Ductwork Installation - Friedrich VRP Series Installation & Operation Manual

Ductwork Installation

Supply air duct connection is the responsibility of
the installer and should be installed per industry
best practices.
Sheet metal or duct board may be used for the
transition from the discharge to 10" or larger
diameter flexible ducting.
Avoid sharp transitions in the ductwork to ensure
optimal indoor blower performance.
Allow at least 12" (18" preferred) from the
discharge of the unit to the final reduced-size
transition to support optimal efficiency of the
blower system.
