to back” configurations of 

adjacent elbows.

 

■

Do not use flexible metal duct.

 

■

Do not use duct work that is smaller in cross-sectional area than the 

required duct sizes in the table to the right.

 

■

For best performance, keep the duct run as short as possible and 

never exceed the maximums stated at the right.

 

■

The maximum straight duct length for the raised vent system depends 

on the model of remote or in-line blower used with the vent system 

and the number of elbows and transitions used. The Equivalent 

Number of Feet for each elbow and transition (see table) must be 

subtracted from the maximum straight length to compensate for 

wind resistance. To determine the maximum allowable length of the 

duct work, subtract all of the equivalent lengths of the elbows and 

transitions from the Blower Maximum Duct Straight Length.

 

■

From the Blower Maximum Duct Straight Length table, the 

maximum length without transitions and elbows is 60 feet.

 

■

The equivalent length of each 90

° elbow is 15 feet.

 

■

The equivalent length of 45

° elbow is 2 feet.

 

■

The equivalent length of the transition is 4 feet.

 

■

The total equivalent length of the above components is: 15 feet + 15 

feet + 4 feet + 2 feet = 36 feet.

 

■

The maximum amount of straight duct that can be used with a 

REMP16 and the above components is: 60 feet - 34 feet = 24 feet.
