INSTALL THE DUCTWORK
(DUCTED INSTALLATION ONLY)
NOTE: To reduce the risk of fire, use only metal ductwork.
1. Decide where the ductwork will run between the powerpack
insert and the outside. (FIG. 1)
2. A straight, short duct run will allow the powerpack insert
to perform most efficiently.
3. Long duct runs, elbows, and transitions will reduce the
performance of the powerpack insert. Use as few of
them as possible. Larger ducting may be required for best
performance with longer duct runs.
4. Install wall cap or roof cap (sold separately). Connect metal
ductwork to cap and work back towards the powerpack
insert location. Use 2” metal foil duct tape to seal the joints
between ductwork sections.
