Installation
Horizontal application
Horizontal applications will normally be used in an attic
plenum or duct to be connected to the supply collar and a
return air plenum or duct be attached to the unit inlet collar.
The supply ducts will be connected to the supply air plenum
and routed through the attic to a register in each room. Use
a Non-tape sealant such as mastic or an aerosol sealant to
prevent leaks in the ducts and the plenum.
The opposite end of the return air duct is attached to a return
tape sealant such as mastic or an aerosol sealant to prevent
leaks in the ducts and the plenum.
